22、#2 Phillips screwdriver, wrench, or Allen key. 4.3 Vandal shields (hereinafter referred to as “shield”) A system designed to reduce the likelihood of projectile or direct impact damage to luminaires. The shield includes the optical component(s), mounting devices, and hardware. 5 Mounting 5.1 Shields
23、 shall be intended to be installed without drilling, cutting, or structurally modifying luminaire or mast arm. 5.2 Special tools shall not be needed to install or remove a shield, unless specified by the user. 5.3 A shield shall allow access, without the use of special tools, to lamp, ballast, photo
24、control, and starting aid, if so equipped. 5.4 When properly installed according to the manufacturers instructions, the shield shall remain attached and not be damaged when subject to the vibration test in ANSI C136.31. After the test, the shield shall meet original claimed specifications. Copyright

26、allow viewing of the luminaire labeling as defined in ANSI C136.15. 5.6 Installation or mounting instructions shall be provided with each shield. 6 Materials 6.1 Materials and protective coatings used for the shield shall individually, and as a system, be resistant to atmospheric conditions, includi
27、ng the corrosive and erosive action of conditions of service encountered in industrial, agricultural, and seaboard areas. 6.2 Depending on the type of light source protected, materials used in vandal shields will be exposed to heat from the luminaire and infrared and ultraviolet light from the lamp.
28、 Materials thus exposed must not degrade mechanically or optically during the manufacturers claimed life of the shield. When used on some high-intensity discharge luminaires, the useful life of the shield may be less than that of the lamp or luminaire. 6.3 Materials used must be compatible with stan
29、dard luminaire and luminaire attachment materials, including aluminum, stainless steel, fiberglass, and galvanized steel. 6.4 Materials shall be suitable for at least -40 to +70 C operation. However, the manufacturer may limit the temperature range over which the shield will provide a specified leve
30、l of protection. See Clause 8.6. 6.5 When required by the user to be flame retardant, the shield shall be made of material(s) that is (are) UL 94 rated V2 or better. 7 Maintenance 7.1 The shield shall be removable and re-usable or otherwise designed for easy cleaning. 7.2 If the shield is designed t
31、o be partially removed for cleaning or re-lamping, its design shall prevent it from striking the luminaire, mast arm, or pole when so removed. 7.3 The shield shall not trap water.

33、ellets, and similar. Unless otherwise specified, performance is defined when the shield is mounted on the luminaire at 25 ft (7.6 m) mounting height. 8.2 If the manufacturer claims additional protection above that of Clause 8.1, the level of protection shall be one or more of the following: a) Up to
34、 and including .22 caliber rimfire bullets. b) The UL 752 rating system. c) The impact energy protection level in ft-lb (Newton-meters). 8.3 The shield or any part of the shield shall not come loose or create secondary projectiles after impact. 8.4 The Manufacturer shall state in the literature and
35、on the shield or shield-packaging if: a) The shield protects the optical assembly, the ballast compartment, or both. b) The level of protection in Clauses 8.1 or 8.2. c) The shield protects the photocontrol. d) The shield provides protection from horizontal projectiles to the luminaire optical assem
36、bly, 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. 8.5 The manufacturer shall state in the literature and on the shield or on the shield packaging the minimum mounting di
37、stance from a specific type and wattage of luminaire. Example: “This shield must not be mounted closer than 76 mm (3 in.) to a 175 W mercury lamp.” 8.6 If the temperature affects the shields performance, the manufacturer shall state in the literature and on the shield or shield packaging the minimum
38、 or maximum temperature at which the performance in Clauses 8.1 and 8.2 apply. 8.7 Manufacturers shall state in the literature and on the shield or shield packaging the expected useful life of the shield when the shield is not subjected to projectile impact. 9 Luminaire performance alteration 9.1 Sh
39、ields alter photometric distributions of luminaires and will reduce light output. There may be up to a Copyright National Electrical Manufacturers Association Provided by IHS under license with NEMALicensee=NASA Technical Standards 1/9972545001 Not for Resale, 04/19/2007 09:46:13 MDTNo reproduction

Trapped sand, 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
41、and the need for routine cleaning and other maintenance. Damaged shields should be replaced on a timely basis. 9.2 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 temp
42、erature ratings. 10 Weight and wind factors 10.1 The weight of the shield shall be stated 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. 10.2 The manufac
43、turer 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 sys
44、tems lumen output below the acceptable design minimum. d) It poses a falling part hazard to people and objects below. 12 Labeling 12.1 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 and year of manufact
45、ure. c) The level of protection from Clauses 8.1 and 8.2. 12.2 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.
