IEC 60825的本部分提供了用于180 nm至1 mm波长范围内点对点或点对多点自由空间光数据传输的激光产品和系统的制造和安全使用要求和具体指南。本文件仅涉及系统的开放梁部分。如果设备或系统的部分包含从外壳限制延伸的光纤，则IEC 60825-2中的制造和安全要求仅适用于这些部分。本文件不适用于为材料加工或医疗等应用传输光功率而设计的系统。本文件也不适用于爆炸性环境中系统的使用（见IEC 60079）- 0). 自由空间光通信系统（FSOCS）用于自由空间光数据传输的发光二极管（LED）不属于本文件的范围。本文件涵盖了FSOCS用于自由空间光数据传输的激光器。 本文件: •提供信息，根据危害程度规定工程控制和要求、行政控制和工作实践，保护人们免受FSOCS产生的潜在危险光辐射；以及•规定了制造、安装、服务和运营组织的要求，以便建立程序并提供书面信息，以便采取适当的预防措施。 由于FSOCS（也称为光无线或自由空中信息传输系统）的性质，在其制造、安装、操作、维护和服务过程中都要小心，以确保这些系统的安全部署和使用。本文件规定了系统和/或变送器制造商对某些产品安全要求的责任，以及提供有关如何安全使用这些系统的适当信息的要求。它将安全部署和使用这些系统的责任交给安装人员和/或操作机构。它的位置 在安装和服务机构（视情况而定）的安装和服务操作期间，以及在操作机构的操作和维护职能期间，遵守安全说明的责任。 众所周知，本文件的用户可能属于上述制造商、安装商、服务机构和/或运营机构的一个或多个类别。 如果制造商根据IEC 60825-1进行的分类表明，在所有操作、维护、服务和合理可预见的故障条件下，排放水平不超过1级的可接近排放限值（AEL），则本文件不适用于激光产品。交叉引用:EN 60825-2:2004/A2:2010EN 60825-2:2004/A1:2007EN 60825-1:2014EN 60825-2（IEC 60825-2:2004）ASEN 60825-1:2014/AC:2017-06IEC 60825-1IEC 60825-2ISO 12100EN 61508（系列）IEC 60050-845IEC 60812IEC 61508（所有部分）IEC 61508（系列）IEC TR 60825- 14IEC 60079-0EN IEC 60812EN ISO 12100EN IEC 60079-0购买本文件时提供的所有现行修订版均包含在购买本文件中。

This part of IEC 60825 provides requirements and specific guidance for the manufacture and safe use of laser products and systems used for point-to-point or point-to-multipoint free space optical data transmission in the wavelength range from 180 nm to 1 mm. This document only addresses the open beam portion of the system. If portions of the equipment or system incorporate optical fibre that extends from the confinements of the enclosure(s), the manufacturing and safety requirements in IEC 60825-2 apply to those portions only. This document does not apply to systems designed for the purposes of transmitting optical power for applications such as material processing or medical treatment. This document also does not apply to the use of systems in explosive atmospheres (see IEC 60079-0). Light-emitting diodes (LEDs) employed by free space optical communication systems (FSOCSs), used for the purpose of free space optical data transmission, do not fall into the scope of this document. This document covers lasers employed by FSOCSs used for the purpose of free space optical data transmission. This document: • provides information to protect people from potentially hazardous optical radiation produced by FSOCSs by specifying engineering controls and requirements, administrative controls and work practices according to the degree of the hazard; and• specifies requirements for manufacturing, installation, service and operating organizations in order to establish procedures and provide written information so that proper precautions can be adopted. Because of the nature of FSOCSs, also known as optical wireless or free-air information transmission systems, care is taken in their manufacture as well as their installation, operation, maintenance and service to assure the safe deployment and use of these systems. This document places the responsibility for certain product safety requirements, as well as requirements for providing appropriate information on how to use these systems safely, on the manufacturer of the system and/or transmitters. It places the responsibility for the safe deployment and use of these systems on the installer and/or operating organization. It places the responsibility for adherence to safety instructions during installation and service operations on the installation and service organizations as appropriate, and during operation and maintenance functions on the operating organization. It is recognized that the user of this document may fall into one or more of the categories of manufacturer, installer, service organization and/or operating organization as mentioned above. This document does not apply to a laser product if classification by the manufacturer according to IEC 60825-1 shows that the emission level does not exceed the accessible emission limit (AEL) of Class 1 under all conditions of operation, maintenance, service and reasonably foreseeable failure.Cross References:EN 60825-2:2004/A2:2010EN 60825-2:2004/A1:2007EN 60825-1:2014EN 60825-2 (IEC 60825-2:2004) ASEN 60825-1:2014/AC:2017-06IEC 60825-1IEC 60825-2ISO 12100EN 61508 (series)IEC 60050-845IEC 60812IEC 61508 (all parts)IEC 61508 (series)IEC TR 60825-14IEC 60079-0EN IEC 60812EN ISO 12100EN IEC 60079-0All current amendments available at time of purchase are included with the purchase of this document.
