The ash content shall be determined in accordance with ASTM D 1506-75 with the following exceptions: a. The sample shall not be dried prior to weighing. b. The sample shall be ignited at 950

21、OC. c. The calculation shall be corrected so that c = weight of crucible plus the sample, g, and d = weight of crucible plus the ash, g. 4.5.3 Ether extract. The ether extract shall be d accordance with the following: termined in a. b. Weigh a sample of approximately 10 grams (9) of carbon black to

22、the nearest 0.1 mg Transfer the sample to an extraction thimble and extract with ether using a tared extraction flask and a Soxhlet extractor or equivalent. Use a hot-water bath or a steam plate as the source of heat. Adjust the applied heat so that ether drops from the reflux condenser at the rate

23、of 2 to 3 drops per second. Continue the extraction for 8 hours. Remove the extraction flask and evaporate the ether by heating on a steam bath until approximately 25 millilitres (ml) of the ether solution remains. Complete the evaporation to dryness by blowing a slow current of dry air over the sol
