ASTM E – 87 Gross Calorific Calorimeter – PDF Free Download
Collect the washings in a beaker and titrate the washings with standard carbonate solution. The pressure gauge shall be checked periodically for accuracy. Recommended hygienic practices include use of gloves when handling RDF astk washing hands before eating or smoking. The amount of water g is usual can be most satisfactorily determined by weighing the calorimeter vessel and water together on a balance.
For spe cautionary and precautionary statements see 6. The chairman of E Unless otherwise indicated, it is intended that all reagents shall conform to the specifications of the Committee on Analytical Reagents of the American Chemical Society, where such specifications are available.
Thermometer Accessories – A magnifier is required for reading mercury-in-glass thermometers to one tenth of the smallest scale division. Fire the charge at the start of the sixth minute and record the time and temperature. This is e7111 number that is multiplied by the corrected temperature rise in degrees and divided by the sample weight in grams to give the gross calorific value after thermochemical corrections have been applied. Tap mercurial thermometers with a pencil just before reading to avoid errors caused by mercury sticking to the walls of the capillary.
ASTM E711 – 87 Gross Calorific Calorimeter
Due to the origins of RDF in municipal waste, common sense indicates that some precautions should be observed when conducting tests on the samples. Weigh the sample to the nearest 0. The maximum difference between any two test points shall not be more than 0. Firing Circuit – A 6 to 16V alternating or direct current is required for ignition purposes with an ammeter or pilot light in the circuit to indicate when current is flowing. There shall be no gas leakage during a test.
Valves, gages, and gaskets must meet industry safety codes. Carefully weigh approximately 1g of the sample directly into the crucible in which it is to be burned or into a tared weighing scoop which the sample is transferred to the crucible.
ASTM E (Re-approved ) – International Standards
Each millilitre of standard alkali is equivalent to This standard does not purport to address all of the safety concerns, if any, associated with its use. Suitable reducing valves and adapters for 2 to 3. If the bomb is lined with platinum or gold, all openings shall be sealed to prevent combustion products from reaching the base metal. A stepdown transformer connected to an alternating current lighting circuit or batteries may be used.
Before adding this water, rinse the bomb, and drain the excess water, and atsm undried. The pressure gage shall be checked periodically for accuracy. Carefully weigh approximately 1 g of the sample directly into the crucible in which it is to be burned or into a tared 7e11 scoop from which the sample is transferred to the crucible. It shall have a device for stirring the water thoroughly and at a uniform rate, but with minimum heat input. The sampling method for this procedure should be based on agreement between the involved parties.
Water in Bomb – Add 1.
Temperature changes may also be recorded in electromotive force, ohms, or other units when other types of temperature sensors are used. Adjust the jacket temperature to be equal to or slightly lower than the calorimeter, and run for 5 min to obtain equilibrium.
Weight of sample – Thoroughly mix the analysis sample of solid fuel in the sample bottle, taking care that the heavies and lights fluff are distributed in the sample. Detach the filling connection and exhaust the bomb in the usual manner. Terminology refuse-derived fuels—soli 3. Purity of Water – Unless otherwise indicated, references to water shall be understood to mean reagent water.
Determine the sulfur content of the sample by any of the procedures described in Test Methods E The maximum difference in correction between any two test points shall not be more than 0. The usual range of weight is 0. Examine the bomb interior and discard the test if unburned sample or sooty deposits are found.
