CSA A283:24

Preface This is the sixth edition of CSA A283, Certification of laboratories for concrete. It supersedes the previous editions published in 2019, 2006, 2000, 1980, and 1974. This edition includes the following changes: a) Clause 3 reverting from supervising professional to supervising engineer to clarify that most authorities having jurisdiction require a person licensed to practice engineering or limited license holder where applicable; b) Clause 5.1.1.2 recommendation for implementation of quality management systems; c) Clause 5.2.2.2 removal of responsibilities elsewhere in this Standard and the monthly sign-off; d) Clause 5.4.3 clarification of requirements for reporting non-compliant test specimens and deviations from test methods and standard practices in accordance with CSA A23.2; e) Clause 6 categories of certification and listing of additional tests for which laboratories may be certified have been revised to reflect changes in, and to be consistent with, CSA A23.1/A23.2, and to take into account developments in the concrete industry; and f) Table 1, addition of equipment verification/calibration requirements, for CSA A23.2-14A and CSA A23.2-27C. This Standard has been referenced by CSA A23.1, Concrete materials and methods of concrete construction, since its sixth edition (1977). This Standard is considered suitable for use for conformity assessment within the stated scope of the Standard. CSA Group acknowledges that the development of this Standard was made possible, in part, by the financial support of the Canadian Council of Independent Laboratories. This Standard was prepared by the Technical Committee on Qualification Code for Concrete Testing Laboratories, under the jurisdiction of the Strategic Steering Committee on Construction and Civil Infrastructure, and has been formally approved by the Technical Committee. Scope 1.1 General This Standard provides a means of determining a concrete laboratory’s capability to test concrete and related materials. It provides for three levels of certification: basic concrete, concrete aggregate, and advanced concrete certification. Its purpose is to ensure the services obtained from a concrete testing laboratory are of acceptable quality and performance. It also provides minimum requirements for the test equipment, qualifications of personnel who test concrete, and their performance in testing; however, this Standard should not be construed as a standard detailing the technical ability and expertise necessary to provide a comprehensive consulting service in concrete technology. 1.2 Laboratory certification This Standard addresses a) the requirements for laboratory certification; and b) the administration of these requirements. 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.
