5、sts3. Terminology3.1 Definitions of terms used in this test method can befound in Terminology D 1517.3.2 Definitions of Terms Specific to This Standard:3.2.1 tackiness, adjthe tendency of cloth to adhere toleather.4. Summary of Test Method4.1 Finished leather is brought into contact with a test clot

6、hunder a prescribed pressure. The apparatus is heated for aprescribed time, then cooled to room temperature. The clothsubsequently is peeled from the finished leather while observ-ing the force to remove the cloth and deformation of thefinished leather surface.5. Significance and Use5.1 This test me

7、thod is intended for use on any type offinished leather.5.2 This test will give an indication of the tackiness of thefinish on leather.6. Apparatus6.1 A circulating oven capable of maintaining 50 6 2C(122 6 3.6F).6.2 A piece of bleached cheesecloth measuring at least 10by 10 cm (3.94 by 3.94 in.).6.

8、3 A suitable device for maintaining a pressure of 100g/cm2(1.42 lb/in.2) over the entire surface of the cheesecloth.7. Sampling, Test Specimens, and Test Units7.1 Sample leather according to Practice D 2813.7.2 The leather sample shall be larger than the cheesecloth.8. Conditioning8.1 Prepare the te

9、st pieces according to Practice D 1610.8.2 Conditioning, other than as prescribed, shall be docu-mented in the results.9. Procedure9.1 The finished leather specimen, the cheesecloth, and thedevice for maintaining pressure shall be placed in the ovenseparately and brought to the required temperature.

10、9.2 Apply the cheesecloth to the surface of the leather.Apply and maintain a pressure of 100 g/cm2evenly over thesurface of the cheesecloth for 5 min while remaining in theoven.9.3 Remove the pressure from the cheesecloth, and removethe finished leather and cheesecloth while still in contact withit

11、from the oven.9.4 Allow the finished leather and cheesecloth to cool underconditions specified by Practice D 1610.1This test method is under the jurisdiction of ASTM Committee D31 on Leatherand is the direct responsibility of Subcommittee D31.07 on Physical Properties.Current edition approved April

22、h was dislodged by a light force as evidenced by the clothloosening in sections rather than along a line.3 The cheesecloth was dislodged by a greater force as evidenced by abend developing with a small radius along a line perpendicular to thedirection of peeling. The surface of the leather has no tr

23、ace of cheeseclothfibers remaining after a puff of air is applied.4 Fibers from the cheesecloth remain adhering to the finished leather or thesurface of the leather has been deformed by the peeling action.5 The cheesecloth tears when being removed or the finish peels off theleather substrate or leather finish adheres to the cheesecloth.D 6183 00 (2005)2
