EN ISO 10460 – Welded Carbon Steel Cylinders Periodic Inspection and Testing.
This standard is primarily intended for use with cylinders containing industrial gases other than liquefied petroleum gas (LPG) but may also be applicable to LPG. This standard is considered to be more onerous than the dedicated LPG cylinder inspection standard as the gases contained in these cylinders can often be toxic, flammable, corrosive or may cause damage to the environment if released into the atmosphere.
This document specifies the requirements for the periodic inspection and testing of welded carbon steel cylinders with a water capacity from 0.5 Ltrs to 150 Ltrs and also applies as far as is practical to cylinders of less than 0.5 Ltrs and greater than 150 Ltrs up to 450 Ltrs. However, this standard does not apply to the periodic inspection and testing of Acetylene cylinders or composite (full wrapped or hoop-wrapped ) cylinders.
Safe Gas Cylinders use the hydraulic method of pressure testing to ensure the cylinder is fit for further service. The retest frequency of the cylinder is determined by the gas service and this detailed in the ADR book , P200 packing instructions.
