International Standards and Conformity Assessment for all electrical, electronic and related technologies



Reference HD 405.1 S1:1983/A1:1992
Title Tests on electric cables under fire conditions - Part 1: Test on a single vertical insulated wire or cable
Project Number 237
Abstract/Scope This standard specifies a method of test on a single vertical insulated wire or cable and the requirement for compliance. Notes 1. - Since the use of insulated wire or cable that complies with the requirement is not sufficient by itself to prevent propagation of fire undler all conditidons of installation, it is recommended that wherever the risk of propagation is high, for example in long vertical runs dof bunches of cables, special installation precautions should also be taken. It cannot be assumed that because the sample of cable complies with the performance required in this standard that a bunch of cables will behave in a similar manner. 2. - The method specified is not suitable for the testing of some small wires due to the melting of the conductors during the time of application of the flame.

Normative reference (6)  

(1) Date of ratification (dor) date when the Technical Board notes the approval of an EN (and HD for CENELEC), from which time the standard may be said to be approved

(2) Date of availability (dav) date when the definitive text in the official language versions of an approved CEN/CENELEC publication is distributed by the Central Secretariat

(3) Date of announcement (doa) latest date by which the existence of an EN (and HD for CENELEC), a TS or a CWA has to be announced at national level

(4) Date of publication (dop) latest date by which an EN has to be implemented at national level by publication of an identical national standard or by endorsement

(5) Date of withdrawal (dow) latest date by which national standards conflicting with an EN (and HD for CENELEC) have to be withdrawn
