1.1 本试验方法涵盖压敏胶带和标签的断裂抗拉强度（断裂强度）和拉伸性能（伸长率）的测量。它包括机器方向和交叉方向、高强度纤维增强背衬和高拉伸背衬的程序。它还包括获得力（“F”值）和指定伸长率的程序。这些程序采用恒定延伸率（CRE）型试验机。 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；测量系统之间的转换必须仔细进行。 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、健康和环境实践，并确定监管限制的适用性。 1.4 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 该测试方法提供了可用于产品设计和质量保证应用的材料规范中的信息。它可以用于比较不同的产品。 5.2 本试验方法的使用必须与试验目的相关。 一个目的是根据购买或使用的尺寸确定胶带的相对强度。另一个目的是识别或表征特定的背衬材料。 5.2.1 可在收到的胶带上进行试验，即不将材料切割至小于收到宽度的试样宽度。通常胶带宽度大于48毫米[2英寸]主要由于设备的限制，未进行测试。胶带的宽度约为3毫米[0.125英寸。]可以测试。 5.2.2 可以使用锋利的剃刀（如第节中定义的）在样品材料边界内切割的样品上进行试验 6. . 该方法通常用于材料表征、确定一致性质量和规范一致性。 5.3 断裂伸长率或达到规定伸长率的力的拉伸特性可能与胶带的预期用途或用于识别或表征材料有关。

1.1 This test method covers the measurement of tensile strength at break (breaking strength) and stretch properties (elongation) for pressure-sensitive tapes and labels. It includes procedures for machine direction and cross direction, for high-strength filament reinforced backings and for high stretch backings. It also includes a procedure for obtaining force (“F” value) in conjunction with a specified elongation. These procedures employ a constant-rate-of-extension (CRE)-type testing machine. 1.2 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; conversions between measurement systems must be conducted carefully. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.4 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 provides information that can be used in material specifications for product design and quality assurance applications. It can be used in comparing different products. 5.2 The use of this test method must be related to the purpose for which the test is performed. One purpose is for determining the relative strength of the tape in the size in which it is purchased or used. Another purpose is to identify or characterize a particular backing material. 5.2.1 The test may be performed on the tape as-received, that is, without cutting the material to a specimen width less than the as-received width. Usually tapes wider than 48 mm [2 in.] are not tested due principally to the limitations of equipment. Tapes as narrow as approximately 3 mm [0.125 in.] can be tested. 5.2.2 The test may be performed on a specimen cut from within the sample material boundaries using a sharp razor cutter, such as that defined in Section 6 . This method is usually used for material characterization, determining quality of conformance, and for specification compliance. 5.3 Stretch characteristics of elongation at break or force to a specified elongation can be related to the tape's intended use or for identifying or characterizing a material.
