57 FOREWORD
58 1) The Internatio nal Electro technical Co mmission (IEC) is a wo rld wid e o rg anization f or stand ardization co mprising
59 all natio nal electro technical committees (IEC Natio nal Co mmittees). The o b ject of IEC is to p ro mote international
60 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
61 in ad d ition to o ther activities, IEC p ub lishes International Standards, Technical Specifications, Technical Reports,
62 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
63 p rep aratio n is entrusted to technical committees; any IEC Natio nal Co mmittee interested in the sub ject d ealt with
64 may p articipate in this prep aratory wo rk. International, g overnmental and no n-governmental o rganizations liaising
65 with the IEC also p articip ate in this p rep aratio n. IEC co llab orates clo sely with the Internatio nal Org anization for
66 Stand ard izatio n (ISO) in acco rd ance with co nd itio ns d etermined b y ag reement b etween the two o rg anizatio ns.
67 2) The f o rmal d ecisions o r ag reements o f IEC o n technical matters exp ress, as nearly as p o ssible, an international
68 consensus of opinion on the relevant subjects since each technical committee has representation from all
69 interested IEC National Committees.
70 3) IEC Publications have the f orm of recommendations f or international use and are accepted by IEC National
71 Committees in that sense. While all reasonable ef forts are made to ensure that the technical content of IEC
72 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
73 misinterpretation by any end user.
74 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
75 transp arently to the maximum extent p ossible in their national and reg ional pub lications. Any d iverg ence b etween
76 any IEC Pub lication and the co rrespo nding national o r reg ional p ublication shall b e clearly ind icated in the latter.
77 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
78 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible f or any
79 services carried out by independent certification bodies.
80 6) All users should ensure that they have the latest edition of this publication.
81 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
82 memb ers o f its technical co mmittees and IEC Natio nal Co mmittees f or any p erso nal injury, p ro p erty d amage or
83 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
84 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
85 Publications.
86 8) Attention is drawn to the Normative ref erences cited in this publication. Use of the ref erenced publications is
87 indispensable for the correct application of this publication.
88 9) Attentio n is d rawn to the p ossib ility that some of the elements of this IEC Pub lication may b e the sub ject of p atent
89 rights. IEC shall not be held responsible for identifying any or all such patent rights.

167 INTRODUCTION
168 IEC 61010-1 specifies the safety requirements that are generally applicable to all equipment
169 within its scope. For certain types of equipment, the requirements of IEC 61010-1 and its
170 amendments will be supplemented or modified by the special requirements of one or more
171 standard from the IEC 61010-2 series which is/are read in conjunction with the requirements of
172 IEC 61010-1.
173 T his document and IEC 61010-2-030, IEC 61010-2-032 and IEC 61010-2-034 specify the safety
174 requirements for equipment with testing or MEASURING CIRCUITS which are connected for test or
175 measurement purposes to devices or circuits outside the measurement equipment itself.
176 According to the type of equipment and combination of functions, several IEC 61010 standards
177 are used in conjunction (see Table 0.1).

405 HAZARD OUS LIVE TERMINALS shall be anchored, fitted or designed so that internal conductors and
406 TERMINAL mechanical mountings will not work loose when the TERMINALS are tightened or
407 loosened, or when connections are made.
408 When determining the values of CREEPAGE DISTANCES for MEASURING CIRCUIT TERMINALS of a
409 hand-held multimeter intended to be connected only to a hand-held probe assembly complying
410 with IEC 61010-031:2022, or to a current sensor complying with IEC 61010-2-032:—, the
411 applicable values of CREEPAGE D ISTANCES from material group I are allowed to be applied to all
412 material groups.
413 Requirements for MEASURING CIRCUIT TERMINALS in unmated position, partially mated or mated
414 position are defined respectively in 6.6.101.2, 6.6.101.3 and 6.6.101.4. Requirements for
415 specialized MEASURING CIRCUIT TERMINALS are defined in 6.6.101.5.
416 Annex DD provides information regarding the recommended dimensions of 4 mm "banana"
417 TERMINALS.
418 6.6.101.2 MEASURING CIRCUIT TERMINALS in unmated position

427 If the hand-held multimeter is RATED to operate at an altitude g reater than 2 000 m, the value
428 of the CLEARANCE shall be multiplied by the applicable factor of Table 3.
429 Conformity is checked by inspection and measurement of CLEARANCE from the closest

431 position (see Figure 1).
432 If the CLEARANCES are less than the minimum required, they shall be verified by the following
433 AC voltage test.
434 Conformity is checked by the AC voltage test of 6.8.3.1 with a duration of at least 1 s. The
435 peak value of the AC test voltage is equal to the applicable test voltage for impulse of
436 Table K.16 for the required CLEARANCE.
437 EXAMPLE Fo r a vo ltag e of 1 500 V AC ap p lied to the co nductive p arts o f the TERMINAL, the minimum CLEARANCE
438 is 2,0 mm. Based o n Table K.16, the p eak value o f the AC test vo ltag e is 3 100 V and the AC RMS value of the
439 AC test voltage is 2 192 V.

442 given in Table K.16.
443 b) The CREEPAGE DISTANCE values shall be at least the applicable CLEARANCE values defined
444 in a) of this subclause 6.6.101.2.
445 Conformity is checked by inspection and measurement of CREEPAGE DISTANCES from the
446 closest approach of the test finger touching the external parts of TERMINAL in the least
447 favourable position.
