5 Test method
5.1 Determination of methane, hydrogen, oxygen, carbon monoxide, carbon dioxide and ammonia components in coal-based synthetic natural gas shall be carried out in accordance with GB/T 33445. Other equivalent methods may be used to determine methane, hydrogen, oxygen, carbon monoxide, carbon
dioxide and ammonia components in coal-based synthetic natural gas for
vehicle, and the arbitration test method is GB/T 33445.
5.2 Determination of total sulfur content in coal-based synthetic natural gas shall be carried out in accordance with GB/T 33318. Other equivalent methods may be used to determine the total sulfur content in coal-based synthetic natural gas for vehicle, and the arbitration test method is GB/T 33318.
5.3 Determination of water dew point of coal-based synthetic natural gas shall be carried out in accordance with GB/T 17283. Other equivalent methods may be used to determine the water dew point of coal-based synthetic natural gas for vehicle, and the arbitration test method is GB/T 17283.
5.4 Determination of the total content of solid particles in coal-based synthetic natural gas for vehicle shall be carried out in accordance with GB/T 27893. Other equivalent methods may be used to determine the total content of solid particles in coal-based synthetic natural gas for vehicle; and when the measurement result is objectionable, the arbitration test method is GB/T 27893. The test is carried out after decompression by a decompression device that has no filter.
6 Sampling and test rules
6.1 Sampling
The sampling of coal-based synthetic natural gas for vehicle shall be carried out according to GB/T 13609; the influence of hydrogen embrittlement shall be fully considered, and the sampling container shall be carefully selected. 6.2 Test rules
6.2.1 All items in Table 1 of Chapter 4 are delivery test items.
6.2.2 Under the following circumstances, coal-based synthetic natural gas products shall be thoroughly tested in accordance with the technical
requirements in this Standard:
-- When it is first put into production;
-- In normal production, after regular or cumulative production;
