Laser products are widely used in various fields, such as industry, medicine, entertainment, research, education, and consumer products. However, laser products can also pose serious hazards to human health and safety if not properly designed, manufactured, and used. Therefore, it is essential to have a set of standards that regulate the safety of laser products and protect users from potential risks.
One of the most important standards for laser safety is Iec 60825 1 Ed 3, which stands for International Electrotechnical Commission (IEC) Safety of laser products - Part 1: Equipment classification and requirements, Edition 3.0. This standard was published in 2014 and replaced the previous edition from 2007. It applies to all laser products that emit laser radiation in the wavelength range from 180 nm to 1 mm, which covers most of the common types of lasers.
The objectives of Iec 60825 1 Ed 3 are:
to introduce a system of classification of lasers and laser products according to their degree of optical radiation hazard in order to aid hazard evaluation and to aid the determination of user control measures;
to establish requirements for the manufacturer to supply information so that proper precautions can be adopted;
to ensure, through labels and instructions, adequate warning to individuals of hazards associated with accessible radiation from laser products; and
to reduce the possibility of injury by minimizing unnecessary accessible radiation and to give improved control of the laser radiation hazards through protective features.
The benefits of Iec 60825 1 Ed 3 are:
to provide a consistent and harmonized approach for laser safety across different countries and regions;
to enhance the quality and reliability of laser products and reduce the risk of accidents and lawsuits;
to facilitate the trade and market access of laser products by complying with international standards; and
to promote the awareness and education of laser safety among manufacturers, users, regulators, and consumers.
The main changes from the previous edition of Iec 60825 1 are :
a new class, Class 1C, was introduced for laser products that are intended to be used in contact with human skin or within body cavities;
the measurement condition 2 (\"eye loupe\" condition) was removed;
a classification of the emission of laser products below a certain radiance level that are intended to be used as replacement for conventional light sources can, as an option, be based on the IEC 62471 series;
and the accessible emission limits (AELs) for Class 1, 1M, 2, 2M and 3R of pulsed sources, particularly of pulsed extended sources, were updated to reflect the latest revision of the ICNIRP guidelines on exposure limits.
How to classify laser products according to Iec 60825 1 Ed 3?
The system of classification of lasers and laser products according to Iec 60825 1 Ed 3 is based on the degree of optical radiation hazard that they pose to human eyes and skin. The classification is determined by the maximum accessible emission level (AEL) of the laser product, which is the maximum level of laser radiation that can be emitted from the product under normal or reasonably foreseeable conditions. The AEL depends on several factors, such as the wavelength, the duration, the mode, the beam diameter, and the divergence of the laser radiation.
The classes of laser products and their AELs according to Iec 60825 1 Ed 3 are :
Class 1: Laser products that are safe under reasonably foreseeable conditions of operation. The AELs for Class 1 are derived from the exposure limits for the eye and skin for continuous wave (CW) and pulsed sources.
Class 1C: Laser products that are safe for contact application to the skin or within a body cavity under reasonably foreseeable conditions of operation. The AELs for Class 1C are derived from the exposure limits for the skin for CW and pulsed sources.
Class 1M: Laser products that are safe under reasonably foreseeable conditions of operation, but may be hazardous if the user employs optics within the beam. The AELs for Class 1M are derived from the AELs for Class 1, but with an increased beam diameter.
Class 2: Laser products that emit visible radiation (400 nm to 700 nm) and are safe for accidental exposure, but may be hazardous if viewed directly for longer than 0.25 s. The AELs for Class 2 are derived from the exposure limits for the eye for CW sources.
Class 2M: Laser products that emit visible radiation (400 nm to 700 nm) and are safe for accidental exposure, but may be hazardous if viewed directly for longer than 0.25 s or if the user employs optics within the beam. The AELs for Class 2M are derived from the AELs for Class 2, but with an increased beam diameter.
Class 3R: Laser products that are potentially hazardous under direct and specular reflection viewing, but the risk is reduced compared to Class 3B. The AELs for Class 3R are derived from a fraction (5 times for CW sources and 10 times for pulsed sources) of the exposure limits for the eye for CW and pulsed sources.
Class 3B: Laser products that are hazardous under direct and specular reflection viewing, but normally not a diffuse reflection or fire hazard. The AELs for Class 3B are derived from a fraction (0.5 times for CW sources and single pulses, and 0.05 times for multiple pulses) of the exposure limits for the eye for CW and pulsed sources.
Class 4: Laser products that are hazardous under direct, specular, and diffuse reflection viewing, and may also pose a fire hazard and produce laser-generated air contaminants. The AELs for Class 4 are above those for Class 3B.
The examples of laser products for each class are :
Class 1: Laser printers, CD players, DVD players, barcode scanners.
Class 1C: Hair removal devices, skin rejuvenation devices, dental devices.
Class 1M: Some fiber optic communication systems, some laser pointers.
Class 2: Some laser pointers, some surveying instruments.
Class 2M: Some alignment lasers, some medical lasers.
Class 3R: Some laser pointers, some industrial lasers.
Class 3B: Some medical lasers, some research lasers, some industrial lasers.
What are the requirements for laser products according to Iec 60825 1 Ed 3?
According to Iec 60825 1 Ed 3, laser products must comply with certain requirements that aim to ensure their safety and quality. These requirements include :
The manufacturer must provide information and warnings about the laser product, such as its classification, output power, wavelength, emission duration, beam diameter, divergence, hazard distance, and protective measures. The information and warnings must be given in the form of labels, instructions, manuals, and certificates.
The manufacturer must also provide protective features and safety interlocks for the laser product, such as key switches, remote interlocks, emission indicators, beam attenuators, beam shutters, beam stops, and protective housings. These features and interlocks must prevent or reduce the exposure to laser radiation in case of accidental or unauthorized access.
The manufacturer must test the laser product according to the methods and conditions specified in Iec 60825 1 Ed 3. The testing must verify the classification, the output power, the wavelength, the beam characteristics, and the compliance with the AELs and other requirements. The testing must also consider reasonably foreseeable single-fault conditions that may affect the safety of the laser product.
The manufacturer must declare that the laser product conforms to Iec 60825 1 Ed 3 and provide evidence of compliance upon request. The manufacturer must also keep records of the design, production, testing, and distribution of the laser product for at least 10 years.
