1.1 本规程旨在用于测定物理试验用橡胶制品和试样的几何尺寸。本规程描述了确定长度、宽度、厚度、直径和周长的程序。本规程不包括材料或产品的取样，也不包括取样地点。 1.2 以可接受的公制单位或其他单位表示的值应单独视为标准。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，而不以任何其他方式组合值。 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====== 4.1 本规程中规定的尺寸测量用于以下目的之一:( 1. )确定整个装置的几何特性是否符合规范要求，如橡胶手套的尺寸或橡胶软管的直径和周长( 2. )确定是否符合有关装置特定功能部件的规范要求，例如靴子鞋底的厚度，或( 3. )确定在计算物理性能试验结果时所需的几何值，这些物理性能的要求是明确的，例如抗拉强度试样的厚度。使用的方法应符合详细规范或适当试验方法的规定。 4.2 测量仪器施加的压力对观察到的软柔性材料厚度有显著影响，因此有必要规定仪器底部施加在试样上的压力，以便对此类材料进行准确的比较测量。

1.1 This practice is intended for use in determining the geometrical dimensions of rubber products and specimens for physical tests. This practice describes procedures for determining length, width, thickness, diameter, and circumference. This practice does not cover sampling of materials or products, or locations where a sample is to be taken. 1.2 The values stated in either acceptable metric units or in other units shall be regarded separately as a standard. The values stated in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any other way. 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 ====== 4.1 Dimensional measurements specified in this practice are made for one of the following purposes: ( 1 ) to determine conformance with specification requirements regarding geometrical properties of whole units, such as the size of rubber gloves, or the diameter and circumference of rubber hose, ( 2 ) to determine conformance with specification requirements regarding particular functional parts of units, such as the thickness of the soles of boots, or ( 3 ) to determine geometrical values that are necessary in the calculation of test results for physical properties for which requirements are specified, such as the thickness of a test specimen for tensile strength. The method to be used shall be as specified in the detail specification or appropriate test method. 4.2 Pressure applied by measuring instruments has a significant effect on the observed thickness of soft flexible materials, and it is therefore necessary to specify the pressure imposed by the foot of the instrument on the test piece for accurate comparative measurements of such materials.
