Fatigue testing is carried out with a cyclic load, until breakage occurs. The purpose is to determine the fatigue life and strength of a material or component. We perform both standardized and specialized fatigue testing on materials and components, for both machinery and products for construction and infrastrucrure.

Fatigue test results are an important basis for assessing life expectancy and strength of materials, components or structures under cyclic load, or to ensure that the necessary safety criteria are met.

The question may vary with application. In low cycle fatigue (LCF), high loads are of interest, around the yields stress limit of the material, while in high cycle fatigue (HCF) lower loads with a large number of cycles are looked at, up to the so-called fatigue limit. In this area, so-called SN curves can be plotted to examine the relationship between load amplitude and service life.  The test can be carried out in different ways, e.g. load-controlled (controlled force) or elongation-displacement controlled (controlled elongation/displacement).

In our laboratory in Borås, we can perform tests on everything from small test bars to complete components with a size over 10 meters, and with loads up to 20 MN (2000 metric tons). To determine fatigue limits (high cycle numbers) of materials that are not frequency dependent, our resonance machines allow load frequencies around 100 Hz. We can also use variable amplitude (spectrum fatigue), or simulate custom load spectra specific to the application.

Specialized test setups with multi-axial loads can be built up on test floors with attachment points, where load are applied with hydraulic cylinders.

Test assignments are often complemented with various add-on services, such as:

• Testing at elevated temperatures,
• Prediction of life expectancy, load analysis, reliability and uncertainty assessment,
• Spectrum fatigue (variable-amplitude loads),
• Fracture mechanical analysis,
• Tensile test with advanced measuring techniques, such as acoustic emission (AE) and digital image correlation (DIC) methods,
• Development of material models for FEM analysis,
• Validation and verification (V&V) for quality assurance of simulation models.

Fatigue testing is carried out in our accredited laboratory in Borås. We are accredited for methods ASTM E466, ASTM E606, ECE R55.

The work include both accredited and non-accredited testing methods. The scope of accreditation is available upon request – please feel free to contact us for more information.

Fatigue test results may be in the form of Wöhler diagrams (S-N curves) showing load amplitude against number of cycles, determination of a fatigue limit or verification of service life. When an applicable standard exists, results may be delivered accordingly.

Fatigue testing takes time, as a number of tests must be cyclically loaded over a long period of time. The delivery time is mainly affected by the number of tests, the number of cycles required for each test and the frequency that can be used in the test.

Test specimens can either be provided by the customer, or manufactured in our workshop from customer material samples. Components are normally provided by the customer.

We measure thermal conductivity (i.e. heat conduction) using the Transient Plane Source (TPS) method according to ISO 22997-2 for which we are an accredited laboratory. The TPS method can be used to measure the thermal conductivity, diffusivity  and the specific heat capacity on solids, liquids, gels and powder in temperatures between -50 °C and 600 °C.

We can also measure thermal conductivity using Transient Line Source (TLS) which is a fast and simple method with a limited temperature range between 0 °C and 100 °C.

Determination of thermal conductivity (λ) och diffusivity (α) and volumetric specific heat capacity (ρc_p).

TPS

RISE is accredited for measurement of thermal conductivity according to ISO-22007-2, “Determination of thermal conductivity and thermal diffusivity - Part 2: Transient plane heat source (hot disc) method”. The method is specified for polymeric materials, but it is possible to measure on most solids and highly viscous materials as well as powders.

TLS

Transient Line Source method (TLS) according to ASTM D5334-14 is used for determination of thermal conductivity, which is simpler and faster than TPS when measuring. The temperature range for this measurement is between 0 °C and 100 °C.

After the measurement has been performed, a report is delivered that describes the tests, conditions, the procedures and results.

The TPS measurements takes up to 1 week from the time the samples have arrived at RISE. Completed report is delivered within 3 weeks of the measurements being performed, a draft of the report can be delivered earlier.

The TLS measurements can often be made the day after the sample arrives at RISE. Completed report is delivered within 2 weeks of the measurements being performed.

The samples must be prepared before taking any measurements. The samples must be manufactured or processed so that they meet the requirements that the sensors place on the sample geometry. We can also process the samples on RISE. We always condition the samples for 24 hours before the measurements are performed, unless otherwise requested.

This method describes the testing of flame spread properties with a small defined flame. The test is performed on flexible materials such as textiles, coated textiles and leather.

The method is primarily used for materials for protective clothing.

The purpose of this method is to evaluate the fire properties of materials.

Materials that are included in protective clothing and work wear that come into contact with fire / flames must not ignite and burn. The method intends to evaluate the flame spread properties of the tested material. Thus, unsuitable materials can be identified.

Ignition is carried out for 10 seconds with a small gas flame against the surface or bottom edge of the material.

The flame spread properties of the material are recorded, such as burning time, glowing time, burning or molten debris, hole formation and if flames reach the edges of the test specimen.

Testing is often performed both before and after washing.

Several product standards used for CE labelling refers to this method i.e. SS-EN ISO 14116.

One report in Swedish or English with obtained results.

Normal delivery time is 5-10 working days. A more accurate delivery time is stated in the order confirmation which is sent after received order and test material.

RISE offers in vitro analysis to study interactions between the small intestine and substances or microbiota.

We offer the in vitro modell EpiIntestinal to study the small intestine:

EpiIntestinal (MatTek Corporations) is a in vitro model based on human primary cells from the small intestinel The model simulates a human small intestine which one can use to study uptake rate, uptake mechanisms, inflammatory responses, gene expression, cytokine production, toxcicity and interactions with microbiota and more. When studying bioavailability of potential drug substances or effect of probiotica this is a prefered model to choose to be able to screen many candidates fast to be able to choose the best ones earlier in the development phase. The model is more translatable to human situation and correlates better with human clinical absorption data than the older Caco2 model. We are happy to assist you when you deside upon parameters, study design and read outs. Everything can be adjusted according to your needs. 

By screening substances in vitro before going in vivo you will save both money and research animals by finding the best candidates in an earlier part of the development. By choosing the EpiIntestinal model could help translating the in vitro results into real utake in humans, since data from rodents not always are translatable to humans. It is also posible to investigate interactions with microbiota specific for humans. 

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 either the supernatant or the cells depending on parameters of interest for the customer. If the study aim to detect anti inflammatory effect in teh small intestine we can both look at cytokine secretion or gene expeession. 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 parameters of interest for the customer.

The customer is provided with a report including values for parameters of interest for their substances and quality assurance 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 befor test start.

Tests on electric and optical fibre cables under fire conditions – Part 1-2: Test for vertical flame propagation for a single insulated wire or cable – Procedure for 1 kW pre-mixed flame.

Fire test according to EN 60332-1-2 evaluates a cable's fire properties in terms of flame spread. The main area of application is to create a basis for classification in fire classes B1ca, B2ca, Cca, Dca and Eca according to the European system for Euro classes.

In the EU, construction products must be CE marked according to the Construction Products Regulation (CPR).
Cables covered by the product standard EN 50575 are affected by CPR, which is why CE marking is a requirement for the cable to be sold within the EU.
The basis for the CE marking is fire classification according to EN 13501-6. This includes fire testing according to method EN 60332-1-2. The method forms the basis for the fire classes B1_ca, B2_ca, C_ca, D_ca and E_ca .

In addition to the benefits of CE marking, the method also provides important information about the cable's fire properties and is therefore often used in product development contexts and process optimization.

The specimen shall be straightened and secured in two horizontal supports with an appropriate size of copper wire in a vertical position. A burner shall be positioned so that the inner blue cone of the flame hits the surface of the specimen at a distance of (475 ± 5) mm from the lower edge of the upper horizontal support, while the burner is at an angle of 45 ° ± 2 ° to the vertical axis of the specimen. Flame application time depends on cable diameter.

• Power cables - insulated conductors and cables for use in e.g. electricity supply.
• Control and communication cables - wires, symmetrical cables and coaxial cables with metal conductors for use in eg. telecommunications, data transmission, radio frequency, video communication and signal and control equipment.
• Optical fiber cables - for us in e.g. in telecommunications, data transmission, radio frequency, video communication and signal and control Equipment.

The fire test results are reported in an English test report.

RISE holds both accreditation and notification regarding this test method why the test report is valid as a part of the CE marking documentation.

It is interesting and instructive to watch fire testing and therefore we welcome our clients to visit us at the test occasions.

The test sample shall be a piece of single insulated conductor or cable, 600 ± 25 mm long.

Up to three test samples is used to complete the test.

Testing according to EN IEC 60332-3-24 examines the vertical flame spread when the cable is fire tested. Test results form a basis for fire classification according to EN 45545-2 "Railway vehicle fire safety - Requirements for fire safety of materials and components".

Series EN IEC 60332-3-21, EN IEC EN IEC 60332-3-21, EN IEC 60332-3-22, EN IEC 60332-3-23, EN IEC 60332-3-24 and EN IEC 60332-3-25 describe standardized test methods that previously formed basis for fire categories A / FR, A, B, C and D according to SS 424 14 75 "Cables - Testing of fire properties ".

SS 424 14 75 now refers to the European method for fire classification of cables, EN 13501-6.

The fire test lasts for 60 minutes. During the first 40/20¹⁾ minutes, the cable is exposed to a burner of 20.5 kW. After the burner is extinguished, another 20/40¹⁾ minutes may elapse before any remaining fire/glow is extinguished and the extent of fire-damaged length of the cable is measured. Before testing, the cable is mounted in 3.5-meter lengths on a test ladder. Depending on the cross-sectional area of ​​the conductor, the cable lengths are mounted on the test ladder with or without spaces.
¹⁾ Exposure time 40 min refers to the methods EN IEC 60332-3-21, -22 and -23 while the exposure time 20 min refers to the methods EN IEC 60332-3-24 and -25.

The cable lengths are evenly distributed on the test ladder. During the fire test, the ladder with the cable lengthss are placed vertically against a wall in a combustion chamber. In front of the ladder the burner is placed at a distance of 7.5 cm from the cable lengths.

The fire test results are summarized in English in a test report delivered in digital format.
Video of the testing can also be obtained.

It is interesting and instructive to watch fire testing and therefore we welcome our clients to visit us at the test occasions.

Delivery time for accredited test report is usually 4-8 weeks.
