Scope
1.1

This Standard covers mechanical couplings that are used to axially join pipes and fittings 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).

1.3

This Standard does not cover the joining of pipes and fittings with bell and spigot ends that use an elastomeric gasket seal.

1.4

Users should note the existence of other standards developed for different types of couplings or coupling materials, e.g., ASTM C1173, ASTM C1277, ASTM C1440, ASTM C1460, ASTM C1461, ASTM C1540, and ASTM D5926.

1.5

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the Standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.6

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.

Scope

1.1  

This Standard covers personal hygiene devices for water closets and specifies requirements for materials, construction, performance, testing, and markings.

1.2  

Products covered by this Standard include bidet sprayers and other retrofit personal hygiene devices intended

(a)    for water closets and water closet seats; and

(b)   to be used with hot and cold water or cold water only.

1.3  

The provisions of this Standard are not intended to prevent the use of alternative materials or methods of construction, provided such alternatives meet the intent and requirements of this Standard.

1.4  

In this Standard, "shall" is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; "should" is used to express a recommendation or that which is advised but not required; and "may" is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or alternative requirements; the purpose of a note accompanying a clause is to separate from the text explanatory or informative material.

Notes to tables and figures are considered part of the table or figure and may be written as requirements.

Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application.

1.5  

SI units are the units of record in Canada. In this Standard, the inch/pound units are shown in parentheses.

The values stated in each measurement system are equivalent in application; however, each system is to be used independently. Combining values from the two measurement systems may result in non-conformance with this Standard.

All references to gallons are to U.S. gallons.
