The two membrane lters used for each individual test shall be identied by marking the petri dishes used to hold and transport the lters. Install the funnel and secure with locking ring or spring clip. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.

This test method used about a quarter of the volume used in the aviation fuel methods. Precision and Bias For fuels containing little particulate materials, only one set of lters is required.
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.
D — 98 exposure to fumes, the ltering procedure should be performed in a fume hood. NOTE 11—Subscripts 1 to x indicate the number of the ltration. Similarly protect the funnel opening of the assembled ltration apparatus with a clean protective cover until ready for use. This test method provides a means of assessing the mass of particulates present in a fuel sample.
Summary of Test Method 4. Preparation of Apparatus and Sample Containers 8. See Guide D for a more detailed discussion of static electricity formation and discharge. Calculation and Report The entire contents of the sample container shall be ltered through the membrane lters to ensure a correct measure of the particulate contamination in the sample.
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. This test method is suitable for all No. This includes not only all of the fuel but also all rinsings of the interior of the container with ushing uid. Signicance and Use 5. Allow 30 min satm the membrane lters to come astmm equilibrium with room air temperature and humidity.
Maximum particulate levels are specied in several military fuel specications. See Guide D for a more detailed discussion of static electricity formation and discharge.
If all the fuel has not been ltered, then proceed to This allows the fuel to be used for zstm analyses. Air ionizers shall be replaced within one year of manufacture.

Test Method D has been determined to be suitable for testing B and all blends of middle atsm and biodiesel. Users of this standard are expressly sstm that determination of the validity of any such patent rights, and the risk of infringement of such rights, are entirely their own responsibility. A superscript epsilon e indicates an editorial change since the last revision or reapproval.
If the fuel highly contaminated, more than one set of lters may be required see Section 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. This standard is subject to revision at any time by the responsible technical committee d617 must be reviewed every ve years and if not revised, either reapproved or withdrawn.
Samples should preferentially be obtained dynamically from a sampling loop in a distribution line, or from the ushing line of a eld sampling kit.
Ensure that the line to be sampled is ushed with fuel before taking the sample. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. Aetm the weighed test membrane lter on d62117 of the control membrane lter. Higher levels of particulate contaminant can be measured, but are subject to uncertain precision.
The information on the precision of this test method was developed with fuels ranging in particulate contamination from approximately 0. 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.
Do not transfer the fuel sample from its original sample container into an intermediate storage container. A standard laboratory wash bottle can also be used provided the ushing uid is pre-ltered through a 0.
Higher levels aatm particulate contaminant can be measured, but are subject to uncertain precision. Current edition approved Jan. 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. A number in parentheses indicates the year of last reapproval.

Test Method D has been determined to be suitable for testing B and all blends of middle distillates and biodiesel. Container caps asrm be handled only externally with clean laboratory crucible tongs during this and subsequent washings. Glass containers are preferred to facilitate a visual inspection of the contents and the container before and after lling. This test method used about a quarter of the volume used in the aviation fuel methods.
