ANSI C136.34-2014 2014 National Electrical Manufacturers Association i AMERICAN NATIONAL STANDARD Approval of an American National Standard requires verification by ANSI that the requirements for due process, consensus, and other criteria for approval
13、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 much more than a simple majority, but not necessarily unan
14、imity. 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 respect preclude anyone, whether he has approved the standard or not, fr
15、om 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 interpretation of any American National Standard. Moreover, no person shall
16、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 name appears on the title page of this standard. CAUTION NOTICE: This
17、 American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be taken to reaffirm, revise, or withdraw this standard no later than five years from the date of approval.

22、nc./Encelium Duke Energy Florida Philips Eatons Cooper Lighting Business Philips Lumec Edison Electric Institute PNNL-Battelle EPRI ROAM/DTL EYE Lighting International of N.A., Inc. SELC Lighting Florida Power b) the level of protection in Clauses 8.1 or 8.2; c) the shield protects the photocontrol;
23、 d) the shield provides protection from horizontal projectiles to the luminaire optical assembly, ballast compartment, photocontrol, or all three; e) the shield is intended for use on luminaires mounted where handheld baseball bats (or similar) are a typical impact source. The manufacturer shall sta
24、te in the literature and on the shield or on the shield packaging the minimum mounting distance from a specific type and wattage of luminaire. Example: “This shield must not be mounted closer than 3 in. (76 mm) to a 175W mercury lamp.” 8.5 Maximum Operating Temperature If the temperature affects the
25、 shields performance, the manufacturer shall state in the literature and on the shield or shield packaging the minimum or maximum temperature at which the performance in Clauses 8.1 and 8.2 applies. 8.6 Expected Life Manufacturers shall state in the literature and on the shield or shield packaging t
26、he expected useful life of the shield when the shield is not subjected to projectile impact. 9 Luminaire Performance Alteration 9.1 Optical Performance Shields alter photometric distributions of luminaires and will reduce light output. There may be up to a 30% reduction of light output. Trapped sand
27、, dust, vermin, bird nesting materials, or imbedded projectiles may further reduce light output. In critical areas, the user must understand the implications of reduced light output and the need for routine cleaning and other maintenance. Damaged shields should be replaced on a timely basis. 9.2 Air
28、flow When properly installed according to the manufacturers instructions, the shield shall not inhibit airflow needed for luminaire cooling nor cause the luminaire to exceed its maximum temperature ratings. 10 Weight and Wind Factors 10.1 Installation Weight The weight of the shield shall be stated
29、in the literature and on the shield or shield packaging. Weight of the installed shield and luminaire should not exceed the weight rating of the pole, mast arm, and luminaire-mounting hardware. ANSI C136.34-2014 2014 National Electrical Manufacturers Association 5 10.2 Wind Resistance The manufactur
30、er shall provide effective projected area (EPA) factors for the installed shield. 11 Failure The shield is considered to have failed when: a) It no longer provides claimed minimum protection for the luminaire. b) It emits secondary projectiles when impacted. c) It reduces the shield/luminaire system
31、s lumen output below the acceptable design minimum. d) It poses a falling part hazard to people and objects below. 12 Product Marking 12.1 Identification The shield shall have a permanent label or other marking that has the following as a minimum: a) manufacturers name and catalog number; b) month a
32、nd year of manufacture, and c) the level of protection from Clauses 8.1 and 8.2. 12.2 Performance Reduction Packaging and/or field instructions shall have a note that the use of the shield will alter the light pattern and reduce lumen output of the luminaire.
