适用范围：This International Standard specifies a method for the determination of the viscosity number (also known asreduced viscosity) and K-value of an unplasticized poly(vinyl chloride) (PVC) resin derived from a pipe, fittingor compound.In this International Standard, only the method for isolation (or separation) of the PVC resin is detailed, whilethe determination of the viscosity number is given in ISO 1628-2.The presence of other additives or polymers can invalidate this method (see Clause 3).
