Electronic units and electronic contacts are particularlyendangered, as are free-standing or concrete enclosedsteel constructions.Test procedures1000 mg insulation material is burned in a combustion furnaceat ≥ 935 °C with pre-defined air supply for over 30 minutes. Bymeans of two gas washing containers, held in the airflow theconductivity and the pH-value are measured. Like that evensmall quantities of halogen containing substances can be detectedand proven.The test is considered to be passed whenthe ph-value > 4,3the conductivity < 10 µS/mmTest standardsIEC 60754-2; BS EN 50267-2-2; VDE 0482-267-2-2IEC 60754-2, EN 50267-2-2OfenCombustion furnacesynth.
