UL 1598B:2002 pdf download Supplemental Requirements for Luminaire Reflector Kits for Installation on Previously Installed Fluorescent Luminaires
2.1.1 Except as indicated in 2.1.2, a component of a product covered by this standard shall comply withthe requirements for that component. See Appendix A for a list of standards covering components usedin the products covered by this standard.
2.1.2 A component is not required to comply with a specific requirement that:
a) Involves a feature or characteristic not required in the application of the component in theproduct covered by this standard, or
b) ls superseded by a requirement in this standard.
2.1.3 A component shall be used in accordance with its rating established for the intended conditions ofuse.
2.1.4 Specific components are incomplete in construction features or restricted in performancecapabilities. Such components are intended for use only under limited conditions. such as certaintemperatures not exceeding specified limits, and shall be used only under those specific conditions.
2.2 Units of measurement
2.2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory orapproximate information.
2.3 Undated references
2.3.1 Any undated reference to a code or standard appearing in the requirements of this standard shallbe interpreted as referring to the latest edition of that code or standard.
MECHANICAL CONSTRUCTION
3 General
3.1 After installation of a reflector kit, a luminaire shall comply with the requirements in Mechanicalconstruction,Section 2, of UL 1598.
3.2 After installation of a reflector kit, all components of the reflector kit and all components of theluminaire that were affected by the installation of the reflector kit shall be secured in place so that lampreplacement, inspection of splices to the branch-circuit supply wires, and routine maintenance will notloosen components or joints in the assembly.
3.3 Fluorescent lamps shall not be relied upon for support of any reflector kit component.
3.4 A reflector shall be secured in place by brackets, horizontal overlapping flanges, screws, or equivalentmechanical means. Friction shall not be relied upon to secure the reflector in place. The securementmeans shall be such that it will withstand any unintentional contact that occurs during lamp replacement.
4 Polymeric Materials
4.1 A polymeric material serving to complete the enclosure required in Enclosures, Subsection 2.3, of Ul1598. or providing structural support of any electrical component or of any non-electrical componentweighing more than 3 ounces (85 g) shall comply with the requirements in Polymeric materialsSubsection 2.7,of UL 1598.
4.2 A metallized polymeric reflector that is spaced within 3 inches (76.2 mm) from any lampholder, lampcontact, lampholder lead, wiring, or other electrical component (excluding the fluorescent lamps) that arebelow the metallized surface shall comply with the applicable requirements for metallized plastic parts inPolymeric Materials – Use in Electrical Equipment Evaluations, UL 746C.
4.2 revised August 22, 2002
5 Air-Handling Luminaire Reflectors
5.1 A reflector kit intended for installation in a luminaire used as an air handling register shall not impedethe intended air flow.
5.2 A nonmetallic material, adhesive, or adhesive tape used in a reflector kit intended for installation in auminaire used as an air handling register shall comply with Ai-handling luminaires, Subsection 9.2. of UL1598.
6Adhesives
6.1 An adhesive or adhesive tape shall not be relied upon to secure any part to a panel, bracket, orcomponent of a luminaire.
6.2 An adhesive or adhesive tape that complies with the requirements for temperature, humidity, andindoor cyclic conditioning for adhesives in UL 746C is able to be relied upon to secure a part of a reflectorkit to another part of a reflector kit. With regard to the temperature conditioning, a normal operatingtemperature of 90°C (194°) shall be assumed unless temperature testing of the luminaire/kit combinationindicates that a lower normal operating temperature applies. This requirement applies to all adhesivesncludina an adhesive used to secure a metal foil reflectina surface or a laminate reflectina surtace to thereflector base material.
