A soldered joint shall be

25、 mechanically secure before soldering. 4.2 A lead is considered to be mechanically secure when one or more of the following is provided: a) At least one full wrap around a terminal. b) At least one right-angle bend when passed through an eyelet or opening. c) Twisted with other conductors. 4.3 The p

26、lacing of a lead along a at surface and soldering (identied as tack soldering) is not acceptable unless it can be demonstrated that a risk of re, electric shock, or personal injury does not exist with the lead(s) detached. 4.4 Any other means of securing integral leads, for example, spade-type conne

27、ctors, wire wrapping, or the like, is to be evaluated to determine its mechanical security. 5 Component Leads 5.1 All leads intended to connect the component to the circuitry of the appliance shall be provided with a strain relief means so that stress on an external lead, or combination of leads, sh

28、all not: a) Result in damage to or displacement of the leads, or b) Reduce spacings to any connection on or inside the component. The strain-relief means shall comply with Strain-Relief Test, Section 15. 6 Lead Exit 6.1 If wires pass through an opening in a component enclosure, cover, or the like, t

29、he edges of the opening shall be smooth and well rounded, without burrs or ns that might damage the conductor insulation. 7 Bushings 7.1 A bushing, if used, shall be securely held in place. The material of the bushing shall comply with the requirements outlined by Table 11.1. 8 Corrosion Protection

30、8.1 All metal parts necessary for functioning of the component as intended shall be protected against corrosion.

31、 UL 8.2 The requirement in 8.1 applies to all parts upon which operation may depend. It does not apply to small, minor parts of iron or steel such as washers, screws, bolts, and the like that are not current carrying, if a malfunction of such unprotected parts cannot result in a risk of re, electric

32、 shock, personal injury, or inability of the component to operate, but the protection of all such parts is recommended. 8.3 Parts made of nonferrous metal, coated or treated if necessary, do not require additional protection against corrosion. 9 Insulating Materials 9.1 Insulating material employed

33、to maintain spacings between terminals involving risk of re, electric shock, or personal injury, or as the sole means of physically supporting such terminals, shall be a material that complies with the requirements outlined by Table 11.1. 10 Small-Gauge Wire 10.1 Leads of a component that are smalle

34、r than No. 24 AWG (0.21 mm 2 ) and are to be connected to the circuitry of an appliance shall be protected against mechanical damage including the effects of vibration and impact in service. 10.2 If the leads and coil windings are of dissimilar metals, the connection between them, whether welded, so

35、ldered, crimped, or the like, shall be considered with respect to mechanical security, exure, galvanic action, and strain. 11 Materials 11.1 General 11.1.1 Materials, combinations of materials, or both, excluding lead wire, shall comply with the requirements outlined by Table 11.1. 11.1.1 revised Fe

This test is described in the Standard for Polymeric Materials Short Term Property Evaluations, UL 746A. c Flammability Classication Determined by tests described in the Standard for Tests for Flammability of Plastic Materials for

41、 Parts in Devices and Appliances, UL 94. For testing a material, the samples are to be at stock (bar samples) approximately 5 inches (130 mm) long by 1/2 inch (13 mm) wide, and of the smallest thickness used; for an assembly, the samples can consist of the assembly. High-voltage transformers, deecti

42、on yokes, printed-wiring boards, terminal strips, and the like can be tested as nished parts, or test samples can be cut from nished parts. In the case of small parts that might be consumed before the test is completed, large samples of the same material can be tested provided they represent the sam

43、e or lesser thickness than the part in question. None of the larger samples is to be entirely consumed. Samples that consist of an assembly or a section thereof that are not at stock samples are to be positioned in what is considered to be the worst position in the application. The parts evaluated b
