UL Recognized
The US institute Underwriters Laboratories (UL) is an independent organisation that examines, tests and certifies products with regard to their safety. UL develops procedures and standards to test the safety of products, devices, materials, parts, components, systems and equipment. Since 1894, UL's safety standards have included design recommendations as well as testing and design requirements for various products. UL is also a globally recognised test laboratory and one of the most widely accepted certification marks.
The UL mark appears on 22 billion products in the USA every year. The UL/CSA Recognised mark is awarded to subcomponents of larger systems. In this case, only components that are not intended for a single, precisely defined installation or application are certified. Cables for applications that cannot be fully described in terms of standards are certified according to UL-Recognised (AWM).
Cables for use in energy chains can be mentioned here as an example: These are so varied, complex and diverse that a complete standardised description is impossible. This is where UL-Recognised approval comes into play. This offers cable developers a modular system of various approved insulation, jacket and construction options. Ideally, cable manufacturers use this to create a combination that can be used precisely for a specific customer application, i.e. that works.
The construction kit consists of various inner and outer styles with which a cable can be assembled. The different styles are defined in terms of voltage level, flame resistance, temperature range, etc. Depending on the application, the different styles can then be mixed. The inner style defines the requirements for the core insulation and the outer style for the outer jacket.
For our chainflex® cables, this means the following:
Over 1000 of our chainflex® cables have UL certification. They are manufactured in accordance with the appropriate UL styles and can therefore be installed in the USA and in some cases in Canada without any problems. We comply with the approval guidelines and certification processes.
