PROPOSAL TO ESTABLISH A TECHNICAL EXPERT GROUP TO SPECIFY THE REQUIREMENTS OF A UK QUALIFICATION SCHEME FOR SERVICE/REPAIR CENTRES OF SAFETY AND RELIEF VALVES MANUFACTURED TO THE REQUIREMENTS OF ISO 4126

What is it?:



The TEG is a group of experts having a background of Safety Valve manufacturing, service and repair. It will meet to initially discuss the issues currently being faced by manufacturers and end users of achieving a regulated system of safety valve service, maintenance testing and repair. If there is support for the idea, and subject to BVAA Board approval, the TEG will develop the requirements of a UK qualification scheme for Service/Repair Centres of Safety and Relief valves.

Why is it important?:



Safety and Relief valves need regular service and testing to ensure they are capable of performing when required to do so. In the USA the National Board offers the Certificate of Authorization and VR Stamp for the repair of pressure relief valves. Requirements are described in NB-514, accreditation of VR Repair Organizations.

Within the non-ASME community there is uncertainty as to what would define;

1. Competency for an approved 3rd party to repair and service safety and relief valves.
2. The capability of an approved 3rd party to assemble and test valves in compliance with ISO 4126.
