Test Method: SATRA TM198

Evaluation of water repellency of shoe care products

September 1999

SCOPE

This method is intended to determine the effectiveness of water repellency products when applied to a material. The method takes into account the effect of flexing on the material and is applicable to water repellency products for use on all footwear uppers or other flexible materials.

PRINCIPLE

Test specimens of the material on which the water repellency product is to be tested are repeatedly flexed. A test specimen is then clamped across the bottom of a hollow cylinder and a volume of water poured into the top. The mass of water absorbed by, and transmitted through, the test specimen is measured. The water repellency product is applied to the test specimen and the water absorbance and transmittance are remeasured.
