A large variancefrom normal should be considered when evaluating the testresults obtained when the syringe conditioning was not used. To minimizewaste and potential spills a length of 60 cm 24 in. We Need Your Support. With all three valves openand the cylinder held in a vertical position see Fig. Epidemiology, pathogenesis, and clinical manifestations of Ebola and Marburg virus disease. However, gas-saturated samples will begin to release gases bubbles soon after sampling.
This should involve a volumeof air equivalent to at least 55 changes of the cylinder volumeduring the 15 min period of drying. Last previous edition D — Extreme care should be used in performing this procedure.
Attach the plastic tube tothe syringe atsm shown in Fig. Install the drain valve security plug.
Wipethe inside of the valve and threads with a clean lint-free cloth. Once the container is full, install thecap immediately. Install the drain valve security plug.
Transformer Oil Gas Analyser (TOGA)
Remove the sample adapter if used, andreinstall the security plug with a non-hardening thread sealant. 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.
One of twoprocedures may then be used to d6313 the sample outlet. Wipe the inside of the valve and threads with a clean lint free cloth. The tubing ast not be reused. Preparation for Sampling 6. Samples can beobtained safely.

The air may be dried bypassing asttm air through two drying towers in series, each toweris at least 9 cm diameter and 28 cm in height. Perform this condition procedure onemore time.
Attach oil-resistant tubing to the sample port on the drain valve and flush at least one more quart of fluid into the flush-oil container before collecting the fluid in the sample container.
Cleaning thetubing should be considered impractical.
Remove the security pipe plug fromthe drain valve. Originallypublished as D — Immediately close the port into the syringe Fig. Syringe Valve Piston Gases Materials.
Test Method D, Table 1, provides coefficients of variation for different gas-in-oil analysis from samples collected in the three containers recommended in this practice. Samples can be obtained safely. d36133
Remove the security pipe plug from the drain valve. Package the filled syringe as soon as possible to protect the sample from light. Thank you for visiting our website and your interest in our free products and services. Ethics for managements consultans. When thedrying period has expired, syringe pistons shall be placed intheir barrels, valves closed; stainless steel cylinder valvesshould be closed; or cans sealed with their screw cap. Drain at least 1. See Test Methods D for further details about generalcleaning requirements.
However, gas-saturated samples will begin to release gases bubbles soon after sampling. Convenient cardboard cartons for storing and trans-porting syringes can be obtained. While observing the slug of insulating fluid, slowly crack the sample outlet valve open.
The samples should notbe stored. Chalmers The Components of Content.
ASTM D for Sampling Insulating Liquids for Gas Analysis and Water Analysis – YONGRUN
Immediately close the port to thesyringe Fig. Do not release any evolvedgases bubbles since these gases must be included in thedissolved gas analysis. Samples should be forwardedto the laboratory as quickly as possible. Take extreme caution when samples are drawn from electrical apparatus having a small volume of insulating fluid.
Sampling should be discontinued. Asuperscript epsilon e indicates an editorial change since the last revision or reapproval.
If you have any questions about copyright issues, please report us to resolve them. Do not pull thepiston manually since this can result in bubble formation. Do not allow the oil to be exposed tosunlight. The filled syringe should contain no air.
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. Slowly depress the syringepiston until all the oil is evacuated from the syringe completing FIG. A number in parentheses indicates the year of last reapproval.
