BS EN 60754-1

BS EN 60754-1 – Tests on gases evolved during combustion of materials from cables – Determination of the halogen acid gas content.
The text of the International Standard IEC 60754-1:2011/A1:2019 was approved by CENELEC as a European Standard without any modification.
BS EN 60754 consists of the following parts, under the general title Test on gases, evolved during combustion of materials from cables:

• Part 1: Determination of the halogen acid gas content
• Part 2: Determination of acidity (by pH measurement) and conductivity
• Part 3: Measurement of low level of halogen content by ion chromatography

Part 1 of BS EN 60754 specifies the apparatus and procedure for the determination of the amount of halogen acid gas, other than hydrofluoric acid, evolved during the combustion of compounds based on halogenated polymers and compounds containing halogenated additives taken from electric or optical fibre cable constructions.

• NOTE 1 This test method is not able to determine hydrofluoric acid. A suitable method may be found in IEC 60684-2.
• NOTE 2 This test method may be used to test materials to be used in cable manufacture, but a declaration of cable performance should not be made based on such a test.
• NOTE 3 The relevant cable standard should indicate which components of the cable should be tested.
• NOTE 4 For the purposes of this standard, the term “electric cable” covers all insulated metallic conductor cables used for the conveyance of energy or signals.

The method specified in this standard is intended for the testing of individual components used in cable construction. The use of this method will enable the verification of requirements which are stated in the appropriate cable specification for individual components of cable construction.

IEC 60754-1 (BS EN 50267) was developed due to concerns expressed by cable users over the amount of acid gas which is evolved when some cable insulating, sheathing and other materials are burned, as this acid can cause extensive damage to electrical and electronic equipment not involved in the fire itself.
This standard provides a method for determining the amount of acid gases evolved by burning cable components so that limits can be agreed for cable specifications. As the test is not carried out on a complete cable test piece for a hazard assessment, the actual material volumes of the cable components should be taken into consideration.

This Standard supersedes EN 50267-1:1998 (PART), EN 50267-2-1:1998 (PART), EN 50267-2-2:1998 (PART) and EN 50267-2-3:1998 (PART).
