Summary of Test Method4.1 This test method consists of heating at 110C a knownquantity of powdered resin to constant

8、mass. The calculatedmass loss defines quantitatively the volatile matter present inthe sample.5. Significance and Use5.1 The quantity of volatile components in a vinyl chlorideresin can be established by this test method. This test methoddoes not identify the components.6. Apparatus6.1 OvenA forced-

9、ventilation oven conforming to therequirements for Type IIA in Specification E145. The ovenshould be capable of maintaining a temperature of 110 6 1Cwhen the damper is half open and the vent is wide open.6.1.1 The oven shall be equipped with a calibrated ASTMthermometer and the proper stem correctio

10、n shall be applied tothe temperature measurement.6.1.2 The oven temperature shall be controlled by anaccurate, reliable thermoregulator, maintaining the set pointwithin 61.0C or better.6.1.3 The inside of the oven shall be free of contaminationor surface deposits. Stainless steel oven liners should

11、be usedto reduce corrosion due to continued exposure to decomposi-tion gases.6.2 Sample ContainerA weighing vessel of low shapedesign in glass, aluminum, or stainless steel of sufficient size tohold a 10-g resin sample.1This test method is under the jurisdiction of ASTM Committee D20 on Plasticsand

16、s suitable.6.3 BalanceAweighing balance with a precision to within0.001 g.7. Preparation of Apparatus7.1 Maintain the oven at the temperature of the test for atleast 1 h prior to insertion of the specimens.7.2 Prior to test operation, verify the uniformity of tempera-ture within the oven according t

17、o Specification E145. Theairflow in the oven should be greater than 0.3 m3/min (10ft3/min).NOTE 3The temperature uniformity can also be verified by placing 5or more portions of the same resin sample in the oven, distributed over thetest area, following Section 8. Calculate the percent of volatile lo

18、ss(Section 9). If the differences in the volatile loss of the samples exceed thetest reproducibility, the temperature in the oven is not uniform and mustbe corrected before proceeding with the test.8. Procedure8.1 Dry the weighing vessel in the oven at 110 6 1C for 30min and cool to room temperature

19、 in a desiccator. Tare theweighing vessel to the nearest 0.001 g.8.2 Spread approximately 10 g of sample resin evenly overthe bottom of the weighing vessel and weigh to the nearest0.001 g. Record the sample mass.8.3 Place the resin-filled weighing dish in the oven con-trolled at 110 6 1C and close t

20、he oven.8.4 After 1 h, remove the weighing dish, cool to roomtemperature in a desiccator, and weigh to the nearest 0.001 g.Return the weighing dish to the oven and heat for an additional15 min, cool to room temperature in the desiccator, andre-weigh. Constant mass is reached when the successiveweigh

21、ing differs by 0.001 g or less; if the mass variation isgreater than 0.001, continue the 15 min heating-weighing cycleuntil constant mass is obtained.NOTE 4Prompt weighing after removal of the dish from desiccatorwill improve accuracy.8.5 Test a minimum of two samples, and average the results.9. Cal

22、culation9.1 For each determination calculate the mass percent ofvolatile matter present as follows:M 2 M!/M# 3100where:M and M = respectively, the mass before and after heatingof the resin determined at room temperature (atemperature in the range from 20 to 30C (68 to85F), as defined in Methods D618

Precision and Bias11.1 The following should be used for judging the accept-ability of results (95 % confidence limits):11.2 Reproducibility Limit, RThe value below whic

24、h theabsolute difference between two test results obtained underreproducibility conditions is likely to be expected to occur witha probability of approximately 0.95 (95 %).11.3 Repeatability Limit, rThe value below which theabsolute difference between two individual test results obtainedunder repeat

25、ability conditions is likely to be expected to occurwith a probability of approximately 0.95 (95 %).11.4 Equivalence testing on numerical data from twosources shall be conducted in accordance with Practice E2935or any known method for judging the equivalence of twomeans.NOTE 5Example: a t-test.11.5

26、BiasNo justifiable statement of bias can be made forthis test method, since the true value of the property cannot beestablished by an accepted referee method.NOTE 6Other techniques of volatile determinations may be substi-tuted at the option of the purchaser and seller, such as the use of asemi-auto

27、matic moisture tester or a procedure employing an infrared lampas a heating source. With such methods, the temperature of the heatedsample must be maintained at 110 6 1C.12.
