Higher levels of particulate contaminant can be measured, but are subject to uncertain precision. Active view current version of standard. Preparation of Membrane Filters Summary of Test Method 4. A superscript epsilon e indicates an editorial change since the last revision or reapproval. Because of this, take care to protect the sample from any external contamination. D — 98 exposure to fumes, the ltering procedure should be performed in a fume hood. 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.
Glass containers are preferred to facilitate a visual inspection of the contents and the container before and after lling. To facilitate handling, the membrane lters should rest on clean glass support rods, or watch glasses, in petri dish. Ensure that the line to be sampled is ushed with fuel before taking the sample.
D — 98 FIG. However, some fuels, due to the quantity or nature of particulates, or both, may plug the membrane lter during ltration and require use of multiple successive ltrations. When it is not practical to clean the sample containers in this manner, the containers shall be rinsed three times with the fuel to be sampled. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
This test method used about a quarter of the volume used in the aviation fuel methods. See Test Methods D and D for means of determining particulate contamination in Specification D aviation turbine fuels and other similar aviation fuels.
For atm 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.
Precision and Bias Maximum particulate levels are specified in several military fuel specifications. 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. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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. 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. 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.
See Test Methods D and D for means of determining particulate contamination in Specication D aviation turbine fuels and other similar aviation fuels.
Filtration System for ASTM D6217, IP 415
See Test Methods D and D for means of determining particulate contamination in Specification D aviation turbine fuels and other similar aviation fuels. Test Method D has been determined to be suitable for testing B and all blends of d627 distillates and biodiesel. Air ionizers shall be replaced within one year of manufacture. Clean all glassware used in preparation of membrane lters as described in 8. To facilitate the latter, it is advisable to use smaller cleaned graduated transfer cylinders of mL capacity.

This includes not only all of the fuel d6271 also all rinsings of the interior of the container with ushing uid. D — 98 membrane set consists of a tared nylon test membrane and a tared nylon control membrane.
Maximum particulate levels are specied in several v6217 fuel specications. 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. Ensure that the sample has not passed through intermediate containers prior to placement in the prepared container.
Work Item s – proposed revisions of this standard. This test method is suitable for all No.
Historical Version s – view previous versions of standard. NOTE 10—Some fuels may lter reasonably rapidly during transfer of the ast contents of the sample container through a single set of lter membranes.
Test Method Sstm has been determined to be suitable for testing B and all blends of middle distillates and biodiesel. D — 98 robin participants using both water aspirated and mechanical vacuum systems with vacuums ranging from 1 to kPa.
Samples containing biodiesel can result in partial dissolution or compromise of the membrane filters and give erroneous results. Current edition approved Jan. 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. 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.
Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Allow 30 min for the membrane lters to come to equilibrium with room air temperature and humidity. See Guide D for a more detailed discussion of static electricity formation and discharge. Link to Active This link will always route to the current Active version of the standard. Samples containing biodiesel can result in partial dissolution or compromise of the membrane filters and give erroneous results.
Similarly protect the funnel opening of the assembled ltration apparatus with a clean protective cover until ready for use. Higher levels of particulate contaminant can be measured, but are subject to uncertain precision. The cooperative test involved 13 laboratories and nine test fuels. NOTE 5—Small watch glasses, approximately 5 to 7 cm in diameter, have also been found suitable to support the membrane lters.
