This Standard specifies a test method to measure repellency, retention and penetration of a known volume of liquid pesticide when applied to protective clothing material. This method is designed to rate relative performance of personal protective equipment (PPE) materials at two levels of contamination. This test method is suitable for field strength and concentrated pesticide formulations.
