31、8-14Compressed natural gas fuelling stations installation code1 Scope1.1 This Code applies to compressed natural gas fuelling stations that may be employed for fleet and public dispensing operations. 1.2 The scope of this Code does not include fuelling vehicles with liquefied natural gas (LNG). At a

32、n LNG facility with CNG vehicle fuelling, this Code applies only to facilities downstream of the isolation valve at the outlet of the natural gas vaporizer. 1.3 In this Code, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the c

33、ode; “should” is used to express a recommendation or that which is advised but not required; “may” is used to express an option or that which is permissible within the limits of the code; and “can” is used to express possibility or capability.Notes accompanying clauses do not include requirements or

34、 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 informativ

35、e (non-mandatory) to define their application.1.4 All references to “kPa (psi)” throughout this Code are to be considered gauge pressures, unless otherwise specified. 1.5 The values given in SI units are the units of record for the purposes of this Code. The values given in parentheses are for infor

36、mation and comparison only. This Code contains SI (metric) units corresponding to the yard/pound quantities, the purpose of which is to allow the Code to be used in SI (metric) units. If a value for a measurement and a corresponding value in other units are stated, the first stated value is to be re

37、garded 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 shall be provided.B108-14Compressed natural gas fuelling stations ins

38、tallation codeMarch 2015 2015 CSA Group 8In this Code, the word “gallon” indicates a U.S. Gallon equivalent to 3.785 liters water capacity.Notes: 1) IEEE/ASTM SI 10 or ISO 80000-1 are used as a guide in making metric conversion from imperial (yard/pound) quantities.2) This code was developed origina

39、lly using the imperial system of measurement and subsequently converted to metric units having three (3) significant digits. Every attempt has been made to provide accurate conversion values; however, when designing systems using these values engineering judgment needs to be applied.2 Reference publ
