1 Scope

GB/T 10320-2011 is the Chinese national standard on electrical safety of laser equipment and installatins, in the field of electronics. The /T suffix marks it as a recommended standard: it is not compulsory by itself, but it becomes binding as soon as a contract, a tender or a customer specification calls it up - which in practice is how most foreign buyers meet it. It was issued on 30 December 2011 by the General Administration of Quality Supervision, Inspection and Quarantine of the People's Republic of China; Standardization Administration of China, and has been in force since 1 May 2012. Classification: ICS 31.260, CCS L51. This page is published from the official record of the standard held by the Chinese standards administration: the identification, the dates, the classification and the issuing body are taken from there. The clause text, the tables and the numeric limits are in the document itself, which is delivered complete in English translation.

This standard specifies the requirements for laser safety facilities and equipment and related electrical part test methods, given the pre-basic electrical safety Directory of preventive measures. This standard applies to the safety requirements of laser equipment and facilities as defined herein and the relevant test methods in line with the purpose of the following Respect for the user equipment to provide reliable protection.

a) direct and indirect contact;

b) high temperature effects (fire hazard);

c) burst and implosion;

d) the role of toxic or corrosive substances. This standard does not apply to laser equipment and facility work at safety extra low voltage electrical hazards of electrical part of the direct and indirect Reach protection; it does not apply to the entire apparatus containing a laser components (such as medical equipment, office machines and provided for use in hazardous environments Standby). These devices should be subject to the other electrical safety standards. However, if the laser is removed from the device is still working out the demolition of the laser Shall comply with the requirements of this standard. This standard does not apply to the development or in the design of laser equipment and facilities. This standard does not apply to the use of the laser radiation generated by laser equipment; nor does it explain radiation protection measures. But anti-laser radiation When connected to the protection device and electrical equipment, according to the test shall be specified in this standard to estimate its electrical safety.
