Qualification Procedure for Acetylene cylinder Design

This publication defines test equipment and procedures that are applicable for testing DOT and TC acetylene cylinders having a marked service pressure of 250 psi (1723 kPa).2These four tests in 5.1 through 5.4 are required to be conducted when there is a new cylinder design or a design change in the filler or a change in process. These tests shall be conducted before starting quantity production and introduction of a specific cylinder model into service. Cylinders shall pass all tests. NOTE—DOT regulations do not define what constitutes a design change; whereas, TC regulations define the criteria for acylinder design change in CSA B339 [1, 2].Cylinders to be tested shall be selected from a pilot production run of cylinders to permit the use of planned production equipment and procedures. Cylinders to be tested shall be of those produced in an actual production operation. Test cylinders are to be complete and of a quality for service including shell, filler, solvent, valve, core hole packing, PRDs, and painting. Cylinders used in any of these tests shall be scrapped.
