Foreword
GB/T 34130 “Powertrack systems” is divided into the following parts.
- Part 1. General requirements
- Part 21. Particular requirements for powertrack systems intended for wall
and ceiling mounting
- Part 22. Particular requirements for powertrack systems intended for on
floor or under floor installation
This Part is Part 1 of GB/T 34130.
This Part is drafted in accordance with the rules given in GB/T 1.1-2009.
This Part uses redraft law to modify and adopt IEC 61534-1.2014 “Powertrack
systems - Part 1. General requirements”.
The technical differences between this Part and IEC 61534-1.2014 and their
reasons are as follows.
- About normative references, this Part has made adjustments with technical
differences, to adapt to the technical conditions of China. The adjustments
are reflected in Clause 2 “Normative references”, as follows.
 USE GB/T 156 Standard voltage (GB/T 156-2007, IEC 60038.2002,
MOD) to replace IEC 60038.2009;
 USE GB/T 2099.1 Plugs and socket-outlets for household and similar
purposes - Part 1. General requirements (GB/T 2099.1-2008, IEC
60884-1.2006, MOD) to replace IEC 60884-1.2002+A1.2006;
 USE GB/T 2423.18-2012 Environmental testing - Part 2. Test methods
- Test Kb. Salt mist, cyclic (sodium chloride solution) (IEC 60068-2-
52.1996, IDT) to replace IEC 60068-2-52;
 USE GB/T 2423.55 Environmental testing for electric and electronic
products - Part 2. Test methods - Test Eh. hammer tests (GB/T
2423.55-2006, IEC 60068-2-75.1997, IDT) to replace IEC 60068-2-75;
 USE GB/T 4207-2012 Method for the determination of the proof and
the comparative tracking indices of solid insulating materials (IEC
60112.2009, IDT) to replace IEC 60112.2003;
 USE GB/T 4208-2008 Degrees of protection provided by enclosure
(IP code) (IEC 60529.2001, IDT) to replace IEC 60529.1989;
 USE GB/T 5169.14 Fire hazard testing for electric and electronic
products - Part 14. Test flames - 1 kW nominal pre-mixed flame -
Apparatus confirmatory test arrangement and guidance (GB/T
5169.14-2007, IEC 60695-11-2.2003, IDT) to replace IEC 60695-11-
2.2003;
 USE GB/T 5465 (all parts) Graphical symbols for use on electrical
equipment [IEC 60417 (all parts)] to replace IEC 60417;
 USE GB/T 9364.1 Miniature fuses - Part 1. Definitions for miniature
fuses and general requirement for miniature fuse-links (GB/T 9364.1-
2015, IEC 60127-1.2006, MOD) to replace IEC 60127-1.2006;
 USE GB/T 9797 Metallic coatings - Electroplated coatings of nickel
plus chromium and of copper plus nickel plus chromium (GB/T 9797-
2005, ISO 1456.2003, IDT) to replace ISO 1456.2009;
 USE GB/T 12599 Metallic coatings - Electroplated coatings of tin -
Specification and test methods (GB/T 12599-2002, ISO 2093.1986,
MOD) to replace ISO 2093.1986;
 USE GB/T 16927.1 High-voltage test techniques - Part 1. General
definitions and test requirements (GB/T 16927.1-2011, IEC 60060-
1.2006, MOD) to replace IEC 60060-1.2010;
 USE GB/T 17196-1997 Connecting devices - Flat quick-connect
terminations for electrical copper conductors - Safety requirements
(IEC 61210.1993, IDT) to replace IEC 61210.2010.
This Part makes the following editorial change.
- DELETE some notes in IEC 61534-1.2014 which apply to other countries
and regions, such as notes of 9.5 and 12.2.
This Part was proposed by China Electrical Equipment Industry Association.
This Part shall be under the jurisdiction of National Technical Committee 67 on
Electrical Accessories of Standardization Administration of China (SAC/TC 67).
