Foreword
All technical contents of this standard are compulsory.
This standard replaces GB 19517-2004 "National Safety Technical Code for Electric Equipment".
Compared with GB 19517-2004, the main differences of this standard are as follows. ?€? In Application Scope of 1.1 General Provisions, the lower limit value 50V of AC voltage and lower limit value 75V of DC voltage of electrical equipment are deleted, so it makes this standard also applicable to electric product of extra-low voltage range;
?€? In Application Scope of 1.1 General Provisions, "...below 1500V AC rated voltage," is changed into "...below 1200V AC rated voltage,";
?€? "Validity period of inspection report is 12 months" in 3.3.2 is deleted; ?€? In Appendix A, newly add the relevant national standards on top of the previous 15 professional compliance standards; add the national standards relevant to 4 professions such as small fuses, industrial electric heating equipment, electrical electronic environment (fire hazard test), and low voltage surge protector; Correspondingly make the amendment to the previously-included professional standards; the compliance standards in Appendix A are increased to 331 from previous 164;
?€? Appendix B is compiled according to the requirements of GB/T 1.1. And the English that corresponds to the terms and vocabulary.
The standards listed in Appendix A are the un-dated compliance standards to meet the necessary safety element of electrical equipment and various professional products; it is normative. Appendix B is also normative.
This standard was proposed by China Electrical Equipment Industry Association. This standard shall be under the jurisdiction of National Technical Committee on Electric Safety of Standardization Administration of China (SAC/TC 25).

Introduction
The establishment of this standard is aimed to achieve optimum balance of overall safety level among people, environment and product; make the design, manufacturing, sales and application of electrical equipment to reduce the risk to life, health and property damage to maximum extent; and reach acceptable level.
The professional safety standards of various electric products must comply with this standard. And combine the necessary safety elements in technical codes WITH the characteristic of various electric products to supplement the corresponding data, provisions and special requirements.
This standard specifies the general common safety requirements of electrical equipment. The safety requirements of specific products are specified by the product standards. Both shall be used concurrently.
This standard is consisted of main text of which the essential safety elements are the technical body AND normative Appendix A which lists out various compliance standards. The relation of the main text and normative Appendix A is the relation of requirements versus the compliance and being recognized.
The electrotechnical materials such as conductor materials, insulating materials, flexible cables and flexible wires are important parts of safety essential elements. The electrotechnical material standards meeting above provisions are also listed in normative Appendix A. This standard only provides the common principle requirements to the safety essential elements such as data, limit or permissible value, technical requirements and precautionary measures. The specific and detail requirements and measures are supplemented and enhanced in compliance standards listed in normative Appendix A.
The test methods, inspection rules and methods in essential safety elements are specified by the compliance standards listed in normative Appendix A.
According to actual demand, the compliance standards listed in normative Appendix A may be increased and decreased if it is scientific, appropriate and reasonable. Under the condition that it does not compromise the overall level of the product safety, the compliance standards are not necessary to satisfy all of the essential safety elements of this standard; it may be supplemented or modified.
