รายละเอียดเอกสาร

This document provides a description of the test method and threshold criteria for determining if a product will disintegrate sufficiently to be compatible with wastewater transport systems. The document is designed to be used in conjunction with IWSFG PAS1: 2020 Criteria for Recognition as a Flushable Product and IWSFG PAS2: 2020 Terms and Definitions for Determination of Flushability. The purpose of this test is to assess the disintegration performance of a material when it is subjected to hydraulic forces typically found in continuous flow conditions in small diameter (8 inch/200 mm) wastewater transport systems, after a product is flushed: i.e., ratio of forces equivalent to a Reynolds number of 20,000. This Specification applies to all products that: 1. A manufacturer may wish to identify as being flushable; or 2. Because of the location of their use in the toilet or bathroom or likely contamination by human excreta are likely to be flushed through a toilet into a drain line and wastewater transport and treatment system. Dry toilet paper is out of scope of this document.
