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. 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.

To minimize operator 4 9. Dry and reweigh the membrane lters as described in Maintain vacuum after the nal washing for 10 to 15 s to remove excess ltered ushing uid from the membrane lter. 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.

With the vacuum satm, carefully separate the funnel from the lter base. Clean all glassware used in preparation of membrane lters as described in 8. Precision and Bias A superscript epsilon e indicates an editorial change since the d66217 revision or reapproval. Glass containers also allow for visual inspection of the container, after the sample is asttm, to conrm complete rinsing of the container. Higher levels of particulate contaminant can be measured, but are subject to uncertain precision.

Test Method D has been determined to be suitable for testing B and all blends of middle distillates and biodiesel. Work Item s – proposed revisions of this standard. NOTE 11—Subscripts 1 to x indicate the number of the ltration. NOTE 7—Membrane lters with a grid imprinted on their surface, may be used as control membrane lters for identication.

This allows the fuel to be used for additional analyses. See Test Methods D and D for means of determining particulate contamination in Specication D aviation turbine fuels and other similar aviation fuels.

No other units of measurement are included in this standard. Preparation of Apparatus and Sample Containers 8.

Samples containing biodiesel can result in partial dissolution or compromise of the membrane filters and give erroneous results. Allow 30 min for the membrane lters to come to equilibrium with room air temperature and humidity. 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.

The two membrane lters used for each individual test shall be identied by marking the petri dishes used to hold and transport the lters. 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. The information on the precision of this test method was developed with fuels ranging in particulate contamination from approximately 0.

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. Your comments will receive careful consideration at a meeting of the responsible technical committee, which you may attend.

Samples containing biodiesel can result in partial dissolution or compromise of the membrane filters and give erroneous results. This test method is suitable for all No. Because of this, take care to protect the sample from any external contamination.


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.

Results obtained when analyzing samples with volumes signicantly different than 1 L may have different precision values. The precision data were obtained by statistical examination of interlaboratory test results using fuels samples of approximately 1 L volume. 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.

Reagents and Materials 7. Signicance and Use 5. This test method used about a quarter of the volume used in the aviation fuel methods. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. D — 98 robin participants using both water aspirated and mechanical vacuum systems with vacuums ranging from 1 to kPa. 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.

See Guide D for a more detailed discussion of static electricity formation and discharge. Summary of Test Method 4.

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