Frequently asked questions

12. Are UL 94 flammability tests (V-0, V-1, or V-2) required for wire and cable? No. The standard “Tests for Flammability of Plastic Materials for Parts in Devices and Appliances” is only applicable to plastic materials.

13. AWG versus mm²? North American agency standards recognize conductors based on diameter tolerances (AWG). European agency standards recognize conductors based on cross-section (mm²) and compliance with maximum DC resistance requirements. 14. Halogen versus non-halogen? Halogens are the elements of the seventeenth group of the periodic table: chlorine, fluorine, bromine, iodine, and astatine. Halogenated compounds include chlorides, fluorides, bromides, and iodides, which are present in many wire and cable compounds. Non-halogen wire and cable compound formulations include non-antimony based systems to replace traditional halogenated elements. Non-halogenated cable compounds do not contain any of these elements and will not release high levels of smoke or corrosive gases during a fire. 15. How do I determine ampacity of cables with conductors smaller than 18 AWG? See the following table from the latest edition of NFPA 79. To calculate based on adjustment factors (conductors and ambient temperature), refer to the tables and examples on LAPP catalog page 666. 16 Are LAPP products suitable for use inside airplanes, helicopters, drones, or other air and space travel vehicles? No. Products are not suitable for the inside of airplanes and helicopters, including drones or other direct air and space travel applications.
