Test Pattern Artwork & Sample Preparation for Underwriters' Laboratories Standard U.L. 796 and U.L. 746

Standard Details

Underwrners' Laboratories Standard U.L. 796 for printed wiring boards covers test requirements for single-sided, double-,;ded, multilayer, and flexible printed wiring boards. The standard requires several qual~K:ation tests in order for a printed wiring fabricator to have his product Recognized by U.L. Various test patterns are required for the testing and U.L. 796 displays typical test patterns-Figure 7.1 and 21.1 for this purpose. U.L. does not supply copies of the test pattern artwork. Therefore each fabricator must generate his own. I n the past, each fabricator has submitted unique variations of these test patterns
