ASME A112.18.1:2012 pdf download.Plumbing supply fittings.
Primary outlet — the outlet from a supply fitting on the discharge side of a valve through which water will discharge unless diverted to a secondary outlet.
Secondary outlet - an outlet from a supply fitting on the discharge side of a valve, other than the primary outlet, through which water can be discharged.
Permanent mark or label — a mark or label that is intended to remain in place for the lifetime of the fitting under conditions of normal use.
PhysIcal vapour deposition (PVD) — a family of coating processes in which the surface layer is formed by the deposition of individual atoms or molecules.
Note: In P1Do material is vaporized from a solei or liquid source, transported through a low-pressure gaseous or plasma tnvsironment, and condensed on a substiote surface.
Potable water — water that Is satisfactory for drinking and for culinary and domestic purposes. Note: Potable vaIer meets the requirements of the health authority having jumdictior.
Pressure
Flowing pressure - the pressure in the piping upstream of an open fitting or accessory. Supply pressure - the static water pressure in the fitting supply piping.
Pressure envelope — the outside part of a supply fitting that withstands and contains the water pressure.
Push-fit fitting — a mechanical fitting that joins pipes or tubes and achieves a seal by pushing by hand the mating pipe or tube into the fitting.
Note: The fitting con be removable or non-removable.
Rigid waterway — a cross-section of a waterway that can transmit a bending load to the body of a fitting.
Seal — a component or other portion of a fitting that prevents water leakage.
Seat disc - - a disc or washer that provides a watertight joint when compressed against the seat.
Servke conditions 1 (SC.1) — the coated surfaces of concealed fittings and concealed parts of exposed fittings.
Service conditions 2 (SC-2) — the coated signilicant surfaces of exposed fittings and exposed parts of concealed fittings.
Shank - the rigid threaded portion of a supply fitting that extends below the mounting surface and has a means for connecting to the supply piping.
Shower head — an accessory to a supply fitting for spraying water onto a bather, typically from an overhead position
Significant surface — an exposed surface that, if blemished, spoils the appearance or affects the performance of a fitting.
Secondary outlet - an outlet from a supply fitting on the discharge side of a valve, other than the primary outlet, through which water can be discharged.
Permanent mark or label — a mark or label that is intended to remain in place for the lifetime of the fitting under conditions of normal use.
