scope:

This European Standard specifies the minimum requirements for the design, construction and testing during manufacture of transportable refillable welded steel Liquefied Petroleum Gas (LPG) cylinders, of water capacity from 0,5 l up to and including 150 l, exposed to ambient temperatures. This European Standard applies only to cylinders having a circular cross-section. The main technical changes are a widening of the range of materials permitted, reference to the latest ISO welding standards, the introduction of radioscopy as a permitted alternative to radiographic examination of welds, a reduction in the minimum required burst pressure from 50 bar to 35 bar and simplification of the marking requirements by reference to EN 14894.
