CSA W212:25

Description

Preface This is the first edition of CSA W212, Temporary flood protection barrier performance testing for Canadian climates . CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of the National Research Council of Canada. This Standard was prepared by the Subcommittee on Flood Protection Barriers — Municipal Selection and Deployment Guide, under the jurisdiction of the Technical Committee on Flood Resiliency and the Strategic Steering Committee on Natural Resources, and has been formally approved by the Technical Committee. This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope 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 a) defining standard terminology to use when describing floods and flood protection barriers; b) detailing a set of hydraulic testing requirements for flood protection barriers (see exclusions in Clause 1.2) . c) outlining different environments for flood protection barrier use (i.e., environmental categories) and discussing the testing and performance requirements for these environments; and d) providing technology developers and testing laboratories with a defined 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 a) any types of testing of the flood protection barrier outside of hydraulic testing (e.g., strength of materials, UV, foundation design); b) any type of non-temporary or permanently affixed or installed flood protection barrier (e.g., walls, seawalls, dykes); c) any type of flood protection barriers for structural openings (e.g., doors, windows); d) any testing of the barrier individual components (e.g., connection clamps, anchor bolts, materials testing); e) any specifications around or testing of auxiliary equipment that supports flood protection barrier deployment (e.g., flood abatement pumps, backwater valves); and f) 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.
