CSA Group Pressure Atomizing Oil Burner Nozzles B140.2.2-1971 (R2015)

Scope 1.1 This Standard states the minimum requirements for nozzles which are designed for installation in oil burners of the pressure atomizing type. 1.2 This Standard includes requirements for construction, marking, and performance to ensure consistent operation of nozzles. 1.3 The intent of these requirements is to determine the consistency of flow rate, nominal spray angle, and nominal spray pattern, of any subsequent production lot of similarly identified nozzles to an original lot, rather than to compare these characteristics to any absolute or specified value. 1.4 These requirements apply to nozzles which are: a) Of the capacity range up to and including 2.00 gallons (U.S.) per hour; and b) Primarily intended for use with oil not heavier than grade No. 2. 1.5 Nozzles designed for use in a specific burner may be evaluated to the intent of these requirements.
