IEC 61326-1 Standard
ELECTRICAL EQUIPMENT FOR MEASUREMENT, CONTROL AND LABORATORY USE - EMC REQUIREMENTS - Part 1: GENERAL REQUIREMENTS
TS EN 61326-1 standard is one of the Electromagnetic Compatibility (EMC) product standards. Measurement, control and laboratory product manufacturers design their products according to TS EN 61326-1 standard and have them tested (EMC Test).
TS EN 61326-1 standard; Electrical equipment for measurement, control and laboratory covers the immunity and emission requirements regarding electromagnetic compatibility (EMC) for electrical equipment operating from an electrical grid or a battery.
The purpose of the TS EN 61326-1 standard is to specify the general characteristics and experiments (EMC Test) for electrical equipment electromagnetic compatibility (EMC) for measurement, control and laboratory.
Electromagnetic Compatibility (EMC) Tests:
Electromagnetic Compatibility Tests (EMC Test) are aimed to operate any electrical and electronic device or system without being affected by and affecting other devices or systems in the environment. EMC Tests are examined in 2 general categories as immunity and emission.

Performance criteria
Performance criterion A: During and after the test the EUT shall continue to operate as intended without operator intervention. No degradation of performance or loss of function is allowed below a minimum performance level specified by the manufacturer when the EUT is used as intended. The performance level may be replaced by a permissible loss of performance. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, then either of these may be derived from the product description and documentation, and by what the user may reasonably expect from the EUT if used as intended.
Performance criterion B: After the test, the EUT shall continue to operate as intended without operator intervention. No degradation of performance or loss of function is allowed, after the application of the phenomena below a performance level specified by the manufacturer, when the EUT is used as intended. The performance level may be replaced by a permissible loss of performance. During the test, degradation of performance is allowed. However, no change of operating state or stored data is allowed to persist after the test. If the minimum performance level (or the permissible performance loss) is not specified by the manufacturer, then either of these may be derived from the product description and documentation, and by what the user may reasonably expect from the EUT if used as intended.
Performance criterion C: During and after testing, a temporary loss of function is allowed, provided the function is selfrecoverable, or can be restored by the operation of the controls or cycling of the power to the EUT by the user in accordance with the manufacturer’s instructions.
