United States16.1.1 The oven shall be equipped with a calibrated ASTM thermometer and the proper stem correction shall be applied to thetemperature measurement.6.1.2 The oven temperature
15、shall be controlled by an accurate, reliable thermoregulator, maintaining the set point within60.5C61.0C or better.6.1.3 The inside of the oven shall be free of contamination or surface deposits.

16、 gases.6.2 Sample ContainerA weighing vessel of low shape design in glass, aluminum, or stainless steel of sufficient size to holda 10-g resin sample. An aluminum weighing dish, 57 mm in diameter and 18 mm in depth, is suitable.NOTE 2An aluminum weighing dish, 57 mm in diameter and 18 mm in depth, i
17、s suitable.6.3 BalanceA weighing balance with a precision to within 0.001 g.7. Preparation of Apparatus7.1 Maintain the oven at the temperature of the test for at least 1 h prior to insertion of the specimens.7.2 Prior to test operation, verify the uniformity of temperature within the oven according
18、 to Specification E145. The airflowin the oven should be greater than 0.3 m3/min (10 ft3/min).NOTE 3The temperature uniformity can also be verified by placing 5 or more portions of the same resin sample in the oven, distributed over the testarea, following Section 8. Calculate the percent of volatil
19、e loss (Section 9). If the differences in the volatile loss of the samples exceed the testreproducibility, the temperature in the oven is not uniform and must be corrected before proceeding with the test.8. Procedure8.1 Dry the weighing vessel in the oven at 110 6 1C for 30 min and cool to room temp
20、erature in a desiccator.Tare the weighingvessel to the nearest 0.001 g.8.2 Spread approximately 10 g of sample resin evenly over the bottom of the weighing vessel and weigh to the nearest 0.001g. Record the sample mass.8.3 Place the resin-filled weighing dish in the oven controlled at 110 6 1C and c
21、lose the oven.8.4 After 1 h, remove the weighing dish, cool to room temperature in a desiccator, and weigh to the nearest 0.001 g. Returnthe weighing dish to the oven and heat for an additional 15 min, cool to room temperature in the desiccator, and re-weigh. Constantmass is reached when the success
22、ive weighing differs by 0.001 g or less; if the mass variation is greater than 0.001, continue the15 min heating-weighing cycle until constant mass is obtained.NOTE 4Prompt weighing after removal of the dish from desiccator will improve accuracy.8.5 Test a minimum of two samples, and average the res
