Investigation of products according to EN 45545-2 - Railway applications - Requirements for fire behaviour of materials and components.
Subclause 4.3 - Grouping rules.

Table 2 of EN 45545-2 lists the most common products for trains. Table 3 is for products that are not listed in Table 2 but are of a simpler design with few constituent materials or components. For more complex products such as electronic equipment consisting of a variety of materials and components, there are no clear requirements in EN 45545-2. For these products, an investigation is required to find out what needs to be tested in order for the product as a whole to be classifiable. The investigation follows the flow chart for grouping rules found in subclause 4.3 of the standard.

Each of the product's constituent materials/components must be handled in the flow chart. There are some rules to consider when it comes to the exposed surface, weight and and also distance.

A material or component weighing up to 10 g which is not in direct contact with any other material or component non-approved according to EN 45545-2 need not to be tested or grouped.

• A group is defined as materials/components that are within 200 mm in vertical direction and 20 mm in horizontal direction of each other
• Up to 100 g (interior) or 400 g (exterior) of combustibles are allowed per group with no requirements
• Up to 500 g (interior) or 2000 g (exterior) of combustibles per group are allowed which are approved according to requirement set R24 (EN ISO 4589-2)
• Combustibles in groups weighing more than 500 g (interior) or 2000 g (exterior) have to fulfil requirement set R22 (interior) eller R23 (exterior) (EN ISO 4589-2, EN ISO 5659-2, NF X 70-100-1 & -2 or EN 17084)

Above rules apply to groups but also to individual materials/components that have an exposed surface area of ​​less than 0.2 m².

An exposed surface area larger than 0.2 m² means fulfilment according to requirement set R1 (interior) or R7 (exterior) (ISO 5658-2, ISO 5660-1, EN ISO 5659-2+toxicity (EN 45545-2, annex C or EN 17084).

An alternative to the above investigation procedure is that the product meets any of the requirements as set out in 4.2 h in EN 45545-2. Here, among other options, is the opportunity to place the product in a technical cabinet that is protected by some kind of extinguishing system. Such a solution can mean that the product is approved to install without testing.

An investigation means that the product is weighed and measured and then taken apart to the greatest extent possible. The constituent materials/components are weighed and, if relevant, the distance between these materials/components is measures as well as the exposed surface area.

A report describes the conditions for approval of the product and has a summary, at the end, of what is needed in terms of testing, if any, for a possible classification of the product. The product and all its constituent materials/components are photographed on a scale where the weight is visible. These photos are included in the report together with a table listing the constituent materials/components and the applicable requirements according to EN 45545-2.

An investigation report, in Swedish or English, is delivered.

Thermal runaway is a stage of rapid self-heating of the battery cell that in the worst case can result in a fire or explosion. Abuse testing of batteries causes thermal runaway and is tested for product development purposes or product approvals in an open or closed reactor.

Our unique pressure vessel offers a cost efficient and quick method to evaluate temperatures, pressure, flow, particles, elemental analysis, total hydrocarbons (THC) and gases released by batteries. It allows battery cells and battery assemblies to be safely tested to gather information needed to assess thermal propagation.

If requested, our vessel can be utilized to obtain UL 9540a approval for your product. This method was designed by UL to evaluate the fire characteristics of a battery energy storage system that undergoes thermal runaway. More information about this test standard can be found on UL's website.

The method for determining the total volume of battery gas produced and the composition of those gases. Maximum pressure in the vessel is recorded as well as temperature and voltage for the tested object. 

The sample is placed inside the reactor and then abused until it goes into thermal runaway. Typically, a heating pad or nail penetration device is used. 

Gas volume

In the closed reactor the maximum pressure and temperature can be used to measure the total volume of gas released by the battery.

For the open reactor a calibrated flow tube with a differential pressure meter and thermocouples are used to calculate the total volume and the mass flow of gas produced by the battery. 

Gas composition

The gas samples are analyzed by FID to measure the THC and Gas Chromatography (GC) to analyze O₂, CO, CO₂, H₂, CH₄, C₂H₄, C₂H₆, C₃H₆, C₃H₈.

Particle size distribution

Particle size distribution can be used for both open and closed reactor by differential low-pressure impactor (DLPI) and measure particles in the range of 0.03 to 15 µm. 

For the open reactor DLPI is attached after the flow tube and the particles in the flow are caught. For the closed reactor ashes are collected from the reactor after the test and blown through a pipe with a constant flow to simulate a ventilation of a battery. The DLPI is attached to the pipe to analyze the particles.

Elemental analysis

The particles from the DLPI and ashes can be analyzed with X-ray fluorescence (XRF) and Induction coupled plasma for elemental analysis and ion chromatography (IC) can be used to analyze the total fluoride content in particles. 

If you have any questions or want more information about the battery abuse tests in a reactor, please contact us by reaching out to our contact person below or fill in the application.

Current fire danger maps (SMHI)

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.

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.
