Method for hydraulic burst test of gas cylinder
1 Scope
This document specifies the methods for hydraulic burst test of gas cylinder and the basic requirements for test devices.
This document is applicable to the hydraulic burst test of gas cylinder with a nominal working pressure not greater than 70 MPa (gauge pressure, the same below).
2 Normative references

3 Terms and definitions
For the purposes of this document, the terms and definitions given in GB/T 13005 and the following apply.
3.1
testing cylinder
gas cylinders to be tested or under test
4 Principle
In the hydraulic burst test of gas cylinder, gradually increase the pressure in the testing cylinder until it bursts at the specified pressurization rate. The yield pressure (when required), hydraulic burst pressure and quantity of water pressed of the testing cylinder shall be tested, the volume deformation value and volume deformation rate of the testing cylinder (when required) shall be calculated, and the crack characteristics and the crack position of the testing cylinder shall be checked.
