ISO 4333:2022

This document specifies a test method for the determination of reduction activity of textile products against specific proteins which shows antigen-antibody reaction. This document only specifies the reduction activity against those proteins on the surface of textile products. It does not specify a testing method to evaluate the allergenic reaction against human beings. Specific proteins which show antigen-antibody reaction are proteins derived from pollen, mite and other sources. Other specific proteins can be used after appropriate validation described in this document. Enzyme-linked immunosorbent assay is used to quantify the amount of those proteins in this document. This document is applicable to textile products include woven, knitted and nonwoven fabrics, fibres, yarns, braids, etc.
