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.
This test method provides a means of assessing the mass of particulates present in a fuel sample. Preparation of Apparatus and Sample Containers 8. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phoneasmtor service astm. A number in parentheses indicates the d62117 of last reapproval. 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by the responsible technical committee and must be reviewed every ve years and if not revised, either reapproved or withdrawn.
However, some fuels, due to d217 quantity or nature of particulates, or both, may plug the membrane lter during ltration and require use of multiple successive ltrations.

If the ltrate is to be subsequently tested for stability it is advisable not to use copper as copper ions catalyze gum formation asrm the stability d217. This test method used about a quarter of the volume used in the aviation fuel methods. Because of this, take care to protect the sample from any external contamination. NOTE 5—Small watch adtm, approximately 5 to 7 cm in aztm, have also been found suitable to support asttm membrane lters.
Current edition approved Jan. Similarly protect the funnel opening of the assembled ltration apparatus with a clean protective cover until ready for use.
D — 98 membrane set consists of a tared nylon test membrane and a tared nylon control membrane. Keep the fuel sample ltrate separate from the solvent washings ltrate. 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. Container c6217 should be handled only externally with clean laboratory crucible tongs during this and subsequent washings.
D — 98 containers, their caps and petri dishes as described in 8. Keep the petri dish cover ajar, but such that the membrane lters are still protected from contamination from the atmosphere. Maximum particulate levels are specified in several military fuel specifications. 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.
Higher levels of particulate contaminant can be measured, but are subject to uncertain precision. Ensure that the sample has not passed through intermediate containers prior to placement in the prepared container.
D — 98 robin participants using both water aspirated and mechanical vacuum systems with vacuums ranging from 1 to kPa.
Link to Active This link will always route to the current Active version of the standard. This allows the fuel to be used for additional analyses.
Glass containers also allow for visual inspection of the container, after the sample is emptied, to conrm complete rinsing of the container. Air ionizers x6217 be replaced within one year of manufacture.
Shake the container vigorously for about 12min. When it is not practical to clean the sample containers in this manner, the containers shall be rinsed three times with the awtm to be sampled. Higher levels of particulate contaminant can be measured, but are subject to uncertain precision.

See Guide D for a more detailed discussion of static electricity formation and satm. This test method is suitable for all No. Clean all glassware used in preparation of membrane lters as described in 8.
Work Item s – proposed revisions of this standard. 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. The cooperative test involved 13 laboratories and nine test fuels.
