SPECIFICATION FOR Methods Of Test For Gases Evolved During Combustion Of Electric Cables Part 1 : Method For Determination Of Amount Of Halogen Acid Gas Evolved During Combustion Of Polymeric Materials Taken From Cables
This standard describes a method 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 cable constructions.
This method is not recommended for use where the amount of halogen acid evolved is less than 5 mg/g of the sample taken.
The method described in this standard is intended for the type testing of individual components used in cable construction. The use of this method will enable the requirements for individual components of a cable construction to be stated in the appropriate cable specification.
