ASTM D7583 Standard Test Method for John Deere Coolant Cavitation Test
12. Report
12.1 Report Forms - For reference coolant tests the standardized report form set and data dictionary for reporting test results and for summarizing the operational data are required. The report forms and data dictionary are available from the TMC. Instructions for obtaining the report forms and data dictionary and a list of report forms are shown in Annex A8.
12.1.1 Report latest stand Reference Data, Pit Counts, Operational Summary, Coolant and Oil Analysis, Downtime, and Photographs on the appropriate form in the test report.
12.2 Reference Coolant Test - Send the test report forms and any other supporting information, to the TMC by facsimile or electronic transmission within five days of the EOT date for test acceptance determination. Reference oil test reports should be mailed or electronically transmitted to the TMC within 30 days of the EOT date.
12.3 Electronic Transmission of Test Results - Use ASTM Data Communications Committee Test Report Transmission Model (Section 2 - Flat File Transmission Format).
13. Precision and Bias
13.1 Precision - Precision is based on operationally valid calibration test results monitored by the TMC. The research report contains industry data developed prior to the establishment of this test method.
13.1.1 Intermediate Precision (formerly called repeatability) Conditions - Conditions where test results are obtained with the same test method using the same test coolant, with changing conditions such as operators, measuring equipment, test stands, test engines, and time.
13.1.2 Intermediate Precision Limit (i.p.) - The difference between two results obtained under intermediate precision conditions that would in the long run, in the normal and correct conduct of the test method, exceed the values shown in Table 1 in only one case in twenty.
13.2 Reproducibility Conditions - Conditions where test results are obtained with the same test method using the same test coolant in different laboratories with different operators using different equipment.
13.2.1 Reproducibility Limit (R) - The difference between two results obtained under reproducibility conditions that would, in the long run, in the normal and correct conduct of the test method, exceed the values in Table 5 in only one case in twenty.
13.3 Bias - Bias is determined by applying a defined statistical technique to calibration test results. When a significant bias is determined, a severity adjustment is applied to the non-reference coolant test result.
