1.1 这些测试方法涵盖了释放衬垫与压敏粘合剂标签粘合剂粘附性的测量。 1.2 这些测试方法提供了评估给定类型压敏标签衬里粘附均匀性的方法。评估可以在板材或卷之间或生产批次之间的板材或卷内进行。 1.3 标签背衬、衬垫、衬垫释放涂层、粘合剂和粘合剂涂层重量的变化会影响响应。因此，这些方法不能用于确定不均匀性的具体原因。 1.4 这些测试方法可能不适用于测试具有相对硬背衬或硬内衬，或在低力下显示高拉伸的背衬的标签。这些特性将导致测试响应的高度可变性，而这并不是粘合剂真实性质的真实指示。 1.5 以SI或英寸表示的值- 磅单位应单独视为标准单位。每个系统中规定的值可能不是精确的等效值；因此，每个系统必须独立使用，不得以任何方式组合值。 1.6 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、健康和环境实践，并确定监管限制的适用性。 1.7 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认标准化原则制定的。 ====意义和用途====== 5.1 这些测试方法是开发和质量保证使用的工具。 给定特定的压敏标签和衬垫，以及从标签上移除衬垫时预期的最大剥离值的最小值要求，测试数据可与验收标准结合使用。

1.1 These test methods cover the measurement of the adherence of the release liner to the adhesive of a pressure-sensitive adhesive label. 1.2 These test methods provide means of assessing the uniformity of the adhesion to the liner of a given type of pressure-sensitive label. The assessment may be within a sheet or roll between sheets or rolls or between production lots. 1.3 Variation in the label backing, liner, liner release coating, adhesive, and adhesive coating weight, affect the response. Therefore, these methods cannot be used to pinpoint the specific cause(s) of nonuniformity. 1.4 These test methods may not be appropriate to test labels having either relatively stiff backings or stiff liners, or backings showing high stretch at low forces. These characteristics will result in a high variability of the test response that is not a true indication of the real nature of the adhesive bond. 1.5 The values stated in either SI 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 must be used independently, without combining values in any way. 1.6 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 5.1 These test methods are a tool for development and quality assurance use. Given a specific pressure-sensitive label and liner and a requirement in terms of the minimum for maximum peel value expected for this liner removal from the label, the data from the test can be used in conjunction with acceptance criteria.
