CSA B140.2.2-1971 (R2020)

Preface:

This is the first CSX Standard covering minimum requirements for safe operation, acceptable performance, construction, marking and testing of pressure atomizing oil burner nozzles.

Since it is the intent to determine consistency of similarly identified nozzles from one production lot to the next rather than compliance with absolute values, such compliance is determined by comparison of results of the tests to an originally established datum. For example, it is significant that the spray angle, as determined by these tests, be within acceptable limits of the angle of an original nozzle rather than that a nozzle marked ?60 degrees spray? actually spray at 60 degrees.

This Standard was prepared by the Committee on Oil Burning Appliance Standards, under the jurisdiction of the Sectional Committee on Oil Burning Equipment, and was formally approved by these Committees.

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.
