Valves. Shell design strength - Experimental method1 Scope This standard 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 standard is not applicable to valves designed on the basis of time dependent strength values (creep) or valves designed for pulsating pressure

the procedure for pre-treatment

BS 4479-9 is the second part of the BS 4479 gives recommendations for design features to be followed in the application of coatings by low pressure or vacuum deposition to various substrates

Test method comparison tables are included in Annex A to assist in selecting the appropriate measurement method(s)
