To prevent asgm boil-over, it may be necessary to place the sample container in an ice bath. The volume of test specimen D — 96 will therefore need to be adjusted accordingly, if the centrifuge or distillation methods are used. However, when such a sample is stored or transported in the extracting device, mixing is required. If the composite is for multiple tanks, it must consist of proportional parts from each tank sampled. 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.
Exercise care sstm prevent a rise in temperature that would cause liquid or foam to boil from the sample container. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard.
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. In astmm cases, brown glass bottles may afford the necessary protection. Other water test methods are acceptable. Please help us to share our service with your friends. If repeatability or system bias is not acceptable, identify and correct the problem and then proceed with re-testing. To add water to sample volumes less than 1 L, use a syringe.
PetroleumSafetyChemistryMaterialsNature. The test liquid should contain no free water. After 5 atm and while the mixer is running, draw three test specimens. This practice gives e5854 on the types of containers that have been found satisfactory for tests to determine water separation, copper corrosion, electrical conductivity, thermal stability, lubricity, and trace metal content. Consideration of closure type is important for samples where vapor loss will affect the test results.
Clear glass bottles may be examined visually for cleanliness and allow for visual inspection of the sample for free water or solid impurities. Those asfm handle petroleum samples must be familiar with these regulations in addition to their own company policies and procedures. A change in one of the axtm conditions is then necessary. When a composite is required, it must consist of proportional parts from each zone if it is for a single tank.
Second, the system must be shown to be effective or free of bias.
For analytical tests using volumetrics, non-aerating shear mixers should be used. Exercise care in the selection of container material as it could affect the test results obtained from the sample.
ICS Number Code Tests are 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. Currentt editio Curren edition n approv approved ed June 1, Prior to further use, reusable containers such as cans and bottles should be rinsed with a suitable solvent. A superscript supers cript epsilon e indicates an editorial change since the last revision or reapproval.
Normally, it is not necessary to wash new containers. Sample Extractor Grab Volume. D — 96 6. This is especially a consideration when using plastic for long term storage of certain petroleum products.
ASTM D5854 – 96(2015)
Loss of vapor normally associated with rise in temperature may also occur which could affect tests results for water, RVP, and density. Publis Published hed October D — 96 3. The suggested mixing time for constant speed circulation mixers is 5 min. These mixers can be used on a variety of different types and sizes of sample containers. Exercise care also to ensure that samples containing free or entrained water are not corrosive to the metal.
We need your help! This practice also provides additional specific information about sample container selection, preparation, and sample handling. The method of compositing should be documented and care taken to preserve the integrity and representativeness of the composite sample. We need your help to maintenance this website.
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. This practice does zstm cover sampling of electrical insulating oils and hydraulic fluids.
Combining values from the two systems may result in non-conformance with the standard. Sco Scope pe 1.

The sample in the one quart jar must then be returned to the sample container. 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. Sampler Acceptance Test Data. This practice does d5584 address d58554 to sample crude at temperatures below the freezing point of water.
