ASTM D1121 method for Reserve Alkalinity of Engine Coolants and Antirusts
13. Report
13.1 Report the sample description and the reserve alkalinity to the nearest 0.1 mL of 0.100 N HCl for the standard 10-mL sample. Sample description may vary from a simple identification number to a complete history and analysis, such as that utilized for used coolants from laboratory performance and vehicle service tests.
14. Precision and Bias
14.1 Repeatability - Duplicate results by the same operator should not be considered suspect unless they differ by more than more or less 0.2 mL.
14.2 Reproducibility - The results submitted by two or more laboratories should not be considered suspect unless the results differ by more than more or less 0.2 mL.
