Annex A: Performance requirements (Informative)
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.
