Upper foam , Cellulose and Non-woven insole material1. Weigh the specimen in grams (m).2. Multiply the gram weight of the specimen by 100, to obtain the weight g/m² (grams per square meter), as laid out in GE-07.3. Measure the thickness of foam according to DIN 53353 (d) in mm, as laid out in GE-05.4. Calculate the specific gravity acc. to evaluation section A)
