Gage Repeatability and Reproducibility in Hardness Testing[1]
-
Published:2000
Abstract
The gage repeatability and reproducibility (GRR) study is a procedure for determining the repeatability of a test instrument and the reproducibility of a specific gage in operation. This article reviews the general method of GRR studies and its application for indentation hardness testing. It describes a long method and a short method for evaluation of GRR. The article analyzes factors of hardness testing instruments and provides guidelines for hardness tests. It concludes with a list of suggestions that can improve hardness tests.
