The 2021 edition introduced significant changes: en 61326-1 pdf
The standard ensures that electrical equipment does not interfere with other devices and remains immune to electromagnetic disturbances in its environment. It divides requirements into two main areas: 3 V/m RF immunity; ±4 kV contact ESD
Generic locations, similar to residential or light commercial. 3 V/m RF immunity; ±4 kV contact ESD. Industrial Locations with high-power equipment and machinery. 10 V/m RF immunity; higher surge/burst levels. Controlled Specialized areas like calibrated laboratories. 1 V/m RF immunity. 3. Performance Criteria Controlled Specialized areas like calibrated laboratories
