This document specifies requirements for an experimental method to prove that representative samples of valve shells and their body ends, made in cast iron, steel or copper alloy materials, are designed to possess the required pressure containing capability, with an adequate margin of safety. This document is not applicable to valves designed on the basis of time dependent strength values (creep) or valves designed for pulsating pressure applications (fatigue). For valves in the scope of the European legislation for pressure equipment, the sole use of an experimental method is only permitted when the maximum allowable pressure at room temperature, PS, multiplied by the DN-number is less than 3 000 bar. This document is used to supplement the tabulation method EN 12516-1:2014+A1:2018, and the calculation method EN 12516-2:2014+A1:2021 without limit.
