For fuels containing little particulate materials, only one set of lters is required. If the ltrate is to be subsequently tested for stability it is advisable not to use copper as copper ions catalyze gum formation during the stability test.
Using 1 gal of a middle distillate fuel, which can contain greater particulate levels, often required excessive time to complete the ltration. Unless otherwise indicated, it is intended that all reagents shall conform to the specications of the Committee on Analytical Reagents of the American Chemical Society, where such specications are available.
This standard is subject to revision at any time by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn. Container caps should be handled only externally with clean laboratory crucible tongs during this and subsequent washings.
Users of this standard are expressly advised that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility.
Clean all glassware used in preparation of membrane lters as described in 8. D — 98 containers, their caps and petri dishes as described in 8. Active view current version of standard.
Samples containing biodiesel can result in partial dissolution or compromise of the membrane filters and give erroneous results. Signicance and Use 5. The two membrane lters used for each individual test shall be identied by marking the petri dishes used to hold and transport the lters. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. To minimize operator 4 9. Calculation and Report If all the fuel has been ltered, thoroughly rinse the sample container and the graduated cylinder with one or more portions of ltered ushing uid and pour the rinses into the funnel and proceed to Dry and reweigh the membrane lters as described in See Guide D for a more detailed discussion of static electricity formation and discharge.

Historical Version s – view previous versions of standard. No other units of measurement are included in this standard. This test method used about a quarter of the volume used in the aviation fuel methods.
See Guide D for a more detailed discussion of static electricity formation and discharge. Higher levels of particulate contaminant can be measured, but are subject to uncertain precision. Maximum particulate levels are specied in several military fuel specications. Place the weighed test membrane lter on top of the control membrane lter. Sampling NOTE 8—Caution—It is important to note that the entire contents of the sample container are ltered during the conduct of this test method.
The entire contents of the sample container shall be ltered through the membrane lters to ensure a correct measure of the particulate contamination in the aatm.

Air ionizers shall be replaced within one year of manufacture. See Test Methods D and D for means of determining particulate contamination in Specication D aviation turbine fuels and other similar aviation fuels. If you feel that your comments have not received a fair hearing you should make your views known to the ASTM Committee on Standards, at the address shown below. Weigh it, record the initial mass to the nearest 0.
This test method is suitable for all No. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
Where possible, the contents of the tank should be circulated or agitated before sampling, or the sampling performed shortly after a tank has been lled. A number in parentheses indicates the year of last reapproval. Wash the periphery of the membrane lter by directing a gentle stream of ltered ushing uid from the edge to the center, exercising care not to wash any of the particulate from the surface of the membrane lter. Link to Active This link will always route to the current Active version of the standard.
This test method provides a means of assessing the mass of particulates present in a fuel sample. To facilitate handling, the membrane lters should rest on clean glass support rods, or watch glasses, in petri dish. The cooperative test involved 13 laboratories and nine test fuels.
Maintain vacuum after the nal washing for 10 to 15 s to remove excess ltered ushing uid from the membrane lter. Summary of Test Method 4. Preparation of Apparatus and Sample Containers 8. Epoxy lined sample cans, polytetrauoroethylene PTFE bottles, and high density linear polyethylene bottles have also been found suitable as sample containers but are less desirable since visual inspection of the interior of the container is more difficult.
A standard laboratory wash bottle can also be used provided the ushing uid is pre-ltered through a 0. Glass containers also allow for visual inspection of the container, after the sample is emptied, to conrm complete rinsing of the container.
D — 98 membrane set consists of a tared nylon test membrane d621 a tared nylon control membrane. NOTE 3—When using a solid-pan balance, the air ionizer may be omitted provided that, when weighing a membrane lter, it is placed on the pan so that no part protrudes over the edge of the pan. D62217 Method D has been determined to be suitable for testing B and all blends of middle distillates and biodiesel.
