1.1本试验方法涵盖了机械泵分配器浸渍管的测定技术。 1.2以国际单位制或英寸-磅单位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，每个系统应相互独立使用。将两个系统的值合并可能会导致不符合标准。 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====== 本试验方法用于确定机械泵分配器的浸入管延伸至容器底部角落的长度。 本试验方法用于确定机械泵分配器的浸入管延伸至容器底部中心的长度。

1.1 This test method covers the determination technique for a dip tube of a mechanical pump dispenser. 1.2 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard. 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 is to be used to determine the length of a dip tube of a mechanical pump dispenser that extends to the bottom-corner of a container. This test method is to be used to determine the length of a dip tube of a mechanical pump dispenser that extends to the bottom-center of a container.
