This Standard is applicable to radiation ftom laser products. For convenience, this Standard has been divided into three separate sections: Section One (General) and the appendices (of interest of all concemed); Section Two (Manufacturing Requirements); and Section Three (User's Guide)1*. The requirements for electrical safety are detailed in TEC 820 or other relevant EC standards.
A laser product raay 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 phenomenon; material processing; data reading and storage; transmission and display of information; etc. Such systems have found use in industry, business, entertainment, research, education and medicine. However, laser products which are sold to other manufacturers for use as components of any system for sub-sequent sale are not subject to this. Standard, since the final product will itself be subject to this Standard.
The MPE (maximum permissible exposure) values of this Standard were developed for laser radiation and do not apply to collateral radiation. The MPE values shall not be applicable to pati?nt exposure to laser radiation for the purpose of medical treatment
Nore. — Appendices A to D have been included for purposes of general guidance and to illustrate many typical cases. However, the appendices must not be regarded as definitive or exbaustive and reference should always be made to the appropriate clause(s) in Sections One to Three.
