1 Scope
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.
