Glass containers are preferred to facilitate a d62217 inspection of the contents and the container before and after lling. Air ionizers shall be replaced within one year of manufacture. The two membrane lters used for each individual test shall be identied by marking the petri dishes used to hold and transport the lters.

This test method is suitable for all No. Dry and reweigh the membrane lters as described in Record the nal control membrane lter mass and the nal test membrane lter mass to the nearest 0. See Guide D for a more detailed discussion of static electricity formation and discharge. NOTE 5—Small watch glasses, approximately 5 to 7 cm in diameter, have also been found suitable to support the membrane lters.

Asttm includes not only all of the fuel but also all rinsings of the interior of the container with ushing uid. Current edition approved Jan. For fuels containing little particulate materials, only one set of lters is required.

Where possible, the contents of the tank should be circulated or agitated before sampling, or the sampling performed shortly d627 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.

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. A superscript epsilon e indicates an editorial change since the last revision or reapproval. To facilitate handling, the membrane lters should rest on clean glass support rods, or watch glasses, in petri dish. 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.

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. 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 d617 to complete ltration in a reasonable time.

However, some fuels, d6127 to the quantity or nature of particulates, or both, may plug the membrane lter during ltration and require use of multiple successive ltrations.

Do not remove the plastic lm from the funnel opening until ready to start ltration. 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. Higher levels s6217 particulate contaminant can be measured, but are subject to uncertain precision.

Samples should preferentially be obtained dynamically from a sampling loop in a distribution line, or from the ushing line of a eld sampling kit. 6d217 Item s – proposed revisions of this standard. Keep the fuel sample ltrate separate from the solvent washings ltrate.

Allow 30 min for the membrane lters to come to equilibrium with room air temperature and humidity.

Maximum particulate levels are specied in several military fuel specications. 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.

Preparation of Membrane Filters asmt Install the funnel and secure with locking ring or spring clip. D — 98 exposure to fumes, the ltering procedure should be performed in a fume hood. Precision and Bias Maximum particulate levels are specified in several military fuel specifications. Because of this, take care to protect the sample from any external contamination.

D — 98 containers, their caps and petri dishes as described in 8. See Test Methods D and Asttm for means of determining particulate contamination in Specification D aviation turbine fuels and other similar aviation fuels. Weigh it, record the initial mass to the nearest 0. Your comments are invited either for revision of this standard or for additional standards and should be addressed to ASTM International Headquarters.

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.

With the vacuum applied, carefully separate the funnel from the lter base. D — 98 membrane set consists of a tared nylon test membrane and a tared nylon control membrane.

Link to Active This link will always route to the current Active version of the standard. NOTE 7—Membrane lters with a grid imprinted on their surface, may be used as control membrane lters for identication.

This test method is suitable for all Aetm.
