The pressurization device shall have good sealing performance and stable pressurization rate. Its flow rate shall be adjustable, to meet the requirements of the testing cylinder product standard for pressurization rate. 6.1.4 The connection between the pressure-bearing pipeline and the test device and measuring instrument shall have a good seal. Metal pipes shall be used for fixedly- installed pressure-bearing pipelines. A flexible connection that acts as a shock absorber can be a high-pressure hose. The pressure-bearing capacity of the pressure-bearing pipeline shall meet the requirements for the hydraulic burst pressure of gas cylinder. 6.2 Measuring instruments 6.2.1 Pressure measuring instrument 6.2.1.1 A pressure gauge and a pressure transmitter (or a digital pressure gauge capable of outputting pressure signals) shall be installed on the test apparatus. The pressure gauge is used to display test pressure in real time. The pressure transmitter (or digital pressure gauge that can output pressure signals) is used to collect pressure data. The installation position of pressure gauge and pressure transmitter (or digital pressure gauge that can output pressure signals) shall be such that the test pressure can be correctly displayed. 6.2.1.2 The range of the pressure gauge shall be 1.5~3 times the minimum burst pressure of the testing cylinder. The accuracy level shall not be lower than level 1.6. The range of the pressure transmitter (or digital pressure gauge capable of outputting pressure signals) shall be 1.5~3 times the minimum burst pressure of the testing cylinder. The accuracy level shall not be lower than level 0.5. 6.2.1.3 Pressure measuring instruments shall be verified or calibrated regularly.
