1.1本试验方法涵盖了在不向封口（IIA型封口）施加向下力的情况下，在翻转凸耳饰面封口时，在容器饰面凸耳（条纹页）上旋转时产生向下力所需的力的测定。 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====== 本试验方法可作为标准试验，用于将给定尺寸和设计的凸耳式儿童防护闭合装置与制造商规范进行比较，以及比较不同材料的类似闭合装置，以确定是否存在剥离。 本试验方法可用作标准试验，以评估在包装的整个预期使用和保质期内，闭合对儿童阻力和成人打开和重新闭合的持续有效性。

1.1 This test method covers the determination of the force required to cause a downward-force-while-turning lug-finish closure to be rotated across the container finish lugs (strippage) without downward force being applied to the closure (Type IIA closures). 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 may be used as a standard test in the comparison of a given size and design lug-style child-resistant closure to manufacturer specifications, and in the comparison of similar closures of differing materials for determining strippage. This test method may be used as a standard test to evaluate the continued effectiveness of the closure for child resistance and adult opening and reclosing throughout the expected use and shelf life of the package.
