1.1本试验方法包括测定装饰革表面的柔韧性和附着力。本试验方法不适用于蓝湿革。 1.2以英寸-磅为单位的数值应视为标准值。括号中给出的值仅供参考。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 该测试方法模拟了使用中的软垫革所受到的弯曲，并认为与使用的相关性良好。可以评估漆面的抗裂性和漆面与皮革的附着力。 这种方法中的皮革受到的弯曲作用比鞋帮皮革方法产生的弯曲作用更严重。 不太严格的测试在评估室内装饰皮革饰面方面几乎没有用处。 该测试方法适用于研究、开发和制造控制，并且非常有用。它被用作规范验收的测试方法。由于这是一项主观测试，在用于规范验收之前，应通过实验室间经验建立适当的相关性。

1.1 This test method covers the determination of the flexibility and adhesion of a finish on upholstery leather. This test method does not apply to wet blue. 1.2 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This test method simulates the flexing received by upholstery leather in service, and correlation with service is believed to be good. Both the resistance of the finish to cracking and adhesion of the finish to the leather can be evaluated. The flexing action received by the leather in this method is more severe than that given by methods for shoe upper leather. The less severe tests have little utility in the evaluation of upholstery leather finishes. This test method is suitable, and has been useful, in research, development, and manufacturing control. It is used as a method of test for specification acceptance. Since this is a subjective test, proper correlation should be established by interlaboratory experience prior to use for specification acceptance.
