42、uipment, which are evaluated under the requirements for office appliances and business equipment; or portable photographic lamps and oodlights, which are evaluated under the requirements for stage and studio lighting xtures. 1.4 Electric photographic equipment intended for use in a hazardous locatio
43、n as dened in the National Electrical Code is evaluated on the basis of its compliance with the requirements in this standard, and other appropriate examination and tests to determine whether it is acceptable for the purpose. 1.5 A product that contains features, characteristics, components, materia
44、ls, or systems new or different from those covered by the requirements in this standard, and that involves a risk of re or of electric shock or injury to persons shall be evaluated using appropriate additional component and end-product requirements to maintain the level of safety as originally antic
45、ipated by the intent of this standard. A product whose features, characteristics, components, materials, or systems conict with specic requirements or provisions of this standard does not comply with this standard. Revision of requirements shall be proposed and adopted in conformance with the method
