GB/T 17650.2 Test on gases evolved during combustion of materials from cables Part 2: Determination of degree of acidity of gases by measuring pH and conductivity

GB/T 17650.2 Acidity of gases by measuring pH and conductivity – Scope
Part 2 of this standard specifies the method for measuring the acidity of gases released from the components of cables or optical cables during combustion.

Note:
1. The relevant cable or optical cable standard should state the composition of the cable or optical cable to be tested and the calculation method to be used in case of dispute (see Chapter 8).
2. The term "cable" in this standard refers to all insulated metal conductor cables that transmit the most energy and signals.
