scope:

This Standard specifies requirements for pre-operational proof testing (PPT) of concrete containment structures and integrated leakage rate testing (ILRT) of the containment boundary. Concrete containment structures includes 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 the containment structure (e.g., foundations).

The requirements for containment components are addressed in CSA N285.0. Containment components may be tested coincident with the containment structures as specified in this Standard.

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

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.
