BS EN 1905:1999 Plastics piping systems. Unplasticized poly(vinyl chloride) (PVC-U) pipes, fittings and material. Method for assessment of the PVC content based on total chlorine content
This standard specifies a method for assessing the poly(vinyl chloride) (PVC) content in reprocessable and recyclable unplasticized (PVC-U) materials or materials derived from PVC-U products.
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.
