Martin Robinson, CEO of IRISS and developer of the IR Polymer Window explains the importance and necessity of IR Window certifications. The minimum requirements necessary for certifying a product to UL standards are usually sufficient to ensure the safe and reliable operation of the product; is that statement true or false? Well, in the case of an infrared (IR) window this is not necessarily true as specific application details must be factored in before its use can be deemed ‘safe’.

UL is a US based, Nationally Recognized Testing Laboratory (NRTL) and worldwide safety consulting and certification company that performs safety testing. UL is the only organization to have a defining standard for infrared windows called UL50V. These devices are basically data collection ports for infrared inspection by thermal imaging camera that are designed to allow electrical inspections to be conducted with the utmost safety when the system is under load. They ensure the electrical enclosure remains in a ‘safe and guarded condition’ so the risk of arc flash or electrocution injury is eliminated.

Consider the bigger picture

Not all infrared windows were created equal. Hence, anyone specifying an IR window needs to dig deeper than the UL 50V standard to be 100% confident in the suitability of the chosen window type. This base line standard simply verifies that the window provides a means for passage of infrared radiation but it also carries an important caveat.

UL50V specifically states ‘meeting the requirements for this standard do not assure the window is suitable for use in any application and that suitability for continued use requires additional evaluation as to the performance characteristics necessary for the installation.’

So, what other certifications should you look for when specifying an infrared window? The following provides more detail in defining the functionality and, more importantly, the safety aspects required before attempting to modify an electrical enclosure in any way.

These are environmental standards which apply to electrical enclosures that are intended to be installed and used in non-hazardous locations. These include enclosures for indoor locations only (NEMA types 1,2,5,12, 12K and 13) and enclosures for both indoor and outdoor locations (NEMA types 3 and 3R). NEMA ratings can be self-certified when the manufacturer has third party tests to support the assigned ratings. More common to Europe are Ingress Protection (IP) ratings that can be mapped to equivalent NEMA enclosure ratings with the fundamental difference that IP ratings must be tested and certified by a third party lab.

UL 508:
These requirements cover industrial control panels intended for general industrial use, operating at 1500V or less. This equipment is intended for installation in ordinary locations, in accordance with ANSI/NFPA 70, where ambient temperatures do not exceed 40°C maximum.

UL 746C:
UL 746C is a standard to test performance of polymeric (plastic) components and identifies the ability of a window to withstand impact or flame, an important consideration in the industrial environment.

UL 1558:
UL 1558 is relevant to viewing panes and IR windows fitted into metal-enclosed, low voltage (< 600V) power circuit breaker switchgear assemblies. The standard requires the impact resistance of an assembly to be tested with the window closed; an essential criteria is that is that a 12.7mm diameter rod should not be able to pass through the window or cover.

IEEE C.37.20.2 section a.3.6:
This standard and test procedure for viewing panes mounted in electrical equipment with ratings above 1kV requires viewing panes to withstand both impact and load tests. Unlike UL this does not give any dispensation for material composition of the IR viewing window or whether or not covers are fitted.

The test is simple. It requires that both sides of the IR viewing window be subjected to impact and load and that neither side can crack, shatter or dislodge. For crystal optic based IR windows, this is a requirement that is impossible to meet.

IEC 62271-200:
This provides a controlled arc flash test for 52kV and below metal-enclosed switch gear. The test is performed at 6kV using a current of 31.5 KA for a duration of 0.5 seconds. The procedure determines the amount of pressure and heat installed components on switchgear can survive and still maintain integrity.

It should be noted that an “arc tested” or “arc resistant” rating can only be given to a completed assembly and not a single component within that assembly. Electrical cabinet designs and dimensions are infinite and we cannot and must not use data from one cabinet design to another design unless they are identical in every way.

This is the reason why components, such as IR windows can never carry a generic arc rating and must be subject to standard industry tests to confirm they meet the mechanical strengths and environment properties for each electrical cabinet or assembly to which they are being fitted.

The Occupational Health and Safety Administration (OSHA) enforces electrical safety regulations in the United States. Although OSHA has not adopted and does not mandate NFPA 70E compliance it possible you can still be cited for non-compliance?

OSHA’s authority to cite a company or an individual stems from the occupational Safety and Health Act in particular Section 5(a)(1) and 29 CFR 1910.2(g).

Section 5(a)(1) “The general Duty Clause” of the Occupational Health and Safety act, states that employers “shall furnish to each of his employees employment and a place of employment which are free from recognized hazards that are causing or are likely to cause death or serious physical harm to his employees”. This is the clause most cited by OSHA where unsafe work conditions are found to exist.

Another area where OSHA can fine companies or individuals for not abiding by national consensus standards. A consensus is a method by which an entire group of people can come to an agreement. The input and ideas of all participants are gathered and synthesized to arrive at a final decision acceptable to all.

Section 29 CFR 1910.2(g) states a “National consensus standard” means any standard or modification thereof which has been adopted and promulgated by a nationally recognized standards-producing organization under procedures whereby it can be determined that persons interested and affected by the scope or provisions of the standard have reached substantial agreement on its adoption”.

NFPA 70E is considered a national consensus standard and as such, non compliance leaves employers open for citation under Section 29 CFR 1910.2(g) if they are found not to be in compliance.

The short answer to your question is: No, there is no published ” pressure rating ” for the infrared (IR) window lens. There actually is no specific Standard existing to begin with requiring specific pressure withstand testing or assigned ratings for IR windows. However, IRISS products and lenses are tested against a minimum challenge of 950°Celsius and 25 PSI. In the case of IRISS only, this information does exist and is derived from the stunning results of much more severe testing parameters which our full product lines are subjected to–and this aspect is uniquely so for IRISS alone as our products are the most tested and certified in this industry and product category.

Additionally, the reinforced polymer optic lens design of our IR windows (part of our Electrical Maintenance Safety Device family) are the only IR window lenses on the market actually subjected to and pass the required IEEE Load & Impact testing for ‘Viewing Panes’.  One essence of this testing is the 2lb steel ball drop onto the center of the IR window lens from a specified height.

IEEE C37 20.2.a.3.6: Impact and Load: Viewing panes mounted in medium and high voltage equipment (600 volts to 38kv metal clad and 72kv station type gear) are required to withstand impact and load per IEEE C37.20.2 a.3.6. The standard specifically states that the viewing pane must withstand the impact and load from both sides (inside/outside) and the viewing pane must not “crack, shatter or dislodge.”

IRISS products are directly arc-fault tested by many of the switchgear OEM’s on assorted electrical gear, both arc rated and non-arc rated. They all consider their test formats, protocols, and resulting data to be very guarded intellectual property and they do not provide ‘Test Certificates’ upon completion of testing — it’s either a pass or fail. IRISS has never failed such a test and we consistently exceed the Standards Requirements set forth as well by the various Standards Bodies globally — IEEE, UL, cUL, CSA, LLoyds, ABS, DNV, IP65/NEMA 4, etc. IRISS’ most recent OEM testing was performed by ABB less than 1 year ago — the fault energy level tested to was 63kA-15kV-60Hz-30 Cycles, and we passed easily.


The typical temperature seen during this type of test is approximately 950°Celsius and the pressure peaks at approximately 25 PSI (depending on the design, could go higher). This is the Temperature and Pressure level resulting from a 63kA, 15kV, 30 cycles arc-fault test in arc resistant switchgear. Further, IRISS reinforced polymer IR optics easily withstand 30 PSI in sealed chamber pressure testing.

The pressure levels in the ISO bus fed pressurized Terminal Boxes in your application will never see any pressures even approaching these levels. Additionally, IRISS actually produces curved IR Inspection and Service Access Panels for mounting specifically onto pressurized and non-pressurized ISO phase bus systems alike.

It’s both relevant and vital to look at the mechanical test requirements for IR windows in the same way as for simply visual viewing windows fitted in switchgear. IRISS is the only manufacturer in this product category that tests its entire line to these much higher IEEE, and other, withstand requirements. As such, the impact, load, flammability and environmental test requirements take on a new meaning — this is why IRISS is the most recognized, certified, and universally approved IR window line globally.
