1.2 Terminology

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.

Draft Amendment to C22.1

1.1 Application
This Standard applies to the safe storage, handling, and use of portable oxygen systems for medical or therapeutic use at the patient bedside. It includes portable oxygen systems which provide medical oxygen in high-pressure oxygen cylinders, liquid oxygen systems, and oxygen concentrators. in residential buildings and health care facilities.

1.2 Inclusions
This Standard includes requirements for maximum aggregate storage quantities of gaseous and liquid oxygen.

1.3 Exclusions
This Standard shall not apply to veterinary hospitals, gas mixes containing oxygen (e.g., 50/50 mix of nitrous oxide and oxygen, M size (22L H2O) or larger high pressure cylinders, and liquid oxygen 65L reservoirs or greater) and the safe storage, use, and handling of portable Oxygen systems which are intended for use on a Medical Gas Pipeline System. See CSA Z7396.1 - Medical gas pipeline systems - Part 1: Pipelines for medical gases, medical vacuum, medical support gases, and anaesthetic gas scavenging systems for further information.

1.3 Terminology
In CSA Standards, “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; “may” is used to express an option or that which is permissible within the limits of the standard; and “can” is used to express possibility or capability. 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.

1.4 Values
The values given in SI (metric) units are the standard. The values given in parentheses are for information only.

1.1
These requirements cover EV plugs, EV receptacles, vehicle inlets, vehicle connectors, and EV breakaway couplings, rated up to 800 amperes and up to 600 volts ac or dc. These devices are intended for use with conductive electric vehicle supply equipment (EVSE), and are intended to facilitate the conductive connection from the EVSE to the vehicle. These devices are
for use in either indoor or outdoor nonhazardous locations in accordance with Annex A, Ref. No. 1.

1.2
This Standard does not directly apply to any device that is not intended for use as described in 1.1.

1.3
In the text of this Standard, the term ″device″ refers to any product covered by this Standard. The letters ″EV″ refer to an electric vehicle, including plug-in hybrid vehicles, hybrid vehicles, electric vehicles, battery electric vehicles, and similar vehicles.

1.4

This standard does not apply to other connection systems that do not incorporate equipment of the pin and sleeve type, such as pantographs. 

1 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 the following types of mechanical couplings:

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.

       e) Type 5: couplings that have an integral restraint feature which enables the couplings to be used as an alternative to external joint restraint at changes of direction and locations subject to extended periods of maximum flow.

Notes:

1) 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).

2) Type 5 couplings are an alternative to bracing as indicated in Annex A.

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, ASTM D5926, and ASTM A1128.

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.
