1.1本指南涵盖并提供了处理磨损或侵蚀实验室间试验数据的方向。它描述了在委员会G02标准中输入数据和随后报告精度测量结果的格式。它指出了计算所需统计量的方法。 1.2本指南基于委员会G02共识提供指导，旨在强调使用既定统计惯例的必要性，并在报告委员会G02标准中的实验室间测试结果时引入更统一的方法。 1.3本指南中描述的方法如何应用的示例以个人计算机格式作为电子表格文件提供。目的是便于使用本指南中的方法。示例文件以推荐的格式包含所有需要的公式，可以编辑以接受新数据。 联系ASTM总部或G02主席获取该计算机文件的副本。用户必须具有可用的电子表格软件（EXCEL或兼容软件）。 1.4本文件中使用的方法与实践一致 E691 和 E177 . ====意义和用途====== 4.1本指南旨在帮助制定精度声明和支持数据，用于委员会G02标准。这些方法和途径是从实践中得出的 E177 和 E691 . 有人认为，本指南的编制及其在G02委员会中的使用将导致适当的统计分析，并使G02标准在报告实验室间结果和精度方面更加统一。本指南并不是为了替代实践的可能使用 E177 或 E691 在制定委员会标准时。

1.1 This guide covers and offers direction on the handling of data from interlaboratory tests for wear or erosion. It describes a format for entering data and for subsequently reporting results on measures of precision in a Committee G02 standard. It indicates methods for calculation of the needed statistical quantities. 1.2 This guide offers guidance based on a Committee G02 consensus, and exists for the purpose of emphasizing the need to use established statistical practices, and to introduce more uniformity in reporting interlaboratory test results in Committee G02 standards. 1.3 An example of how the methods described in this guide may be applied is available in personal computer format as a spreadsheet file. The purpose is to facilitate use of the methods in this guide. The example file contains all needed equations in the recommended format and can be edited to accept new data. Contact ASTM Headquarters or the Chairman of G02 for a copy of that computer file. The user must have spreadsheet software (EXCEL or compatible) available. 1.4 The methods used in this document are consistent with Practices E691 and E177 . ====== Significance And Use ====== 4.1 This guide is intended to assist in developing statements of precision and supporting data that will be used in Committee G02 standards. The methods and approach are drawn from Practice E177 and E691 . It was felt that preparation of this guide and its use in Committee G02 would lead to appropriate statistical analyses and more uniformity in G02 standards regarding reporting of interlaboratory results and precision. The guide is not meant to substitute for possible use of Practices E177 or E691 in developing committee standards.
