Draft Scope/Description:

1.1

This Standard applies to oil burners of the atomizing type, irrespective of size, firing rate, or grade* of fuel oil, that are designed primarily for installation in warm-air, hot-water, and steam-heating equipment.

*As specified in CSA B140.0, except for grade B6-B20 which is specified in ASTM D396.

1.2

This Standard applies to atomizing-type oil burners that are a part of an assembly in appliances such as ovens, heaters, ranges, and special furnaces.

1.3

This Standard also applies to integral atomizing-type burners, where they are part of a complete appliance.

1.4

This Standard applies to certain components and accessories (e.g., fuel units and combustion safety controls) for atomizing-type oil burners.

1.5

This Standard states the minimum requirements for nozzles that are designed for installation in oil burners of the pressure atomizing type.

1.6

This Standard includes requirements for construction, marking, and performance to provide consistent operation of nozzles.

1.7

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.

1.8

These requirements apply to nozzles that are:

(a) Of the capacity range up to and including 7.6 L/h (2 US gph); and

(b) Primarily intended for use with fuel oil not heavier than grade No. 2, and for fuel oils B6-B20.

1.9

Nozzles designed for use in a specific burner may be evaluated to the intent of these requirements.

1.10

In this Standard, “shall” is used to express a requirement, i.e., a provision that the user is obliged to satisfy in order to comply with the standard; “should” is used to express a recommendation or that which is advised but not required; and “may” is used to express an option or that which is permissible within the limits of the Standard.

Notes accompanying clauses do not include requirements or 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 informative (non-mandatory) to define their application.

1.11

The values given in SI units are the units of record for the purposes of this Standard. The values given in parentheses are for information and comparison only.
