GB/T 17626.29-2006 Electromagnetic compatibility Testing and Measurement Techniques. Voltage Dips, Short Interruptions and Voltage Variations on DC Input Port Immunity Test This Standard is the Part 11 of GB/T 17626.
This Standard is equivalent to IEC 61000-4-11.2004 (Ed2.0).
This Standard replaces GB/T 17626.11- 1999 Electromagnetic compatibility Testing and measurement techniques Voltage dips, short interruptions and voltage variations immunity test.
This Standard has the following main difference from GB/T 17626.11-1999. —add Electromagnetic compatibility--Guide to the drafting of electromagnetic compatibility standards in the normative reference.
—add 3 terms. 3.5 residual voltage, 3.7 calibration, 3.8 verification
—add test levels for voltage dips, and give the preferred duration for each level. —adjust the duration for short interruptions.
—Annex B is changed to describe Electromagnetic environment classes.
Annex A and Annex B of this specification are normative annexes, and Annex B and C are informative annex.
The specification is proposed and managed by China National EMC Standardization Technical Committee (SAC/TC 246).
This Standard is developed by Shanghai Electric Apparatus Research Institute (Group) Co. Ltd. and The Third Research Institute of China Electronics Technology Group Corporation. The specification is drafted by Shou JianXia, Xing Lin, Lin Jingping He Aiying, Qian Xiaohua, Cheng Liling.
This Standard replaces all the previous releases.

1 Scope
This Part of GB/T 17626 defines the immunity test methods and range of preferred test levels for electrical and electronic equipment connected to low-voltage power supply networks for voltage dips, short interruptions, and voltage variations.
This Standard applies to electrical and electronic equipment having a rated input current not exceeding 16 A per phase, for connection to 50 Hz or 60 Hz a.c. networks. It does not apply to electrical and electronic equipment for connection to 400 Hz a.c. networks. Tests for these networks will be covered by future IEC standards. The objective of this Standard is to establish a common reference for evaluating the immunity of electrical and electronic equipment when subjected to voltage dips, short interruptions and voltage variations.
NOTE Voltage fluctuation immunity tests are covered by GB/T 17626.14-2006. The test method documented in this Part of GB/T 17626 describes a consistent method to assess the immunity of equipment or a system against a defined phenomenon. As described in GB/Z 18509-2001, this is a basic EMC publication for use by product committees of the IEC. As also stated in GB/Z 18509-2001, the IEC product committees are responsible for determining whether this immunity test standard shall be applied or not, and, if applied, they are responsible for defining the appropriate test levels. The EMC Standardization Technical committee and its sub-committees are prepared to co-operate with product committees in the evaluation of the value of particular immunity tests for their products. 2 Normative references
