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 refillable 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 comparative burning experiment on liquefied petroleum gas cylinders and setting different burning parameters (temperature, time, burning method, and residual liquid concentration), the impact of burning on the microstructure, performance, and safety of the cylinder material is determined, and relevant experimental data are obtained. A recommended burning parameter table for liquefied petroleum gas cylinders is also completed. On the basis of a large amount of experimental data, a set of safety evaluation methods for the burning process is developed.
