ISO 13229:2010 specifies a method for the determination of the viscosity number (also known as reduced viscosity) and K-value of an unplasticized poly(vinyl chloride) (PVC) resin derived from a pipe, fitting or compound. In ISO 13229:2010, only the method for isolation (or separation) of the PVC resin is detailed.
