GB/T 12501.2-1997
Scope
This standard specifies the specific requirements for direct contact and indirect contact electric shock protection, and is applicable to equipment with AC rated voltage not exceeding 1000V, rated frequency not exceeding 1000Hz and equipment with DC rated voltage not exceeding 1500V. However, the possibility of applying it to equipment with higher voltages and frequencies can be considered when developing professional standards. NOTE 1 Rated voltage is generally considered to be the rated input voltage of the equipment. For special equipment, such as low-voltage generators, the rated voltage refers to the rated output voltage. 2 The scope of GB/T 12501 is limited to not greater than AC 660V, but it has the possibility of being applied to higher voltages. 3 It should be noted that GB/T12501 does not involve protection against direct contact. The purpose of this standard is to provide guidelines for the actual implementation of the protection requirements in GB/T 12501 when the protection requirements specified in GB/T 12501 are applicable to the equipment involved in the formulation of professional standards. For these devices, individual professional standards may specify more specific or additional requirements. This standard applies GB/T 15459-1996 "Guidelines for Compiling Electrical Safety Standards". Note: Because this standard is only used as a guide for the formulation of professional standards, it is generally not sufficient to simply copy or quote this standard when formulating product safety standards.
