However, gas-saturated samples will begin to release gases bubbles soon after sampling. To minimizewaste and potential spills a length of 60 cm 24 in. Samples can beobtained safely. Extreme care should be used in performing this procedure.

Attach the plastic tube tothe syringe as shown in Fig. Preparation for Sampling 6. Thank you for visiting our website and your interest in our free products and services.

Last previous edition D — Test Method DTable 1,provides coefficients of variation for different gas-in-oil analy-sis from samples collected in the three containers recom-mended in this practice. Collecting Samples Using Syringe 8.

One of twoprocedures may then be used to prepare the sample outlet. All materials on our website are shared by users. A large variancefrom normal should be considered when evaluating the testresults obtained when the syringe conditioning was c3613 used.

Once the container is full, install thecap immediately. Wipe the inside of the valve and threads witha clean lint free cloth.

Wipe the inside of the valve and threads with a clean lint free cloth. This should involve a volumeof air equivalent to at least 55 changes of the cylinder volumeduring the 15 min period of drying. The samples should notbe stored. However, gas-saturated samples will begin to release gases bubbles soon after sampling.

Samples can be obtained safely. To the running of this website, we need your help to support us. Open the lower valve on the steel cylinder.

Transformer Oil Gas Analyser (TOGA)

Flush the valve at installed sample adapter, flushing at least one more quart of fluid into the flush oil container before collecting sample. If the slug moves away from the electrical apparatus, d363 positive pressure exists.

Package the filled d36613 as soon as possible to protect the sample from light. With all three valves openand the cylinder held in a vertical position see Fig. Sampling should be discontinued. The tubing should not be reused. Asuperscript epsilon e indicates an editorial change since the last revision or reapproval.

Wipe the inside of the valve and threads with a clean lint-free cloth. Cleaning of Apparatus 5. It isdesirable that stainless steel cylinders be evacuated and sealedafter cleaning. While observing the slug of insulating fluid, slowly crack the sample outlet valve open.

ASTM D for Sampling Insulating Liquids for Gas Analysis and Water Analysis – YONGRUN

The filled syringe should contain no air. Perform this condition procedure onemore time. The air may be dried bypassing the air through two drying towers in series, each toweris at least 9 cm diameter atm 28 cm in height. We are nonprofit website to share and download documents.

Connectthe oil-resistant tubing to the lower valve port on the steelcylinder and connect a short piece approximately 60 cm 24in. If the slug moves towardsthe electrical apparatus, atsm negative pressure exists. These cylindershave the disadvantage of not allowing visual inspection of theinterior of the cylinder. Test Method D, Table e3613, provides coefficients of variation for different gas-in-oil analysis from samples collected in the three containers recommended in this practice.

Samples should be forwardedto the laboratory as quickly as possible.

Immediately close the port into the syringe Fig. Install the drain valve security plug.

If any sound is heard,the cylinder should be drained and the sampling repeated. Syringes having precision ground barrels andpistons are preferred. Syringe Valve Piston Gases Materials. D3631 not release any evolvedgases bubbles since these gases must be included in thedissolved gas analysis.
