UL 94:2001 pdf download Test for Flammability of Plastic Materials for Parts in Devices and Appliances
1 Scope
1.1 These requirements cover tests for flammability of plastic materials used for parts in devices andappliances. They are intended to serve as a preliminary indication of their acceptability with respect toflammability for a particular application.
1.2 The methods described in this Standard involve standard size specimens and are intended to be usedsolely to measure and describe the flammability properties of materials, used in devices and appliances.in response to heat and flame under controlled laboratory conditions, The actual response to heat andflame of materials depends upon the size and form, and also on the end-use of the product usina thematerial. Assessment of other important characteristics in the end-use application includes, but is notimited to, factors such as ease of ignition, burning rate, flame spread, fuel contribution, intensity ofburning, and products of combustion.
1.3 The final acceptance of the material is dependent upon its use in complete equipment that conformswith the standards applicable to such equipment, The flammability classification required of a material isdependent upon the equipment or device involved and the particular use of the material. The performanceevel of a material determined by these methods shall not be assumed to correlate with its performancein end-use application.
1.3 revised July 10,1998
1.4 If found to be appropriate, the requirements are applied to other nonmetallic materials.1.4 revised June 10,1997
1.5 These requirements do not cover plastics when used as materials for building construction orfinishing.
1.6 A product that contains features, characteristics, components, materials, or systems new or differentrom those covered by the requirements in this standard, and that involves a risk of fire or of electric shockor injury to persons shall be evaluated using appropriate additional component and end-productrequirements to maintain the level of safety as originally anticipated by the intent of this standard. Aproduct whose features, characteristics, components, materials, or systems conflict with specificrequirements or provisions of this standard does not comply with this standard. Revision of requirementsshall be proposed and adopted in conformance with the methods employed for development, revision, andimplementation of this standard.
