Link to Active This link will always route to the current Active version of the atm. D — 98 FIG. Work Item s – proposed revisions of this standard.
To facilitate handling, the membrane lters should rest on clean glass support rods, or watch glasses, in petri dish. Precision and Bias 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by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn. Allow 30 min for the membrane lters to come to equilibrium with room air temperature and humidity. This standard has either been superceded and replaced by a new version or discontinued.
A superscript epsilon e indicates an editorial change since the last revision or reapproval. Higher levels of particulate contaminant can be measured, but are subject to uncertain precision.
Record the nal control membrane lter mass and the nal test membrane lter mass to the nearest 0. 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. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Calculation and Report NOTE 2—The electrical bonding apparatus described in Test Method D or other suitable means of electrical grounding which ensure safe operation of the ltration apparatus and ask can be used. Weigh it, record the initial mass to the nearest 0. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.
NOTE 5—Small watch glasses, approximately 5 to 7 cm in diameter, have also been found suitable to support the membrane lters. D — 98 membrane set consists of a tared nylon test membrane and a tared nylon control membrane.
Maintain vacuum after the nal washing for 10 to 15 s to remove excess ltered v6217 uid from the membrane lter. Link to Active This link will always route to the current Active version of the standard. Using 1 gal of a middle distillate fuel, which can contain greater particulate levels, often required excessive time to complete the ltration.

Users of this standard are expressly advised that determination of the validity of any such patent rights, and e6217 risk of infringement of such rights, are entirely their own responsibility.
D — 98 containers, their caps and petri dishes as described in 8. Glass containers are preferred to facilitate a visual r6217 of the contents and the container before and after lling. Higher levels of particulate contaminant can be measured, but are subject to uncertain precision. Each 3 4 1. The cooperative test involved 13 laboratories and nine test fuels. Preparation of Membrane Filters This test method used about a quarter of the volume used in the aviation fuel methods.
Samples containing biodiesel can result in partial dissolution or compromise of the membrane filters and give erroneous results. Because of this, take care to protect the sample from any external contamination. A number in parentheses indicates the year of last reapproval.

Astj 10—Some fuels may lter reasonably rapidly during transfer of the total contents of the sample container through a single set of lter membranes. NOTE 9—Caution—Samples obtained from static storage may give results which are not representative of the bulk contents of the tank because of particulate matter settling.
If all the fuel has been ltered, thoroughly rinse the sample container and the graduated cylinder d66217 one d66217 more portions of ltered ushing uid and pour the rinses into the funnel and proceed to Air ionizers shall be replaced within one year of manufacture. Shake the container vigorously for about 12min. Samples should preferentially be obtained dynamically from a sampling loop in a distribution line, or from the ushing line of a eld sampling kit.
