However, it is recognized that all sampling methods do not permit this nor do requirements to transport and store samples. These mixers can be used on a variety of different types and sizes of sample containers. The following annexes outline mixing procedure acceptance testing and present recommended forms for recording the results of such testing.
The treatment of samples from the time of collection until they are analyzed requires aatm and effort to maintain axtm compositional integrity. A change in one of the other conditions is then necessary.
D — 96 3. Calculate the average baseline water content to the nearest 0. If d554 or system bias is not acceptable, identify and correct the problem and then proceed with re-testing. Containers acceptable for samples to be tested immediately may not be acceptable for storage of sample. Link to Wstm This link will always route to the current Active version of the standard. This annex presents the calculation of sample preparation precision, together with a sample calculation.
We need your help! The degree of mixing depends on the type of transfer being made, the analytical test to be conducted and the characteristics of the sample.
ASTM D5854 – 96(2015)
If the composite is for multiple tanks, it must consist of proportional parts from each tank sampled. Please fill this form, we will try to respond as soon as possible. Loss of vapor normally associated with rise in temperature may also occur which could affect tests results for water, RVP, and density.
To prevent a boil-over, it may be necessary to place the sample 5d854 in an ice bath. PetroleumSafetyChemistryMaterialsNature. Some petroleum samples are affected by exposure to sunlight if clear glass is used.
A pressure gage should also be provided. In these cases, brown glass bottles may afford the necessary protection. Depending on the particular application, the results may be averaged arithmetically or on a volumetrically proportional basis according to the proportion of the total petroleum which the sample represents.
Power mixers may entrain air into the sample that could affect certain analytical tests. All equipment should be installed, operated, and maintained in a manner to minimize potential health and safety hazards.
A superscript supers cript epsilon e indicates an editorial change since the last ashm or reapproval. Publis Published hed October The mixer may be an integral part of a stationary sample receiver or a stand-alone unit used for portable sample receivers.
The following are general design and construction considerations for sample containers. Non-aerating or highspeed shear mixers are examples of d854 mixers. Clear glass bottles may be examined visually for cleanliness and allow for visual inspection of the sample for free water or solid impurities. Insertion mixers may also be of a circulating loop design where a suction port is inserted into the sample container and the sample is circulated externally by means of a pump through a static mixer and discharged back into the sample container through a dispersal system.
Before its use, each power mixer design and sample container combination must be tested and proven to be effective. Last previous edition approved in as D —96 20 —96 Clear plastic bottles are unsuitable for samples sensitive to light.
Care must be used when using cork stoppers.
ASTM D – 16e1 Standard Practice for Automatic Sampling of Petroleum and Petroleum Products
X5854, it is not necessary to wash new containers. Samples should not be mixed where the analytical tests to be conducted may be affected by air which could be induced by power mixing or shaking. Thank you for interesting in our services. Exercise care in the selection of container material as it could affect the test results obtained from the sample.
A number in parentheses indicates the year of last reapproval. Sample Extractor Grab Volume. This practice also provides additional specific information about sample container selection, preparation, and sample handling.
The petroleum liquid used in the acceptance tests should contain no free water. For analytical tests using volumetrics, non-aerating shear mixers should be used. This practice does not cover sampling of electrical insulating oils and hydraulic fluids. The following is a brief discussion of each category: Fill the container to the selected level with petroleum liquid. Handling and Mixing Samples c5854.
