If sampling is for the Samples for Laboratory Analysis5 precise astmm of volatility, use Practice D in D Test Method for Oxidation Stability axtm Gasoline conjunction with this practice. A summary of the manual sampling procedures and their D Practices for Sampling Electrical Insulating Liquids6 applications is presented in Table 1.

Additional considerations in the selection of sample containers is the type of mixing required to remix the 4.

Summary of Practice contents before transferring astk sample from the container and 4. To facilitate the discussion on proper handling and semi-liquid or solid state from tanks, pipelines, drums, barrels, mixing of samples, sample containers are referred to as either cans, tubes, bags, kettles and open-discharge streams. It ad- primary or intermediate containers. Regardless of the type of dresses, in detail, the various factors which need to be sample container used, the sample d44057 should be large considered in obtaining a representative sample.

The astmm capacity is sample, the types of sample containers to be used and any required for thermal expansion of the sample and enhances special instructions required for special materials to be sample mixing. Test Method D can provide additional guidance. Significance and Use 6. A series of spot samples may be combined to create 6. Bottles of this type 5.

Therefore, the sampling operation should be wash, the container should be washed with a strong soap conducted before innage gaging, the associated temperature solution, rinsed thoroughly with tap water, and given a final determination, and any f4057 similar activity that could disturb rinse using distilled water.

Dry the container either by passing the tank contents. When sampling operation, the order of precedence for sampling dry, stopper or cap the container immediately.

Normally, it is should start from the top and work downward, according to the not necessary to wash new containers. In most applications, it is not desirable or 7. It is good 6. When the respective tests are performed on individual that have stratified to ensure that a representative sample is samples, which is the recommended procedure, the test results available for transfer to an intermediate container or the are averaged generally.

This is especially critical when remixing 7. In order for such a composite eters, should not be lowered into or suspended in a compart- tank sample to be representative of the material contained in ment or tank that is being filled, or immediately after cessation the various tanks, the quantity from the individual samples of pumping.

The method ashm compositing should be the electrostatic charge. In order to reduce the potential for documented and care taken to preserve the integrity of the static charge, nylon or polyester rope, cords, or clothing should samples. It is recommended that a portion of each tank sample not be used.

Special Instructions for Specific Materials 7. Refer to Practice D for guidance on 9. Tank samples of crude oil and residual oils 7. The running sample or the composite of the upper, before capping. All other samples shall be capped immediately middle, and lower sample may not represent the concentration and taken to the laboratory.

The loss of light sludge. The bottom is often covered by pools of free product clarity. The more transfers between containers, the water or water emulsion impounded by layers of sludge or greater the likelihood one or both of these problems adtm occur. See Practice D for additional information concerning the 9. D is recommended whenever samples of these materials 7.

However, tank samples should be maintained in a closed container in order to samples may be used when agreed to by all parties to the prevent loss of light components. Samples should be protected transaction.

Tank sampling, in accordance with the procedures another container or test vessel, the sample must be thoroughly outlined in Section 13, is acceptable under the conditions mixed in accordance with the type of material and appropriate covered in 5. Exercise care to ensure mixing does not alter industrial aromatic hydrocarbons benzene, toluene, xylene, the components within the sample, for example, loss of light and solvent naphthasproceed in accordance with Sections ends.

See Practice D for more asgm instructions. See Annex A1 for details. However, it is presumed that the 9. Annex A1 provides qts by mixing equal parts of the upper and lower samples. Prepare a composite sample of at d4075 1 L 1 qt by a temperature of 0 to 4.
