1.1本试验方法涵盖分离（或 “ 壳 ” )IA、IB或IC型儿童防护外壳内盖的按扣式外盖。 1.2本试验方法不测量分离最初用于儿童防护的封闭系统部件所需的力 “ 拧紧 ” 而不是 “ 突然 ” （例如，当最初拧上盖子时，将盖子拉过或穿过连续或多头螺纹）。 1.3以国际单位制表示的数值应视为标准。 括号中的英寸-磅单位仅供参考。 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====== 该施力试验方法可用作标准试验，以比较容器/儿童给定设计的特性- 使用标准或比较不同结构的容器/儿童防护封闭系统的特性。 它可用于模拟协议测试中可能会发生的某些操作（例如，用牙齿或房间里的物体撬，用牙齿咬和拉）。 本试验方法可用于制定性能规范。

1.1 This test method covers the measurement of the force required to separate (or “ shell ” ) the snap-fitted outer cap from the inner cap of Type IA, IB, or IC child-resistant closures. 1.2 This test method does not measure the force required to separate parts of a child-resistant closure system that were originally “ screwed-on ” instead of “ snapped-on ” (for example, pull a cap over or through continuous or multi-start threads when the cap was originally screwed on). 1.3 The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are 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 ====== This test method of applying force may be used as a standard test to compare the characteristics of a given design of container/child-resistant closure system with a standard or to compare the characteristics of container/child-resistant closure systems differing in construction. It may be used to simulate certain manipulations that may be expected to occur in protocol testing (such as, prying with the teeth or objects in the room, biting, and pulling with the teeth). This test method may be used to establish performance specifications.
