1.1 本试验方法包括厚度小于1 本试验方法仅包括试验程序，不包括规范或公差。 1.2 本试验方法中给出的程序适用于计算机控制的恒定伸长率拉伸试验设备。 1.3 以国际单位制表示的值应视为标准值。本标准不包括其他测量单位。 1.4 本标准并不旨在解决与其使用相关的所有安全问题（如有）。 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，并确定监管限制的适用性。 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《国际标准、指南和建议制定原则决定》中确立的国际公认标准化原则制定的。 =====意义和用途====== 5.1 测试芳纶纸时获得的拉伸性能水平取决于试样的年龄和历史以及测试过程中使用的特定条件。这些条件包括拉伸速率、夹具类型、试样标距长度、大气温度和湿度、穿过试样的气流速率以及试样的温度和水分含量。因此，精确规定了测试条件，以获得特定样品的可重复测试结果。 5.2 在设计各种类型的产品时，拉伸强度用于工程计算。 5.3 由于纸张的伸长率对成品的均匀性和使用过程中的尺寸稳定性有影响，因此在设计和工程加固产品时应考虑纸张的伸长率。 5.4 刚度是纸张在施加力时抵抗拉伸的量度。 5.5 拉伸能量吸收取决于力与伸长率的关系。 它是衡量织物结构吸收机械能的能力。拉伸能量吸收是每个区域的断裂功。 5.6 应该强调的是，尽管前面的参数与产品的性能有关，但产品的实际配置是重要的。形状、尺寸和内部结构也会对产品性能产生明显影响。因此，不可能仅从增强材料方面评估最终产品的性能。 5.7 如果两个实验室（或多个）的报告测试结果之间存在实际意义上的差异，则应进行比较测试，以确定它们之间是否存在统计偏差，并使用适当的统计协助。作为最低要求，应使用尽可能均匀的测试样本，这些样本取自获得不同测试结果的材料，并随机分配给每个实验室进行测试。 可使用具有既定试验值的其他材料。两个实验室的测试结果应使用未配对数据的统计测试进行比较，其概率水平应在测试系列之前选定。如果发现偏差，必须找到并纠正其原因，或者必须考虑已知偏差调整未来的测试结果。

1.1 This test method covers the tensile testing of aramid paper with thickness less than 1 mm. This test method includes testing procedures only and includes no specifications or tolerances. 1.2 The procedures given in this test method are for use with computer-controlled constant-rate-of-elongation tensile testing equipment. 1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this 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 ====== 5.1 The levels of tensile properties obtained when testing aramid paper are dependent on the age and history of the specimen and on the specific conditions used during the test. Among these conditions are rate of stretching, type of clamps, gauge length of specimen, temperature and humidity of the atmosphere, rate of airflow across the specimen, and temperature and moisture content of the specimen. Testing conditions accordingly are specified precisely to obtain reproducible test results on a specific sample. 5.2 Tensile strength is used in engineering calculations when designing various types of products. 5.3 Elongation of the paper is taken into consideration in the design and engineering of reinforced products because of its effect on uniformity of the finished product and its dimensional stability during service. 5.4 Stiffness is a measure of the resistance of the paper to extension as a force is applied. 5.5 Tensile Energy Absorption is dependent on the relationship of force to elongation. It is a measure of the ability of a textile structure to absorb mechanical energy. Tensile Energy Absorption is work-to-break per area. 5.6 It should be emphasized that, although the preceding parameters are related to the performance of the product, the actual configuration of the product is significant. Shape, size, and internal construction also can have appreciable effects on product performance. It is not possible, therefore, to evaluate the performance of the end product in terms of the reinforcing material alone. 5.7 If there are differences of practical significance between reported test results for two laboratories (or more), comparative tests should be performed to determine if there is a statistical bias between them, using competent statistical assistance. As a minimum, test samples should be used that are as homogeneous as possible, that are drawn from the material from which the disparate test results were obtained, and that are randomly assigned in equal numbers to each laboratory for testing. Other materials with established test values may be used for this purpose. The test results from the two laboratories should be compared using a statistical test for unpaired data, at a probability level chosen prior to the testing series. If a bias is found, either its cause must be found and corrected, or future test results must be adjusted in consideration of the known bias.
