1.1本试验方法测量操作链锯时为保护下半身（腿）而穿戴的衣服和装置的抗切割性。 1.2本试验方法可用于测试是否符合既定安全标准中的最低性能要求。 1.2.1根据买方和供应商之间的协议，或根据既定安全标准的要求，将决定是否使用本试验方法来确定以下任何一项或全部:（1）阈值停车速度；（2） 在指定链速下的成功/失败（堵塞/链停止）； 或（3）穿越时间。 1.3本试验方法可用于确定既定安全标准中规定的覆盖区域的防护等级。 1.4以国际单位制或英寸磅表示的数值应单独视为标准值。每个系统中规定的值可能不是精确的等效值；因此，每个系统必须相互独立使用，不得以任何方式组合值。 1.5本标准无意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。

1.1 This test method measures cut resistance of garments and devices worn to protect the lower (legs) body when operating a chain saw. 1.2 This test method may be used to test for compliance to minimum performance requirements in established safety standards. 1.2.1 By agreement between the purchaser and the supplier, or as required by established safety standards, it will be decided if this test method will be used to determine any one or all of the following: (1) threshold stopping speed; (2) success/failure (jamming/chain stop) at specified chain speed; or (3) cut through time. 1.3 This test method may be used to determine levels of protection for areas of coverage as stipulated in established safety standards. 1.4 The values stated in SI units or in inch-pound shall be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way. 1.5 This standard does not purport to address all of the safety problems, 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.
