18、 WITHOUT PERMISSION FROM UL INTRODUCTION 1 Scope 1.1 These requirements cover shatter containment mechanisms for lamps, for use in food establishments, that are intended to prevent contamination of food. 1.2 Types of lamps covered by these requirements include incandescent, halogen, linear uorescent
19、, pin-base compact uorescent, screwbase compact uorescent, high intensity discharge (HID), and solid state. 1.3 These requirements do not apply to the lighting xtures (luminaires), lamp holders or other apparatus that support the lamps and/or shatter containment mechanism. 1.4 Some types of lamps, i
20、ncluding uorescent and HID lamps, require small amounts of mercury to efficiently function. These requirements do not cover the containment or potential release of mercury upon lamp breakage. 1.5 HID lamps may experience what is known in the industry as a non-passive failure. These requirements do n
21、ot cover the containment of glass should this occur. 2 Reference Publications 2.1 Any undated reference to a code or standard appearing in the requirements of this standard shall be interpreted as referring to the latest edition of that code or standard. 2.2 ASTM Standards ASTM G151 Standard Practic

25、that is intended to provide shatter containment. 3.2 GLOBE A type of guarded shatter container that encloses a single base lamp by attachment to the luminaire. Also referred to as a jelly jar . 3.3 GUARDED SHATTER CONTAINERS A means of shatter containment whereby a shield, guard, globe, tube, or sle
26、eve creates a barrier between the lamp and the surrounding environment, providing protection against lamp breakage or providing containment of broken lamp particles or both. 3.4 INDIRECT FOOD CONTACT Surfaces and materials of commercial food equipment not intended to be in contact with food during n
27、ormal use that are required to conform to regulations for indirect food additives. Such surfaces are determined by sanitary design and construction standards for commercial food equipment. Examples include the cavity of an oven and a refrigerated food storage compartment intended for the storage or
28、display of unpackaged foods. 3.4 effective July 15, 2014 3.5 SHATTER CONTAINMENT MECHANISMS Includes coated shatter containment lamps (3.1) and guarded shatter containers (3.3) CONSTRUCTION 4 Materials 4.1 Products shall be constructed of materials that will not cause the adulteration or contaminati
29、on of food during normal use, including conditions causing condensation. They shall be corrosion resistant, nontoxic and nonabsorbent. 4.2 Guarded shatter containers for T-8 uorescent lamps shall have a melting point no less than 370F (188C) according to Compatibility of Add-on Tube Guards with T-8

33、leanable. Surfaces of screw-shells, pins and other electrical contacts are not considered external surfaces. 5.2 Joints, internal angels, corners, and grooves 5.2.1 Permanent joints and angles shall be sealed and smooth. 5.2.2 External surfaces shall be free of open seams and gaps, recesses, protrud
34、ing ledges and dead space. Grooves shall be equal to or wider than their depth. 5.2.3 Internal corners or angles shall have smooth and continuous radii that are easily cleanable. 5.3 Fasteners 5.3.1 External surfaces shall be free of inside threads, inside shoulders, bolts and rivets. 5.3.2 Fastener
35、s that may loosen and fall out due to vibration shall be captivated or additionally secured such that they cannot enter food. PERFORMANCE 6 Pre-Impact Conditioning 6.1 General 6.1.1 Products intended for general use shall be conditioned according to 6.2. Products intended for specialized use either
36、the elevated heat of cooking equipment or the depressed temperatures of refrigerating and freezing equipment shall be conditioned according to 6.3 or 6.4, as appropriate. Once conditioned, the specimens shall then be subjected to the performance tests of Sections78 .S e eTable 6.1 for a summary of s

An additional 6 conditioned specimens and an additional 3 unconditioned samples shall be available as replacement specimens. 6.2 General use 6.2.1 One set of 12 specimens shall be loaded into a circulating air conditioning chamber. Just prior to
41、loading, the samples shall be coated on their external surfaces with a thin, transparent, uniform coating of sprayed-on melted lard. Position the samples horizontally on an elevated wire rack in the chamber with a space of at least one inch between each specimen to facilitate airow. The temperature
42、in the chamber shall be raised within three hours to the greater of: a) 140 2F (60 1C); or b) A temperature 10 2F (6 1C) greater than the average external surface temperature of the product under test, measured by means of thermocouple under normal operation. External surface temperature is obtained
43、 by operating three coated lamps or lamp protection devices with a lamp intended to be used with the product for a period of three hours at rated voltage or rated wattage, whichever results in the highest wattage. The average external surface temperature of the three specimens shall be calculated. M
44、aintain the temperature for 21 hours. Then, within three hours, lower the chamber temperature to 100 2F (37.8 1C), and 95 2 percent relative humidity. Maintain these conditions for 21 hours. This represents one complete cycle. Repeat this procedure for a total of 10 cycles. 6.2.2 At the completion o
45、f the tenth cycle, within three hours, lower the chamber conditions to 0 2F (-17.8 1C). Maintain this temperature for 21 hours, and then allow the chamber to return to ambient temperature with the chambers door closed. Remove the specimens from the conditioning chamber. There shall be no visible def
