CEN/TC 248/WG 37 - Microplastics from textile sources

This document specifies a method for measuring the collected material mass released from the outlet hose of a standard washing machine, described in ISO 6330, through the washing process.
NOTE            The washing condition of textile end products is indicated by the care labelling according to ISO 3758.
This document is applicable to textile end products (including consumer textile products, such as clothing made of fleece, shirts, trousers, blouse, etc.) and home textile end products (such as, blankets, rugs, curtains, etc.) which are composed of all fibres such as natural fibres, and man-made fibres, including mixture of the fibres that can be washed in a domestic washing machine.
This document is not applicable to fabrics and cut textile products. It does not cover the test for washing machines and detergents as well.

This document describes a method for systematically collecting material loss from fabrics under laundering test conditions to achieve comparable and accurate results. There is no direct correlation to material loss during domestic and commercial laundering. The method is designed to assess material loss of all types.
NOTE      In this document, any collected debris is assumed to be fibre fragments. For the identification of the nature/composition of this debris, the method described in ISO 4484-2 can be used.

The method describes how to determine MPs in the field of textile processing and applications, and allows their classification by particle dimension and shape as well as by type of polymer
