This is the third edition of CSA 8.3, Thermoplastic hose and hose couplings for conducting propane and natural gas. It supersedes the previous editions published in 1975 and 1977.
This Standard applies to newly produced thermoplastic hose, hose couplings, and complete assemblies of hose and couplings used to conduct natural gas in a gaseous state and propane in either a liquid or gaseous state to be used at temperatures between -40°F (-40 °C) and 140° F (60 °C).
Hose assemblies covered in this Standard are installed in accordance with the appliance and/or the equipment manufacturers instructions. If installation instructions are not present, installation of this product shall be completed in accordance with the Natural Gas and Propane Installation Code, CSA B149.1.

Clause 4, Hose, covers hose having a rated working pressure of at least 350 psig (2.4 MPa) and a minimum burst pressure of five times the rated working pressure.
Clause 5, Couplings, covers hose couplings of a type to be used with the hose complying with Clause 4 of this Standard.
Clause 6, Hose assemblies, covers hose assemblies or types using hose and couplings complying with Clauses 4 and 5 of this Standard.
This Standard contains SI (Metric) units corresponding to the yard/pound quantities, the purpose being to allow the standard to be used in SI (Metric) units. (IEEE/ASTM SI 10, American National Standard for Metric Practice, or ISO 80000-1:2009, Quantities and units - Part 1: General, is used as a guide in making metric conversion from yard/pound quantities.) If a value for a measurement and a corresponding value in other units are stated, the first stated value is to be regarded as the requirement. The given corresponding value may be approximate. If a value for a measurement and a corresponding value in other units are both specified as a quoted marking requirement, the first stated unit, or both, are to be provided.
In this Standard, shall is used to express a requirement, i.e., a provision that the user shall 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.
