NOTE: Canadian standards are mentioned for reference only. Standards are not represented here as complete equivalents to the US standards, but are referenced due to similarities in requirements. Refer to the individual standards for detailed test procedures and comparable evaluations.

Lapp cables are manufactured to comply with varying degrees of flame resistance requirements. Depending on the application, certain levels of flame resistance are necessary in order to meet specific end-use requirements. Flammability ratings are generally dictated by local or national electrical codes for the specific application.
