Current version: ISO 16925:2021 (2nd edition, published in December 2021), replacing ISO 16925:2014

Technical Committee: ISO/TC 35 (Paints and Varnishes) / SC 9 (General Test Methods)

ICS Classification: 87.040 (Coatings, Varnishes)

China's standard adoption status: No equivalent/equivalent national standard GB/T 16925; domestic standards are often directly referenced or converted into industry methods on the National Standard Information Public Service Platform

Scope of application: Laboratory simulation of damage to coatings caused by high-pressure water jet cleaning, assessing the coating's resistance to detachment, peeling, and adhesion retention

Test principle: Spray the coating sample with high-pressure water jet at specified pressure, flow rate, nozzle distance/angle, and temperature. Conduct visual/photographic comparison, measure the peeling area, and determine the water jet resistance level
