本SAE航空航天推荐规程（ARP）描述了一种对金属加工（如电镀、阳极氧化和转化涂层及相关工艺）中所用溶液的分析频率进行分类的方法，但其用途不限于此类应用。本文件旨在制定一个周期性试验计划，供加工商使用，以满足航空航天材料规范（AMS）对化学处理溶液周期性试验计划作为控制因素的要求。本文件不符合正式统计过程控制程序的标准。

This SAE Aerospace Recommended Practice (ARP) describes a method for classifying the frequencies of analysis of solutions used in the processing of metals, such as electroplating, anodizing, and conversion coating and associated processes but usage is not limited to such applications.This document is intended to establish a periodic test plan that may be used by processors to satisfy the requirement of an Aerospace Material Specification (AMS) for a chemical processing solution periodic test plan as a control factor.This document does not fulfill the criteria for a formal statistical process control program.
