Exception: If the mounting location is fixed due to the function of the accessory and arrangement of the refrigerator, and instructions are provided co
21、vering the installation and location for the accessory, the mounting location of the accessory need not be indicated on the refrigerator. 4.6.7 As part of the investigation, accessories are to be trial-installed as necessary to determine that their installation is acceptable and that the instruction
22、s are detailed and correct. 4.7 Latch-release mechanism 4.7.1 Except as indicated in Clause 4.7.7, a door or lid permitting entry into a refrigerated storage space that has a minor dimension of 203.2 mm (8 inches) or more and a volume of 0.06 m3(2 cubic feet) or more, with any arrangement or removal
23、 of shelving, shall be constructed so that it will open easily from the inside by a force applied outwardly to the door or to a release actuator. See door latch release test, Clause 8.28. 4.7.2 With reference to Clause 4.7.1, shelving is defined as any shelf, basket, drawer, or baffle that can be re
24、moved from the refrigerator without the use of tools. 4.7.3 Interior latch-release actuators shall function with the refrigerator in its intended operating position and shall be operable from all spaces that are directly accessible when the door(s) is opened. 4.7.4 A magnetic door gasket is consider
25、ed a door-latching device. 4.7.5 A latch-release device shall not depend on an electrical source for operation. 4.7.6 A latch-release device shall be constructed so that cleaning or defrosting in accordance with the manufacturers recommendations, or normal condensation will not affect compliance wit

28、 4.8 Polymeric materials application 4.8.1 General 4.8.1.1 The requirements in Clauses 4.8.1.2 4.8.1.7, apply to polymeric materials for use in household refrigerators and freezers. These requirements do not apply to control knobs, buttons, insulating bushings, resilient mounts, clamps, wiring strap
29、s, seals including door gaskets, door handles, coated metal, food storage components such as shelves, pans, and trays or other small nonfunctional parts. As a guide, small nonfunctional parts may be considered those having an area of less than 0.093 m2(1 square foot) and that do not provide direct o
30、r indirect support of live parts. 4.8.1.2 Among the factors that are taken into consideration when judging the acceptability of a polymeric material are (1) flame resistance, (2) mechanical strength, (3) resistance to impact, (4) moisture absorptive properties, and (5) resistance to distortion at te
31、mperatures to which the material may be subjected under conditions of normal or abnormal usage. All of these factors are considered with respect to aging. 4.8.1.3 Polymeric materials used in areas where the effects of an adjacent lamp may result in distortion shall comply with the requirements in th
32、e distortion test, Clause 9.16. 4.8.1.4 Polymeric materials shall be isolated from ignition sources. Ignition sources within the unit are considered to be line-voltage wiring and any electrical components, such as coil windings, splices, open type switches, or arcing parts not enclosed in metal or a
33、 polymeric material that has been evaluated as an enclosure. Metal not less than 0.13 mm (0.005 inch) thick, fiberglass not less than 12.7 mm (0.5 inch) thick, or a polymeric material classed as 5V or as an electrical enclosure are acceptable barriers for isolation of ignition sources. Exception No.
34、 1: Impedance protected motors employing open-coil construction need not be isolated as indicated above if they comply with the burnout test impedance protected motors, Clause 9.13. Exception No. 2: Wiring need not be isolated as indicated above if it is separated from HBF, or HB materials by positi
35、ve clamping and routing at a minimum of 6.4 mm (1/4 inch). Wiring need not be isolated from 5V, V-0, V-1,V-2, HF-1, or HF-2 materials. Exception No. 3: Wiring need not be isolated if it complies with the VW-1 flame test described in the Reference Standard for Electrical Wires, Cables, and Flexible C
36、ords, UL 1581, or FT1 flame test described in Test Methods for Electrical Wires and Cables, CSA Standard C22.2 No. 0.3. Exception No. 4: Wiring need not be isolated from HB, or HBF materials if the part is additionally evaluated under conditions of the electrical disturbance test, Clause 9.14, or ho
37、t wire ignition test, Clause 9.12. 4.8.1.5 Thermal insulation located between an outer metal cabinet or door of at least 0.13 mm (0.005 inch) thickness and inner liner of a refrigerator need not be tested for flammability if (1) all entrance and exit holes for wiring, foaming, and the like located w
38、ithin this volume are sealed with caps, permagum, foil tape or the like, and (2) either the securement of the outer cabinet surfaces is inherent in the construction or the maximum spacing between screws, spot welds, or other securement means on the outer metal cabinet does not exceed 152.4 mm (6 in.
39、). Exception: Holes in the outer metal cabinet need not be sealed if (1) there are not more than two, (2) wiring is not routed through the hole, and (3) the total area is no more than 645 mm2(1 inch2). For unsealed holes larger than 645 mm2(1 inch2) the construction must be evaluated for flammabilit
40、y using the test method outlined in Clause 9.5 for HF-1 material.December 7, 2012 CSA C22.2 No. 63-93 UL 250 21 4.8.1.5A Thermal insulation located between an inner liner and an outer cabinet or door formed of: a) a non-metallic material, b) metal less than 0.13 mm (0.005 inch) thick, or c) a combin
41、ation of non-metallic material and metal less than 0.13 mm (0.005 inch) thick, need not be tested for flammability if (1) all entrance and exit holes (for wiring, foaming, and the like) located within this volume are sealed with caps, permagum, foil tape or the like, (2) either the securement of the
42、 outer cabinet surfaces is inherent in the construction, or the maximum spacing between screws, spot welds or other securement means on the outer cabinet does not exceed 152.4 mm (6 inches), (3) ignition sources (including line voltage wiring) are isolated as described in Clauses 4.8.1.4, 4.8.1.6 an
43、d 4.8.1.7, and (4) the radiant panel or Flame Spread Test, Clause 9.9, is conducted on the cabinet and/or door materials. The test of Clause 9.9 shall be conducted regardless of the size of the doors or outer cabinet, except that small trim parts, such as door end caps, ice dispenser facings, and th
44、e like, need not be tested if in total they comprise less than 5 percent of the surface area where located such as door or cabinet. Exception: Holes in the outer metal cabinet need not be sealed if (1) there are not more than two, (2) wiring is not routed through the hole, and (3) the total area is
45、no more than 645 mm2(1 inch2). For unsealed holes larger than 645 mm2(1 inch2) the construction may be evaluated for flammability using the test method outlined in Clause 9.5 for HF-1 material. 4.8.1.6 The tests that may be conducted are identified in Table 4.2. Table 4.3 specifies the tests applica
46、ble to the polymeric part being evaluated. 4.8.1.7 A lampholder or switch that controls only a light, or fan motor, ice maker, dispenser auger motor, anti-condensate heater, or similar load located within the confines of a food storage compartment, may be mounted on a polymeric part provided that: a
47、) wiring is separated or isolated from the polymeric material (see Clause 4.8.1.4); b) leads are integral to the component or are provided with insulated terminations; and c) the switch or lampholder has no uninsulated live parts after insulated terminals are connected as judged by the requirements
