CAN/CSA-E432-2-98 (R2017)

This National Standard of Canada is based on International Standard IEC 432-2:1994. 1.1 Scope This part of IEC 432 specifies the safety and the related interchangeability requirements of tungsten halogen lamps for general lighting service. It covers those tungsten halogen lamps that are used as direct replacements for conventional tungsten filament lamps as well as new tungsten halogen lamps which have no correspondence in IEC 432-1, but for which the safety and interchangeability requirements are treated by this standard in conjunction with IEC 432-1. These tungsten halogen lamps have the following characteristics: - rated wattage up to and including 250 W; - rated voltage of 50 V to 250 V inclusive; - outer envelopes with various finishes and bulb shapes as designated in ANSi C79.1; - caps B15d, B22d, E12, E14, E17, E26, E26d, E26/50x29, E27, or E27/51x39; - B51d capped lamps, without outer envelope. NOTEs 1 There is no implication that a tungsten halogen lamp used as a substitute for an incandescent tungsten filament lamp would use the same bulb shape as the original incandescent lamp. 2 There are two variations of E26 caps which are not fully compatible. E26/24 caps are used in North America and E26/25 caps used in Japan. This standard is intended to be read in conjunction with those sections of IEc 432-1 to which reference is made. This Standard applies to the safety of tungsten halogen lamps intended for use in lighting equipment, designed to be installed on branch circuits not exceeding 750 V and used in accordance with the rules of the Canadian Electrical Code (CEC), Part I. Note: Manufacturers designing products for use in Canada may find a helpful summary of the equipment-related requirements of the CEC, Part I, in CSa Publication SPE-2000.
