Laser/LED Verification

Laser and LED technology has led technological advancements in diverse industries including information technology, healthcare, entertainment, automotive, and beyond. With the prevalence of laser/LED products at home and at work, manufacturers need to minimize the optical radiation risks of their products.

At the same time, manufacturers are required to comply with regulatory standards before their laser or LED products can enter the US and global markets. Those standards include FDA/CDRH 21 CFR (laser), IEC 60825-1 (laser), and IEC 62471 (LEDs). In certain instances, manufacturers can face costly product recalls and fines if their laser/LED products are found to be non-compliant.  UL can help you avoid these problems with our years of experience in: testing, verification and regulatory standards
services.

At UL, we can also provide product verification in the form of the UL Verified Mark.

What is the UL Verified Mark Program for Laser/LED products?

UL Verification is an objective, science-based assessment that confirms the accuracy of marketing claims. The UL Verified Mark Program for Laser/LED products was created in response to industry demand for an independent verification of laser/LED radiation output level claims by a trusted test laboratory.  With this program, manufacturers are able to claim that their laser/LED products emit lower levels of radiation to help alleviate concerns from users, retailers, and others.

This unique program from UL measures optical radiation exposure from three categories of LED/Laser products.

CATEGORY A: LASER RADIATION ACCESSIBLE DURING OPERATION
Category	Verification Claim	Test Standards & Comments
A1	“Low Optical Radiation – Y% below Laser Class X Limit”	Test Program/Criteria: IEC 60825-1 testing and classification with result at least 10% below Class 1 or 2 AEL. If pulsed, must be at least 10% below all applicable Class 1 or 2 AELs. X = 1 or 2; Y = 10% or higher number

CATEGORY B: LASER RADIATION NOT INTENDED TO BE ACCESSIBLE DURING OPERATION
Category	Verification Claim	Test Standards & Comments
B1	“No operator accessible laser radiation”	Test Program/Criteria: IEC 60825-1 construction review and leakage radiation testing of enclosure resulting in no detectable levels of laser radiation externally.
B2	“Negligible operator accessible laser radiation – less than 10 µW laser power”	Test Program/Criteria: IEC 60825-1 construction review and leakage radiation testing/classification of enclosure resulting in Class 1 laser radiation externally, with a power value below 10µW.
B3	“Leakage radiation – Y% below Laser Class 1 Limit”	Test Program/Criteria: IEC 60825-1 construction review and leakage radiation testing/classification of enclosure with a result at least 10% below Class 1 AEL externally. If pulsed, must be at least 10% below all applicable Class 1 AELs. Y= 10% or higher number.

CATEGORY C: LED RADIATION ACCESSIBLE
Category	Verification Claim	Test Standards & Comments
C1	“No Photobiological LED Hazard”	Test Program/Criteria: IEC 62471 testing and risk group determination with result below all applicable Exempt Risk Group limits.
C2	“Low Optical Radiation – Y% below LED Exempt Group Limit”	Test Program/Criteria: IEC 62471 testing and risk group determination with result at least 10% below all applicable Exempt Risk Group limits. Y = 10% or higher number.
C3	“Low LED Blue Light – Y% Below Exempt Blue Light Risk Group Limit”	Test Program/Criteria: IEC 62471 testing and confirmation that the result is at least 10% below the Blue Light Exempt Risk Group limit. Y= 10% or higher number.
