1.1 本试验方法涵盖了压敏标签原料剥离附着力的测量。该测试方法给出了对标准钢基底或对压敏标签原料感兴趣的其他表面的粘附性的量度。 1.2 该测试方法提供了一种评估给定类型的压敏标签原料的粘附均匀性的方法。评估可以在片材或卷材内、片材或卷材之间、或生产批次之间。 1.3 标签原料面材和粘合剂的变化会影响响应；因此，该试验方法不能用于确定不均匀性的具体原因。 1.4 该测试方法可能不适用于测试具有硬背衬或在低力下显示高拉伸的背衬的标签原料。这些特性可能导致测试响应的高度可变性，这不是粘合剂结合的真实性质的真实指示。 1.5 以SI或英寸-磅单位表示的值应单独视为标准。每个系统中陈述的值可能不完全等同；因此，每个系统必须独立使用，不能以任何方式组合值。 1.6 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 1.7 本国际标准是根据世界贸易组织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的标准化原则制定的iers贸易（TBT）委员会。 ======意义和用途====== 5.1 该测试方法是质量保证使用的工具。给定压敏标签原料以及该标签原料预期的最小或最大剥离粘合值的要求，测试数据可与验收标准结合使用。 5.2 与标准不锈钢板相比，该测试方法可以显示给定标签原料与不同材料和纹理的一个或多个表面的相对粘合强度。在该程序中，可以用代表拟定基材的面板代替标准不锈钢板。

1.1 This test method covers the measurement of the peel adhesion of pressure-sensitive label stocks. This test method gives a measure of the adherence to a standard steel substrate or to other surfaces of interest for a pressure-sensitive label stock. 1.2 This test method provides a means of assessing the uniformity of the adhesion of a given type of pressure-sensitive label stock. The assessment may be within a sheet or roll, between sheets or rolls, or between production lots. 1.3 Variations in the label stock facestock and adhesive can affect the response; therefore, this test method cannot be used to pinpoint the specific cause(s) of nonuniformity. 1.4 This test method may not be appropriate to test label stocks having either stiff backings or backings showing a high stretch at low forces. These characteristics could result in a high variability of the test response, which 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 the 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 This test method is a tool for quality assurance use. Given a pressure-sensitive label stock and a requirement in terms of the minimum or maximum peel adhesion value expected for this label stock, the data from the test can be used in conjunction with acceptance criteria. 5.2 This test method can show the relative bond strength of a given label stock to one or more surfaces of varied material and texture as compared to the standard stainless steel panel. Substitution of panels representative of the proposed substrates for the standard stainless steel panel would be acceptable for this procedure.
