RISE regularly conducts fire tests on plastic fuel tanks for vehicles. The fire tests are carried out in our large fire test hall in accordance with UN Regulation 34 annex 5, clause 5. 

In most cases, each vehicle model has a uniquely designed fuel tank that must meet the requirements of the method. The current tank must, according to the method, be installed in a test rig that simulates a real installation. In practice, this usually means that the tank is installed in the current vehicle. Components, such as heat shields, plastic shields, etc., that protect the tank or affect the the cource of the flames must as far as possible be installed before each fire test. For practical reasons, one cannot normally use an entire vehicle. When tanks for passenger cars are tested, a half BIW (Body In White) chassis is normally used, i.e. no windows, seats, interior etc. The chassis should normally be used for at least three tests, which means that any combustible parts must be replaced between tests.

The tank is exposed to the fire according to a special procedure for 2 minutes. The tank shall be half filled with fuel and the requirement is that there shall be no leakage of liquid fuel from the tank.

Fire tests are carried out in our large fire test  hall in accordance with UN Regulation 34 annex 5, chapter 5. RISE is accredited for the method and has been designated by the Swedish Transport Agency (TS) as the Technical Service for testing plastic fuel tanks. 

RISE is also approved to carry out initial assessment and monitoring of manufacturers' quality management systems in the area of type approval.

Performed testing with associated report can be used as a basis for certification of the plastic fuel tank. Often, certification organizations (TÜV, VCA, RDW, TS etc.) require tests to be witnessed by the relevant organization.

In order to carry out the fire tests, a chassis including relevant components as well as relevant information about the fuel system and how it should be mounted is required. Please enter into a dialogue with one of our contact persons. We also recommend starting a dialogue with a certifying organization at an early stage.

RISE can offer testing of sprinkler system components and fire performance testing of sprinkler systems in accordance with relevant ISO- and EN-standards.

We can also offer consultation with regards to hazard classification and testing to determine the commodity classification of goods.

The commodity class is one of the parameters used in sprinkler system design.

Petrographic analysis of aggregates for use in concrete, roads, and asphalt.

The purpose of petrographic analysis of aggregates is to ensure that rock, natural gravel, and recycled materials have appropriate properties for inclusion as a subcomponent in various end products. We issue appropriate test reports with statements for road, railway, asphalt, construction, and concrete purposes according to, among others, EN 13043, EN 13242, TDOK 2015:0759/EN 13450, and EN 12620 / SS 137003.

The right subcomponents for the end products will ensure long durability, good ability to withstand external influences and savings for society in infrastructure projects such as roads, bridges, dam structures and substructures for railway traffic.

See also our services within Alkali Silica Reactions (ASR) and Testing, inspection/audit, and certification of aggregates.

We are accredited for all the mentioned methods for petrographic analysis. Methods used for the evaluation of aggregate materials are RILEM AAR-1.1 (microscopic method), often in combination with SS-EN 932-3 (macroscopic/ocular method).

For road structures and unbound layers in relation to stability, Method TDOK 2014:0144 - method C (thin section analysis) is used for the evaluation of free mica content.

Sample preparation and petrographic analysis is carried out in our laboratory located in Borås. Test reports according to the method are obtained.

RISE offer an in vitro model to study pro, anti and inflammatory attributes of subtances in the signal path of NF-kB.

Inflammatory responses in humens are mainly associated with the NF-kB signaling pathway. This response is triggered by substances from bacteria and virus but also by other types of stress like UV light or chemical substances. When a substance trigger a NF-kB response an inflamation is initiated in the body.

Sometimes when we are sick and have a high activation of NF-kB we want to ease the symptoms related to inflammation (eg. fever) by taking anti inflammatory pharmaceuticals (eg acetyl slicylic acid or paracetamol).

To introduce novel substances or food sources in our diet or local environment it is important to know if these can cause an infammation in persons exposed to them or if they can have the posibility to lower the inflammatory response.

We offer an simple model giving the posibility to study many samples at the same time in an in vitro model. This model can determine if a substance is pro, anti or neutral regarding an inflammatory respons in the NF-kB signaling pathway. 

By evaluating substances in vitro before going in vivo, both reseach animals and money can be saved by choosing the best candidate in an earlier stage of the development.

The model is based on GloResponse™ NF-κB-RE-luc2P HEK293. This is a transformed cell line expressing an enzyme (luciferace) under the NF-kB-promotor. When the NF-kB gene is activated, the enzyme will be expressed. One measures the activation by adding substrate (luciferin) for the enzyme and the end point is luminiscence.

If one is interested in inhibition of this signal patwhay one stimulates the cells with TNF-a to get an enhanced background level before trying to lower this activation with substances of choise. To eliminate false positive, were the effect seen is due to an toxic response leading to cell death instead of lowering readout, this version of the method is coupled with an toxcicity assay as controlls. 

The customer will get a report containing parameters of choice and qulity assurance data of the toxcicity of the substances.

It ususally takes two weeks to start up cells from cryopreservation. More over time for the specific test will add on making the total time of 4 weeks from acceptance of tender. Contact us for a more specific time frame.

Weekends or national holidays will affect the delivery time. 

Information regarding test subtstance need to be discussed before start of cultivation of the model systems. The test substances need to arrive one week before test start.

A common fire cause during storage of porous organic materials is autoignition. The reason is self-heating, which is triggered by microbial activity, chemical oxidation or physical processes from moisture migration. The most common small-scale method is a so-called wire basket test that evaluates self-heating from chemical oxidation.

Wire basket tests are technically simple but time-consuming methods used to investigate self-heating and autoignition of different materials. Basket tests are available in several different versions, both analytical methods for research purposes and standardised methods for transport of dangerous goods, for example. The version needed/required depends on how and where the result will to be used. See "Method" for more information.

The tests generate data that can be used as a basis for risk analysis, research or for transport of dangerous goods (self-heating materials).

In a wire basket test, the material to be examined is placed inside a wire mesh cube, which is located inside an oven at a fixed elevated temperature. The temperature is then measured in the oven and at the centre of the sample over time.

Three different temperature patterns can usually be observed:

• Subcritical. The temperature in the centre increases slowly towards the oven temperature, but never exceeds it.
• Critical. The temperature in the centre of the sample increases only a little above the oven temperature, reaches a plateau, and then decreases.
• Supercritical. The temperature in the centre increases, sometimes reaches a plateau, before rising rapidly above oven temperature. Self-heating has occurred and there is a risk for autoignition.

The procedure for testing varies somewhat depending on the version/standard of wire basket test used. If the purpose is analysis/research, repeated attempts are usually carried out with elevated oven temperatures until the supercritical temperature is found, the procedure is then repeated with different volumes on the wire basket. For example, the results can be used to calculate critical temperatures in larger scale using Frank-Kamenetskii theory. This can be used to assess critical storage size or critical storage time.

If the purpose of the test is standardised testing according to the UN N4 test, the occurrence of self-heating (temperature increase in the centre of the material > 60 °C above oven temperature) is examined at a specified oven temperature and test volume.

A test report, in Swedish or English, is delivered with the test results after testing. Measurement files can also be included.

SP Method 2369 - Protection System for Storage of Inflammable Goods in Retail Environments - Fire Safety Cabinets

This method evaluates the construction of fire safety cabinets designed for storing flammable goods in retail environments and their ability to protect its contents from internal and external fires. The general function of this cabinet is to control and extinguish a large internal fire, but also that an external fire does not spread to its contents.

Fire safety cabinet’s that fulfill SPCR 102 requirements protects its contents, and their surroundings, up to 30 min in realistic early stage fire scenario’s. In this period, it is crucial that flammable goods do not get involved, or spread the fire, and cause control of the situation to be lost. An example of a fire safety cabinet preventing the total loss of a store is seen in the photograph at the bottom of this page. This cabinet successfully protected the flammable goods, and the retail facility.

SP Method 2369 may be divided into two types of tests, general tests and fire tests. The general tests are designed to evaluate the following requirements (note that the text refers to section numbers in SP Method 2369):

• General construction (req. 6.1)
• Wall construction (req. 6.1)
• Mechanical integrity (req. 6.1 / test 7.2)
• Hinges (req. 6.1)
• Door closer (req. 6.1 / test 7.3)
• Tightness and volume of the spill tray (6.1 / 7.4)
• Equipment (req. 6.1).

Two fire tests are performed:

• Internal fire exposure (req. 6.2 / test 7.5)
• External fire exposure (req. 6.3 / test 7.6)

All tests are performed at RISE in Borås, Sweden.

After testing, a test report is delivered with the results which may be the basis for product approval (P-mark) according to SPCR 102.

A total of 3 tests samples are needed.

SP Method 2369 version 6

RISE offers an in vitro method to study the uptake of substances that are to be oraly administred.

We offer two different modells to study uptake in the small intestine:

- Caco2 is the classical in viitro method used to study uptake in small intestine. The modell uses cancer cells originating in the colon. These cells will spontaneously differentiate to someting similar to the small intestine. The membrane integrity are still similar to that of the colon.

- EpiIntestinal is a mor modern method using human primary cells originating from the small intestin. This modell correlate better with human clinical data than Caco2.

We will help you choose the modell fit for your experiments. Study design can be adjusted to fit your whishes regarding concentrations, controlls and exposure time. 

Evaluating substances in vitro befor moving into in vivo will save both research animals and money by eliminate unfit candidates at an earlier time in the development. Testing on EpiIntestinal might also help translate your data to expected uptake in human since the animals usually tested for uptake befor human is rodents. EpiIntestinal correlates better with the human clinical data than the rodents in some aspects.

When ordered, the coosen model system are put into cultivation for that specific customer project making it important to have all aspects of the study design in place before cultivation starts. When the models are ready, 4 weeks later, they are usually exposed with the test substances for two hours. Samples are then taken from  the original solution, lumen and blod side if the models and presented to the customers as Papp values. 

If the substance arent to be found in the lumen or blood side of the modell we will suggest adding on a analysis of the membrane to see if it is associated to the cells or the membrane or if it has been metabolized. 

To ensure that the membrane integrity is high, permeability is tested on each replicate with lucifer yellow as a marker or with TEER. This information will be included in the report together with the permeability of the substances (Papp values).

The customer will get a report including permeability (Papp) for the specific substances and quality controll of the membranes. 

1,5 month after accepted tender. Since cultivation of the modelsystems takes 4 weeks we recommend you to discuss study design with one of the contact persons before putting an order ensuring that the right amount of replicatates are used. Exposure time also affects delivery time. Weekends or national holidays will affect the delivery time.

Information regarding test subtstance need to be discussed before start of cultivation of the model systems. The test substances need to arrive one week before test start.

Smoking in sofas and armchairs can be a cause of fires. The ignitability of furnitures is an important feature to consider when evaluating fire risks. These standards specify test methods to assess the ignitability of material combinations such as cover and fillings intended to be used for upholstered seating, when subjected to smoldering cigarette

The methods aim to evaluate the ignitability of material combinations such as cover and fillings intended to be used for upholstered seating.

The ability of upholstered seating to be easy ignited provides a basis for assessing its suitability for use in certain environments. Different requirements may apply in different types of environments. These methods are useful for evaluating ignitability of material combinations in upholstered furniture, both for home and public environments.

Method SS-EN 1021-1 and ISO 8191-1. An assembly is arranged to represent in stylized form a junction between a seat and back. The ignitability of an assembly is determined by applying smoldering cigarettes in the junction. The progress of combustion is observed and recorded of any evidence for progressive smoldering or flaming in the interior and/or cover within 1 hour. The extent of the damage must also not reach the edges or through the test body.

Method SS-EN 1021-2 and ISO 8191-2. An assembly is arranged to represent in stylized form a junction between a seat and back. The ignitability of an assembly is determined by applying a gas, match flame equivalent in the junction. The flame is removed after 15 s for method SS-EN 1021-2 and 20 s for method ISO 8191-2. The progress of combustion is observed and recorded of any evidence for progressive smoldering after 1 hour or flaming that continues for more than 120 s after removal of the burner tube. The extent of the damage must also not reach the edges or through the test body.

All fabrics that have been treated chemically with flameretardant shall be soaked and dried prior to testing in accordance with the procedure described in Appendix D, this applies to tests methods SS-EN 1021-1 and SS-EN 1021-2
