(1)Form A-1 shall be used for the study of a gauge which is used to control process stability, trends and compliance with the daily process variation by measuring process parameters (e.g. press depth, screwing angle, oil temperature, etc.). The assessment criterion in this case is the %GRR to process variation. Note: If the samples used for the study are selected from the process and cover the entire operating range the process variation can be estimated by the Total Variation (TV).
(2)Form B-1 shall be used for the study of a gauge which is used to control the conformance or nonconformance of a specified product characteristics to the specification. The assessment criterion in this case is the %GRR to TOLERANCE.
5.3 Procedure The examiner shall decide the characteristics to be measured, select the measuring persons (appraisers) , prepare the parts and measurement instruments, and shall record the measurement results according to the measurement procedure shown in Table 2.
