ASTM D6200 Determination of Cooling Characteristics of Quench Oils
ASTM D6200 Standard Test Method for Determination of Cooling Characteristics of Quench Oils by Cooling Curve Analysis
15. Report
15.1 The report shall include cooling time, temperature and cooling rate, and temperature curves for the submitted sample. Recommended data to be reported for each test run are provided in 15.1.1-15.1.3. Additional values shall be reported as required by the purchaser.
15.1.1 From the time/temperature graph, report the time to the nearest 0.1 s at 600°C (1112°F) 400°C (752°F), and 200°C (392°F).
15.1.2 From the temperature/cooling rate graph, report the following:
15.1.2.1 Maximum cooling rate °C/s (°F/s),
15.1.2.2 Temperature where the maximum cooling rate occurs (°C, °F), and
15.1.2.3 Cooling rate at 300°C (572°F).
15.1.3 Report the following information:
15.1.3.1 Date,
15.1.3.2 Identification of sample,
15.1.3.3 Reference to the test method, and
15.1.3.4 Cooling curves and cooling rate curves including calibration curves for the reference oil,
15.1.3.5 Statement of results, and
15.1.3.6 Any modifications to test methods.
16. Precision and Bias
16.1 The precision and bias of the procedure in Test Method D6200 for determining cooling characteristics of quench oils is being determined.
