34、140F (60 C).1.3Type I hose refers to hose with a maximum operating pressure of 350 psig (2.4 MPa) and a minimumburst pressure of 1750 psig (12.1 MPa).1.4Type II and Type III hose refers to stainless steel braid reinforced hose designed with a maximumoperating pressure of 350 psig (2.4 MPa) and a min
35、imum burst pressure as shown in Table 2,Type II andType III Hose.1.5Hose assemblies covered in this Standard are installed in accordance with the appliance and/or theequipment manufacturers instructions. If installation instructions are not present, installation of thisproduct shall be completed in
36、accordance with the Natural Gas and Propane Installation Code, CSAB149.1.Note: Per the Natural Gas and Propane Installation Code, CSA B149.1, this Standard does not apply to theappliance applications covered by the Standard for Connectors for Gas Appliances, ANSI Z21.24 CSA 6.10, theStandard for Gas

39、osite hose and hose couplings forconducting propane and natural gasAugust 2015 2015 CSA Group 111.8This Standard contains SI (Metric) units corresponding to the yard/pound quantities, the purpose beingto allow the standard to be used in SI (Metric) units. (IEEE/ASTM SI 10, American National Standard
40、 forMetric Practice, or ISO 80000-1:2009, Quantities and units Part 1: General, is used as a guide inmaking metric conversion from yard/pound quantities.) If a value for a measurement and acorresponding value in other units are stated, the first stated value is to be regarded as therequirement. The
41、given corresponding value may be approximate. If a value for a measurement and acorresponding value in other units are both specified as a quoted marking requirement, the first statedunit, or both, are to be provided.1.9In this Standard,“shall” is used to express a requirement, i.e., a provision tha
42、t the user shall satisfy inorder to comply with the standard; “should” is used to express a recommendation or that which isadvised but not required; and “may” is used to express an option or that which is permissible within thelimits of the standard.Notes accompanying clauses do not include requirem
