ASME A112.19.1-2008 pdf free download.Enamelled cast iron and enamelled steel plumbing fixtures.
Small speck — a speck whose largest dimension is greater than 0.25 mm (0.010 in) but less than 0.40 mm (0.016 in).
Spot – an area of contrasting colour.
Enamelled cast Iron — a product cast from molten iron and coated with enamel fused to the metal (see Porcelain enamel)
Note: The enamel coci’tirlg is hard, glossy, opaque, and acid resistant and, in combination with the solid cast won base, pioduces a rig4 durable product.
Finish — the texture and condition of a surface (excluding colour).
Fitting — a device that controls and guides the flow of water.
Note: See ASME Al 12.18. 1/CAN/CSA-B 125.1 and C4.N/CSA-B 125.3 for definitions of specIfic t)pes of fittings.
Fixture — a device that receives water, waste matter, or both and directs these substances into a drainage system.
Note: See ASME A 112.1 9.2/CSA 845.1 for definitions of specific types of fixturei
Flood level — the level at which water will overflow a fixture.
Inspection window — a circular opening 76 mm (3.0 in) in diameter cut into a sheet of flexible material and used to count the number of defects in the opening (see Table 1).
Lavatory — a washbowl or basin.
Slab type lavatory – a Lavatory that has the mounting surface for a faucet on top of a slab and does not have an elevated back.
Ledge back — a flat elevated surface at the back of a lavatory, sink, or laundry sink, not more than 51 mm (2.0 in) higher than the rim and extending the full length of the fixture, on which the supply fitting can be mounted and small articles can be placed, or a similar construction with a centre panel suitable for mounting a supply fitting.
Porcelain enamel —a vitreous or glossy inorganic coating that is bonded to the metal by fusion at high lemperature.
Rim — the unobstructed open edge of a fixture.
Satin finish — a very smooth surface with low or dull reflective properties.
Sheet steel — steel that can be satisfactorily porcelain enamelled, including the following:
(a) special-purpose enamelling iron or steel of lcw metalloid and copper conteni that is specially manufactured and processed for the production of porcelain-enamelled fixtures;
(b) special steels designed for porcelain-enamel application; and
(c) cold-rolled steel.
Shelf back — a fiat elevated surface at the back of a lavator) sink, or laundry sink more than 51 mm (2.0 in) higher than the rim and extending the full length of the fixture, on the top or front of which the supply fitting can be mounted and small articles can be placed, or a similar construction with a centre panel formed into the shelf suitable for mounting a supply fitting on either a horizontal or inclined surface.
Spill level — the level at which water will flow Out of one bowl into another bowl of the same fixture.
Visible surface – a surface of a fixture that is readily visible to an observer in a normal standing position after the fixture is installed.
Visible after Installation — a surface that remains visible (not necessarily from a normal standing position) after the fixture is installed.
4.1.4 Wall brackets
Wall brackets shall be used when slab-type lavatories are supported by cast iron legs.
42 (act iron thickness
Cast iron shall be at least 3 mm (0.1 3 In) thick when measured at least 25 mm (1.0 in) from the edge of the fixture.
Unless otherwise specified in this Standard, the tolerance on dimensions of 200 mm (8 in) and greater shall be ± 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 specified 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.
