CSA B602:2020 pdf download.Mechanical couplings for drain, waste,and vent pipe and sewer pipe
1,1 CSA B602 covers mechanical couplings that are used to axially join pipes and fttings in non-pressure drain, waste, and vent (DWV) piping systems and sewer piping systems located inside or outside buildings and above ground or underground.
Notes:
1) Caution should be exercised when installing mechanical couplings at low temperatures. The coupling manufacturer should be consulted.
2) Caution should also be exercised when installing mechanical couplings at the base of stacks, at cleanouts, or at offsets in a piping system (see Annex A).
1.2 This Standard specifies requirements for mechanical couplings of the following types:
a) Type 1: couplings that are used to join pipes of the same or different materials or sizes and that incorporate a centre stop and an external shield.
b) Type 2: couplings that are used to join pipes of the same or different materials or sizes, but for which a centre stop and/or shear ring are allowed but not required.
c) Type 3: couplings used to join hubless cast iron pipe and fittings. Such couplings are composed of a stainless steel shield, a clamp assembly, and an elastomeric sealing component that complies with ASTM C564.
d) Type 4: elastomeric bellows expansion joint couplings used to join pipe of the same or different materials or sizes incorporating pipe stops.
Note: Pipe and pipe-fitting materials that may be joined include
a) fibrocement (CSA B127.3);
b) cast iron (CSA B70);
c) concrete (CSA A257 Series and ASTM C14);
d) copper (ASTM B306);
e) acrylonitrile-butadiene-styrene (ABS) (CSA B181.1, CSA B182.1, ASTM D2661, and ASTM F628);
f) polyvinylchloride (PVC) (CSA B181.2, CSA B182.1, CSA B182.2, ASTM D2665, and ASTM F891);
g) galvanized steel (ASTM A53/A53M); and
h) vitrified clay (ASTM C700).
5.1.1.1 Components
If a component meets the requirements of this Standard, the manufacturer's production of the compound of which the component is made may generate reprocessed scrap material and clean rework material.
Type 3 couplings shall be made of elastomeric components made from a properly vulcanized virgin elastomeric compound where the primary elastomer is polychloroprene or neoprene. The gaskets shall be tested in accordance with ASTM C564 and ASTM D3677. Scrap material and rework material shall not be used.
5.1.1.3.1 Type 3 coupling tests performed in accordance with Clauses 5.1.2, 5.1.3, 5.1.4.2.3, and 5.1.11 shall
a) begin on the day of production; and
b) be performed on each size and type of gasket produced on the day of production.CSA B602 pdf download.
