General - 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 semi-solid grease type (e.g., lubricated plug).
b. Combination soft and metal seats.

The inspection requirements pertain to examinations and testing by the manufacturer and any supplementary examinations that the purchaser may require at the valve manufacturer’s plant. The test requirements cover both required and optional pressure tests at the valve manufacturer’s
plant. The following tests and examinations are specified inthis standard:
a. Shell test.
b. Backseat test.
