This Standard is applicable to safety of laser products. For convenience it is divided into three separate sections: Section One (General) and the Appendices; Section Two (Manufacturing requirements); and Section Three (User's guide).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 the demonstration of physical and optical phenomena; materials processing; data reading and storage; the transmission and display of information and such like. 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 subsequent sale are not subject to this Standard, since the final product will itself be subject to it.Throughout this Standard, light emitting diodes (LEDs) are included whenever the word 'laser' is used.Any laser product or LED product is exempt from all further manufacturer requirements of this Standard if -(a) classification by the manufacturer according to Clauses 3, 8 and 9 shows that the emission level does not exceed the AEL of Class 1 under all conditions of operation, maintenance, service and failure; and(b) it does not contain an embedded laser or embedded LED.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 Standard describes the minimum requirements.Where a laser system forms a part of equipment which is subject to another Australian/ New Zealand or IEC Standard for safety (e.g. for medical equipment (AS/NZS 3200.2.22), IT equipment (AS/NZS 3260), audio and video equipment (AS 3250) and equipment for use in hazardous atmospheres), this Standard will apply in accordance with the provisions of IEC Guide 104* for hazards resulting from laser radiation. However, if the laser system is operable when removed from the equipment, the requirements of this Standard will apply to the removed unit.The requirements for electrical safety are not covered in this Standard. Such requirements are detailed in AS 3100 and NZS 6200.If no product safety Standard is applicable, then IEC 1010-1 shall apply.The MPE (maximum permissible exposure) values of this Standard were developed for laser radiation rather than for 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 risk.The MPE values shall not be applicable to patient exposure to laser radiation for the purpose of medical treatment.NOTE: 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 exhaustive and reference should always be made to the appropriate clause(s) in Sections One to Three.
