Test on gases evolved during combustion of materials from cables - Part 2: Determination of acidity (by pH measurement) and conductivity (IEC 60754-2:2011); German version EN 60754-2:2014
Prüfung der bei der Verbrennung der Werkstoffe von Kabeln und isolierten Leitungen entstehenden Gase - Teil 2: Bestimmung der Azidität (durch Messung des pH-Wertes) und Leitfähigkeit (IEC 60754-2:2011); Deutsche Fassung EN 60754-2:2014
Overview
This part of IEC 60754 specifies the apparatus and procedure for the determination of the potential corrosivity of gases evolved during the combustion of materials taken from electric or optical fibre cable constructions by measuring the acidity (pH) and conductivity of an aqueous solution resulting from the gases evolved during the combustion. The general method specified in this standard is intended for the testing of individual components used in a cable construction. Formulae are given for the calculation of a weighted value for a combination of materials found in a specified cable. The use of this method will enable the verification of relevant requirements for either individual components or combined components of a cable construction stated in the appropriate cable specification. A simplified method is included for the testing of individual components where it is required only to demonstrate compliance with a stated performance requirement for quality control purposes. The responsible committee is Subcommittee DKE/UK 411.2 "Isolierte Starkstromleitungen" ("Insulated cables, wires and flexible cords for power installation") of the DKE (German Commission for Electrical, Electronic and Information Technologies) at DIN and VDE.
