Scope

Main technical content: This document specifies the burning test process and safety assessment technical requirements for liquefied petroleum gas cylinders. This document is applicable to rechargeable steel cylinders with a nominal working pressure not exceeding 2.1 MPa, a nominal water volume not exceeding 150 L, a storage medium of liquefied petroleum gas, and an operating temperature not lower than -40 °C and not higher than 60 °C. By conducting a comparison of burning experiments on liquefied petroleum gas cylinders and setting different burning parameters (temperature, time, burning method, and residual liquid concentration), the effects of burning on the microstructure, performance, and safety of the cylinder materials are analyzed to obtain relevant experimental data and complete the recommended burning parameters table for liquefied petroleum gas cylinders. Based on a large amount of experimental data, a set of safety evaluation methods for the burning process is developed.
