3. One, Two or Three Appraisers can be evaluated. Note: If only One is selected, Reproducibility cannot be evaluated . One, Two or Three Trials can be conducted. Note: If only One is selected, Repeatability cannot be evaluated . 5 – 10 Samples can be utilised. Note: Min 5 to ensure statistical validity 1 – 5.15 or 6 SD can be utilised. Note: in conjunction with Maximum Acceptable Error. Required if measurements used for Process Control. Note: Industry Norm requires Cp 1.67 for Short Term Control. Parameters to be applied for the Study The Responsible Person must decide on what Logistical & Statistical Parameters will be applied during the Study. Note 2 : - A basic understanding of Statistical Methodology is required to establish procedures for the selection of statistical parameters. Industry Norm suggests Maximum Acceptable Error. 10% max for Critical Values. 30% for non-critical Values

4. The Study should encompass a typical minimum Sample Data Range that would normally be found in 6 SD of a Process with a long term capability of Cp=>1.33 . Data representing >80% of expected process variation is an industry norm. Note 1:- The sequence or timing of Production from which samples are extracted are not required in consecutive sequence such as used in a Process Capability Study. Note 2:- R&R uses the variation in the Process Samples to generate a Part Variation value, however this should NOT be used as a measure of Process Capability. Part Variation can be used to evaluate if the Samples represent sufficient of the Process Tolerance / Spread to ensure the Study is valid throughout the potential Measurement Range. 5 – 10 Samples can be utilised. Note: Min 5 to ensure statistical validity Sample Collection Full Study Ideally the Sample Values should be distributed evenly through the Tolerance Band. In practice this is not always easy as it infers preliminary measurement must be made in order to select the Products with the appropriate measurements.

5. Appraiser - Data Collection 5 – 10 Samples will have been collected to be used for the Study. Decisions will have been made as to How many Appraisers will be used & how many Trials will be used Procedure Print data Collection Sheet. Number the Samples discreetly 1 - ?? Appraiser 1 measure samples in random order & record. Subsequent Appraisers independently measure samples & record. Enter Appraiser Details in Data Entry Sheet Appraiser 1 & Subsequent Appraisers repeat and record the sample measurements, dependent on the number of Trials required. using the equipment and method nominated in the Product Control Plan.
