Scope

1.1
The CSA O80 Series of Standards specifies requirements related to the preservation and fire retardance of wood through chemical treatment (pressure and thermal impregnation). The subjects covered include materials and their analysis, pressure and thermal impregnation procedures, and fabrication and installation to put treated wood into service.

1.2
This Standard lists reference publications and provides definitions applicable to the entire CSA O80 Series of Standards. This Standard also describes how the CSA O80 Series of Standards differs from related AWPA Standards and addresses the need for preservative registration. Recommendations on the use of the CSA O80 Series of Standards and related AWPA Standards can be found in Annex A.

Note: In Canada, preservative registration is carried out through Health Canada’s Pest Management Regulatory Agency.

1.3
The requirements and recommendations of the CSA O80 Series of Standards are based solely on the treatment efficacy of the chemicals in question. The CSA O80 Series of Standards does not necessarily take all laws and regulations into account.

Note: It is the responsibility of the users of the CSA O80 Series of Standards to ensure that their use of preservatives does not conflict with applicable laws and regulations.

1.4
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.

Scope

1.1

This standard covers asphalt core boards intended for use as a substrate to receive an asphalt-based, low-slope roof membrane system (built-up or modified-bitumen).  In such systems, the roofing membrane may be adhered with hot asphalt or cold-applied adhesive or heat welded to asphalt core board or mechanically attached through asphalt core board to the structural deck. This standard applies to asphalt core boards installed horizontally and vertically (on flashings and parapets). 

1.2

This standard does not specify requirements for the use of asphalt core board in protecting a substrate.

This standard does not address asphalt based protection boards used in waterproofing; for information on these products, refer to ASTM Standard Specification D6506.

Asphalt core boards addressed in this standard are not intended as substrates for vertical flashings unless fully supported, in a low-slope roofing system.

1.3

The values given in SI (metric) units are the standard.  The values given in parentheses are for information only.
