1.1本试验方法评估座椅在装配位置的自升式或自动升降座椅机构的性能。 1.2本试验方法仅涉及座椅的升高。它没有解决可能放置在该座椅上的负载。F15委员会正在考虑解决这一负荷的标准。 1.3以英寸-磅为单位的数值应视为标准值。括号中的值仅供参考。 1.4 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====== 3.1本试验方法提供了实用、可重复试验的标准，以确保座椅的自升式或自动升降座椅机构的正确寿命周期。 3.2本试验方法应适用于设计目的、制造控制、服务评估、规范验收和法规要求的试验。

1.1 This test method evaluates the performance of self-rising or automatic-lifting seat mechanisms of chairs in places of assembly. 1.2 This test method addresses only the raising of the seat. It does not address the load that may be placed on that seat. Committee F15 is considering a standard addressing this load. 1.3 The values as stated in inch-pound units are to be regarded as the standard. The values in parentheses are provided for information only. 1.4 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 ====== 3.1 This test method provides the criteria for a practical, reproducible test for assuring the proper life-cycle of self-rising or automatic-lifting seat mechanisms of chairs. 3.2 This test method should be considered suitable for the testing required for design purposes, manufacturing control, service evaluation, specification acceptance, and regulatory statutes.
