BS EN 60754-2:2014+A1:2020 Test on gases evolved during combustion of materials from cables - Determination of acidity (by pH measurement) and conductivity
1 Scope
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.
NOTE 1 The relevant cable standard should indicate which components of the cable should be
tested, and which method of calculation (see Clause 8) should be used in the case of dispute.
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.
