CSA 8.3-15:2020 pdf download.Thermoplastic hose and hose couplings for conducting propane and natural gas
1 Scope
1.1 CSA 8.3-2015 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).
1.2 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.
Note: Per the Natural Gas and Propane Installation Code, CSA B149.1 this Standard does not apply to appliance applications covered by the Standard for Connectors for Gas Appliances, ANSI Z21.24●CSA 6.10, the Standard for Gas Hose Connectors for Portable Outdoor Gas-Fired Appliances, ANSI 221.54●CSA 8.4, the Standard for Connectors for Movable Gas Appliances, ANSI Z21.69●CSA 6.16, the Standard for Connectors of Outdoor Gas Appliances and Manufactured Homes, ANSI Z21.75●CSA 6.27, and the Standard for Gas Hose Connectors for Portable and Movable Gas Appliances, ANSI Z21.101●CSA 8.5.
1.6
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.
4.1.2 Design tolerances
The internal diameter of the hose shall be equal to the nominal diameter, plus 0.015 in (0.381 mm) or minus 0.008 in (0.203 mm) for sizes up to and including 1/2 in (12.7 mm) and plus 0.030 in (0.762 mm) or minus 0.015 (0.381 mm) for sizes up to and including 1 in (2.54 cm). The tolerances of the outside diameter of the hose shall be the same as those specified for the internal diameter.
4.1.3 Inner tube construction
The inner tube shall be made of seamless thermoplastic. The tube shall have a smooth bore free from defects in workmanship, from fisheyes, die lines, or other imperfections and be free of all foreign matter. The thickness of the tube shall not be less than 0.025 in (0.635 mm).CSA 8.3-2015 pdf download.
