PetroleumSafetyChemistryMaterialsNature. Power mixing is also required when the sample has been transported or stored in either a primary or intermediate container. Please copy and paste zstm embed script to where you want to embed Embed Script. These categories vary greatly in severity depending on the type of analytical test to be conducted and the characteristics of the sample. When a composite is required, it must consist of proportional parts from each zone if it is for a single tank. For analytical tests using volumetrics, non-aerating shear mixers should be used.

Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided d58554 part of the standard. Last previous edition approved in as D —96 20 —96 Loss of vapor normally associated with rise in temperature may also occur which could affect tests results for water, RVP, and density. It is impossible to cover all petroleum sampling requirements and materials from which sample containers can be made.
The sample in the one quart jar must then be returned to the sample container. A means of installing security seals should be provided. In these cases, brown glass bottles may afford the necessary protection. These systems need to be evaluated at installation and reevaluated with changes in petroleum liquid, increase in free water concentration, or minimum and maximum sample volume.
ICS Number Code Thank you for interesting in our services. We need your help to maintenance this asrm. Caps should provide a vapor tight seal. System Proving Performance Acceptance Tests. If the composite is for multiple tanks, it must consist of proportional parts from each tank sampled.
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. Please fill this form, we will try to respond as soon as possible.
When dry, stopper or cap the container immediately.
ASTM D – 16e1 Standard Practice for Automatic Sampling of Petroleum and Petroleum Products
In most applications, it is not desirable or practical to wash these receivers using soap and water as FIG. Internally epoxy-lined tin cans may have residual contamination and precaution should be taken to ensure its removal.
Calculate the average water content to the nearest 0. Currentt editio Curren zstm n approv approved ed June 1, This practice does not cover sampling of electrical insulating oils and hydraulic fluids. A change in one of the other conditions is then necessary.
The method of compositing should be documented and care taken to preserve the integrity and representativeness of the composite sample. 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.
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.
This part is applicable to all petroleum liquid sampling whether it be crude oil or refined products. This practice does not address how to sample crude at temperatures below the freezing point of water.
Calculate the average baseline water content to the nearest 0. This annex presents the calculation of sample preparation precision, together with a sample calculation.
The following annexes outline mixing procedure acceptance testing and present recommended forms for recording the results of such testing. Those who handle petroleum samples must be familiar with these regulations in addition to their own company policies and procedures.
Values in Column B are calculated from the larger of 0. 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. Performance Criteria for Portable Sampling Units.
Publis Published hed October Normally, additional mixing is of no value and often produces diminishing results due to a reduction in viscosity from an increase in temperature. However, it is recognized that all sampling methods do not permit this nor do requirements to transport and store samples. D — 96 3. When analytical tests are performed on individual samples, which is the recommended procedure, the test results are generally averaged.
Consideration wstm closure type is important for samples where vapor loss will affect the test results. Sample Mixing Methods 8.
