21、urces Canada Limited,Calgary, Alberta(Replaces p. vi, November 2001)vi Canadian Standards Association Battery ChargersDecember 20084.2.1.2 Enclosures for battery chargers shall be formed and assembled so that they will have the strength and rigidity necessary to resist the abuse to which they may be

22、 subjected, without increasing their fire and accident hazards due to partial collapse and without reduction of spacings, loosening or displacement of parts, or other serious defects.4.2.1.3 If an electrical instrument, such as a meter, forms part of the enclosure, the face or the back of the instru

23、ment housing, or both together, shall comply with the requirements for an enclosure.4.2.1.4 Clause 4.2.1.3 shall not apply to instruments connected in secondary circuits if damage to or deterioration of the materials of which the housing is made will not result in a risk of fire or electric shock.4.

24、2.1.5 The enclosure of a battery charger intended to be permanently mounted under the hood of an automobile shall comply with the water test specified in Clause 6.20.4.2.1.6 For applications where a battery charger may be subjected to the action of oil, acid fumes, moisture, dust, or other injurious

25、 materials in normal operation, the protection afforded the enclosed components shall be subject to investigation.4.2.1.7 Iron or steel parts shall be protected against rusting, as required by CSA Standard CAN/CSA-C22.2 No. 0.4.2.2 Thickness of Enclosures4.2.2.1 Except as specified in Clauses 4.2.2.

26、2 and 4.2.2.3, the thickness of sheet metal for enclosures shall be not less than that specified in Tables 1 and 2.4.2.2.2 At points to which a wiring system is to be connected, uncoated steel shall be at least 0.78 mm thick and zinc-coated steel at least 0.88 mm thick.4.2.2.3 The thickness of sheet

27、 metal for enclosures at points other than where a wiring system is to be connected may be less than that specified in Tables 1 and 2, provided that the enclosure complies with the compression test specified in Clause 6.14 and the deflection test specified in Clause 6.15.4.2.2.4 With reference to Ta

28、bles 1 and 2, a supporting frame shall consist of a structure of angles, channels, or folded rigid sections of sheet metal that is rigidly attached to and has essentially the same outside dimensions as the enclosure surface, and that has sufficient torsional rigidity to resist the bending moments th

29、at may be applied by the enclosure surface when it is deflected. A structure that is as rigid as one built with a frame of angles or channels shall be considered to have equivalent reinforcement.Constructions without a supporting frame shall be considered to include(a) a single sheet with single for

30、med flanges or formed edges;(b) a single sheet that is corrugated or ribbed;(c) an enclosure surface loosely attached to a frame (eg, with spring clips); and(d) an enclosure surface having an unsupported edge.5(Replaces p. 5, November 2001)C22.2 No. 107.2-01 Canadian Standards AssociationDecember 20

33、hstanding Clause 4.2.4.2, material either having a flammability classification not less than V-2 in accordance with CSA Standard CAN/CSA-C22.2 No. 0.17 or tested in accordance with the flame test specified in Clause 6.18.2 may be used if the components in the secondary circuit of a charger comply wi

34、th the abnormal operation test specified in Clause 6.9.3.2.4.2.5 Openings in Enclosures4.2.5.1 The enclosure shall have no openings through which the articulated probe (see Figure 1) can be inserted so as to touch moving parts (eg, fan blades) or any uninsulated live parts (including film-coated wir

35、e) operating at a voltage of more than 42.4 V peak to any other part or to ground (see Clause 4.2.7.2).4.2.5.2 The probe (see Figure 1) shall be inserted to any depth that the opening will permit, using an applied force of not greater than 4.4 N. The probe shall be rotated or angled before, during,

36、and after insertion through the opening to any necessary position, using any possible configuration. If necessary, the configuration shall be changed after insertion through the opening.4.2.5.3 Openings in the top of an enclosure that are directly over uninsulated live parts involving a risk of shoc

37、k or energy hazard shall not exceed 5 mm in any dimension unless the construction is such that straight access to those uninsulated live parts is prevented. See Figure 2 for examples of top cover designs that prevent straight access. This requirement shall not apply to a battery charger over 1.8 m h

38、igh.4.2.5.4 Openings in the vertical sides of an enclosure for 120 V cord-connected battery chargers shall be such that the accessibility probe (see Figure 3), when inserted through the opening, cannot contact uninsulated parts that can cause electric shock.4.2.5.5 A battery charger having an enclos

39、ure with openings that are located directly beneath live parts shall(a) be provided with a barrier or bottom panel complying with Clause 4.2.5.7 located beneath such live parts so as to prevent molten or flaming particles from falling on the surface on or over which the battery charger is mounted; o
