Significance and Use3.1 This test method may be used to measure the effective-ness of water resistant treatments of light leathers such as gloveand gar

6、ment leather that have no finish. It can also be used tomeasure the water absorption capacity of insole materials thusproviding a gage for predicting foot comfort or discomfort.4. Apparatus4.1 Washing MachineA Launder-Ometer,4or an assemblyof apparatus capable of similar test conditions (see Note 1)

7、. Ineither machine, 1-pt (500-mL) specimen containers are heldwith their bases toward a horizontal shaft and 2 in. (50 mm) outfrom its center of rotation. Speed of rotation shall be 40 to 45rpm. Provision shall be made for maintaining the initialtemperature of the specimen containers throughout the

8、test.NOTE 1A motor-driven assembly, designed to hold 1-pt (500-mL)specimen containers so that they are relative to the axis of the motor shaftin the same way as in the Launder-Ometer, can be used.5The entireassembly, fitted with specimen containers, shall be turned at 40 to 45 rpminside a simple box

9、like container. Such an apparatus is illustrated in Figs.1 and 2.4.2 Specimen Containers,6glass or stainless steel, 1-pt (500-mL), washer, and cap, or Mason jar,7top inside diameter 238in. (60.3 mm) and 4 in. (100 mm) high including thread, withthreaded lid and insert.4.3 Balance, sensitive to 0.01

10、g or better (high speedbalance preferred for readings to nearest 0.01 g).4.4 Roll of Pressure-Sensitive Adhesive (Both Sides) Paper,1 in. (25.4 mm) wide (for light leathers).4.5 Rubber Rings, 0.8 to 1.6 mm thick, Type A durometerhardness 50 to 80, inner diameter 214 in. (57 mm), to fit intolids (for

11、 light leathers).1This test method is under the jurisdiction of ASTM Committee D31 on Leatherand is the direct responsibility of Subcommittee D31.04 on ApparelThis test methodwas developed from Federal Test Method Standard No. 311, Method 8151 incooperation with the U.S. Army Natick Research Develop
