This test method is suitable for all No. Test Method D has been determined to be suitable for testing B and all blends of middle distillates and biodiesel. Higher levels of particulate contaminant can be measured, but are subject to uncertain precision. No other units of measurement are included in this standard.

If the filtrate is to be subsequently tested for stability it is advisable not to use copper as copper ions catalyze gum formation during the stability test. A fuel and solvent resistance rubber hose through which the grounding wire passes shall connect the sidearm of the receiving flask to the tube passing through the rubber stopper in the top of the safety flask.
Air ionizers shall be replaced within one year of manufacture. NOTE 3 - When using a solid-pan balance, the air ionizer may be omitted provided that, when weighing a membrane filter, it is placed on the pan so that no part protrudes over the edge of the pan. A standard laboratory wash bottle can also be used provided the flushing fluid is pre-filtered through a 0. NOTE 5 - Small watch glasses, approximately 5 to 7 cm in diameter, have also been found suitable to support the membrane filters.
Reagents and Materials 7. 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. Other grades may be used, provided it is first ascertained that the reagent is of sufficient purity to permit its use without lessening the accuracy of the determination.
NOTE 7 - Membrane filters with a grid imprinted on their surface, may be used as control membrane filters for identification. Contact with us now Your mail: Our mail: sales dgaequipment.

This test method is suitable for all No. See Test Methods D and D for means of determining particulate contamination in Specification D aviation turbine fuels and other similar aviation fuels. See Guide D for a more detailed discussion of static electricity formation and discharge. Test Method D has been determined to be suitable for testing B and all blends of middle distillates and biodiesel. Samples containing biodiesel can result in partial dissolution or compromise of the membrane filters and give erroneous results. Higher levels of particulate contaminant can be measured, but are subject to uncertain precision. No other units of measurement are included in this standard.
