This part of IEC61000 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 16A per phase, for connection to 50Hz or 60Hz a.c. networks.
It does not apply to electrical and electronic equipment for connection to 400Hz a.c. networks. Tests for these networks will be covered by future IEC standards.
The object 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 IEC61000-4-14.
The test method documented in this part of IEC61000 describes a consistent method to assess the immunity of equipment or a system against a defined phenomenon. As described in IECGuide107, this is a basic EMC publication for use by product committees of the IEC. As also stated in Guide107, the IEC product committees are responsible for determining whether this immunity test standard should be applied or not, and, if applied, they are responsible for defining the appropriate test levels. Technical committee 77 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.
