What is ITE Product Certification Testing

Information Technology Equipment (ITE) refers to equipment whose primary function is to enter, store, display, retrieve, transmit, process, exchange, or control data and telecommunication messages (or a combination of these functions). The equipment may be configured with one or more terminal ports typically used for information transfer, and its rated voltage does not exceed 600V.

Common ITE Products

ITE includes data processing equipment, office equipment, electronic commercial equipment, telecommunications equipment, and more.

Examples: Personal computers, laptops, tablets, mice, keyboards, monitors, all-in-one PCs, printers, projectors, routers, scanners, USB flash drives, mobile hard drives, and various computer peripherals and accessories.

EMS Performance Criteria

• Performance Criterion A:
  The equipment shall continue to operate as intended without operator intervention. No degradation of performance or loss of function is allowed below a performance level specified by the manufacturer when the equipment 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, it may be derived from the product description or technical documentation, and the user has reasonable grounds to expect the equipment to meet this specification.

• Performance Criterion B:
  After the test, the equipment shall continue to operate as intended without operator intervention. After the application of the disturbance, no degradation of performance or loss of function is allowed below a performance level specified by the manufacturer when the equipment 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, after the test, the operating state shall not change, and stored data shall not be lost. If the minimum performance level or the permissible performance loss is not specified by the manufacturer, it may be derived from the product description or technical documentation, and the user has reasonable grounds to expect the equipment to meet this specification.
  
  

• Performance Criterion C:
  Temporary loss of function is allowed, provided the function is self-recoverable or can be restored by the operation of the user in accordance with the manufacturer's instructions. Functions and/or information stored in non-volatile memory or protected by a battery backup shall not be lost.
