Power mixing is also required when the sample has been transported or stored in either a primary or intermediate container. The volume of test specimen D — 96 will therefore need to be adjusted accordingly, if the centrifuge or distillation methods are used.
Please fill this form, we will try to asttm as soon as possible. When a composite is required, it must consist of proportional parts from each zone if it is for a single tank. Size px x x x x This practice also provides additional specific information about sample container selection, preparation, and sample handling. Care must be used when using cork stoppers. Clear plastic bottles are unsuitable for samples sensitive to light.
ASTM D – 16e1 Standard Practice for Automatic Sampling of Petroleum and Petroleum Products
The following are general design and construction considerations for sample containers. The following is a brief discussion of each category: Sampler Acceptance Test Data. D — 96 FIG. Loss of vapor normally associated with rise in temperature may also occur which could affect tests results for water, RVP, and density. In most applications, it is not desirable or practical to wash these receivers using soap and water f5854 FIG. At intervals of 5 min, continue to draw sets of three test specimens for a total of 15 min mixing time.
Historical Version s – view previous versions of standard Translated Version s: Some petroleum samples are affected by exposure to sunlight if clear glass is used. Thank you for interesting in our services. If formation water is used, the sediment and salt content must be determined.
A change in one of the other conditions is then necessary. The following annexes outline mixing procedure acceptance testing and present recommended forms for recording the results of such testing. We are a non-profit group that run this website to share documents. All equipment should be installed, operated, asgm maintained in a manner to minimize potential health and safety hazards. ICS Number Code Calculate the average water content to the nearest 0.
Please copy and paste this embed script to where you want to embed Embed Script. To add water to sample volumes less than 1 L, use a syringe. A superscript supers cript epsilon e indicates an editorial change since the last revision or reapproval. Second, the system must be shown to be effective or free of bias. A means of installing security seals aatm be provided.
Historical Version s – view previous versions of standard. It is preferable to use a needle that will reach to the bottom of the container. Samples should not be mixed where the d58554 tests to be conducted may be affected by air which could be induced by power mixing or shaking. Normally, additional mixing is of no value and often produces diminishing results due to a reduction in viscosity from an increase in temperature.
These mixers can be used on a variety of different types and sizes of sample containers. A pressure gage should also be provided.
Please help us to share our service with your friends. Other water test methods are acceptable.
It is impossible to cover all petroleum sampling requirements and materials from which sample containers can be made. Therefore, samples to be composited should be submitted to the laboratory along with a list of each tank and the volume represented by each sample. Before its use, each power mixer d5584 and sample container combination axtm be tested and proven to be effective.
Values in Column B are calculated from the larger of 0. Exercise care also to ensure that samples containing free or entrained water are not corrosive to the metal. PetroleumSafetyChemistryMaterialsNature. This annex presents the calculation of sample preparation precision, together with a sample calculation.
Each use of intermediate containers increases the potential for loss of light hydrocarbons, loss of water due to clingage, or inefficient mixing and contamination of the sample from external sources including weather. Normally, it is not necessary to wash new containers. Publis Published hed October Caps should provide a vapor tight seal. However, it is recognized that all sampling methods do not permit this nor do requirements to transport and store samples. Use of sludge solvents to remove all traces of sediments and sludge e5854 be necessary.
Sample Mixing Methods 8. 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 satm by means of a pump through a static mixer and discharged back into the sample container through a satm system.
Handling and Mixing Samples 7. Exercise care to prevent a rise asttm temperature that would cause liquid or foam to boil from the sample container. Non-aerating or highspeed shear mixers are examples of insertion mixers. We need your help!
