Preface This is the second edition of CSA S807, Specification for fibre-reinforced polymers. It supersedes the first edition published in 2010. Changes to this edition of S807 include the following: - change to the scope of the Standard to include material properties of FRPs and the introduction of basalt fibers and specification of E-CR glass; - addition of fine aggregate for sand coating; and - addition of production lot size for straight, bent, and anchor-headed bars. CSA acknowledges that the development of this Standard was made possible, in part, by the financial support of the following: Ontario Ministry of Transportation, le ministère des Transports du Québec, la Mobilité durable et de l\'Électrification des transports, Fiberline Composites Canada, Tuf-Bar Inc., Pultrall Inc., Owens Corning Infrastructure Solutions, Shandong Safety Industries Co., Ltd, and B&B FRP Manufacturing Inc. 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 This Standard covers the material properties and the manufacturing requirements of fibre-reinforced polymer (FRP) bars or bars that are part of a grid for use in non-prestressed internal reinforcement of concrete components of structures (e.g., bridges, buildings, and marine structures). 1.2 This Standard covers FRPs that comprise a) E-CR glass, carbon, aramid, or basalt fibres; and b) isophthalic polyester, vinylester, or epoxy resins. 1.3 This Standard covers FRP bars having nominally solid circular or rectangular cross-section. 1.4 This Standard does not include FRP bars made of more than one type of fibre. 1.5 In this Standard, FRPs are classified on the basis of their fibres, strength, modulus, and durability. 1.6 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.
