This is the fourth edition of CSA A283, Qualification code for concrete testing laboratories. It supersedes the previous editions published in 2000, 1980, and 1974.
This Standard specifies requirements and procedures for certifying laboratories engaged in the testing of concrete. It provides for three levels of certification: basic, intermediate, and advanced. Its purpose is to ensure that the services obtained from a concrete testing laboratory are of acceptable quality and performance. It sets the minimum requirements for the performance of personnel and equipment only; it should not be construed as a Standard detailing the technical ability and expertise necessary to provide a comprehensive consulting service in concrete technology.
This Standard provides a means of determining a concrete laboratory's capability to test concrete and related materials. It also provides minimum qualification requirements for personnel who test concrete.
This Standard addresses (a) the requirements for laboratory certification; and (b) the administration of these requirements.
In CSA Standards, 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; may is used to express an option or that which is permissible within the limits of the standard; and can is used to express possibility or capability.
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.
