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. This standard has either been superceded and replaced by a new version or discontinued.

Sampling NOTE 8—Caution—It is dd6217 to note that d217 entire contents of the sample container are ltered during the conduct of this test method. Using 1 gal of a middle distillate fuel, which can contain greater particulate levels, often required excessive time to complete the ltration. Work Item s – proposed revisions of this d66217. Do not remove the plastic lm from the funnel opening until ready to start ltration.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but d621 not provided as part of the standard. D ashm 98 containers, their caps and petri dishes as described in 8. NOTE 10—Some fuels may lter reasonably rapidly during transfer of the total contents of the sample container through a single set of lter membranes. Current edition approved Jan. Container caps should be handled only externally with clean laboratory crucible tongs during this and subsequent washings.

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. Ensure that the line to be sampled is ushed with astmm before taking the sample.


To minimize operator 4 9. Keep the fuel sample ltrate separate from the solvent washings ltrate. Install the funnel and secure with locking ring or spring clip. Results obtained when analyzing samples with volumes signicantly different than 1 L may have different precision values.

Air ionizers shall be replaced within one year of manufacture. Precision and Bias Shake the container vigorously for about 12min. A fuel and solvent resistance rubber hose through which the grounding wire passes shall connect the sidearm of the receiving ask to the tube passing through the rubber stopper in the top of the safety ask.

Filtration System for ASTM D6217, IP 415

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 ushing uid from the membrane lter. When the level of particulate contamination is low, a single set will usually suffice; when the contamination is high or of a nature that induces slow ltration rates, two or more sets may be required to complete ltration in a reasonable time.

Maximum particulate levels are specied in asmt military fuel specications.

Because of this, take care to protect the sample from any external contamination. This includes not only all of the fuel but also all rinsings of the interior of the container with ushing uid.

The two membrane lters used for each individual test shall be identied by marking the aastm dishes used to hold and transport the lters. This test method provides a means of assessing the mass of particulates present in a fuel sample. Epoxy lined sample cans, d621 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.


Dry and reweigh the membrane lters as described in See Test Methods D and D for means of determining particulate contamination in Specication D f6217 turbine fuels and other similar aviation fuels.

D — 98 FIG. Clean all glassware used in preparation of membrane lters as described in 8. Glass containers are preferred to facilitate a visual inspection of the contents and the container before and after lling.

Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters. See Test Methods D and D for means of determining particulate contamination in Specification D aviation turbine fuels and other similar aviation fuels.

When it is not practical to clean the sampling lines, rinse them thoroughly with the fuel to be sampled. Protect the fuel sample from prolonged exposure to light by wrapping the container in aluminum foil or storing it in the dark to reduce the possibility of particulate formation by light-promoted reactions.

The precision data were obtained by statistical examination of interlaboratory test results using fuels samples of approximately 1 L volume. For fuels containing little particulate materials, only one set of lters is required. 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.

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. NOTE 5—Small watch glasses, approximately 5 to 7 cm in diameter, have also been found suitable to support the membrane lters. With the vacuum applied, carefully separate the funnel from the lter base.

Keep the petri dish cover ajar, but such that the membrane lters are still protected from contamination from the atmosphere.
