EN 50267-2-3 Acidity test– Test requirements
The samples should be stored at a temperature of (23 ± 2) ℃ and a relative humidity of (50 ± 5)% for at least 16 hours
EN 50267-2-3 Acidity test– Scope
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 materials.
NOTE The relevant cable standard should indicate which materials from the cable should be tested.
