10.2 Adjusting the Volume Loss—As the rubber wheel decreases in diameter the amount of scratching abrasion developed in a given practice will be reduced accordingly. The actual volume loss produced by these slightly smaller wheels will, therefore, be inaccurate. The “adjusted volume loss” value takes this into account and indicates the actual abrasion rate that would be produced by a 228.6-mm (9.00-in.) diameter wheel. Calculate the adjusted volume loss (AVL) as follows:
10.3 Reporting Test Results—All significant test parameters and test data as noted in Tables 2 and 3 shall be reported. Any variation from the recommended procedure must be noted in the comments. The report shall include a statement of the current precision and accuracy of the test apparatus as qualified by the testing of Reference Materials (11.6). The volume loss data developed by the initial qualification tests (11.4) or the volume loss data developed by the periodic re-qualification tests (11.4.3) should be listed on the data sheet (Table 3).
