Specific protein testing for plastics and other non-porous surfaces ISO/PWI 25658

Scope

This document specifies methods for measuring reduction activity of plastics and other nonporous products against specific proteins which show antigen-antibody reaction. This document only specifies the reduction activity against those proteins on the surface of plastics and other non-porous 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. Enzyme-linked immunosorbent assay (ELISA) is used to quantify the amount of those proteins. This method is applicable to non-porous materials.
