ISO 4920:2012 specifies a spray test method for determining the resistance of any fabric, which might or might not have been given a water‑resistant or water‑repellent finish, to surface wetting by water. It is not intended for use in predicting the rain-penetration resistance of fabrics, since it does not measure penetration of water through the fabric.
Abstract
Overview
ISO 4920:2012 - - specifies a standardized spray test to assess a fabric’s by water. The method measures how well the face of a fabric resists wetting (spray rating) and is widely used to evaluate water‑resistant or water‑repellent finishes. It is explicitly intended to predict rain‑penetration resistance because it does not measure water penetration through the fabric.
