本规程描述了一种评估替代试验替代标准试验能力的方法。替代试验必须证明能够提供与标准试验方法类似的试验结果，且附加的变异性最小。将标准和替代品的测试结果进行比较，并量化其关系中的误差。在施工或生产过程中，可能需要使用替代试验来监测材料质量，尤其是如果标准试验方法使用复杂/昂贵的设备，需要耗时的样品制备和测试技术，使用危险材料，或涉及破坏部分材料。 本标准操作规程旨在用于施工质量控制，但如果机构特别批准，也可用于验收。在评估潜在替代试验方法并设置其使用参数时，应遵循本标准中的程序。

This practice describes a method to assess the capability of a surrogate test to be used as a substitute for a standard test. The surrogate tests must demonstrate the capability to provide test results similar to the standard test method with a minimum of additional variability. The test results from the standard and the surrogate are compared and the error in their relationship is quantified.It may be desirable to use a surrogate test to monitor material quality during construction or production, especially if the standard test method uses complex/expensive equipment, requires time-consuming sample preparation and testing techniques, uses hazardous materials, or involves destroying a portion of the material. This standard practice is intended to be applied for construction quality control but may also be used for acceptance if specifically approved by the Agency.The procedure in this standard should be followed in the evaluation of potential surrogate test methods and to set parameters for their use.
