BS EN 764-4 is a European standard that specifies the requirements, under the regime of the EU Directive 97/23/EC on Pressure Equipment (PED), for the establishment of the technical delivery conditions in the form of:
for metallic materials for pressure equipment in all product forms. BS EN 764-4 was developed predominantly on the basis of steel, nickel and nickel-based materials. However, application to other materials is not restricted but should consider specific aspects relevant to the material concerned.
Note: Welding consumables are not covered by BS EN 764-4.
BS EN 764-4 on technical delivery conditions for metallic materials is useful for:
Technical delivery conditions for materials for pressure equipment shall describe the material with its specific properties and shall at least contain clauses for scope, normative references, requirements, testing and inspection and marking and restriction on application where necessary with a distinction between mandatory and optional requirements.
BS EN 764-4 provides its users with guidelines for test procedures and inspection for the pressure equipment vessels and materials. Using BS EN 764-4 guidelines ensures specification approvals, helps asses the condition of goods and enables smooth techincal documentation.
