标准摘要
[中文适用范围]： 本文件规定了使用边界材料和感兴趣的测试条件确定土工织物或土工织物相关产品平面内恒定水头流量的方法。 提出了一系列标准测试条件，包括土壤限制、低水力梯度、就座时间和一系列正常载荷。 [外文原描述]： This document specifies a method for determining the constant-head water flow capacity within the plane of a geotextile or geotextile-related product, using boundary materials and test conditions of interest. A standard series of test conditions are proposed, involving soil confinement, low hydraulic gradients, seating times and an array of normal loads.
