EN 16755 - Durability of reaction to fire performance - Classes of fire-retardant treated wood products in interior and exterior end use applications.

 Purpose/Benefit:

Multi-storey buildings with wooden facades need to fulfil the requirements in SP FIRE 105 in Sweden. The requirements should be fulfilled also when the wood has been exposed to the surrounding climate.

To ensure that your product is up to standard during its life cycle, the product shall be tested according to EN 16755 - Durability of reaction to fire performance.

This means that your product is undergoing the hygroscopicity test and accelerated weathering. Before and after accelerated weathering it is fire tested according to the SBI method.

 Method (what/which methods are used to perform the service):

EN 16755 - Durability of reaction to fire performance - Classes of fire-retardant treated wood products in interior and exterior end use applications.

EN 13823 - Single Burning Item (SBI).

In accordance with EN 16755:2017, the SBI method (EN 13823) is the preferred evaluation method to validate the durability of reaction to fire performance of products meant for exterior applications. Alternatively, it is possible to use the cone calorimeter (ISO 5660-1). However, due uncertainties regarding the achieved level of safety when using the cone calorimeter, RISE has chosen to NOT offer this alternative testing method until further notice. EN 16755:2017 is currently under revision and the cessation will apply at least until the new standard is ratified. Henceforth, RISE will only offer validation trough the SBI method.

Prefabricated wet room modules

Name of service (page headline, shown in promos – maximum of 70 characters incl. spaces): Prefabricated wet room modules Lead (include SEO-words and the main benefits for your target groups. Stick to one paragraph, maximum 2-3 sentences):

Today it is common to use prefabricated wet room modules as an alternative to a in site-built bathroom in new building projects. It is then important to set the right requirements for the design and that the entire wet room module is tested and approved according to our Swedish rules.

 Purpose/Benefit:

It is of course extremely important that the finished wet room module is waterproof and there is no leakage of water at penetrations, wall and floor angles, floor drain, fixings or linking. It is also important that the different materials are compatible with each other and do not cause corrosion or other damage.

RISE has extensive expertise and services in the prefabricated wet room area, some examples include:

  • Watertight and load tests according to ETAG 022. Water spray of floors, walls, penetrations that is, everything where there is a risk of leakage. Load of pipe penetrations and suspension devices, all to mimic real use.
  • Corrosion resistance and compatibility between different materials
  • Moisture calculations of different design designs
  • Damage investigations

We work with type approval of prefabricated wet room modules. Type approval is a national system for assessing and verifying the conformity of construction products with requirements in Swedish building regulations. This means that the construction product is assessed in the aspects expressly stated in the type-approval, by references to the Planning and Construction Act and sections of  – The Swedish National Board of Housing, Building and Planning's Building Regulations.

A type-approval helps the developer to certify that the construction product meets the requirements of the Swedish building regulations. RISE publishes type approval and the associated document, usually the installation instructions.

The holder may refer to type approval to show that the product is tested and certified by a third party and complies with Swedish building regulations.

 Method (what/which methods are used to perform the service):

A test method used for function testing of wet room modules is: EAD 030352-00-0503 combination of Annexes A and E (former ETAG 022).

Type approval of wet room modules takes place according to CR 136 Certification rule for type approval of prefabricated wet room modules.

 Delivery (what does the client get after performed service – e.g. a report, certificate etc.):

Tests are presented in a test report.  In the case of type-approval, a certificate is issued.

Airtight climate shells under real conditions Stages 1 and 2

Airtight climate shells
Test wall

Energy-efficient buildings need to have an airtight climate shell that works for a long time. In order to avoid costs and hassle with changing products that are built into the construction, it is important to be able to assess in advance how the sealing system is expected to last in the long run. This research project has resulted in a method and t

The climate shell's airtightness system is absolutely crucial for near-zero energy houses, passive houses and plus houses to function as intended. Houses are built for decades of trouble-free use. It is therefore required that sealing systems do not lose their properties after a few years, but that the airtightness is preserved over a long period of time. To achieve airtightness, polymeric materials are normally used which are more sensitive to aging than most other building materials. The stability over time is determined by the composition and structure of the polymeric material as well as how it is manufactured and stored. Factors such as the surrounding environment are also important for the long-term properties. Since the products that ensure the airtightness are usually built into the construction, premature replacement can mean major and costly interventions in the buildings. Therefore, it is desirable to be able to evaluate in advance, in a laboratory environment, the durability of the various air sealing systems. For this, a testing method is needed.

The overall aim of this E2B2-supported research project is to develop a method by which whole systems of airtightness can be investigated. The goal is good air tightness and low energy consumption over a long period of time with the air tightness system of the future. As a continuation of the previous partial application, a method and test bed has now been developed to ensure that the materials and combinations of materials included in the climate shell have good tightness even after decades of use. The testing method has proven to work well. By, among other things, exposing the materials to temperatures of 60 °C to 80 °C, an intended service life of 25-50 years has been simulated. Construction site conditions matter In addition to the materials, the conditions of the construction itself, which are not always ideal, play a role in durability. Within the scope of the project, assembly of airtightness systems has therefore been done in environments chosen to mimic realistic construction site conditions.

Important results
• Since the systems that ensure the airtightness of buildings are built into the construction, their long-term durability is absolutely crucial. Switching is often expensive and complicated.
• By examining in advance the airtight materials and material combinations included in the climate shell, it is possible to choose a solution that also lasts in the long term.
• Although the three different makes of air tightness systems tested in the project have good air tightness, below 0.1 l/(s∙m²), accelerated aging in all cases shows an increasing air permeability.
• Construction site conditions, which can be anything but ideal, also play a role in durability. Changes in air tightness are noted when assembly took place in a cold, damp and dusty environment.
• Climate shells that deteriorate with age are a bad deal. An air leak that increases from 0.3 to 0.9 l/(s∙m²) drives energy use up by 15 percent.

Test method for function and durability of rain and wind protection

Rain and wind protection in a real envir
Test wall

That the rain and wind protection on property facades works well is important from an energy point of view, because leaky facades leak energy. In many accepted methods of testing products for rain and wind protection systems, testing is done under favorable conditions.

Division: Do not use - Division Built Environment

In RISE's test lab in Borås, the researchers in this project have put the rain and wind protection to the test. If this layer does not work well, the insulation material risks getting wet or the wind can blow through the insulation material. This in turn leads to the insulation material losing its insulating ability, with high energy consumption as one of the consequences.

At RISE, researchers in previous projects within E2B2 have studied the air density in the climate shell. In this project, they have studied the layer outside the insulation. In many accepted methods of testing products for rain and wind protection systems, the tests of the products are carried out under favorable conditions of normal indoor temperature and humidity. In this project, the method has been supplemented, so that tests are also carried out in environments that resemble realistic construction site conditions. Tests have been carried out in three different environments: ideal conditions (normal lab climate), in a cold and humid environment, approximately 5°C 90–95 percent relative humidity and in a dusty environment.

The researchers have carried out tests of three different rain and wind protection systems from different manufacturers. The systems included foil, tape, cuffs for grommets and seam sealing.

The testing method has worked well in the pilot tests. It is possible to see a change in the air density during measurements before and after the heat treatment. The three rain and wind protection systems tested were very airtight, which is good from an energy point of view.

The heat treatment gave slightly different results. Some measurements showed increased leakage after the heat treatment, while other measurements showed reduced air leakage after the heat treatment.

When subjected to rain and gusts of wind, all three rain and wind protection systems had leakage - but to different extents. The fact that the rain and wind protection systems are not completely waterproof is not good because it is one of the prerequisites for being able to maintain a low energy consumption in the long term. It can also be a problem as the rain and wind protection systems are sometimes used instead of a separate weather protection on a construction site.

Important results

  • A new method has been developed and tested for rain and wind protection systems. In the new method, the systems are also tested in realistic construction site conditions. 
  • The method has worked well in the pilot tests. You can see a change in the air density when measuring before and after the heat treatment. 
  • All three tested rain and wind protection systems are very airtight. This means that you can get a substantial improvement in air tightness and thus lower energy consumption in buildings where the investigated air tightness systems are used. 
  • The heat treatment gave slightly different results, some measurements showed an increased leakage after the heat treatment while other measurements showed a decrease in air leakage after the heat treatment. 
  • All the the investigated rain and wind protection systems showed leakage in tests in combined rain and wind. 
  • If the facade is not rainproof, the insulating material gets wet and thus loses its insulating ability.

Real time sensing of temperature and chemistry in molten metal

Continuous measurement of temperature and composition in molten metal provides opportunities for better use of energy and raw materials.

Good process control is crucial for quality, efficiency and safety in the production and processing of metal. However, developing measurement systems for this environment is a challenge. High temperatures and a corrosive and dirty atmosphere put high demands on the sensor systems to be used.

A typical metallurgical process today monitors the temperature using thermocouples, in this case a disposable sensor. The chemical composition is typically studied using sampling and chemical analysis in a laboratory. Both of these measurement methods provide a snapshot of temperature and material composition at the time and place where the sample was taken. No information is given about variations in temperature and composition over time and over the melt.

The ability to continuously, and in real time, monitor these parameters is of great interest in the metallurgical industry. Continuous real-time measurements of temperature and chemical composition in molten metal could contribute to higher efficiency (eg lower energy consumption, lower raw material consumption), better steel quality, higher safety and could possibly also enable a higher use of recycled materials in the processes.

RISE and partners have previously developed systems for continuous monitoring of temperature and chemistry, specially adapted for metallurgical processes.

Continuous temperature measurement: BST (Broad Band Spectral Thermometry) is a method where process radiation from the melt is collected and its optical spectrum analyzed to determine the process temperature. The principle is the same as for pyrometers, but with the important difference that BST analyzes a wide optical spectrum, which makes the technology considerably more robust, and enables measurements in environments and processes where pyrometers cannot be used. BST can also provide other important information from the process, such as the presence of alkalis. By using fiber optics, the process radiation can be collected directly from the process. Read more about BST. 

Continuous analysis of chemical composition: LIBS is a well-established method for analyzing chemical content in materials. A high-energy laser pulse is fired at the material to be analyzed. The laser light creates a local plasma where the content of the material is revealed by specific lines in the plasma spectrum. Read more about LIBS.

In this project, the next step was taken towards the commercialization of these measurement systems. Internationally leading metallurgical industry, Zanardi (Italy) and Sandvik Materials (Sweden, now Alleima), test the systems in their metallurgical processes and Agellis (now part of RHI Magnesita), a Swedish measurement technology company with leading solutions for the metallurgical industry, validates the commercial potential.

 

This project received funding from EIT RawMaterials, initiated and funded by the European Institute of Innovation and Technology (EIT), a body of the European Union, under the Horizon 2020, the EU Framework Programme for Research and Innovation.

Jet fire test

Name of service (page headline, shown in promos – maximum of 70 characters incl. spaces): Jet fire test Lead (include SEO-words and the main benefits for your target groups. Stick to one paragraph, maximum 2-3 sentences):

We have a long experience in jet fire testing and has been involved in the development of several jet fire test standards used by the industry and the authorities today. Our facility enables testing of complex combinations of one or several jet fires with varying heat flux levels.

 Purpose/Benefit:

Jet fires represent a major fire risk in installations with pressurized hydrocarbons. Jet fires may vary with respect to flame length, heat flux and velocities, and important influencing factors are the type and nature of the fuel, pressure and amount of fuel, geometry of the rupture, and surrounding conditions. The geometry of the structure may also be an important parameter with respect to the resistance of the passive fire protection exposed to a jet fire.

We can offer jet fire tests to document the resistance capabilities of passive fire protection materials against jet fires. We offer single tests or test series comprising of one or several jet fires, as well as jet fires in combination with varying heat flux levels, for example fires following the HC curve. Jet fires can be conducted with heat flux up to 350-400 kW/m². 

 Method (what/which methods are used to perform the service):

Standard jet fire

The objective of a standard jet fire test is to determine the resistance of passive fire protection materials and systems to jet fires. It gives an indication of how passive fire protection materials behave in a jet fire. The test methods ISO 22899-1 and OTI 95634 cover: 

- Tubulars
- Panels
- Structural steel
- Pipe- and cable penetrations

High heat flux jet fires

Our extended jet fire furnaces can be used where standard jet fires are insufficient: 

- higher temperatures (1300 – 1400 °C)
- higher heat fluxes (350 kW/m²)
- for larger test specimens (Ø ~1 m)

HC - Jet combination test series

Used for certification of different specifications, with the possibility to interpolate between tests. This enables us to test variations of the fire protection in multiple test subjects in a single horizontal furnace HC-test, and then compare this to a selection of variations subjected to a jet fire test. 

- HC fire (pool fire), horizontal furnace
- Jet fire
- Jet fire addition

Sequential jet and pool-fire test

The extended jet fire furnace can be used to simulate the exposure inside a HC fire furnace. This gives us the ability to perform a combination of jet fire directly followed by a simulated HC-fire in the same test. For example: 

- 350 kW/m² jet fire for 15 minutes + 2 hours pool fire.

Pressurized pipes, valves and end connections

We offer testing of pressurized pipes, valves and end connections according to API standards.

Mini jet-fire

This is a smaller-scale test set-up mainly developed for product development and realistic screening tests. The mini jet uses a premixed flame of air and propane to obtain similar temperature as in a standard jet fire according to ISO 22899-1. The flame temperatures are similar, but the erosion effect on the test subject is not comparable.

Measurement of print-through

Name of service (page headline, shown in promos – maximum of 70 characters incl. spaces): Measurement of print-through Lead (include SEO-words and the main benefits for your target groups. Stick to one paragraph, maximum 2-3 sentences):

Print-through is an unwanted effect when you see some of the ink from the opposite side of a paper in a magazine. It is a combination of the show-through (=effect from opacity) and the strike-through (=effect from ink penetration), both properties are closely related to the paper structure

 Purpose/Benefit:

Print-through is an often-encountered print quality problem mainly caused by ink penetration and insufficient opacity of the paper.
Non uniformity in substrate structure relates closely to print-through. Therefore, spatial variations of print-through provide a probe to the substrate’s structure.

The print through measurement can be used to:

  • Check if the print through is acceptable and stable over time
  • Benchmark to competitors
  • Monitor how new settings in the productions affect the print through
  • Check if new products are better or not
 Method (what/which methods are used to perform the service):

The measurement gives:

  • Assessment of the print quality and it's relationship with paper’s structure in an effective, reliable, fast and intuitive way, using an affordable standard flatbed scanner
  • Quantitative characteristics of print-through over a big area, both in average and in detail
  • Quantitative evaluations of print-through and its components:  show-through, strike-through, the relationships between the print-through phenomenon and the underlying physical properties and quantities

Dynamic deformation analysis

Name of service (page headline, shown in promos – maximum of 70 characters incl. spaces): Dynamic deformation analysis Lead (include SEO-words and the main benefits for your target groups. Stick to one paragraph, maximum 2-3 sentences):

ARAMIS is a non-contact optical 3D measuring system. The system analyses, computes and documents object deformations, rigid body movements and the dynamic behavior of measuring objects. This type of measurement provides deformation data over entire surfaces unlike conventional strain gauges.

 Purpose/Benefit:

Optical strain analysis is used to advantage to monitor changes in entire surfaces during, for example, load tests

Some areas of use:

For statically and dynamically loaded structures ARAMIS can determine:
- 3D coordinates and 3D offsets
- 3D speeds and accelerations
- Strain computations up to 1500°C

ARAMIS can also be used for:
- Examination of non-linear behavior
- Characterization of creep and aging processes
- Determination of Forming Limit Curves (FLC)
- Verification of FE models
- Determination of material characteristics
- Analysing the behavior of homogeneous and inhomogeneous materials
during deformation

 Method (what/which methods are used to perform the service):

ARAMIS is a non-contact 3D optical measuring system.
The system analyses, calculates and documents object deformations, rigid body movements and the dynamic behavior of the measuring objects. The system determines the 3D coordinates of discrete points over a certain period of time. The temporal resolution depends on the frequency used for image recording.

The measurement is made with two cameras on a stochastic pattern that is applied to the detail being examined. It is also possible to combine with or separately measure movements for pasted reference points in all directions and then also be displayed as "live data" directly online to the customer if not present at the measurement site.
Unlike extensometers and strain gauges, you get measured values over an entire surface that can be presented in a very illustrative way. In addition, other values such as speeds and accelerations can be deduced from the measured movements.

ARAMIS is portable and packed in transport-safe bags for measurement on site at the customer.

 Delivery (what does the client get after performed service – e.g. a report, certificate etc.):

A report describing the measurement with results according to customer requirements is delivered. In addition, raw data from the measurements can also be delivered if desired.

 Delivery time:

The measurement can usually be performed within a week from first contact and the result is normally delivered a day or two after measurement.
