This Apparatus for determination the water vapor
absorption of leather is applied to all types of leathers especially
for leather uppers and lining of footwear or other types of materials for making
uppers and lining of footwear such as all kinds of textile and lining of other
materials, as waterproof textile laminates, etc ..
Also, result of testing the water vapour absorption together with the result of
water vapor permeability is necessary to calculate the water vapor coefficient
as an important physical quality indicators.
Apparatus is made according to the requirements and apply for the tests
according to the following standards:
EN ISO 17229, Leather – Physical and mechanical tests – Determination of water
EN 13515 Footwear absorption test methods for uppers and lining Water vapour
EN ISO 20344 Personal protective equipment – Test methods for footwear
6 Test methods for upper, lining and tongue
6.7 Determination of water vapour absorption (WVA)
6.8 Determination of water vapour coefficient
Into the test vessel pour the prescribed amount of distilled water, on the
opening of the container adjust a test sample which covers the seal and then
strengthen a cover. Containers with samples are positioned on the stand and
placed in the area with the prescribed conditions of temperature of 23 ± 2 °C.
Description of the device:
The device consists of six (6) test containers with a seal and a cover that are
placed on the stand, and the pressure knife for preparing - cutting the samples.
