C136.27-2012 Page iii Copyright 2012 by the National Electrical Manufacturers Association AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verification by ANSI that the requ
13、irements for due process, consensus, and other criteria for approval have been met by the standards developer. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agree
14、ment means much more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and that a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any res
15、pect preclude anyone, whether he has approved the standards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the standards. The American National Standards Institute does not develop standards and will in no circumstances give an interp
16、retation of any American National Standard. Moreover, no person shall have the right or authority to issue an interpretation of an American National Standard in the name of the American National Standards Institute. Requests for interpretations should be addressed to the secretariat or sponsor whose
17、 name appears on the title page of this standard. Caution Notice: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken periodically to reaffirm, revise, or withdraw this standard. Purchasers
18、of American National Standards may receive current information on all standards by calling or writing the American National Standards Institute.

The requirements in this standard are limit
24、ed to general attributes of tunnel luminaires due to the wide variety of designs possible. 2 NORMATIVE REFERENCES This standard incorporates by undated reference, provisions from other publications.

C136.27-2012 Page 2 Copyright 2012 by the National Electrical Manufacturers Association 4 TERMINAL BLOCKS A terminal block with a minimum of two line-side pressure-type wire connectors having slotted-head screws shall be securely mounted in the luminaire so that inc
32、oming conductors will clear all internal accessories. Each connector shall accept only one conductor (either solid or stranded), from 6 American Wire Gauge to 14 American Wire Gauge copper/aluminum. 5 WIRING All internal components shall be assembled and pre-wired so that the luminaire can be energi
33、zed by line connections at the terminal block, unless otherwise specified. Multi-wattage or multi-voltage luminaires will be pre-wired in accordance with customer specifications. 6 LATCHING AND HINGING If the luminaire is equipped with latches to secure the lens door and to permit access to the lamp
34、 compartment, then the latches shall be operable by persons wearing protective gloves and using a maximum of one tool. If the luminaire is equipped with a sealed removable lamp compartment, it shall be removable by persons wearing protective gloves and using a maximum of one tool. All screws used to
35、 either gain access to the lamp compartment or to remove the sealed lamp compartment shall be captive. Latches or any other objects attached to the luminaire shall be so designed to prevent the snagging of flapping tarpaulins, ropes, etc. from vehicles. The luminaire latching shall not open during v
36、ibration testing. 7 VOLTAGE CLASSIFICATION The luminaires shall be of the 250-volt or 600-volt classification, whichever is applicable, as defined in ANSI C136.2. 8 LAMP SOCKET Metallic parts of sockets shall be constructed of corrosion resistant material. Sockets shall be constructed so as to preve
37、nt lamps from shaking loose due to vibration. 8.1 Medium Or Mogul Socket Luminaires that are equipped with either a medium or a mogul socket shall meet the requirements of ANSI C136.11. 8.2 Fluorescent Lamps Luminaires that are intended for use with fluorescent lamps shall have sockets meeting the r
38、equirements of ANSI C81.61. Lamp supports may be necessary depending on socket design. 8.3 Low-Pressure Sodium Lamps Luminaires that are intended for use with low-pressure sodium lamps shall have sockets that meet the requirements of ANSI C81.61. Lamps supports are necessary for low-pressure sodium
39、lamps. 9 OPTICAL ASSEMBLY The optical assembly shall be effectively sealed by conforming gaskets to minimize the entrance of atmospheric contaminants. While the luminaire is being opened, the gasket shall remain securely attached to the intended surface. Silicone gaskets shall not out-gas, which wil
40、l contaminate the optical assembly. The lens door or sealed removable lamp compartment shall prevent the entrance of water into the optical assembly when the luminaire is subjected to the water spray test as described in clause 17.2 Water Spray Test. If applicable, venting of the optical assembly sh
41、all be through a filtered orifice that will prevent soot, dirt, water, and other contaminants from entering the optical assembly. The optical assembly seal shall not leak due to the expansion and contraction of the luminaire components over a temperature range from -20 to +40C. 10 LENS The luminaire
42、 shall be equipped with a lens made of material that is resistant to thermal shock, ultraviolet light, exhaust fumes, soot, and other chemicals found in a tunnel atmosphere. Soot and tunnel dirt shall C136.27-2012 Page 3 Copyright 2012 by the National Electrical Manufacturers Association be readily
43、cleaned from the lens using soap and water under pressure. The lens, lens frame, and gasket system shall be constructed to minimize stresses on the lens due to the different coefficient of thermal expansion of the lens and lens frame. The lens assembly shall not warp or crack over an ambient tempera
44、ture range from -20 to + 40C for operating and non-operating conditions. If the lens is constructed out of a polymeric material at a pressure of 4.55 bars (66 psi) it shall have a minimum temperature deflection rating 25C higher than the temperature that the lens will attain when the fixture is oper
45、ated in an ambient temperature of 25C in still air. If the fixture will be cleaned with a heated cleaning solution, the temperature rating of the lens material shall be 10C higher than the temperature of the cleaning solution. 11 VIBRATION The fixture shall meet the requirements of ANSI C136.31 for
46、vibration test levels in the high application category. The luminaire latching shall not open during vibration testing. 12 POWER SUPPLY The term power supply as used in this document includes any required interface device between the supply voltage and lighting device. The power supply shall meet th
47、e requirements of ANSI C136.2 and ANSI C82.4 for HID equipment, ANSI C82.1 for fluorescent equipment, ANSI C136.38 for induction equipment and ANSI C136.37 for solid state lighting equipment. The power supply shall start and operate the specified lamp over an ambient temperature range from -20 to +4
48、0C. 13 MATERIALS AND PROTECTIVE COATINGS Materials and protective coatings for the luminaire shall individually and as a system be resistant to atmospheric conditions, including the corrosive and erosive action of conditions of service encountered in roadway tunnels. When dissimilar materials are in
49、 contact, the effects of corrosion shall be considered. All latches, hinges, screws, and other external/internal hardware shall be made out of stainless steel or other materials which are resistant to corrosion from exhaust fumes, salt, dirt, and soot as found in tunnels. The luminaire shall be subjected to the ASTM B117 Salt Spray (Fog) Test for 1,000 h without altering the performance and serviceability of the luminaire. The luminaire and its associated mounting hardware shall not be corroded by the chemica
