Test Method: SATRA TM98

Dimensional stability with changes in atmospheric humidity

June 1992

SCOPE

This test method is intended to determine the dimensional stability of a material with changes in atmospheric humidity. The method is applicable to all types of hygroscopic flat sheet material such as insole boards.

PRINCIPLE

Two marks are made on the surface of a test specimen before it is stored for 48 hours in an atmosphere at low humidity. The distance between the marks is then measured and the specimen is stored for a further 48 hours in an atmosphere at high humidity. The distance between the marks is measured again and the percentage increase is determined.
