150 FOREWORD

151 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

152 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

153 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

154 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

155 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their

156 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

157 may participate in this preparatory work. International, governmental and non-governmental organizations liaising

158 with the IEC also participate in this preparation. IEC collaborates closely with the International Or ganization for

159 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

160 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

161 consensus of opinion on the relevant subjects since each technical committee has representation from all

162 interested IEC National Committees.

163 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

164 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

165 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

166 misinterpretation by any end user.

167 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

168 transparently to the maximum extent possible in their national and regional publications. Any divergence between

169 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

170 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

171 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

172 services carried out by independent certification bodies.

173 6) All users should ensure that they have the latest edition of this publication.

174 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

175 members of its technical committees and IEC National Committees for any personal injury, property damage or

176 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

177 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC

178 Publications.

179 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

180 indispensable for the correct application of this publication.

181 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

182 rights. IEC shall not be held responsible for identifying any or all such patent rights.

183 International Standard IEC 61010-031 has been prepared by IEC technical committee 66:

184 Safety of measuring, control and laboratory equipment.

185 It has the status of a group safety publication in accordance with IEC GUIDE 104.

186 IEC 61010-031 is a stand-alone standard. This future edition 3 constitutes a technical revision.

187 It consists of the second edition (2015-05), its amendment 1 (2018-05), its corrigendum 1 (2018-

188 08) and includes numerous changes.

189 This publication has been drafted in accordance with the ISO/IEC Directives, Part 2.

190 A list of all parts of the IEC 61010 series, under the general title, Safety requirements for

191 electrical equipment for measurement, control, and laboratory use, may be found on the IEC

218 d) 1.1.1: probes for voltage measurement without electrical connection to conductors have

219 been added to the scope as a new Type F and a new figure 5.

220 e) Clause 2: all normative references have been dated; new normative references have been

221 added.

222 f) Clause 3: sources for terms and definitions have been updated when relevant.

223 g) 3.1.4: definition of PROBE TIP has been modified.
224 h) 3.1.6: a definition for REFERENCE CONNECTOR has been added.

225 i) 5.1.1 and 12.2: removable parts of PROBE TIPS which bear markings are allowed.

226 j) 5.1.5: the voltage marking for MEASUREMENT CATEGORIES is no more for voltage to earth,

227 but for AC line-to-neutral or DC.
228 k) 6.4.2: requirements for unmated CONNECTORS have been modified as follows:
229 i) Table 2 has been modified and expanded,

230 ii) a calculation method for CLEARANCES of CONNECTORS above 20 kV has been defined,

231 iii) CREEPAGE DISTANCES have been aligned with CLEARANCES.

232 l) 6.4.3.1 and 6.4.3.5: requirements for IP2X PROBE TIPS with retractable sleeve have been

233 added.
234 m) 6.4.3.2: PROBE TIPS are now applicable to non-contact probe assemblies.
235 n) 6.5 has been reorganized (various editorial arrangements).

236 o) 6.5.2.3.2: values of Table 5 have been modified accordingly to Table F.2 and Table F.8 of

237 IEC 60664-1:2020.

238 p) 6.6.2: voltage tests of CLEARANCES are done without humidity preconditioning.

239 q) Fire is no longer considered as a HAZARD for probe assemblies. Requirements for spread

240 of fire have been deleted.

252 probe assemblies for electrical test and measurement
253
254
255 1 Scope and object
256 1.1 Scope
257 1.1.1 Probe assemblies included in scope

258 This part of IEC 61010 specifies safety requirements for hand-held and hand-manipulated probe

259 assemblies of the types described below, and their related accessories. These probe

260 assemblies are for non-contact or direct electrical connection between a part and electrical test

261 and measurement equipment. They may be fixed to the equipment or be detachable accessories

262 for the equipment.

263 a) Type A: non-attenuating probe assemblies that are RATED for direct connection to voltages

264 exceeding 30 V AC RMS, 42,4 V peak, or 60 V DC, but not exceeding 63 kV AC RMS or

265 DC. They do not incorporate components which are intended to provide a voltage divider

266 function or a signal conditioning function, but they may contain non-attenuating components

267 such as fuses (see Figure 1.)

268 b) Type B: attenuating or divider probe assemblies that are RATED for direct connection to

269 voltages exceeding 30 V AC RMS or 60 DC but not exceeding 63 kV AC RMS or DC. The

270 divider function may be carried out wholly within the probe assembly,
