Follow the steps to complete the form successfully:

1. Click ‘Get Form’ button to obtain the form and open it in the editor.
2. Begin by completing the project identification and any other required heading information lines at the top of the form.
3. Tabulate your Quality Assurance (QA) data for the project using Form 1965. Ensure that you include all relevant G*/sin δ values obtained during QA testing.
4. Calculate the average (y) and standard deviation (s) of all QA data. You can utilize an automatic electronic method or follow the specified equations provided in the document.
5. On the y-axis of your control chart, locate and label the value of 2.20, drawing a horizontal line across the graph and designating it as the Specification Limit.
6. Identify corresponding points on the y-axis at y, y + s, y + 2s, y + 3s, y - s, y - 2s, and y - 3s and draw horizontal lines across the graph.
7. Label the lines you drew in the previous step as Mean, Upper Control Limit (UCL), and Lower Control Limit (LCL) as applicable.
8. Designate the various zones on the control chart: Zone C between y and y ± s, Zone B between y ± s and y ± 2s, and Zone A between y ± 2s and y ± 3s.
9. Indicate each data point below the x-axis with the sample identification and the numeric value of G*/sin δ.
10. Plot each QA data point on the Statistical Process Control (SPC) Chart above their corresponding sample identifications using a dot symbol.
11. Similarly, identify and plot any Verification data points using an 'x' symbol above their sample identifications.
12. Ensure that you complete and save all required forms. You can download, print, or share the completed form as needed.
