ELECTROMAGNETİC COMPATİBİLİTY (EMC) - REQUİREMENTS FOR HOUSEHOLD APPLİANCES, ELECTRİC TOOLS AND SİMİLAR APPARATUS - PART 1: EMİSSİON – PART 2: IMMUNITY PRODUCT FAMİLY STANDARD
CISPR 14-1 & CISPR 14-2 are Electromagnetic Compatibility (EMC) product family standards. Household and similar product manufacturers design their products according to CISPR 14-1 & CISPR 14-2 standards and have them tested (EMC Test). CISPR 14-1 & CISPR 14-2 standards specify the emission and immunity tests requirements for household appliances, electric tools and similar apparatus.
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.

Classification of Apparatus
Category I: equipment containing no electronic control circuitry.
Category II: mains operated equipment containing electronic control circuitry with no clock frequency higher than 15 MHz.
Category III: battery operated equipment not included in Category I.
Category IV: mains operated equipment containing electronic control circuitry with a
highest clock frequency greater than 15 MHz but lower than or equal to 200 MHz.
Category V: mains operated equipment containing electronic control circuitry with a highest clock frequency greater than 200 MHz.

Performance criteria
Performance criterion A: The apparatus shall continue to operate as intended during the test. No degradation of performance or loss of function is allowed below a performance level (or permissible loss of performance) specified by the manufacturer, when the apparatus is used as intended. 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 from what the user may reasonably expect from the apparatus if used as intended.
Performance criterion B: The apparatus shall continue to operate as intended after the test. No degradation of performance or loss of function is allowed below a performance level (or permissible loss of performance) specified by the manufacturer, when the apparatus is used as intended. During the test, degradation of performance is allowed, however no change of actual 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 from what the user may reasonably expect from the apparatus if used as intended.
Performance criterion C: Temporary loss of function is allowed, provided the function is self-recoverable or can be restored by the operation of the controls, or by any operation specified in the instructions for use.
