Fire testing of cables according to EN 60332-1-2
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.
Purpose
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 B1ca, B2ca, Cca, Dca and Eca .
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.
Method
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.
Deliveries
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.
