Scope

This Standard covers black crosslinked polyethylene (PEX) pipe and fittings for use in gas gathering, gas transmission, and gas distribution applications containing not more than 1% aromatic hydrocarbons. PEX pipes are pressure rated using either the ASTM HDB (hydrostatic design basis) method based on ASTM D2837, or the ISO MRS (minimum required strength) method based on ISO 9080 and ISO 12162.  This Standard describes PEX pipes that are used in a wide range of operating temperatures from -50ºC to 110ºC, in a variety of pipe sizes ranging from NPS 3 to NPS 54 for Nominal Pipe Sizes (NPS) sizes or DN 16 to DN 1000 for metric diameter nominal (DN) sizes, and pipes that are joined by the electrofusion process or mechanical fittings, but not by butt fusion.

  Scope

1.1  

This Standard covers thermoplastic nonpressure piping, including

(a)    drain, waste, and vent pipe and pipe fittings;

(b)   sewer and storm pipe and pipe fittings; and

(c)    accessories such as factory-assembled expansion joints, closet flanges, backwater valves, and cleanouts.

1.2  

This Standard specifies general requirements for compounds and for manufactured pipe and pipe fittings, the relevant test methods, and marking requirements.

1.3  

This Standard is intended to be used in conjunction with one of the other Standards in the CSA B181 or CSA B182 series to form a complete Standard for a particular product.

1.4  

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; 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 (nonmandatory) to define their application.

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.
