Tests sstm then conducted to see if analytical water test results agree with the known baseline water plus the known water added without affecting density of the total mixture by loss of light ends. A means of installing security seals should be provided. Selection of Sample Mixing Method 9.
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.
ASTM D5854 – 96(2015)
Non-aerating or highspeed shear mixers are examples of insertion mixers. However, it is recognized that all sampling methods do not permit this nor do requirements to transport and store samples. A change in one of the other conditions is then necessary. This practice also provides additional specific information about sample container selection, preparation, and sample handling. Clear plastic bottles are unsuitable for samples sensitive to light.
PetroleumSafetyChemistryMaterialsNature. It is impossible to cover all petroleum sampling requirements and materials from which sample containers can be made. Second, the system must be shown to be effective or free of bias. Please help us to share our service with your friends. To add water to sample volumes less than 1 L, use a syringe. Fill the container to the selected level with petroleum liquid.
ASTM D – 16e1 Standard Practice for Automatic Sampling of Petroleum and Petroleum Products
This practice does not cover sampling of electrical insulating oils and hydraulic fluids. Power mixers may entrain air into the sample that could affect certain analytical tests. 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.
The following are general design and construction considerations for sample containers.
At intervals of 5 min, continue to draw sets of three test specimens for a total of 15 min mixing time. Other than ensuring the cleanliness, use of these containers presents no unusual concerns. Power mixing is also required when the sample has been transported or stored in either a primary 5d854 intermediate container. In these cases, brown glass bottles may afford the necessary protection. This is especially a consideration when using plastic for long term storage of certain petroleum products.
The mixer may be an integral part of a stationary sample receiver or a stand-alone unit used for portable sample receivers.
After 5 min and while the mixer is running, draw three test specimens. This part is applicable to all petroleum liquid sampling whether it be crude oil or refined products.
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. Samples should be protected during storage to prevent weathering or degradation from light, heat, or other potential detrimental conditions. Ashm analytical tests using volumetrics, non-aerating shear mixers should be used. The open end of the plastic tubing is placed in a clean container.
D — 96 3. Normally, it is not necessary to wash new containers.
This practice does not address how to sample crude at temperatures below the freezing point of water. We are a non-profit group that run this website to share documents. However, when such a sample is stored or transported in the extracting device, mixing is required.
Values in Column B are calculated from the larger of 0. The following is a brief discussion of each category: The method of compositing should be documented and care taken to preserve the integrity and representativeness of the composite sample. This annex presents the calculation of sample preparation precision, together with a sample calculation. Please copy and paste this embed script to where you want to embed Embed Script.
The treatment of samples from the time of collection until they are analyzed requires care and effort to maintain their compositional integrity. First, there must be repeatability between the three test specimens. Safety and Health Precautions 5. In most applications, it is not desirable or practical to wash these receivers using soap and water as FIG.
Exercise care to prevent a rise in temperature that would cause liquid or foam to boil from the sample container. To prevent a boil-over, it may be necessary to place the sample container in an ice bath.
