1.1 General

This Standard provides requirements for in‑service examinations of concrete containment structures which includes, but is not limited to the following structural and non-structural elements:

a) concrete;

b) reinforcement (pre-stressed and non-pre-stressed);

c) steel (e.g., liner, embedded parts, anchors);

d) non-metallic liners and coating systems;

e) joint sealants and water stops; and

f) elements necessary to support containment structure (e.g. foundations).

Note: In-service examination and testing in accordance with this standard form an integral part of the overall aging management of concrete containment structure. CSA N287.8 defines requirements for aging management of concrete containment structure.

1.2 Integrated leakage rate tests (ILRTs)

This Standard also provides requirements for integrated leakage rate testing (ILRT) of the containment boundary.

1.3 Interface with CSA N285.5

In-service examination of containment system components designed in accordance with the CSA N285 series of Standards are beyond the scope of this Standard.

Note: CSA N285.5 provides requirements for periodic inspection of CANDU nuclear power plant containment components that are made of metallic or plastic materials and that form the containment boundary or are part of fluid handling systems that penetrate the containment structure.

1.4 Interface with other CSA N287 standards

This Standard is used in concert with the other standards of CSA N287 series, as applicable.

1.5 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.

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

1.6 Use of shall consider and shall be considered

In this Standard, “shall be considered” or “shall consider” means that the user evaluates the impact and documents any decisions.

Note: Examples of decision outcomes can include no action, revised operating procedures, design features.

1.1 General 
This Standard contains requirements for the material, design, manufacture, marking and testing of serially produced, refillable Type NGV 2 containers intended for the storage of compressed natural gas (CNG) for vehicle operation. These containers
a) are to be permanently attached to the vehicle;
b) have a capacity of up to and including 1000 L (35.4 ft3) water capacity. 
Note: In Canada, the use of gas containers is governed by the Act. In the United States, the use of gas containers is governed by the U.S. Department of Transportation/National Highway Traffic Safety Administration.
 
1.2 Container types 
 
1.2.1 Cylindrical containers 
 
Type NGV 2 containers are designated as follows: 
a) Type 1: seamless metal container;
b) Type 2: hoop-wrapped container with continuous filaments and a metal liner;
c) Type 3: fully wrapped container with continuous filaments and with a metal liner; and
d) Type 4: fully wrapped container with continuous filaments and with a nonmetallic liner.
 
1.2.2 Conformable containers 
 
Conformable container types are designated as follows: 
a) CT1: container of a non-cylindrical or non-spherical (i.e., irregular) shape without a protective shell;
b) CT2: container of a non-cylindrical or non-spherical (i.e., irregular) shape within a full or partial protective shell, where the shell  acts as a shield but does not directly assist the pressure-containing elements with containing gas pressure; and
c) CT3: container of a non-cylindrical or non-spherical (i.e., irregular) shape within a protective shell, where the shell  acts  as a shield and directly assists the pressure-containing elements with containing gas pressure.
 
1.2.3 Conformable container types
 
The conformable container types are an additional identifier that is used in combination with the container type. A conformable container is designated based on the design as a Type 1 (metal) to Type 4 (continuous filament with a nonmetallic liner) with the additional conformable type identifier. For example, a Type 4 CT2 container would be required to meet the criteria for a Type 4 container as well as the criteria specified for a CT2 container. 
 
1.3 Exclusions 
This Standard does not cover welded metal containers or welded metal  liners. 
 
1.4 Precedence of requirements 
Where a clause in this Standard conflicts with codes or standards referenced in this Standard, the requirements of this Standard take precedence. 
 
1.5 Requalification of containers 
Type 1 steel containers may be requalified for further service in accordance with the procedure described in Annex D. 
 
1.6 Canadian specific requirements 
Annex A contains requirements that are applicable only to Canada.
 
1.7 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. 
Annexes are designated normative (mandatory) or informative (non-mandatory) to define their application. 
 
1.8 Units of measure 
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.
