2. ACCEPTANCE
2.2. Sampling locations, frequency and gas quality control points for compliance with the requirements of this standard are established in agreement with the consumer. In this case, the frequency of monitoring according to the indicators in Table 1, 5-8, as well as the gas moisture dew point, should be at least once a month. It is allowed, by agreement with the consumer, not to determine the mass concentration of hydrogen sulfide in gas from fields that do not contain this impurity.
2.3. The results of periodic gas quality tests apply to the volume of gas passed through the pipeline during the period between this and subsequent tests.
2.4. If unsatisfactory test results are obtained for at least one of the quality indicators, repeat tests are carried out according to this indicator on a newly selected sample. The results of repeated tests are considered final and apply to the volume of gas that passed through the pipeline during the period between this and the previous test.
3. TEST METHODS
3.1. Determination of moisture dew point in gas - according to GOST 20060-83. Determination by other methods and instruments with the same measurement accuracy is allowed.
4. TRANSPORTATION
4.1. Gas is transported through gas pipelines through gas distribution stations and points. Natural flammable gas can be supplied to consumers directly from fields, gas processing plants, main gas pipelines and underground gas storage stations through gas distribution stations and points.
