Din En 60825-1

[Desiderato Chouinard]

IEC60825-1 is applicable to safety of laser products emitting laser radiation in the wavelength range 180 nm to 1 mm.A laser product may consist of a single laser with or without a separate power supply or may incorporate one or more lasers in a complex optical, electrical, or mechanical system. Typically, laser products are used for demonstration of physical and optical phenomena, materials processing, data reading and storage, transmission and display of information, etc. Such systems have found use in industry, business, entertainment, research, education, medicine and consumer products.Laser products that are sold to other manufacturers for use as components of any system for subsequent sale are not subject to IEC 60825-1, since the final product will itself be subject to this standard. However, if the laser system within the laser product is operable when removed from the equipment, the requirements of this Part 1 apply to the removable unit.Any laser product is exempt from all further requirements of this Part 1 if classification by the manufacturer of that product according to Clauses 3, 8 and 9 shows that the emission level does not exceed the AEL (accessible emission limit) of Class 1 under all conditions of operation, maintenance, service and failure.In addition to the hazards resulting from laser radiation, laser equipment may also give rise to other hazards such as fire and electric shock.This Part 1 describes the minimum requirements. Compliance with this Part 1 may not be sufficient to achieve the required level of product safety. Laser products must conform to the applicable performance and testing requirements of the applicable product safety standards.Where a laser system forms a part of equipment which is subject to another IEC product safety standard (e.g. for medical equipment (IEC 60601-2-22), IT equipment (IEC 60950), audio and video equipment (IEC 60065), equipment for use in hazardous atmospheres (IEC 60079), or electric toys (IEC 62115)), this Part 1 will apply in accordance with the provisions of IEC Guide 104 ) for hazards resulting from laser radiation. If no product safety standard is applicable, then IEC 61010-1 applies.In previous editions, LEDs were included in the scope of IEC 60825-1, and they may be still included in other parts of the IEC 60825 series. However, with the development of lamp safety standards, optical radiation safety of LEDs in general can be more appropriately addressed by lamp safety standards. The removal of LEDs from the scope of this Part 1 does not preclude other standards from including LEDs whenever they refer to lasers. CIE S009 may be applied to determine the risk group class of an LED or product incorporating one or more LEDs.The MPE (maximum permissible exposure) values of this Part 1 were developed for laser radiation and do not apply to collateral radiation. However, if a concern exists that accessible collateral radiation might be hazardous, the laser MPE values may be applied to conservatively evaluate this potential hazard.The MPE values are not applicable to intentional human exposure to laser radiation for the purpose of medical or cosmetic/aesthetic treatment.The objectives of this part of IEC 60825 are the following:- 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;- to reduce the possibility of injury by minimizing unnecessary accessible radiation and to give improved control of the laser radiation hazards through protective features.This second edition of IEC 60825-1 cancels and replaces the first edition published in 1993, its Amendment 1 (1997) and its Amendment 2 (2001). It constitutes a technical revision. The user's guide has been removed from this part of the IEC 60825 series and is now a separate document (Part 14). Light emitting diodes (LEDs) have been removed from the scope of this part of IEC 60825, but may still be included in other parts.This part of IEC 60825 has the status of a Group Safety Publication, in accordance with IEC Guide 104, for aspects of laser radiation pertaining to human safety.The contents of the corrigendum of August 2008 and the interpretation sheet 1 of December 2009 have been included in this copy.

IEC 60825-1:2014 is applicable to safety of laser products emitting laser radiation in the wavelength range 180 nm to 1 mm. A laser product may consist of a single laser with or without a separate power supply or may incorporate one or more lasers in a complex optical, electrical, or mechanical system. Typically, laser products are used for demonstration of physical and optical phenomena, materials processing, data reading and storage, transmission and display of information, etc. Such systems have found use in industry, business, entertainment, research, education, medicine and consumer products. Laser products that are sold to other manufacturers for use as components of any system for subsequent sale are not subject to IEC 60825-1, since the final product will itself be subject to this standard. Laser products that are sold by or for manufacturers of end products for use as repair parts for the end products are also not subject to IEC 60825-1. However, if the laser system within the laser product is operable when removed from the end product, the requirements of this Part 1 apply to the removable laser system.

2021 was a busy year for laser product safety standards. Two new European Standards (EN) were issued, adding new laser product requirements to what manufacturers currently expect from existing standards. Manufacturers will need to familiarize themselves with these new requirements as key dates for implementation approach. This article will provide some guidance and explanation on the new requirements and dates.

A second EN laser product safety standard issued in November 2021 is EN 50689, a brand-new standard that provides additional requirements for laser products defined as consumer laser products. Based on the definitions in EN 50689, a consumer laser product is defined as one intended for consumers or that is likely to be used by consumers under reasonably foreseeable conditions, even when it may not be intended for them. Therefore, manufacturers of laser products that meet this definition shall also consider EN 50689 in addition to IEC/EN 60825-1.

Examples of consumer laser products that could fall into the scope of EN 50689 include laser printers, bar code readers, laser projectors, smart phones, laser pointers, laser levels, robot vacuums and lidar.

In May 2022, EN 50689:2021 was listed as a harmonized standard under the LVD in the OJ of the European Union, and it can be used to provide presumption of conformity with the essential requirements of the LVD. Since EN 50689 is a new standard, there is no transition period from a previous version to the new version. To comply with the LVD, manufacturers can choose whether to apply this harmonized standard or parts thereof. However, if manufacturers choose not to apply the EN 50689 harmonized standard, they need to demonstrate that the products conform with essential requirements by using other means of their choice, e.g., using any existing technical specifications, including all other available standards. Harmonized standards are not mandatory, but they can simplify the process to meet the essential requirements set by the directives and regulations. For this reason, when EU harmonized standards exist, manufacturers often use them.

Furthermore, EN 50689 may be used to confirm compliance with the general safety requirement set out in the General Product Safety Directive (GPSD), which applies to consumer products when there are no specific provisions about the safety of the products in the rules of EU Law.
