1.1 这些试验方法包括用于评估硫化热固性橡胶和热塑性弹性体拉伸（拉伸）性能的程序。这些方法不适用于硬橡胶和类似的硬质、低伸长率材料。方法如下: 试验方法A-哑铃和直截面试样 试验方法B-切割环试样 注1: 这两种不同的方法不会产生相同的结果。 1.2 以国际单位制或非国际单位制表示的数值应单独视为本标准的标准值。 每个系统中的值可能不是精确等价的；因此，每个系统必须独立使用，而不合并值。 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====== 5.1 这些试验方法涵盖的所有材料和产品必须能够承受拉力，以便在某些应用中具有足够的性能。这些试验方法允许测量此类拉伸性能。然而，由于实际使用中存在广泛的潜在性能要求，拉伸性能本身可能与产品的总最终使用性能没有直接关系。 5.2 拉伸性能取决于材料和试验条件（延伸率、温度、湿度、试样几何形状、预试验条件等）。 ); 因此，只有在相同条件下测试时，才应比较材料。 5.3 温度和拉伸速率可能会对拉伸性能产生重大影响，因此应加以控制。这些影响因被测试材料的类型而异。 5.4 拉伸永久变形表示拉伸和收缩后部分永久和部分可恢复的残余变形。因此，必须控制延长期和恢复期（以及其他测试条件），以获得可比结果。

1.1 These test methods cover procedures used to evaluate the tensile (tension) properties of vulcanized thermoset rubbers and thermoplastic elastomers. These methods are not applicable to ebonite and similar hard, low elongation materials. The methods appear as follows: Test Method A—Dumbbell and Straight Section Specimens Test Method B—Cut Ring Specimens Note 1: These two different methods do not produce identical results. 1.2 The values stated in either SI or non-SI units shall be regarded separately as normative for this standard. The values in each system may not be exact equivalents; therefore each system must be used independently, without combining values. 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 All materials and products covered by these test methods must withstand tensile forces for adequate performance in certain applications. These test methods allow for the measurement of such tensile properties. However, tensile properties alone may not directly relate to the total end use performance of the product because of the wide range of potential performance requirements in actual use. 5.2 Tensile properties depend both on the material and the conditions of test (extension rate, temperature, humidity, specimen geometry, pretest conditioning, etc.); therefore materials should be compared only when tested under the same conditions. 5.3 Temperature and rate of extension may have substantial effects on tensile properties and therefore should be controlled. These effects will vary depending on the type of material being tested. 5.4 Tensile set represents residual deformation which is partly permanent and partly recoverable after stretching and retraction. For this reason, the periods of extension and recovery (and other conditions of test) must be controlled to obtain comparable results.
