This clause of Part 1 is applicable except as follows: 1.1.1 Equipment included in scope Replacement: Replace the text with the following: This part of IEC 61010 specifies safety requirements for equipment having testing or measuring circuits which are connected for test or measurement purposes to devices or circuits outside the measurement equipment itself. These include measuring 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 These testing and measuring circuits can, 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 analyse a new design. Equipment having 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.
