Intended to assist valve users and manufacturers achieve consistent and improved quality valves, and to eliminate the proliferation of valve test specifications in current use. This is a 'stand alone' document that is applicable to a wide range of valve ratings and sizes and can be used to entirely replace testing requirements in national standards such as API 6D, BS 6755 Part 1, and company specifications. Exceeds in scope and detail the requirements of national valve standards. Provides a potential basis for future CEN and ISO valve testing standards to meet the demanding requirements of the energy, process, oil and gas industries and provide the widest benefit to both users and manufacturers of valves.
