1.1 本试验方法包括测定压敏胶带和标签在平行于胶带和基材表面施加的恒定载荷下保持粘附能力的程序。 1.1.1 程序A测量应用于垂直标准钢板时的剪切粘附力。 1.1.2 当应用于覆盖有NIST SRM 1810A标准纤维板的垂直面板时，程序B测量剪切粘附力。 1.1.3 程序C测量当施加到由欧洲标准化委员会(CEN)定义的覆盖有纤维板的垂直面板时的剪切粘附力。 1.1.4 程序D测量应用于覆盖有买卖双方商定的纤维板的垂直面板时的剪切附着力。 1.1.5 程序E测量长丝增强带施加到水平标准钢板时的剪切粘附力。1.1.6 程序F测量长丝增强带施加到覆盖有NIST SRM 1810A标准纤维板的水平面板时的剪切粘附力。 1.1.7 程序G测量长丝增强带施加到覆盖有CEN定义的标准纤维板的水平面板时的剪切粘附力。 1.1.8 程序H测量剪切粘附力与程序A相同，不同之处在于测试在升高的温度下并且在升高的温度下停留10分钟后进行。 1.2 这些程序提供了一种评估给定类型的压敏胶带（通常用于包装应用的胶带）的粘合剂均匀性的方法。评估可以在一卷胶带内、卷或生产批次之间进行。 1.2.1 胶带背衬和粘合剂的变化会影响响应；因此，这些程序不能用于确定不均匀性的具体原因。 1.2.2 本试验方法旨在取代AFERA 4012、CEN 1943和PSTC（参见 7.2 ). 1.3 以SI单位或英寸-磅单位表示的值应单独视为标准值。每个系统中陈述的值并不完全等同；因此，每个系统应独立使用。合并两个系统的值将导致不符合标准。 1.4 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。1.5 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》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 4.1 程序A测量压敏胶带在恒定应力下粘附到标准钢板的能力。这可能涉及也可能不涉及胶带粘附到其他表面的能力。 4.2 程序B、C和D可用于确定通常用于在包装应用中封闭纤维板箱的胶带的剪切粘附力。 4.3 程序D测量压敏胶带对非标准纤维板、衬板、瓦楞纸板或其他商定用于测试的表面的剪切粘附力。这可用于比较胶带与特定纤维板表面的剪切粘附性或比较胶带与各种纤维板表面的剪切粘附性。 4.3.1 类似纤维板的表面在轧机之间、来自一个轧机的批次之间以及批次内可能表现出相当大的变化。在选择样品和比较可能不完全相同的纤维板表面之间的结果时要小心。 4.3.2 在非标准表面上进行的测试精度可能与第节中描述的不同 13 . 4.4 程序E、F和G可用于确定细丝增强带在置于恒定应力下时的保持能力。 4.5 程序H可用于比较施加到标准钢表面并在高温下测试的胶带的剪切粘附力。在测试期间使用升高的温度倾向于减少测试的持续时间。

1.1 This test method covers procedures for determining the ability of pressure-sensitive tapes and labels to remain adhered under constant load applied parallel to the surface of the tape and substrate. 1.1.1 Procedure A measures the shear adhesion when applied to a vertical standard steel panel. 1.1.2 Procedure B measures the shear adhesion when applied to vertical panel covered with NIST SRM 1810A standard fiberboard. 1.1.3 Procedure C measures the shear adhesion when applied to a vertical panel covered with a fiberboard as defined by Comite Europeen de Normalisation (CEN). 1.1.4 Procedure D measures shear adhesion when applied to a vertical panel covered with a fiberboard agreed upon by the buyer and seller. 1.1.5 Procedure E measures shear adhesion of filament reinforced tape when applied to a horizontal standard steel panel. 1.1.6 Procedure F measures shear adhesion of a filament reinforced tape when applied to a horizontal panel covered with NIST SRM 1810A standard fiberboard. 1.1.7 Procedure G measures the shear adhesion of a filament reinforced tape when applied to a horizontal panel covered with a standard fiberboard defined by CEN. 1.1.8 Procedure H measures the shear adhesion the same as Procedure A except the test is conducted at an elevated temperature and after a 10-min dwell time at the elevated temperature. 1.2 These procedures provide a means of assessing the uniformity of the adhesive of a given type of pressure-sensitive tape, usually tapes used for packaging applications. The assessment may be within a roll of tape, between rolls or production lots. 1.2.1 Variations in the tape backing and adhesive affect the response; therefore, these procedures cannot be used to pinpoint the specific cause(s) of nonuniformity. 1.2.2 This test method is intended to replace AFERA 4012, CEN 1943, and PSTC (see 7.2 ). 1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system are not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems will result in non-conformance with the standard. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.5 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 ====== 4.1 Procedure A measures the ability of a pressure-sensitive tape to adhere to a standard steel panel under constant stress. This may or may not relate to the ability of the tape to adhere to other surfaces. 4.2 Procedures B, C, and D may be used to determine the shear adhesion of the tapes generally used to close fiberboard boxes in packaging applications. 4.3 Procedure D measures the shear adhesion of a pressure-sensitive tape to a nonstandard fiberboard, liner board, corrugated board, or other surfaces which is agreed upon for testing. This may be used to compare the shear adhesion of a tape to a particular fiberboard surface or to compare the shear adhesion of a tape to a variety of fiberboard surfaces. 4.3.1 The surfaces of similar fiberboards may exhibit considerable variation between mills, between batches from one mill, and within batches. Take care in the choice of samples and when comparing results between fiberboard surfaces which may not be exactly the same. 4.3.2 The precision of tests conducted on nonstandard surfaces may be different than that described in Section 13 . 4.4 Procedures E, F, and G may be used to determine the ability of a filament reinforced tape to hold when placed under constant stress. 4.5 Procedure H may be used to compare the shear adhesion of tape applied to a standard steel surface and tested at an elevated temperature. The use of an elevated temperature during test tends to reduce the duration of the test.
