EN 60332-3-24 is a fire test method whose test results form the basis for fire classification according to EN 45545-2 "Fire protection on railway vehicles – Part 2: Requirements for fire behaviour of materials and components".

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.
Preliminary test results can be shared when the fire test has been carried out, which is usually about 4 weeks after the test material has been delivered to RISE.

EN 45545-2

EN 61034-2 is a fire test method that generates data that is used to evaluate formed smoke density as cables burn. Test results forms a part of the basis for CE marking according to the CPR Construction Product Regulation.

In the product development context, it is important at an early stage to investigate the extent to which cables contribute to smoke development in the event of fire. Fire testing according to EN 61034-2 generates data used to determine smoke density when cables are burned.

Requirements according to the Building Products Regulation (CPR) mean that cables must be CE marked and fire classified according to the Euroclass in order to be sold as building products. In some applications, additional classification of smoke density is required. Data from tests according to EN 61034-2 form the basis for CE marking with supplementary classification s1a or s1b.

The cable to be tested is mounted in 1-meter lengths on a frame placed above a vessel containing a mixture of ethanol, methanol and water. The mixture is ignited and allowed to burn until consumed, about 40 minutes. During the test period, the smoke density formation is measured.

The fire test results are summarized in English in a test report delivered in digital format. 

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

Delivery time for accredited test report is usually 4-8 weeks.
Preliminary test results can be shared when the fire test has been carried out, which is usually about 4 weeks after the test material has been delivered to RISE.

Material consumption for testing.depends on the cable diameter, number of cable lengths needed:
40.0 < Ø → 1 pc.
20.0 < Ø ≤ 40.0 → 2 pcs.
10.0 < Ø ≤ 20.0 → 3 pcs.
 5.0 < Ø ≤ 10.0 → N₁ pcs.
where N₁ = 45 / Ø, rounded down to the nearest integer

1.0 < Ø ≤ 5.0 → the cables are distributed in bundles of 7 cable lengths in each bundle. The number of bundles, N₂, depends on the diameter of the cable and is calculated according to:
N₂ = 45/3Ø, rounded down to the nearest integer

Material consumption for non-circular cables differs slightly from the above.

Each cable length is 1 m long.

ConeTools - Development tool for predicting test results according to SBI (Single Burning Item) and RCT (Room Corner Test).

ConeTools is one of several flame spread models that RISE has developed. ConeTools allows you to predict the Euroclass for SBI and/or RCT by means of cone calorimeters test (ISO 5660-1) results at one heat flux level.

The advantages of testing according to ISO 5660-1 is less material consumption and that the test method is more cost effective than testing according to SBI or RCT. For these reasons, ConeTools is an excellent tool for the development and production control of materials and products.

When testing a product according to ISO 5660-1, a sample with the dimension 100 mm x 100 mm is subjected to a specific irradiance level. The surface of the sample is heated and starts to emit pyrolysis gases that ignite by a spark igniter. The emitted gases are collected in a hood and transported away through a ventilation system. The heat release is measured using the data on measured oxygen concentration in the emitted smoke. The smoke production is measured continually throughout the test with a laser system.

The following parameters are measured in the method: Ignition properties, Heat release rate (kW/m²), total heat release (MJ/m²), mass loss (g/s), effective net heat of combustion (MJ/kg) and smoke production rate (m²/s). Levels of toxic gases can also be measured with FTIR analysis.

A test report, in Swedish or English, is deliverd with the test results after testing.

ISO 5660-1 Reaction-to-fire tests - Heat release, smoke production and mass loss rate.

Part 1: Heat release rate (Cone calorimeter method) and smoke production rate (dynamic measurement).

The test method is used for fire technical modelling. The data from the test results can be used for modelling bigger fires. A fire sequence in the ISO 9705 – Room Corner Test and EN 13823 – SBI can for example be predicted using the ISO 5660 method.

The method is also widely used in testing at the product development stage. One can compare a variety of measurement data and thus find the variant of the product that seems most promising to proceed with in further tests.

The test method is also used for third party verification (production control).

The method is cost effective in product development and production control.

RISE is offering field sampling testing of sprinklers in accordance with Annex K of EN 12845:2015+A1:2020 and the requirements in NFPA 25

Annex K, ”Twenty‑five year inspection” of EN 12845:2015+A1:2020, ”Fixed firefighting systems – Automatic sprinkler systems – Design, installation and maintenance”, requires that a number of sprinklers should be removed and inspected no later than 25 years after their installation.

The testing indicates wheter the sprinklers in the actual system are serviceable or not.

The sprinklers are evaluated regarding the following:

a) operation;

b) operation temperature;

c) variation of K-factor;

d) spray obstacles;

e) lodgement;

f) thermal sensitivity.

Annex K of SS-EN 12845:2015+A1:2020 stipulate how many sprinklers that should be tested, but the sample should at least include 20 sprinklers. Note that RISE Fire Research only tests the actual sprinklers. Malfunction of the system may involve other parts of the system such as the pipe or the water supply. That is not taken into consideration in these tests

The tests are reported in a report in English.

ISO 5660-1 – Reaction-to-fire tests - Heat release, smoke production and mass loss rate

Part 1: Heat release rate (Cone calorimeter method) and smoke production rate (dynamic measurement)

Fire testing according to ISO 5660-1 evaluates a number of different parameters such as heat release rate, smoke production rate, ignition properties, etc. The method is used to classify materials for trains and is referred to by EN 45545-2 - Railway applications - Requirements for fire behaviour of materials and Components.

When we take the railway, we assume that the journey will be comfortable and safe. Fire safety is important in order to save lives in the event of an accident. Therefore, all materials and products installed in trains and subways must be fire tested according to EN 45545-2. The system has been developed by Technical Committee CEN/TC 256 ”Railway applications” at the request of the European Commission. The system is based on requirements from EU Directive 2016/797.  All contradictory national standards are revoked.

When testing a product according to ISO 5660-1, a sample with the dimension 100 mm x 100 mm is subjected to an irradiance level of either 25 kW/m² or 50 kW/m². The surface of the sample is heated and starts to emit pyrolysis gases that ignite by an electric spark igniter. The emitted gases are collected in a hood and transported away through a ventilation system. The heat release is measured using the data on measured oxygen concentration in the emitted smoke.

The following parameters are either measured: Time to ignition, heat release rate (kW/m²), ARHE (Average Rate of Heat Emission (kW/m²) and MARHE (Maximum Rate of Heat Emission) (kW/m²).

A test report, in Swedish or English, is delivered with the test results after testing.

RISE offers accredited testing, inspection and certification for a vast variety of fire resistant products at our sites in Borås, Sweden and Trondheim, Norway.

In the event of a fire, the fire resistance time of the constructions is the most critical component and has a direct influence on the safety. Fire-resistant products should allow the construction to retain their minimum functions during the time required to evacuate.

Fire resistance testing can be performed for a variety of constructions such as walls and glazed structures, tile floors and ceilings, beams, pillars, doors, gates, shutters and gates, ceilings, ducts, cable glands and fire dampers. Testing can be done with either vertical or horizontal load.

To prevent the spread of fire within the built environment and maintain means of escape, building legislation across the world often requires that separating elements, such as partitions, doors and glazed screens, offer known resistance to fire exposure.

RISE has two specialist fire resistance and product development test laboratories.

We offer ISO/IEC 17025 accredited fire tests to a variety of SP, national, Nordtest (NT FIRE), European (EN) and International standards (ISO, IMO). As a Notified Body of the European Commission, RISE can deliver fire testing services necessary for product conformity assessment to harmonized Product Standards and European Assessment Documents (EAD) under the EU Construction Products Directive/Regulation.

We also provide ad-hoc fire tests for the purposes of product development. If you would like to know more, feel free to contact us!

IMO 2010 FTP Code Part 5 - Test for Surface flammability (test for Surface materials and primary deck coverings)

IMO 2010 FTP Code Part 5 evaluates a material's ability to withstand a fire spreading along its surface. The method also evaluates the heat release from the material during combustion. The method is used to classify and certify materials used in marine and offshore applications.

Products and materials for maritime use is fire tested according to the International Maritime Organization (IMO) code, IMO 2010 FTP Code. The results from fire testing according to the FTP-code can be used as a basis for type approval (also called the wheel mark). Type approval is regulated in accordance with European Parliament Directive 2014/90/EU. RISE can perform the fire tests, issue the certificates and perform the production control required in order to gain the wheel mark.

The specimen is inserted in the specimen holder together with a substrate. It is vertically positioned during the test and is exposed to heat radiation from a radiation panel. The test is conducted with a pilot flame. The time is noted when the specimen is ignited as well as when the flame reaches each of the 50 mm stations along the specimen centre line. Other parameters that are notes are the time to flame out of the flame front on the center line, the burnt length and any occurrence of burning droplets.

A test report, in Swedish or English, is delivered with the test results after testing.
