This document specifies a test method for determining the resistance to water leakage and penetration of water-resistant clothing in an artificial rainfall using a manikin capable of marching motion. It determines the waterproof characteristic in practical use in a rainfall environment with the wearer moving. In addition to personal protective equipment and outdoor clothing, which require extreme conditions, it also applies to testing common waterproof or water-repellent products such as jackets, trousers, coats, and one- or two-piece suits.

The test method described in this document uses manikin with normal adult male size, excluding other sizes (female, children).
