ANSI C136.2-2015 Page iii 2015 National Electrical Manufacturers Association AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verification by ANSI. ANSI states that the requirements for due
13、 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 agreement means signi
14、ficantly more than a simple majority, but not necessarily unanimity. Consensus requires that all views and objections be considered, and a concerted effort be made toward their resolution. The use of American National Standards is completely voluntary; their existence does not in any respect preclud
15、e anyone, whether they have 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 under no circumstances give an interpreta
16、tion 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 nam
17、e 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 Caution Notice: This American National Standard may be revised or withdrawn at any time.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 of A

30、ion of primary circuit current-carrying members of luminaires or control devices shall be rated for 600 RMS volt 60-Hz AC operation. Luminaires or control devices designed with this class of insulation are intended for use on primary circuits operated under 600 RMS volts. 5 GENERAL TESTING REQUIREME
31、NTS 5.1 TEST SAMPLES The required tests are design tests, not production tests. They shall be made on at least one sample of each DUT design or design family. Many factors can impact the dielectric withstand and electrical transient immunity performance of luminaires and control devices. DUT manufac
32、turers that intend to characterize the performance a family of products with the DUT should take care in determining the worst-case family member. 5.1.1 Optional Modular Devices DUTs designed to allow for the connection of optional modular devices may be tested with or without compatible devices. Ex
33、amples of optional modular devices include (but are not limited to) internal (to a luminaire) in-line fuses, surge protection devices (SPDs), or control devices, as well as external (to a luminaire) shorting caps and control devices. The connection of any optional modular devices shall be documented
34、 in the test report. DUTs shall always include any modular devices required for basic operation. For example, luminaires that require the use of a ballast or driver for basic operation shall not be tested without a ballast or driver. 5.1.2 Control Device Receptacles Luminaires designed with receptac
35、les that allow for the connection of a control device typically require the insertion of some device in the receptacle in order to achieve normal, powered operation. Examples of compatible control devices for such luminaires include photocontrols and shorting caps,3both of which may or may not have
36、integral electrical transient immunity protection. Such luminaires shall be tested, at a minimum, with a shorting cap that does not have integral electrical transient immunity protection. Additional testing with other configurations may be optionally performed. Test results and configurations shall
37、be documented in the test report. 5.2 TEST SETUP 3. A shorting cap is a device that provides an electrical connection between line and load when a locking-type photocontrol is not used. ANSI C136.2-2015 Page 4 2015 National Electrical Manufacturers Association 5.2.1 General All tests shall be perfor
38、med on a powered DUT that is completely assembled and wired in the conventional manner, unless otherwise noted. Any switches or other electrical controls that must be configured to achieve nominal operation shall be in the conducting, or “on,” position. Non-current-carrying parts or decorative parts
39、 not likely to become energized shall not be required to be in place. Luminaires that use lamps, light engines, or other modular light sources shall be evaluated with a lamp, light engine, or modular light source installed. For luminaires designed to work with a common or widely available class of l
40、ight sources (e.g., 100W high-pressure sodium (HPS) lamps), a representative sample can be installed, in accordance with manufacturer recommendations. The installed lamp, light engine, or modular light source catalog number shall be documented in the test report. 5.2.2 Temperature Measurements The a
41、mbient temperature in which measurements are being taken shall be maintained at 77 5.4 degrees Fahrenheit (25 3 degrees Celsius), measured at a point not more than one meter from the luminaire and at the same height as the DUT. The temperature sensor shall be shielded from direct optical radiation f
42、rom the DUT and optical radiation from any other source. 6 DIELECTRIC WITHSTAND TEST 6.1 GENERAL REQUIREMENTS 6.1.1 Test Potential Generator The dielectric withstand test potential shall be applied to the DUT using a test potential generator (commonly referred to as a hipot tester) with a two-wire (
43、high voltage, return) output configuration. The dielectric withstand test shall be performed by applying a 60-Hz AC test potential or a DC test potential to the DUT. The selection of which test potential type to apply should be dictated by the DUT construction and documented in the test report. Magn
44、etically ballasted or un-ballasted DUTs should, unless noted otherwise, be tested using the 60-Hz AC configuration, while electronically ballasted or driven DUTs should, unless noted otherwise, be tested using the DC configuration. The hipot tester shall be capable of providing 60-Hz AC test potenti
45、als at varying RMS voltage set points and DC test potentials at varying voltage set points. The hipot tester shall have a minimum capacity of 10 times the volt-amperes draw of the DUT (e.g., 1000 VA for a DUT that draws 100 VA) and shall regulate its output voltage to within 3% of the established se
46、t point. The 60-Hz AC output configuration shall produce a sinusoidal voltage waveshape such that the RMS summation of the harmonic components does not exceed 3% of the fundamental during operation of the luminaire. 6.1.2 Electrical Connections The dielectric withstand test shall be performed by app
47、lying a test potential between all DUT current-carrying terminals (electrically tied together) and accessible non-current-carrying metal parts, including the electrically conductive DUT frame or enclosure. DUTs with non-conductive frames or enclosures (e.g., shorting caps or photocontrols with polym
48、eric enclosures) shall be tested with all exterior surfaces that are accessible when installed wrapped in a metal foil; in such cases the test voltage shall be applied between the current-carrying terminals and the metal foil. 6.1.3 Electrical Disconnections Solid-state components that are not relie
49、d upon to reduce the risk of electric shock and that can be damaged by the applied test potential may be disconnected prior to testing. Circuits containing such components may be re-wired for the purpose of the dielectric withstand test in order to reduce the likelihood of component damage while retaining the representative dielectric stress on the circuit. ANSI C136.2-2015 Page 5 2015 National Electrical Manufacturers Association Examples of components that may conduct current when the test potential is applied and may the
