1.1 General

This Standard provides a set of hydraulic testing specifications and performance metrics for temporary emergency flood protection barriers in Canadian environments by

defining standard terminology to use when describing floods and flood protection barriers;

detailing a set of hydraulic testing requirements for flood protection barriers (see exclusions in Clause 1.2);

outlining different environments for flood protection barrier use (i.e., environmental categories) and discussing the testing and performance requirements for these environments; and

providing technology developers and testing laboratories with a defined and consistent set of hydraulic testing conditions required for flood barrier deployment in Canadian environments.

Note: See also ANSI/FM 2510 and BSI Standards Publication Parts 1 and 2.

1.2 Exclusions

This Standard applies only to the hydraulic testing of temporarily deployed emergency flood protection barrier systems (i.e., those systems that are removed after flood events). Permanently affixed flood barriers fall outside of the scope of this Standard.

The Standard does not apply to initial planning, new development, new expansions and construction, or site closure/remediation.

This Standard does not apply to stormwater systems, which are covered in CSA W211.

Out-of-scope items are noted for awareness only, but organizations may choose to include those aspects to fit their scope needs. These out-of-scope items include but are not limited to

any types of testing of the flood protection barrier outside of hydraulic testing (e.g., strength of materials[KC1] [KC2] , UV exposure and degradation, foundation design);

any type of non-temporary or permanently affixed or installed flood protection barrier (e.g., walls, seawalls, dykes);

any testing of the barrier individual components (e.g., connection clamps, anchor bolts, materials testing);

any specifications around or testing of auxiliary equipment that supports flood protection barrier deployment (e.g., flood abatement pumps, backwater valves); and

any specifications around the manufacturing process of the flood protection barriers.

1.3 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.

1.4 Units of measurement

The values given in SI units are the units of record for the purposes of this Standard. Dimensional lumber references refer to U.S. customary units as these products are commonly referred to within Canada by their trade name in those units.

Note: See Annex A.
