適用范圍：his practice determines the compatibility of plasticizers in poly(vinyl chloride) plastics by rating the amount of plasticizer that spews due to compressional stress set up inside a 180 loop bend. Note 1 - Ingredients other than plasticizer can spew from a total formulation. The text of this practice references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of this practice. The values as stated in SI units are to be regarded as the standard. The values in brackets are given for information only. This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Note2 -There are no ISO standards covering the primary subject of this practice.
