Speed evaluation of environmental-rated enclosures or end products with pre-qualified UL recognized components.

Driven by customer need, UL recently launched several new categories for environmental-rated accessories for enclosures. Enclosure-mounted components, such as window kits, can be field installed and also components that are part of a product’s or enclosure’s construction, such as handles, hinges and latches.

Choosing these components can streamline the evaluation of your environmentally-rated enclosure or end product by pre-qualifying the handle, hinge or latch for mounting on the flat surface of a Type rated or IP Code rated enclosure or product.

Using UL’s Standards for Enclosures for Electrical Equipment, Non-Environmental and Environmental Considerations, UL 50 and UL 50E respectively, components have been evaluated for their corrosion resistance, resistance to degradation caused by UV light, and for their ability to maintain the environmental seal against the flat surface of a similarly rated enclosure that they’re installed on. In addition, internal components, such as gaskets, seals and the like, have been evaluated to the requirements of these Standards, as well. This enables the end product manufacturer to focus on their product without worrying about whether they will need to find a new component source late in the product development cycle due to noncompliance of something beyond their control. And, because the handle, hinge or latch is already Recognized (Certified), material traceability for the components during Follow-up Service inspections becomes a nonissue.

While the U.S./Canadian Type rating system is the basis for the ratings of products covered under UL’s environmental-rated accessories categories, it is possible for IP Codes-using Degrees of Protection Provided by Enclosures (IP Code) IEC 60529-to be included, thus broadening global market access.
