SCOPE

1.1

This Standard applies to newly-produced torches for use with propane, butane, natural gas, and MPS (methyl acetylene-propadiene stabilized). This standard applies to torches that aspirate atmospheric air for combustion.

1.2

These requirements apply to hand-held torches intended for industrial applications such as brazing, soldering, pre-heating for welding, heat treatment, and general applications such as grass burning, paint removal, and the eradication of weeds and insects.

1.3

Torches covered by these requirements are intended

for direct connection to

specification TC-2P and TC-2Q non-refillable containers, meeting the requirements of  CAN/CGSB-43.123 , and the Transportation of Dangerous Goods Regulations of Transport Canada; or

specification TC-39 non-refillable containers, meeting the requirements of CSA B339, and the Transportation of Dangerous Goods Regulations of Transport Canada;

for direct connection to refillable containers meeting the requirements of CSA B339   and the Transportation of Dangerous Good Regulations of Transport Canada;

to incorporate an integral, refillable or non-refillable cylinder that meets the requirements of Items a) or b) above; or

for hose connection to the fuel gas supply, with or without a regulator.

NOTE: Provided that a torch meets the requirements of this Standard, there is no maximum or minimum rate of firing and except as noted in 4.4.13.1, there is no capacity limitation on the fuel container.

1.4

Torches covered by these requirements are intended to be used in accordance with the

applicable provisions of CSA B149.1; and/or

requirements of the authority having jurisdiction.

1.5

This Standard applies to torches constructed entirely of new, unused parts and materials.

1.6

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.

1.7

If a value for measurement is followed by a value in other units in parentheses, the second value may be approximate. The first-stated value is the requirement.
