UL 1694 Flammability of Small Polymeric Component – Standard

UL 1694 Tests for Flammability of Small Polymeric Component Materials

UL 1694 Flammability of Small Polymeric Component – Scope
1.1 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.

1.2 This test is applicable to small components which contain materials that cannot 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.

1.3 The test is applied to ensure:
–that, under defined conditions, the test flame does not cause ignition of the small component, or
–that a combustible small component ignited by the test flame under defined conditions has a limited extent of burning and burning time, or
–that a combustible small component ignited by the test flame under defined conditions which is totally consumed has a limited burning time.

1.4 These requirements do not cover plastics when used as materials for building construction or finishing
