UL 796F STANDARD FOR SAFETY Flexible Materials InterconnectConstructions

UL 796F STANDARD FOR SAFETY Flexible Materials InterconnectConstructions 1 Scope 1.1 These requirements apply to flexible material printed wiring board constructions (FMIlC's) for use ascomponents in flexible，flex-to-install, rigid,and multilayer rigid-flex composite applications with andwithout stiffener and adhesive materials in devices or appliances. 1.2Together with the Standards mentioned in the Supplementary Test Procedures,Section 3, theserequirements provide data with respect to the physical,electrical，flammability，thermal，and otherproperties of the FMIC under consideration and are intended to provide guidance to the fabricator, endproduct manufacturer, safety engineers and other interested parties. 1.3 Compliance with these requirements does not indicate the product is acceptable for use as acomponent of an end product without further investigation. 1.4 The singlelayer and multilayer flexible,flex-to-install,and multilayer rigid-flex compositeconstructions addressed by these requirements consist of conductors affixed to base material, with mid-board interconnections, and cover materials. 1.5 The suitability of additional stiffener and adhesive materials，not evaluated in accordance withStiffener and adhesive (external bonding) materials, 8.10, the Stiffener bond strength test, 12.12, andFlammability tests,12.15, are subject to the applicable end-use product construction and performancerequirements. See Additional stiffener and adhesive (external bonding) materials,13.12,， for markingrequirements for FMIC's provided with additional stiffener and adhesive materials not investigated. 1.6 The requirements for rigid printed wiring boards are in the Standard for Printed Wiring Boards, uL796. 2 Units of Measurement 2.1 Values stated without parentheses are the requirement. Values in parentheses are explanatory orapproximate information. 3 Supplementary Test Procedures 3.1These requirements are intended to be used in conjunction with the following requirements orstandards: a) The Standard for Polymeric Materials - Short Term Property Evaluations,UL 746A,theStandard for Polymeric Materials - Long Term Property Evaluations, UL 746B, the Standard forPolymeric Materials - Industrial Laminates，Filament Wound Tubing，Vulcanized Fibre,and
