This is the second edition of CSA 2.29, Hand-held torches for fuel gas. It supersedes the previous edition published in 1997.

The major changes to this edition include the following:

a) removal of the mercurous nitrate immersion test;

b) addition of the salt spray and ammonia vapour test; and

c) updated formatting throughout the Standard.

This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group.

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

This Standard applies 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

a) for direct connection to

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

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

b) for direct connection to refillable containers meeting the requirements of CSA B339 and the Transportation of Dangerous Goods Regulations;

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

d) 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 Clause 4.7.1, there is no capacity limitation on the fuel container.

1.4

Torches covered by this Standard are intended to be used in accordance with the

a) applicable provisions of CSA B149.1;

b) requirements of the authority having jurisdiction; or

c) applicable provisions of CSA B149.1 and 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

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.

Larticle de la première partie est applicable avec les exceptions suivantes:

1.1 Remplacement:
La présente norme sapplique aux appareils de nettoyage à usage général pour utilisation domestique dont une partie est tenue à la main pendant le fonctionnement. Ces appareils sont destinés à nettoyer des surfaces telles que des fenêtres, des murs, des plafonds et des parois de piscines vides.

Le nettoyage peut être obtenu par lutilisation de brosses ou éléments analogues et de liquides de nettoyage avec ou sans additifs chimiques.

Des moyens peuvent être prévus pour chauffer et mettre le liquide de nettoyage sous pression.

La présente norme ne tient pas compte des dangers spéciaux existant dans les garderies denfants et autres locaux où de jeunes enfants ou des personnes âgées ou infirmes sont laissés sans surveillance; dans de tels cas des prescriptions supplémentaires peuvent être nécessaires.

La présente norme ne sapplique pas:

– aux appareils de nettoyage qui sont fixés en permanence à un bâtiment;
– aux appareils de nettoyage fonctionnant sous une pression dépassant 2,5 MPa (25 bar) ou sous une température de liquide dépassant 80°C;
– aux appareils de nettoyage pour usage commercial ou industriel.

Pour les appareils destinés à être utilisés dans les véhicules ou à bord des navires ou des avions, des règles supplémentaires peuvent être nécessaires.

Pour les appareils destinés à être utilisés dans les pays tropicaux, des règles spéciales peuvent être nécessaires.

Lattention est attirée sur le fait que dans de nombreux pays des prescriptions supplémentaires sont imposées par les organismes nationaux de la santé publique et les organismes nationaux responsables de la protection des travailleurs.

This clause of Part 1 is applicable except as follows:

1.1 Replacement:

This standard applies to portable electric heating tools and s imilar appliances, with or without motors.

Portable electric heating tools and similar appliances, hereinafter referred to as tools, which can be mounted on a support for use as fixed tools without any alteration of the tool itself, are within the scope of this standard.

Tools not intended for normal household use, but which nevertheless may be a source of danger to the public, such as tools intended to be used by laymen in shops, in light industry and on farms, are also within the scope of this standard.

Examples of tools that are within the scope of this standard are:
 

• soldering irons;
• desoldering irons;
• soldering guns;
• conduit-soldering tools;
• thermoplastic conduit-welding tools;
• plastic-welding tools;
• film-welding tools;
• household film-welding appliances;
• plastic-cutting tools;
• branding tools;
• burning-in pens;
• stripping pliers;
• glue guns;
• dehorning tools.

This standard does not take into account the special hazards which exist in nurseries and other places where there are young children or aged or infirm persons without supervision; in such c ases, additional requirements may be necessary.

This standard does not apply to:
 

• tools for high-frequency heating;
• arc welding and carbon-arc brazing equipment;
• tools intended to be used in explosive atmospheres.

For tools intended to be used in vehicles or on board ships or aircraft, additional requirements may be necessary.

For tools intended to be used in tropical countries, special requirements may be necessary.

Attention is drawn to the fact that in many countries additional requirements are specified by the national health authorities and the national authorities responsible for the protection of labour. /

This clause of part 1 is applicable, except as follows:

Replace the text by the following:

This International Standard applies to hand-held and hand- manipulated CURRENT CLAMPS. These CURRENT CLAMPS are for use in the measurement of current without interruption of the current path of the circuit in which it is measured. They may be stand- alone CURRENT CLAMPS which are themselves within the scope of part 1, or accessories to other equipment within the scope of part 1.

This standard does not apply to current transformers or current transducers intended for fixed installations.

1.4  
Environmental conditions

Replace the seventh dash by the following:

– primary input circuits with transient overvoltages according to INSTALLATION CATEGORIES (OVERVOLTAGE CATEGORIES) I, II, III and IV (see annex J). /

Scope

This Standard sets out requirements for fasteners for use with powder-actuated hand-held fastening tools complying with AS/NZS 1873.2.

Scope
