19、n of the interface requirements for equipment in terms of safety. It lists a number of interfaces and indicates the safety category of each listed interface. This technical report does not contain sufficient detail for conformance testing purposes, except when used in conjunction with product standa
20、rds such as IEC 60950-1 and IEC 60950-21. The equipment safety standards IEC 60950-1 and IEC 60950-21 specify the requirements for categories of circuits as SELV circuits, TNV circuits, RFT circuits and hazardous voltage circuits (among others). For stand-alone equipment it is a relatively simple ma
21、tter to determine the different categories of circuits. However, an equipment which has data port interfaces is intended to be connected to other equipment, either locally or via a network. In this case, the safety categories of the interfaces which will be connected together have to be compatible w
22、ith each other. Furthermore, the category of the interface of the remote equipment may be unknown. This is the case in systems where telecommunication equipment and data processing equipment are connected together via different types of interfaces and networks. To overcome this situation it is neces
23、sary to classify the interfaces of equipment in such configurations according to the application and to select the safety category for the interfaces of the equipment and for the type of the network. Similarly, the interfaces have to be classified for protection against damage of the equipment and o
24、f the network. Aspects of protection are dealt with in the ITU-T K series of recommendations. 3 CLC/TR 62102:2006ELECTRICAL SAFETY CLASSIFICATION OF INTERFACES FOR EQUIPMENT TO BE CONNECTED TO INFORMATION AND COMMUNICATIONS TECHNOLOGY NETWORKS 1 Scope This technical report applies to equipment inter
