Foreword
GB/T 34130 Powertrack Systems consists of 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 Flor
and under Floor Installation.
This Part belongs to Part 21 of GB/T 34130.
This Part was drafted as per the rules specified in GB/T 1.1-2009.
This Part adopts the re-drafting method to modify and use IEC 61534-21.2014
Powertrack Systems – Part 21. Particular Requirements for Powertrack Systems
Intended for Wall and Ceiling Mounting.
The technical differences and causes between this Part and IEC 61534-21.2014 are
as follows.
--- For the Normative References, this part has made adjustment against the
technical differences, so that adapt to the technical conditions of China; the
adjustment is mainly reflected in the Clause 2 “Normative References”; the
specific adjustments are as follows.
 Use GB/T 34130.21-2017 Powertrack Systems – Part 1. General
Requirements (IEC 61534-1.2014, MOD) to replace IEC 61534-1.2011.
This Part has made the following editorial changes.
--- Delete the notes in the IEC 61534-21.2014 that apply to other countries and
regions; such as Note to 14.2.102;
--- Since China has not adopted the standard of IEC 61534-21.2006, delete Annex
AA “Additional Test Requirements for PT Systems already Complying with IEC
61534-21.2006”.
This Part was proposed by China Electrical Equipment Industrial Association.
This Part shall be under the jurisdiction of National Technical Committee for
Standardization of Electrical Accessories (SAC/TC 67).
