1.1 本规程描述了土工织物耐液体化学性测试程序。加固土工织物也可以按照实践进行测试 D6213 。 1.2 本规程描述了测量平面尺寸、拉伸性能和其他可选物理、机械和液压性能变化的测试方法，这些变化是由浸入测试液体引起的，可能代表预期的最终使用条件。这种做法可用于评估产品的制造性能受这种浸泡影响的程度。 1.3 本规程旨在与任一规程结合使用 D5322 或 D5496 本规程的范围仅限于未暴露和暴露土工布样品的测试和报告程序。 1.4 测试数据的评估或解释超出了本规范的范围。 1.5 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的使用者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。 有关具体警告说明，请参阅第节 7. 。 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒委员会发布的《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====== 5.1 本规程提供了一种测试程序，用于确定土工布对液体废物、渗滤液或化学品的耐受性。 在没有针对所处理的特定情况所需的其他规范的情况下，应使用此做法。 5.2 本规程中的试验程序规范旨在为那些希望比较或研究土工织物对潜在恶劣化学环境的耐化学性的人提供指导。 5.3 本规程适用于土工织物的耐化学性评估，与土工膜、土工格栅、土工网和土工管的类似标准规程并行编写。每一项标准都将针对正在调查的土工合成材料单独考虑，并针对所有暴露在潜在恶劣化学环境中的土工复合材料进行集体考虑。

1.1 This practice describes the procedures used for testing geotextiles for chemical resistance to liquids. Reinforcement geotextiles can also be tested per Practice D6213 . 1.2 This practice describes test methods for measuring changes in planar dimensions, tensile properties, and other optional physical, mechanical, and hydraulic properties caused by immersion in test liquids which may be representative of anticipated end-use conditions. This practice may be used to assess the extent to which a product's as-manufactured properties are affected by such immersion. 1.3 This practice is intended to be used in conjunction with either Practice D5322 or D5496 . The scope of this practice is limited to testing and reporting procedures for unexposed and exposed geotextile samples. 1.4 Evaluation or interpretation of test data is beyond the scope of this practice. 1.5 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. For specific warning statements, see Section 7 . 1.6 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 This practice provides a test procedure for determining the resistance of a geotextile with a liquid waste, leachate, or chemical. This practice should be used in the absence of other specifications required for the particular situation being addressed. 5.2 The specification of test procedures in this practice is intended to serve as a guide for those wishing to compare or investigate the chemical resistance of a geotextile to a potentially harsh chemical environment. 5.3 This practice is for the chemical resistance assessment of geotextiles and is written in parallel to similar standard practices for geomembranes, geogrids, geonets, and geopipes. Each standard is to be considered individually for the geosynthetic under investigation and collectively for all geosynthetics exposed to the potentially harsh chemical environment under consideration.
