Foreword
All technical contents of this standard is mandatory.
GB 5226 "mechanical and electrical safety mechanical and electrical equipment" is divided into the following sections.
--- Part 1. General requirements;
--- Part 11. AC voltage greater than 1000 volts or DC voltage above 1500 volts common technique, but not more than 36 kV
condition;
Special safety and electromagnetic compatibility requirements of sewing machines, sewing units and systems;. --- Part 31
--- Part 32. General technical lifting machinery;
--- Part 33. Particular requirements for the semiconductor equipment.
This is Part 1 GB 5226's.
This section is equivalent to using IEC 60204-1.2005 "Safety of machinery Electrical Equipment Part 1. General requirements" (first
5 edition, in English).
This partial replacement GB 5226.1-2002 "Safety of machinery Electrical Equipment Part 1. General requirements."
This section on the technical content of the main differences between 5226.1-2002 GB follows.
--- expand the scope, not only for electrical and electronic equipment and machinery systems, are also applicable to programmable devices and systems;
--- motion of a machine makes provision for the protection of the ground;
--- electrical equipment leakage current is greater than 10mAa. c or d. c impose additional requirements protective earth;
--- control features increased security requirements;
--- to automatically cut off power for increased protection instructions and conditions of the TN test system makes provision;
--- deleting electronic equipment chapter (GB 5226 1 - Chapter 11 of the 2002 edition.);
--- increased protection and common conductor sectional area of indirect contact system controls two appendices.
Appendix A of this section is normative, to Appendix B, appendix C, Appendix D, Appendix E, Appendix F and Appendix G is an information appendix.

The object of IEC is to promote electrical and electronic fields related to standardization of all issues of cooperation. Required for this purpose and other activities
To, IEC publishes International Standards, Technical Specifications, Technical Reports, Specifications (PAS) and Guides publicly available (hereinafter referred to IEC
Publications). Their preparation is entrusted to technical committees, any IEC National Committee interested in the subject concerned can participate
Plus its formulation. There are liaising with the IEC national governments and non-governmental organizations, also participate in the development of standards. IEC and
International Organization for Standardization (ISO ) in close cooperation between the two organizations in accordance with agreed terms.
2) IEC technical questions about the decision or agreement, is attended by representatives of all national committees of particular interest to these technical issues
Formulated by the Commission, and the expression of international consensus on the issue as possible.
3) IEC publications recommended way for international use and in this sense accepted by the national committee. While all reasonable efforts
Force is to ensure that the content of IEC Publications is accurate, the method does not assume any end user or misinterpretation IEC
responsibility.
