UL 1694：小型聚合合成材料可燃性测试
UL 1694：Standard for Tests for Flammability of Small Polymeric Component Materials
Abstract 摘要
These requirements specify a needle-flame test to simulate the effect of small flames which may result from fault conditions within equipment in order to assess the fire hazard by a simulation technique.
This test is applicable to small components which contain materials that can not be fabricated into standardized specimens in the minimum use thickness and subjected to applicable preselection tests, such as UL 94. Test procedures specified have been determined to be applicable to small components with an overall volume of less than 2500 mm3 (0.15 in3). Test procedures may not be applicable to small components with an overall volume greater than 2500 mm3 (0.15 in3).
Test results may vary between small components which are similar in construction.Consideration should be given to the individual component construction to determine the suitability of extending results obtained for one component to other similar components.
