Common test methods for cables under fire conditions — Tests on gases evolved during combustion of materials from cables — Part 2-3: Procedures — Determination of degree of acidity of gases for cables by determination of the weighted average of pH and ...
EN 50267-2-3 specifies the test method and procedure for the determination of the degree of acidity of gases evolved during the combustion of electric or optical cables by determination of the weighted average of pH and conductivity of the constituent maetrials. Note: the relevant cable standard should indicate which materials from the cable should be tested.
