Specifies a method of test for the determination of the extractability of certain stabilizers of unplasticized PVC in order to verify that the extracted quantities do not exceed a certain concentration. Tubular test pieces are prewashed during a fixed time. After this they are extracted with acidified (CO2) water in three steps and the quantity of the extracted stabilizers (lead salts or organic derivates to tin) shall be determined. The analytic methods are not specified.
