Page No: 27


Acceptance Criteria (or Maximum Allowable Limits): (a) No emission of flame or molten material. In case of doubt, the tests are to be conducted with the equipment placed on

a white tissue-paper-covered softwood surface. A single layer of cheesecloth is to be draped loosely over part of the equipment showing emission of flame or molten metal. The equipment is determined not to comply if the cheesecloth or the tissue paper glows or flames.

(b) Canada and U.S.: If a wire or a printed wiring board trace opens, the gap is to be electrically shorted and the test

continued until ultimate results occur. This applies to each occurrence. (c) No deformation of enclosures to cause non-compliance with Cl 2.10.3. (d) An electric strength test is made immediately (without allowing the equipment under test to cool down)* on any

REINFORCED INSULATION, or on BASIC INSULATION, or on SUPPLEMENTARY INSULATION forming part of DOUBLE INSULATION, if: (a) the CREEPAGE DISTANCE or CLEARANCE has been reduced below the value specified in 2.10; or (b) the insulation shows visible signs of damage; or (c) the insulation cannot be inspected.

In the case of BASIC INSULATION a fuse rated approximately 50% of the input rating but not greater than 1A connected in the ground circuit shall not open.*

* Canadian Requirements. Loading Requirements: (a) Four hours of max continuous output permitted by an automatic reset protector, or by a current limiting device or by a

semi-conductor device/circuitry (e.g. foldback circuitry). Note: Item (b) below is a CSA/UL D2 deviation. (b) For a fuse or manual reset device, either

i. 1 hr at the current, I, which will cause the device to open in 1 hr (value at I determined from manufacturer's specifications); or

ii. 7 hr at 110 percent of the current rating of the fuse or manual reset device with the protector in place.

Notes: i. Where a short circuit or overload of a secondary winding cannot occur or is unlikely to cause a hazard, this test is not

made. ii. Secondary windings which exceed the temperature limits but which become open circuit or otherwise require

replacement of the transformer do not constitute a failure of this test, provided that no hazard is created in the meaning of this standard.

Linear power supply (conventional or safety isolated transformer) or Ferro-resonant

transformer

Each secondary winding was loaded in turn, with the following parameters at most adverse value: primary voltage, input frequency and loads on other secondaries between zero and their specified maxima to result in the maximum heating effect.

Switch mode power supply

1. Each secondary winding was shorted in turn, with all the other windings load to their specified maxima, and

2. For NRTL: Each secondary winding was loaded in turn after rectifier (before any current limiting component, e.g. regulators). The load was adjusted until the maximum obtainable power was reached or to the point just before foldback.
