本标准实施规程列出了天然水和废水分析中使用的各种参数。由于环境原因，对这些水域的分析正日益成为人们关注的领域。随着公众意识的提高，管理天然水道使用和限制向这些水道排放的法律的通过，对这些数据的需求大大增加。为确保该数据准确可靠，必须使用已知结果可重复的标准程序进行测试。以下参数的测试方法来自大多数运输部门测试水所使用的参考来源。 它们按最常用参数到很少使用的参数的顺序列出。

This standard practice provides a listing of various parameters used in the analysis of natural waters and wastewaters. The analysis of these waters is becoming an increasing area of concern for environmental reasons. The passage of laws governing the usage of our natural waterways and limiting the discharges into these waterways, along with an increased public awareness, have caused a much greater demand for this information. To ensure that these data are accurate and reliable, it is essential that testing be conducted using standard procedures that are known to have reproducible results. The test methods given for the following parameters are from referenced sources that are used by most transportation departments testing water. They are listed in order of most frequently used parameters to those parameters rarely used.
