5、ound. 2.0 SCOPE This specification describes the test method 3.0 APPARATUS 3.1 Balance with a sensitivity of 0.1 gram 3.2 Gravity-convection oven capable of maintaining 212 + 2 degrees Fahrenheit 3.3 Desiccator 3.4 Petri dish, approximately 100 millimeters in diameter and 15 millimeters in depth 4.0
6、 PROCEDURE 4.1 Weigh the Petri dish to the nearest 0.1 gram. 4.2 Place approximately 20 grams of sample into the dish and weigh sample and dish to the nearest 0.1 gram. 4.3 Set the dish into the gravity-convection oven maintained at 212 + 2 degrees Fahrenheit and heat for 48 hours. 4.4 At the end of
7、 the 48-hour period remove the dish from the oven, place in a desiccator, and allow to cool to room temperature. 4.5 Weigh the dish and its contents to the nearest 0.1 gram. 5.0 REPORT 5.1 Calculate the volatile matter as follows: % Volatile matter = (A-B) 100S where A = weight of dish and sample in grams B = weight of dish and residue in grams S = weight of sample in grams REPORT THE VALUE OBTAINED AS “VOLATILE MATTER, % BY WEIGHT”.
