ASME A112.19.5:2005 pdf free download.Trim for Water-ClosetBowls, Tanks,and Urinals.
ASME A112.19.5 establishes criteria for those items of trim for water-closet bowls, tanks, and urinals known as spuds, locknuts for spuds, flush valves, and flush elbows. Requirements for fill valves (bailcocks) are defined in ANS1/ASSE 1002.
This Standard does not address the compatibility of materials. Nothing stated herein shall preclude the production of special design flush valves with unique nonstandard features for use in low-consumption plumbing fixtures.
1.2 Units of Measurement
Values are generally stated in U.S. Customary units and International System of Units (SI). US. Customary units shall be considered as the standard.
13 Reference Standards
The following documents form a part of this Standard to the extent specified herein. The latest issue shall apply.

1.4 Definitions
flush valve flapper: an elastomeric flush valve component that combines in one piece a pair of lever arms, a valve seat sealing surface, and sometimes a float.
5.1.3 Replacement flush valve flappers shall have labels that comply with para. 5.5.
5.2 Flush Valve Marking — Manufacturer’s Name or Trademark
Flush valves shall be niarked with the manufacturers name or registered trademark, or, in case of private labeling, of the customer for whom the unit was manufactured. This mark shall be legible, readily identified, and permanently affixed.
5.3 Service
All water-closet tanks shall have a permanent, legible label with the telephone number for a service department that can inform a caller of the correct replacement components for the water-closet tank and the source of those components. The suggested language for the label is, “To service tank components, call xxx-xxx-xxxx” (where the x’s represent the service telephone number). The label shall also include the manufacturer’s part number of the flush valve seal.
5.4 Marking Replaceable Components of Flush
Valves Installed as Original Equipment In Water- Closet Tanks
When flush valve seals and flappers are replaced, it could change the water-closet tank water consumption. Therefore, it is necessary for manufacturers of water- closet tanks to provide service information about installed flush valves. Every water-closet tank shall be permanently marked or permanently labeled with the appropriate information in para. 5.4.1, 5.4.2, or 5.4.3.
5.4.1 Standard Flush Valve Flappers. All water-closet tanks fitted with a 2 in. flush valve utilizing a standard, buoyant flapper flush valve seal shall have a label that reads, “Use Only Standard 2 in. Replacement Flapper.”
5.4.2 Early Closure Flush Valves With Adjustable Flappers. All water-closet tanks fitted with a 2 in. flush valve utilizing an early closure flush valve seal, in which the flush valve seal is adjustable to control the closing water level in the tank, shall have a label as stated in para.
5.4.2.1.
5.4.2.1 Early Closure lime and Distance Numbers. Two early closure numbers (as defined in para. 5.4.2.1.1) shall be marked on the label. The label shall read, ‘FUse only EC-Txx or EC-Dyy Replacement Flush Valve Seals,” whew the xx’s and yy’s represent the early closure time and distance numbers.
5.4.2.1.1 Early Closure Numbers. Early closure flush valves in which the flush valve seal is adjustable to control the closing water level arc dependent on either a time delay or a distance that the water level drops to control the point at which the flush valve closes.
