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 heating (combustion) procedure of this part of IEC 60754 is the same as in IEC 60754-3.
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.dition 2.1 2019-11 CONSOLIDATED VERSION VERSION CONSOLIDéE colour inside GROUP SAFETY PUBLICATION PUBLICATION GROUPéE DE SéCURITé Test on gases evolved during combustion of materials from cables – Part 2: Determination of acidity (by pH measurement) and conductivity Essai sur les gaz émis lors de la combustion des matériaux prélevés sur cables – Partie 2: Détermination de la conductivité et de l‘a(chǎn)cidité (par mesure du pH) IEC 60754-2:2011-11+AMD1:20
