1.1 这些测试方法涵盖混凝土管道、混凝土箱形截面、人孔截面和瓷砖的测试。所述测试方法用于生产测试和验收测试，以评估规范中提供的性能。 1.2 试验方法按以下顺序出现: 部分 外载抗压强度 4. 平板顶部 5. 基础截面试验方法 6. 核心实力 7. 吸收 8. 静水压 9 渗透 10 人孔台阶 11 气缸强度 12 垫片润滑剂 13 接头剪力 14 碱度 15 垫片测量 16 偏心静水压接头试验 17 静水压外部接头试验方法 18 焊接接头拉力试验 19 1.3 试验前24小时内，试样不得暴露在低于40°F的温度下。 1.4 如果任何试样因机械原因（如测试设备故障或试样制备不当）而失败，则应丢弃该试样，并取下另一个试样。 1.5 应根据测试管道或瓷砖类型的规范选择样本。 1.6 测试方法的完整公制配套工具 C497 已开发- C497M ; 因此，这些方法中没有度量等价物。 1.7 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。 1.8 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。

1.1 These test methods cover testing of concrete pipe, concrete box sections, manhole sections, and tile. The test methods described are used in production testing and acceptance testing to evaluate the properties provided for in the specifications. 1.2 The test methods appear in the following order: Section External Load Crushing Strength 4 Flat Slab Top 5 Base Section Test Method 6 Core Strength 7 Absorption 8 Hydrostatic 9 Permeability 10 Manhole Step 11 Cylinder Strength 12 Gasket Lubricant 13 Joint Shear 14 Alkalinity 15 Gasket Measurements 16 Off-Center Hydrostatic Joint Test 17 Hydrostatic External Joint Test Method 18 Welded Splice Pull Test 19 1.3 The test specimens shall not have been exposed to a temperature below 40°F for the 24 h immediately preceding the test. 1.4 If any test specimen fails because of mechanical reasons such as failure of testing equipment or improper specimen preparation, it shall be discarded and another specimen taken. 1.5 Specimens shall be selected in accordance with the specifications for the type of pipe or tile being tested. 1.6 A complete metric companion to Test Methods C497 has been developed— C497M ; therefore, no metric equivalents are presented in these methods. 1.7 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. 1.8 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.
