1.1 这些测试方法涵盖了某些非金属衬垫材料在室温下拉伸强度的测定。涵盖的材料类型是分类中所述的含有石棉和其他无机纤维（第1类）、软木（第2类）、纤维素或其他有机纤维（第3类）和柔性石墨（第5类）的材料 F104 这些测试方法不适用于硫化橡胶的测试，其方法在测试方法中描述 D412 也不适用于橡胶O形圈，其方法见试验方法 D1414 . 1.2 以SI单位表示的值应被视为标准。括号中的值仅供参考。 1.3 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。1.4 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》中确立的国际公认的标准化原则制定的。 ======意义和用途====== 4.1 描述这些测试方法是为了标准化测定非金属垫片材料拉伸强度的程序。这种性质的测量表征了给定类型的材料的各种类别和等级，这样做，它将为制造商提供其产品质量的测量。它还将帮助垫圈材料的购买者能够确定他已经批准用于给定应用的垫圈材料是否以可接受的质量制造。4.2 该性能的测量不应被误解为向垫片材料的购买者提供该材料在应用中的性能的指示。 4.3 该特性可用于建立材料规格。 4.4 针对不同类型的材料给出了各种程序，为了比较一个实验室与另一个实验室的结果，必须选择适用的程序。 4.5 允许使用各种类型的张力测试设备。这些类型的设备可以产生不同的指示结果。具有不同设备的实验室可能必须建立彼此之间的相关性；否则，可能会导致对测试数据的误解。

1.1 These test methods cover the determination of tensile strength of certain nonmetallic gasketing materials at room temperature. The types of materials covered are those containing asbestos and other inorganic fibers (Type 1), cork (Type 2), cellulose or other organic fiber (Type 3), and flexible graphite (Type 5) as described in Classification F104 . These test methods are not applicable to the testing of vulcanized rubber, a method for which is described in Test Methods D412 nor for rubber O-rings, a method for which is described in Test Methods D1414 . 1.2 The values stated in SI units are to be regarded as the standard. The values in parentheses are for information only. 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 These test methods are described in order to standardize procedures for determining the tensile strength of nonmetallic gasket materials. The measurement of this property characterizes various classes and grades of materials of a given type and in so doing, it will give the manufacturer a measurement of the quality of his product. It also will aid the purchaser of the gasketing materials to be able to determine whether the gasket material that he has approved for a given application is being manufactured in acceptable quality. 4.2 The measurement of this property should not be misconstrued as to give the purchaser of the gasket material an indication of the performance of that material in application. 4.3 The property may be useful in establishing material specifications. 4.4 Various procedures are given for the different types of materials, and in order to compare the results from one laboratory to another, it is imperative that the applicable procedure be selected. 4.5 Various types of tension-testing apparatus are allowed to be used. These types of equipment can produce different indicated results. Laboratories having different equipment may have to establish correlations between each other; otherwise, misinterpretation of the test data could result.
