prBAS ISO 17491-5:2025

This document specifies a test method for determining the resistance of complete protective clothing to inward leakage of liquid chemicals (protective clothing integrity). This method specifies an alternative method for determining the resistance to spray penetration because it uses a static manikin instead of a test subject; it also uses a different spray configuration and duration than the other methods within ISO 17491 series. This test method is aligned with ASTM F1359 since the only laboratories with equipment of this kind are performing testing according to that standard. This test method is not appropriate for evaluating the permeation or penetration of liquid chemicals through the material from which the clothing is made.
