IEC 754-2 Test for Gases Released During Combustion of Materials from Cables

EUROLAB laboratory provides testing and compliance services within the scope of IEC 754-2 standard. This standard specifies the apparatus and procedure for determining the potential corrosiveness of gases released during the combustion of materials from electrical or fiber optic cable structures by measuring the acidity (pH) and conductivity of a liquid solution.

These are the gases produced during combustion. The general method specified in this standard is designed for testing individual components used in a cable construction. Formulas are given for calculating a weighted value for a material combination in a specified cable.

Use of this method will provide verification of the relevant requirements for individual components or associated components of a cable structure as specified in the appropriate cable specification. Where it is necessary to demonstrate compliance with a specified performance requirement for quality control purposes only, a simplified method for testing individual components is included.

Technical changes are as follows:

• Improved definition of gas containment safety requirements;
• Introducing the guide for the preparation of test specimens for more even combustion;
• Better expression of tolerance and precision;
• Clarification of conductivity and acidity functions;
• Improved description of the heating procedure;
• Greater precision in definition of test temperature for determination of pH value and conductivity;
• Correction of formulas for calculating test results.
