Minor 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 poiish 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 surface — a surface forming an angle with the horizontal of 45 to 9W.
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
With 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 stoirdes.s steel afloy twes are specified Wi AS TM 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 for 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 fIat 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.
4.3 Tolerances
Unless otherwise specified in this Standard, the tolerance on dimensions of 200 mm (8 in) and greater shall be t 3%. The tolerance on dimensions less than 200 mm (8 in) shall be ± 5%.
In this Standard, dimensions specified as “minimum” or “maximum” shall not be reduced below the specified minimum or increased above the specified maximum by application of a tolerance. If a dimensional range is spec ified and the word “minimum” or “maximum” does not appear, the upper and lower limits shall not be considered critical and the appropriate tolerance shall apply.
