UL 1196:1998 pdf download Floating Waterlights
Scope
1.1 These requirements cover floating waterlights intended for use in accordance with the applicableregulations of the United States Coast Guard.
1.2 The floating waterlights covered by these requirements are intended for United States Coast Guardapproval under 46 CFR 161.010.
1.3 These requirements cover floating waterlights having solid-state electronic circuits that take powerfrom a battery and supply the power to flashtubes or incandescent lamps, causing the flashtubes or lampsto emit light at the required intensity (and, for flashing waterlights, at the required rate). The waterlightscovered are of the following types:
a)Stroboscopic Flashing – A waterlight having a flashing circuit and a xenon flashtube or theequivalent.
b)Flashing incandescent – A waterlight having a flashing circuit and an incandescent lamp.
c)Steady-Buring lncandescent – A waterlight having a circuit that provides continuous powerand an incandescent lamp.
1.4 A product that contains features, characteristics, components, materials, or systems new or difterentfrom those covered by the requirements in this standard, and that involves a risk of fire, electric shock, orinjury to persons shall be evaluated using the appropriate additional component and end-productrequirements as determined necessary to maintain the acceptable level of safety as originally anticipatedby the intent of this standard. A product whose features, characteristics, components, materials, orsystems conflict with specific requirements or provisions of this standard cannot be judged to comply withthis standard. Where considered appropriate, revision of requirements shall be proposed and adopted inconformance with the methods employed for development, revision, and implementation of this standard.
2 Units of Measurement
2.1 lf a value for measurement is followed by a value in other units in parentheses, the second value maybe only approximate. The first stated value is the requirement.
3 Components
3.1 Except as indicated in 3.2, a component of a product covered by this standard shall comply with therequirements for that component.
3.2 A component need not comply with a specific requirement that:a) lnvolves a feature or characteristic not needed in the application of the component in theproduct covered by this standard, or
b) ls superseded by a requirement in this standard.
3.3 A component shall be used in accordance with its recognized rating established for the intendedconditions of use.
3.4 Specific components are recognized as being incomplete in construction features or restricted inperformance capabilities. Such components are intended for use only under limited conditions, such ascertain temperatures not exceeding specified limits, and shall be used only under those specific conditionsfor which they have been recognized.
CONSTRUCTION
4 General
4.1 A waterlight shall be a self-contained unit and shall be constructed to be stowed in a position in whichit is extinguished,and foat in a vertically upright position and automatically emit light in the intendedmanner when in water. See Float Test, Section 10.
4.2A waterlight shall consist essentially of a case, embedding and fller material, battery, switch, electricalcircuit, flashtube or lamp assembly, globe, lanyard attachment ring, and mounting bracket. Anincandescent-type waterlight shall be provided with a spare lamp that is carried within the interior portionof the waterlight.
4.3 The size, weight, and shape of a waterlight shall permit it to be conveniently thrown overboard whenattached to a life-ring buoy by a lanyard.
4.4 The case shall be constructed to house the components necessary to produce the required lightoutput, Additional signaling devices may be incorporated inside or outside the case , if the use of suchsignaling devices does not interfere with the required light output, See Light Output Test, Section 13.
4.5 The components and connections of the electronic circuit supplying the flashtube or lamp, includingconnections to the lamp or lamp socket, shall be dip-coated, encapsulated, or otherwise protected againstmoisture, damage from leaked battery electrolyte, and movement in service.
