This clause of Part 1 is applicable except as follows: 1.1.1 Equipment included in scope Replace the text with the following: This part of IEC 61010 specifies safety requirements for testing and measuring circuits which are connected for test or measurement purposes to devices or circuits outside the measurement equipment itself. These include measurement circuits which are part of electrical test and measurement equipment, laboratory equipment, or process control equipment. The existence of these circuits in equipment requires additional protective means between the circuit and an OPERATOR. NOTE 1 These testing and measuring circuits may, for example: – measure voltages in circuits of other equipment, – measure temperature of a separate device via a thermocouple, – measure force on a separate device via a strain gauge, – inject a voltage onto a circuit to analyze a new design. NOTE 2 Testing and measuring circuits that are not within the scope of this Part 2 are considered to be covered by the requirements of Part 1. NOTE 3 Equipment containing these testing and measuring circuits may be intended for performing tests and measurements on hazardous conductors, including MAINS conductors and telecommunication network conductors. See Annex BB for considerations of HAZARDS involved in various tests and measurements.
