31、em c) of Clause 8 with ISO 2419:2012.EN ISO 17229:2016 (E) DIN EN ISO 17229:2016-06 41 ScopeThis International Standard specifies a method for determining the water vapour absorption of leather. The method is applicable for all leathers but is particularly relevant for leathers intended for footwear

32、 uppers and linings.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (

33、including any amendments) applies.ISO 2418, Leather Chemical, physical and mechanical and fastness tests Sampling locationISO 2419, Leather Physical and mechanical tests Sample preparation and conditioningISO 3696, Water for analytical laboratory use Specification and test methods3 PrincipleThe test

34、 piece and an impermeable material are clamped over the opening of a metal container containing 50 ml of water for a specified time. The water vapour absorption of the test piece is determined by the increase in mass.4 Apparatus4.1 Cylindrical metal or glass container, with internal diameter of 35 m

35、m 0,5 mm, internal depth 104 mm 1 mm and an external diameter at the top opening of at least 55 mm, fitted with a metal ring or lid which can be securely clamped to the cylindrical metal container.4.2 Balance, weighing to 0,001 g.4.3 Stop clock, reading to 1 min.4.4 Vernier callipers, reading to 0,1

36、 mm.4.5 Disc of impermeable material, for example rubber or metal, with the same diameter as the test piece.4.6 Press knife, the inner wall of which is a right angled circular cylinder of diameter 43 mm 1 mm as specified in ISO 2419.4.7 Distilled or deionized water, conforming to the requirements of

37、 grade 3 of ISO 3696.EN ISO 17229:2016 (E) DIN EN ISO 17229:2016-06 5 5 Sampling and sample preparation5.1 Sample in accordance with ISO 2418. From the sample, cut three circular test pieces by applying the press knife to the grain surface, if distinguishable.If there is a requirement for more than

38、two hides or skins to be tested in one batch, then only one test piece need be taken from each hide or skin, provided that the overall total is not less than three test pieces.5.2 Condition the test piece in accordance with ISO 2419.NOTE Results will vary depending on the conditioning method used.5.

39、3 Weigh the test piece to the nearest 0,001 g and record its mass as m1.6 Procedure6.1 Using vernier callipers, measure the internal diameter of the cylindrical container (to the nearest 0,1 mm) in two mutually perpendicular directions and calculate the mean diameter.6.2 Pour 50 ml 5 ml of distilled

40、 or deionized water at 20 C 2 C or 23 C 2 C into the cylindrical metal container (4.1).6.3 Place the test piece centrally over the container with the side which would be exposed to the higher humidity in use facing downwards. Place a disc of impermeable material over the test piece and clamp the upp

41、er ring or lid in place taking care not to splash water onto the test piece.6.4 Keep the container at a temperature of 20 C 2 C or 23 C 2 C for 8 h 0,1 h.6.5 Remove the test piece, weigh immediately to the nearest 0,001 g and record its mass as m2.6.6 If the test piece is splashed with water discard
