Leather. Physical test methods. Determination of water resistance of heavy leathers1 Scope This International Standard specifies a method for determining the water resistance of heavy leathers. The method allows determination of the penetration time, water absorption, area of penetration and water penetration rate as required. It is applicable to all types of heavy leathers.
