ASME A112.19.3:2008 pdf download.Stainless steel plumbing fixtures.

Mirror finish - a highly reflective finish with no visible polishing lines.

Rim - the unobstructed open edge of a fixture.

Satin finish — a surface with a soft sheen consisting of fine, regular polish lines in a uniform pattern.

Urinal — a fixture that receives only liquid body waste and conveys the waste through a trap Into a drainage

system,

Vertical wrface - a surface forming an angle with the hoiizontai of 45 to 90°.

Water closet — a fixture with a water-containing receptor that receives liquid and solid body waste and on

actuation conveys the waste through an exposed integral trap into a drainage system.

4 General requirements

4.1 Materials

Wth the exception of laboratory sinks, which shall be made of type 316 stainless steel alloy, stainless steel

plumbing fixtures shall be made of type 201. 202. 301, 302, 304, 316, or 430 stainless steel alloys.

Note: These stowless steel types are specified in ASTM A 240/A 240M.

4.2 Stainless steel thickness

4.2.1 Lavatories and sinks

4.2.1.1 General

The thickness of stainless steel sheet lot lavatories and kitchen, bar, laboratory, laundry, and utility sinks

shall comply with Clause 4.2.1.2 (before drawing) or 4.2.1.3 (after drawing).

4.2.1.2 Before drawing

The minimum thickness shall be based on bowl depth as specified in Table 1.

4.2.1.3 After drawing

The minimum thickness after fabrication shall be as follows:

(a) vertical surfaces: 0.559 mm (0.022 in);

(b) corners: 0.508 mm (0.020 in); and

(c) horizontal surfaces: 0.635 mm (0.025 in).

For Items (a) and (b), the thickness shall be determined by taking the average of six measurements of surface or

corner thickness. For Item (C), thickness shall be determined by taking the average of three measurements from the bottom of the fixture and three from the flat surfaces of the flange.

4.2.2 Other fixtures

The thickness of stainless steel sheet for fixtures not specified in Clause 4.2.1.1 shall be determined in

accordance with Clause 4.2.1.3.
