IRISS IR windows are the most certified windows in the industry with IEEE (impact & load), UL, cUL, Lloyds, CSA 22.2 14-13 for industrial control equipment, DNV and ABS (American Bureau of Shipping) credentials.
Industrial users are strongly encouraged to investigate the VPFR and Platinum VPT Series of industrial-grade IR windows which are specifically designed for stability in harsh industrial environments.
UL 508 & 508A
UL 508 and UL 508A are classification for the components used on electrical panels. UL 746C is a standard requiring flammability and impact tests for polymeric materials used on electrical equipment.
CSA C22.2 No. 14-10
Canadian Standards Association shows that a product has been independently tested and certified to meet recognizable standards for safety and performance.
UL 50V applies to infrared windows and is more of a classification than a standard that applies for performance-of-build characteristics.
Lloyd’s of London
Lloyd’s provides independent, third-party approval certificates attesting to a product’s conformity with specific standards or specifications. It verifies the manufacturer’s production quality systems through a combination of design reviews and type testing.
UL 50E standard applies to enclosures for electrical equipment intended to be installed and used in non-hazardous locations.
These equivalent ratings certify enclosures for indoor or outdoor use. They protect against access to hazardous parts, ingress of foreign objects and water from rain, sleet, snow, splashing or hose directed water & ice formation damage.
Sets the impact & flammability standards for polymer materials used in electrical equipment to 1500 volts. Plastic/polymer parts of an IR window must pass flammability tests at room temperature & remain intact during an impact test performed at 0°C (32°F).
American Burea of Shipping
An ABS assessment is the pre-approval of a product for use on a variety of ABS- classed ships following a technical evaluation. Ship designers, builders and owners can select the product to be placed aboard and ABS-classed vessel.
Requirement covers metal-enclosed, low-voltage power circuit breaker switchgear assemblies containing but not limited to low-voltage power circuit breakers, switches, control, instrumentation and metering, protective and regulating equipment.
IEEE C37 20.2a.3.6
The IEEE C37 20.2 Section 3.6 is the impact and load requirement for all viewing panes installed on medium and high voltage switchgear. Panes made from crystal of glass will not pass these requirements.
