Electric cables - Extended application of test results for reaction to fire
N CLC/TS 50576
Annotation
This Technical Specification gives the procedure and rules for extended application of results of tests carried out according to the test methods described in EN 50399, EN 60332-1-2 and EN 61034-2.
The EXAP rules described apply to EN 50399 test results used for classification in classes B2ca,Cca and Dca, additional smoke production classes s1, s2 and s3 and flaming droplets/particles, to EN 60332-1-2 test results used for classification in classes B2ca,Cca, Dca and Eca and to EN 61034-2 test results used for classification in classes s1a and s1b.
Cables of diameter 5,0 mm and less should be tested as bundles according to EN 50399. Bundled cables are not included in the EXAP rules applying to EN 50399 test results.
The rules apply to circular and non-circular cables provided that they fall within the scope of the relevant test method.
A specific EXAP rule has been developed for the most common generic power cable families and optical fibre cables.
A general EXAP rule has been developed for any power cable families. The general EXAP rule is not applicable to communication or optical fibre cables.
NOTE 1 Multicore power cables with more than 5 cores are sometimes referred to as control cables with a rated voltage but for the purposes of this Technical Specification are considered as power cables.
The general EXAP rule may be applied in the case of hybrid cables provided that the conditions of 6.1 are fulfilled.
The use of the specific EXAP rule gives benefit in the lower number of cables to be tested for a range of cable constructions (product family).
