In this standard, only the method for calculation of the PVC content is described, while for the determination of the chlorine content reference is made to prEN ISO 1158:1997. If the material contains or is supposed to contain chlorinated poly(vinyl chloride) (PVC-C) or chlorinated polyethylene (PE-C), an apparent PVC content is calculated.
