2.15 Applicability
Components made of other materials shall be in accordance with their applicable product standards, codes, or listing (where available), and the joint shall be in accordance with the requirements of this Standard.
2.16 Joints
The joints shall be of a smooth and clean surface. Surfaces shall not have any defects or irregularities, which could affect the functioning or which would interfere with normal joining of the product.

Different sealing ring materials shall be permitted to accommodate various applications in accordance with the manufacturer’s instructions. Material shall be marked or color-coded by the manufacturer as acceptable to identify.
2.18 Other Gravity and Vacuum Fittings
Custom-fabricated fittings, to transport sanitary waste and various other fluids and effluents, shall meet the dimensional requirements of this Standard when required.
2.19 Other Floor Drain Dimensions
Floor drain dimensions shall comply with Tables 39 through 44.
2.20 Cleanout Fitting
Stainless steel, gas-tight covers shall comply with Table 45.
2.21 StainLess Steel, FLoor Drain Water Trap
Stainless steel, floor drain water traps shall comply with Table 46.
2.22 Other Trench Drain Dimensions
Trench drain dimensions shall comply with Table 47.
3 TEST METHODS AND PERFORMANCE REQUIREMENTS
3.1 Tensile Strength
Mill certificates shall he furnished upon request to verify tensile strength in compliance with the minimum requirements. The pipe and fittings for Type 304 stainless steel shall have a minimum tensile strength of 500 MPa (73,000 psi). The pipe and fittings for Type 316L stainless
steel shall have a minimum tensile strength of 485 MPa (71,000 psi).
3.2 Hardness Pipe and Fittings
3.2.1 Type 304. The Brinell Hardness for Type 304 stainless steel shall be between 130 and 180.
3.2.2 Type 3161. The Brinell Hardness for Type 316L stainless steel shall be between 120 and 180.
3.3 Water Tightness of Welds and Pipe Joints
3.3.1 All pipe fittings and joints shall be watertight from 0 kPa to 50 kPa (0 psi to 7.25 psi). Testing shall be performed in accordance with para. 3.4.1.
3.3.2 For use in areas subject to elevated pressure (e.g., lift stations and rainwater leaders subject to backups) the manufacturer shall establish maximum pressure rating according to the test described in para. 3.4.2.
3.4 Weld and Joint Test
3.4.1 Test Method. A representative assembly of the fittings being listed that includes the pipe and joints shall be restrained per the manufacturer’s final installation guidelines at ambient temperature under hydrostatic pressure 50 kPa (7.25 psi) for 20 mm. There shall be no leaks.
3.4.2 lIthe manufacturer’s pressure rating is higher than 50 kPa (7.25 psi) and after a successful test per para. 3.4.1, the hydrostatic pressure shall be increased in increments of 50 kPa (7.25 psi) up to 300 kPa (43.51 psi) and observed for 5 mm at each increment. Any leaking shall be considered a failure. The last successful test increment shall be recorded as maximum pressure rating for intermittent, elevated pressures.
3.5 Internal Sealing Ring (0-Ring)
3.5.1 Test Methods and Performance Requirements. Elastomeric sealing rings shall comply with the following:
(a) Elongation shall be a minimum of 250% when tested in accordance with ASTM D 412.
(b) Tear resistance shall be a minimum of 150 lb/in. when tested in accordance with ASTM D 624 using Die c.
(c) Resistance to heat aging shall be determined as follows when conditoned in accordance with ASTM D 573 at 70°C ± 2°C for 96 H ± 0.5 H:
(1) maximum increase in hardness of 10 points when tested in accordance with ASTM D 2240 (Shore A durometer)
(2) maximum loss in tensile strength of 15% when tested in accordance with ASTM D 412.
3.6.1 Acceptance Criteria. The maximum allowable
drop in vacuum is 7 kPa (2 in. of mercury).
4 MARKINGS
Pipe, fttings, and drains shall be permanently marked
with the following:
(a) manufacturer’s name or registered trademark.
(b) SI or customary nominal size.
(c) date of manufacture (year, month, and day) on all pipe and fittings.
(d) Type of alloy pipe, Type 304 and Type 316L shall be marked along the continuous length of pipe. Type 304 shall be marked to read“above ground only.”
5 FLOOR DRAIN DIMENSIONS
Floor drain dimensions shall be as shown in Tables 39 through 44.
6 TRENCH DRAIN DIMENSIONS
Trench drain dimensions shall be as shown in Table 47.
