    La EN 50267-2-3 prescrit la méthode d'essai et la procédure pour déterminer, par une mesure de la moyenne pondérée du pH et de la conductivité des matériaux constitutifs, l'acidité des gaz émis pendant la combustion de câbles électriques ou optiques. NOTE: Il convient que la norme du câble concerné indique quels sont les matériaux du câble qu'il convient d'essayer.
