16、y use - Part 1: General requirements. It was established on the basis of the 2010 edition of EN 61010-1. Amendments and revisions of Part 1 have also to be taken into account and the dates when such changes become applicable will be stated in the relevant amendment or revision of Part 1. This Part 2

17、-030 supplements or modifies the corresponding clauses in EN 61010-1 so as to convert it into the European Standard: Particular requirements for testing and measuring circuits. Where a particular subclause of Part 1 is not mentioned in this part 2, that subclause applies as far as is reasonable. Whe

18、re this part states “addition”, “modification”, “replacement”, or “deletion” the relevant requirement, test specification or note in Part 1 should be adapted accordingly. In the second edition of EN 61010-1, the requirements for testing and measuring circuits were included in Part 1 itself. In the t

19、hird edition of EN 61010-1, these requirements have been removed from Part 1 and have become the basis for the requirements in this Part 2. In addition to the requirements removed from Part 1, the following major requirements have been added to this standard. Numerous other changes have also been ma

20、de. The terminology for MEASUREMENT CATEGORY I has changed. In this Part 2, it is termed “not rated for measurements within MEASUREMENT CATEGORIES II, III, or IV”. CLEARANCES and CREEPAGE DISTANCES have been added for unmated measuring circuit TERMINALS. Requirements have been added for specialized

21、measuring circuit TERMINALS. Requirements for TRANSIENT OVERVOLTAGE limiting devices have been revised. Requirements have been revised and added pertaining to REASONABLY FORESEEABLE MISUSE of measuring circuits, including disconnection of the protective earth and usage of the equipment in a manner t

22、hat might cause arc flash. Insulation requirements for measuring circuits have been primarily located in Annex K. Annex AA has been added to describe the characteristics of MEASUREMENT CATEGORIES. Annex BB has been added to describe hazards that may be encountered when using measuring circuits. NOTE

33、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 inclu

34、de 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

35、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 th

36、e 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

37、Annex BB for considerations of HAZARDS involved in various tests and measurements. 2 Normative references This clause of Part 1 is applicable. 3 Terms and definitions This clause of Part 1 is applicable except as follows: 3.5 Safety terms Add a new definition: 3.5.101 MEASUREMENT CATEGORY classifica

39、nstallation at which the test or measurement is to be made, and some forms of energy limitation or transient protection included in the building installation. See Annex AA for more information. 4 Tests This clause of Part 1 is applicable. 5 Marking and documentation This clause of Part 1 is applicab

40、le, except as follows: 5.1.5 TERMINALS, connections and operating devices Add a new subclause: 5.1.5.101 Measuring circuit TERMINALS 5.1.5.101.1 General Except as permitted in 5.1.5.101.4: a) the RATED voltage to earth of measuring circuit TERMINALS shall be marked, and b) the RATED voltage or the R

41、ATED current, as applicable, of each pair or set of measuring circuit TERMINALS that are intended to be used together shall be marked, and c) the pertinent MEASUREMENT CATEGORY for each pair or set of measuring circuit TERMINALS or symbol 14 of Table 1 of Part 1 shall be marked as specified in 5.1.5

42、.101.2 and 5.1.5.101.3, if applicable. NOTE 1 Measuring circuit TERMINALS are usually supplied in pairs or sets. Each pair or set of TERMINALS may have a RATED voltage or a RATED current, or both, within that set, and each individual TERMINAL may have a RATED voltage to earth. Some instruments may h

43、ave a measurement RATED voltage (between TERMINALS) different from the RATED voltage to earth. Markings should be clear to avoid misunderstanding. Symbol 14 of Table 1 shall be marked if current measuring TERMINALS are not intended for connection to current transformers without internal protection (

44、see 101.2). Markings shall be placed adjacent to the TERMINALS. However, if there is insufficient space (as in multi-input equipment), the marking may be on the RATING plate or scale plate, or the TERMINAL may be marked with symbol 14 of Table 1. NOTE 2 For any set of measuring circuit TERMINALS, sy

45、mbol 14 of Table 1 does not need to be marked more than once, if it is close to the TERMINALS. Conformity is checked by inspection and, if applicable, as specified in 5.1.5.101.2 and 5.1.5.101.3, taking into account the exceptions in 5.1.5.101.4. 5.1.5.101.2 Measuring circuit TERMINALS RATED for MEA

46、SUREMENT CATEGORIES II, III or IV The relevant MEASUREMENT CATEGORY shall be marked for measuring circuit TERMINALS RATED for measurements within MEASUREMENT CATEGORIES II, III or IV. The MEASUREMENT CATEGORY markings shall be “CAT II”, “CAT III” or “CAT IV” as applicable. NOTE Marking more than one

47、 type of MEASUREMENT CATEGORY and its RATED voltage to earth is permissible (see also 5.1.5.101.1, Note 1). Conformity is checked by inspection. BS EN 61010-2-030:2010EN 61010-2-030:2010 (E) 7 5.1.5.101.3 Measuring circuit TERMINALS RATED for connection to voltages above the level of 6.3.1 Symbol 14

48、 of Table 1 shall be marked for measuring circuit TERMINALS RATED for connection to voltages above the levels of 6.3.1, but that are not RATED for measurements within MEASUREMENT CATEGORIES II, III or IV (see also 5.4.1 bb). Conformity is checked by inspection. 5.1.5.101.4 Low voltage, permanently c

49、onnected, or dedicated measuring circuit TERMINALS Measuring circuit TERMINALS do not need to be marked if a) they are intended to be permanently connected and not ACCESSIBLE (see 5.4.3 aa) and bb), or b) they are dedicated only for connection to specific TERMINALS of other equipment, or; c) it is obvious from other indications that the RATED voltage is below the levels of 6.3.1.
