ASTM D4340 Standard Test Method for Corrosion of Cast Aluminum Alloys in Engine Coolants Under Heat-Rejecting Conditions
15. Report
15.1 Report the following information:
15.1.1 Report the heat-transfer corrosion rate to the nearest 0.1 mg/cm2/week of each specimen.
15.1.2 The appearance of each specimen, such as pitting, crevice attack, color, and residual corrosion products.
15.1.3 The appearance and final pH of test coolant.
16. Precision and Bias
16.1 Precision - The precision of the procedure in this test method for measuring corrosion of cast aluminum alloys in engine coolants under heat-rejected conditions is being determined.
16.2 Bias - Since there is no accepted reference material suitable for determining the bias for the procedure in this test method, bias has not been determined.
