UV sugárzás hatása elleni tűrőképessége F1 besorolású, az UL mérései szerint hitelesítve.

Pontosan azért kell védeni, mert kültéri használatra szánták.

Az F1 az UL - Underwriters Laboratories Inc. mérései szerinti hitelesített besorolás.
Amerikai cég, de Európában is működnek, mint UL International Europe, és ha jól tudom, megvették a Bayer laboratóriumok profiljukba tartozó részét is.

UL has developed more than 800 Standards for Safety.

UL's testing programs for plastics cover plastic materials and related products for use in components and parts of end-products and appliances. Whether it is basic UL Recognition or publication of specific thermal, mechanical and electrical characteristics, UL will provide the appropriate information and service effectively and efficiently.

The plastic material characteristics published on the UL Recognition card enable users of the UL-Recognized plastic to acquire UL Certification for the product or device with a reduced test program. UL Recognition for a plastic material is not limited to the plastic manufacturer. End users can acquire UL Recognition for a plastic material or have their end products subjected to alternative tests.

(f1) Suitable for outdoor use with respect to exposure to Ultraviolet Light, Water Exposure and Immersion in accordance with UL 746C.
(f2) Subjected to one or more of the following tests: Ultraviolet Light, Water Exposure or Immersion in accordance with UL 746C, where the acceptability for outdoor use is to be determined by UL Inc.

UV Stability: The Ability to Use Outdoors
The area of greatest confusion is in the suitability of polycarbonate enclosures for outdoor application. The fact is that most PC enclosures are very well suited for outdoor use. While some PC compounds are not UV protected, others are,
and you have to check the technical data put forth by the manufacturer, supported by Underwriters Laboratories testing and certification.
