This standard covers inspection, examination, supplementary examinations, and pressure test requirements for resilient-seated, nonmetallic-seated (e.g., ceramic), and metal-to-metal-seated valves of the gate, globe, plug, ball, check, and butterfly types. Resilient seats are considered to be: a) soft seats, both solid and semisolid grease type (e.g., lubricated plug); b) combination soft and metal seats (e.g., laminated seat rings); c) any other type of seat material designed to meet resilient seat leakage rates as specified in Table 5.
