Doplňujúce informácie
| 1. Scope | ||
|
1.1 This practice is used for sampling gas from a transformer gas space or from a gas-collector relay where the volume of gas available is small and will not permit the use of Practice D2759. 1.2 This practice covers sampling, using a gas-tight syringe as the sampling apparatus and container. 1.3 If the apparatus to be sampled is found to be under a negative pressure, the apparatus pressure should be raised by the addition of nitrogen gas until a positive pressure is obtained. 1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. 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. |
