本文描述了一项实验室研究，旨在测试饮用水管内水泥砂浆衬里中受管制金属的可浸出性。这项研究有四个具体目标，分别是:确定水泥砂浆衬里中的金属是否在静态加压条件下（管道消毒后）渗入第一次填充的管道水中；查明在管道消毒过程中，衬里暴露于氯化水、暴露于水龙头水的新鲜填充物以及暴露于软水填充物的情况下，金属是否从衬里中浸出；确定哪些环境促进了浸出； 并根据管道水中金属浓度与当前饮用水标准的比较，确定应向水行业提出哪些建议（如有）。将已知质量的水龙头水引入测试管道，并在静态加压条件下保持较长时间。在测试期间，经常从管道中抽取水样，测试金属和其他水质参数。对研究结果进行了讨论。包括20个参考文献、表格和图表。

This article describes a laboratory study which was conducted to test the leachability of regulated metals from cement-mortar linings inside drinking water pipes. This study had four specific objectives, which were: to determine whether metals from the cement-mortar linings were leaching into the first fill of pipe water (after pipe disinfection) held in a static, pressurized condition; to find out whether metals were leaching from the linings under conditions of exposure of lining to chlorinated water during pipe disinfection, exposure of lining to fresh refills of faucet water, and exposure of lining to refills with soft water; to ascertain which environments promoted leaching; and, to determine what recommendations, if any, should be made to the water industry based on comparisons of the concentrations of metals in the pipe water with current drinking water standards. Faucet water of known quality was introduced in the test pipes and maintained in static, pressurized conditions for extended periods of time. Water samples were frequently drawn from the pipes and tested for metals and other water quality parameters during the test periods. Results of the study are discussed. Includes 20 references, tables, figures.
