The importance of optical radiation testing in today’s products

Whether it’s a medical device, an industrial-grade tool or a piece of laboratory equipment, many products in today’s technology-driven world employ lasers or LEDs.

Laser and LED radiation safety represents a critical concern for customers. We offer a variety of laser and LED-related services, from testing to complete evaluations to obtaining a laser or LED UL Verified Mark for your products.

In addition, our state-of-the-art laboratories around the world can evaluate products to document whether they comply with the appropriate radiation safety standards. Our team of experts can generate a wide variety of deliverables, ranging from simple optical output measurement results to IECEE CB Scheme Test Reports and Certificates.

Testing to laser radiation safety standards: FDA/CDRH 21CFR and IEC 60825-1

While lasers provide many technological benefits, they also create additional safety concerns. Laser radiation can prove hazardous to the eyes or skin under certain circumstances. Two laser product safety standards in particular — FDA/CDRH 21CFR within the U.S. and IEC 60825-1 outside the U.S. — serve the primary purpose of helping to ensure that a product has appropriate safeguards to protect those who use, maintain and service that product.

In addition, two new European laser product-related safety standards were issued in 2021:

  • EN 60825-1:2014+A11:2021, Safety of Laser Products - Part 1: Equipment Classification and Requirements: This new Amendment 11 to EN 60825-1:2014 adds new laser product safety considerations that differ from the IEC 60825-1, such as:
    • Reference to compliance with the new EN 50689 standard for consumer laser products (find more information on this standard below)
    • New testing and classification considerations for 1250-1400nm wavelengths
    • More specific emphasis on protective housings preventing human access to radiation in excess of the accessible emission limit (AEL) for Class 1
    • Inclusion of IEC 60825-1:2014 Interpretation Sheets in an annex
  • EN 50689, Safety of Laser Products - Particular Requirements for Consumer Laser Products: This new EN standard provides more requirements for consumer laser products in addition to those in EN 60825-1, such as:
    • Defining consumer laser products along with classification restrictions on such products
    • Defining child-appealing consumer laser products along with classification restrictions on such products
    • Additional testing and classification considerations for consumer laser products
    • Limitations on laser pointers
    • Additional requirements for Class 3R consumer laser products, including requirements for deliberate actions prior to laser activation, emission indicators, limitations on wavelength and peak power, and the use of the simplified (default) method for classification, i.e., C6=1, etc.
    • Requirements for labeling and user information content

Our full-service laser laboratories can perform testing to help ensure that your products meet the appropriate laser safety requirements and that you receive the necessary reports to meet U.S. FDA/CDRH and/or IEC/EN laser safety standards.

Lidar Safety

The use of Lidar technology is revolutionizing many industries, from autonomous vehicles to robotics to surveying. This laser-based technology assists with automating many common tasks such as driving, monitoring inventory, obstacle detection, and mapping. While Lidar isn’t a new development, it’s currently generating more interest as a result of these applications.

Lidar devices check the environment for objects by sending pulses of laser radiation through the air and sensing the time that elapses before the radiation reflects back. However, the laser radiation emitted can raise safety concerns about its effects on the human body — particularly the eyes.

To further complicate matters, the radiation is typically invisible and, to perform the intended function, is emitted into free space where bystanders such as pedestrians and others could be exposed without knowing it.

UL Solutions can assist Lidar manufacturers in evaluating and testing these products per the applicable laser radiation safety standards — FDA/CDRH 21CFR Part 1040 in the U.S. and IEC 60825-1 outside the U.S. These evaluations can help stakeholders and customers better understand the potential laser hazards from Lidar. Whether manufacturers want to ask UL Solutions’ laser experts questions, have us determine the potential hazard by testing and confirming the laser classification, or want UL Solutions to certify the product to these standards, we are here to help.

Our global network of laser laboratories and engineers will work to help you meet your goals. We can help you every step of the way to speed your product to market and navigate complex global standards and regulations.

Testing to LED radiation safety standards: ANSI and IEC 62471

As the use of LEDs grows in popularity along with their capabilities, so do the photobiological safety concerns associated with them. The blue light from phones and displays is a good example of these concerns. Both the American National Standards Institute (ANSI)-based RP-27 and IEC 62471 series of standards address the photobiological hazards from LEDs. We perform the testing and evaluation needed to determine a product’s Risk Group hazard classification as defined in the applicable standards.

Our optical radiation laboratories evaluate all types of LED-based products, from LEDs used in bar code imaging to the ones used in security cameras. Our reports help manufacturers document compliance with LED radiation safety requirements.

Testing to UV radiation safety standards: ANSI, ACGIH and IEC 62471

LEDs, lamps or lasers may emit ultraviolet (UV) radiation. This UV radiation is primarily invisible but can present a serious photobiological safety concern, potentially causing damage to exposed skin and eyes.

Also, in today’s environment, there are an increasing number of UV sterilization products on the market. It is important to measure and assess the UV radiation levels from these products. UL Solutions can evaluate the photobiological safety of the UV radiation to determine a product’s Risk Group classification and help ensure that it falls within specified exposure limits.

Several safety standards address potential UV radiation hazards, including the ANSI-based RP-27 series, the American Conference of Governmental Industrial Hygienists (ACGIH) Threshold Limit Values for occupational and environmental health requirements, and the IEC 62471 series of standards.

Our optical radiation laboratories can evaluate UV radiation to any of these standards. We provide results in the appropriate reporting format, helping increase turnaround times and access to global markets.
