Construction and Engineering

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 that 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.

1.1

This Standard provides minimum requirements for the manufacture of glulam of those species specified in CSA O86. The Standard also provides minimum requirements for the block-gluing and re-gluing of glulam components into larger finished glulam. Storage, handling, and installation of products subsequent to manufacture are not covered by this Standard.

1.2

The design criteria for glulam manufactured in accordance with this Standard are covered in CSA O86. Requirements for the development of specified strengths and modulus of elasticity for glulam are provided in Annex B.

1.3

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

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
