Term of the day : 'Curve B (or Class B)'
Relates to conducted or radiated EMC performance, usually EN55022 which specifies two levels.
Level/Class/Curve A which is for equipment designed to operate in EMI tolerant environments such as industrial locations.
Level/Class/Curve B which is for equipment installed in EMI sensitive areas (such as domestic, commercial and light industrial).
Products which achieve curve B will always achieve curve A also it allows higher levels of conducted or radiated noise than curve B.
