1 Scope 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 B2 ca ,C ca and D ca , additional smoke production classes s1, s2 and s3 and flaming droplets/particles, to EN 60332‑1‑2 test results used for classification in classes B2 ca ,C ca, D ca and E ca 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 .
