CSA S808:14 (R2019)

Preface This is the first edition of CSA S808, Specification for fibre-reinforced polymer (FRP) materials for externally reinforcing structures. CSA acknowledges that the development of this Standard was made possible, in part, by the financial support of the following: ISIS Canada Network Association, Public Works and Government Services Canada, Pultrall Inc., Freyssinet Canada Ltd., BASF Canada Inc., and Sika Canada Inc. Scope 1.1 This Standard covers the manufacturing process and testing requirements of fibre-reinforced polymer (FRP) wet layup composite systems, pre-cured FRP plates, and FRP bars externally bonded as structural strengthening materials for structures (concrete, steel, wood, and masonry). 1.2 This Standard covers FRPs comprised of a) glass, carbon, or aramid fibres; and b) isophthalic polyester, vinylester, or epoxy resins. This Standard only covers the fabric and saturating resin that comprise the FRP system. Primers, adhesives, and putty fillers are outside the scope of this document. 1.3 This Standard covers FRP systems with continuous, unidirectional or bi-directional fibres, fabricated using wet layup. This Standard only covers FRP systems with bi-directional fibres made up with only one type of fibre and with fibers oriented 0° and 90°. Bi-directional laminates that intend to provide strength in more than one direction are not covered by this specification: it means that for bi-directional FRP systems oriented 0° and 90°, only the warp direction (fibres oriented 0°) of the laminate is providing strength. 1.4 This Standard covers FRP bars or bars that are part of a grid having solid prismatic cross sections with continuous fibres in the longitudinal direction. 1.5 This Standard covers FRP plates having nominally rectangular cross-section. 1.6 In this Standard, FRPs are classified on the basis of their fibres. 1.7 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 normative clauses from 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.
