The degree of mixing atm on the type of transfer being made, the analytical test to be conducted and the characteristics of the sample. Loss of vapor normally associated with rise in temperature may also occur which could affect tests results for water, RVP, and density.
We are a non-profit group that run this website to share documents. Containers acceptable for samples to be tested immediately may not be acceptable for storage of sample. Calculate the average baseline water content to the nearest 0. D — 96 6. We need your help to maintenance this website.
ASTM D – 16e1 Standard Practice for Automatic Sampling of Petroleum and Petroleum Products
These categories vary greatly in severity depending on the type of analytical test to be conducted and the characteristics of the sample. This practice does not address how to sample crude at temperatures below the freezing point of water.
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. Care must be used when using cork stoppers.
The test liquid should contain no free water. Rubber stoppers should never be used. It is preferable to use a needle that will reach to the bottom ast the container.

If the composite is for multiple tanks, it must consist of proportional parts from each tank sampled. 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. A number in parentheses indicates the year of last reapproval. The following is a brief discussion of each category: Last previous edition approved in as D —96 20 —96 In the case of insertion mixers, each mixer must be reevaluated for any change in type of petroleum liquid, volume in the sample container, type of sample container, change in mixing conditions such as mixing speed or mixing time and increase in free water level.
A means of installing security seals should be provided. Consideration of closure type is important for samples where vapor loss will affect the test results. Second, the system must be shown to be effective or free of bias. Link to Active This link will always route to the current Active version of the standard.
Combining values from the two systems may result in non-conformance with the standard.
However, when such a sample is stored or transported in the extracting device, mixing is required. Sample Extractor Grab Volume. The sample in the one quart jar must then be returned to the sample container. Sample Mixing Methods 8. D — 96 3. Clear glass bottles atm be examined visually for cleanliness and allow wstm visual inspection of the sample for free water or solid impurities. The mixer may be an integral part of a stationary sample receiver or a stand-alone unit used for portable sample receivers.
ASTM D5854 – 96(2015)
If repeatability or system bias is not acceptable, identify and correct the problem and then proceed with re-testing. This practice does not cover sampling of electrical insulating oils and hydraulic fluids. A superscript supers cript epsilon e indicates an editorial change since the last revision or reapproval. Fill astn container to the selected level with petroleum liquid. A beaker may be used to add water to sample containers larger than 1 qt.
Publis Published hed October 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 axtm from external sources including weather.
Currentt editio Curren edition n approv approved ed June 1, Power mixing is also required when the sample has been transported or stored in either a primary or intermediate container. Therefore, samples to be composited should be submitted ast the laboratory along with a list of each tank and the volume represented by each sample.
First, there must be repeatability between the three test specimens. 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. Exercise care to prevent a rise in temperature that would cause liquid or foam to boil from the sample container. Please copy and paste this embed script to where you want to embed Embed Script.
The values stated in each system may not be exact equivalents; therefore, each system shall d554 used independently of the other.
Clear plastic bottles are atsm for samples sensitive to light.
