(d) Connections shall conform to sites and dimensions listed in Table I or 2. Joint connections are designed for use with hubless soil pipe couplings conforming tO the requirements of the Cast Iron Soil Pipe Institute Specification 310-85.
3 SIZES
(a) Sizes and dimensions of fittings shall conform to dimensions in Table I or 2.
(b) Opening size sequence is illustrated in Figs. 3 and 4.
4 MARKING
(a) Each titLing shall be marked with the inanufacturers name or trademark, and with “Sovcnt.”
(b) Fittings of gray cast iron do not require material marking. If the manufacturer elects to use malleable iron or ductile iron, the fitting shall he marked with “MI’ or “DI.”
5 MATERIAL
(a) The material used to manufacture the fittings shall be in accordance with ASTM A 126. Grade A.
(b) At the option of the manufacturer, fittings may be furnished of malleable iron complying with the requirements of ASTM A 197 or A 47, Grade 32510, or of ductile iron complying with ASTM A 395 or A 536, Grade 65-45-12
6 PITCH
All nominal 90 deg drain openings shall he pitched down toward the fitting in a slope of 1/4 mill (2.1%) of horiiontal pipe with reference to a horizontal plane.
8.3 Outside and Inside Diameter of Fitting
The diameters shall be within the tolerances shown in Table 3.
8.4 Center-to-End Dimensions
The center-to-end dimensions shall be within the tolerances shown in Table 4.
9 ALIGNMENT
The maximum allowable variation in the alignment of all openings shall be 0.06 in./ft (0.5%), except for openings that arc pitched.
10 TESTS
(a) Each fitting shall be subjected to a minimum hydrostatic pressure of 25 psi. The fitting shall not leak water or sweat at any part of the surface. Alternate tests that demonstrate ihe same degree of soundness and strength are acceptable.
(b) Manufacturers shall inspect fittings prior to shipment for the presence of cracks, holes, or other defects.
(c) Manufacturers shall be prepared to certify that their products meet the requirements of this Standard.
