    Withdrawn Rationale:

    This guide covered and offered direction on the handling of data from interlaboratory tests for wear or erosion. It described a format for entering data and for subsequently reporting results on measures of precision in a Committee G02 standard. It indicated methods for calculation of the needed statistical quantities.

    Formerly under the jurisdiction of Committee G02 on Wear and Erosion, this guide was withdrawn in November 2016. This standard is being withdrawn without replacement due to its limited use by industry.

    1. Scope

    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.
