This document specifies the digital measurement method for the determination of the anti-contamination of fabrics.
This method is applicable to woven fabrics which have or have not been given an anti-contamination to particulate matter finish. It is especially suitable for measuring apparel fabrics. It is not intended for use in fabrics that react to UV light or allow particulate matter to penetrate into the structure of the fabric. It is not applied to fabrics for personal protective equipment.
NOTE 1 Particulate matter (PM) is solid particles suspended in ambient air defined in ISO 16890‑1.
NOTE 2 In woven fabrics, particulate matter (PM) adheres to the fabric surface due to electrostatic or surface properties. In knitted and nonwoven fabrics, PM penetrates into the fabric structure, following a different mechanism. The conditions and procedures outlined in this test method are designed to ensure reproducibility and precision specifically when applied to woven fabrics.
