oSIST prEN IEC 60730-2-10:2026 is a SIST standard identical to prEN IEC 60730-2-10:2026. It gives particular requirements for automatic electrical motor-starting relays used in household and similar equipment, including appliances, building automation equipment, and other public-use applications. Engineers, quality managers, and buyers use it together with IEC 60730-1 when selecting, designing, testing, or specifying these relays.
What does oSIST prEN IEC 60730-2-10:2026 specify?
oSIST prEN IEC 60730-2-10:2026 specifies construction, operation, and testing requirements for motor-starting relays. It supplements IEC 60730-1 and then adapts the general rules for this relay type.
The standard applies to relays used to control the start winding of single-phase motors in household and similar applications. It also covers use in appliances, HBES/BACS equipment, smart-enabled equipment, and equipment used by the public, such as in shops, offices, hospitals, farms, and commercial and industrial applications.
The document is organized as a Part 2 standard with clauses 1 to 26, plus Annex H and regional annexes Q, R, S, and T. Most clauses point back to Part 1, and the special requirements are concentrated in the scope, technical information, heating, endurance, abnormal operation, and functional safety sections.
| Annex | What it covers |
|---|---|
| H | Functional safety requirements |
| Q | Regional differences for CENELEC member countries |
| R | National differences for the United States of America |
| S | National differences for Japan |
| T | National differences for Canada |
What are the key requirements of oSIST prEN IEC 60730-2-10:2026?
oSIST prEN IEC 60730-2-10:2026 mainly does two things: it defines what counts as a motor-starting relay, and it changes the Part 1 tests so they suit this relay type. For a manufacturer, that means the product description, test setup, and declared operating data have to match the relay’s real use in a motor circuit.
Applicability and product definition
The standard covers electrically operated controls intended to connect the main winding and the auxiliary starting winding of a single-phase motor. That matters because the relay is evaluated as part of the motor-starting function, not as a general switching device.
It applies to AC- or DC-powered equipment up to the stated voltage limits, and it also includes relays used with electricity, gas, oil, solid fuel, solar thermal energy, or combinations of these. In practice, this means the relay can appear in a wide range of appliances and control systems, but the document still focuses on the motor-starting role.
The document excludes general purpose relays, contactors, and motor starters covered by IEC 60947, and it excludes mechanically operated motor-starting devices. If a product is intended for industrial process applications only, another relevant equipment standard normally takes priority.
Technical information and classification
Clause 5 and Table 1 require the manufacturer to declare the technical information needed to apply the tests. This includes the purpose of the control, the type of control, and the current and operating data used to set up the evaluation.
The table also distinguishes control types such as voltage sensing, current sensing, PTC, and thermally operated versions. That matters because the test program and safety assessment depend on how the relay senses and switches the motor circuit.
Heating and endurance
Clause 16 modifies the heating test for motor-starting relays. The coil is loaded according to the declared steady-state motor run current, while the contacts are not loaded.
That test choice matters because it checks the relay under coil stress without adding contact load that would change the result. For a test lab, the key point is to use the declared motor-running data from Table 1 and to place actuating members in the most unfavorable position.
Clause 19 applies Part 1 endurance requirements with some parts not applicable. This means endurance remains a core safety check, but the test set is trimmed to suit motor-starting relays rather than all control types.
Abnormal operation and fault response
Clause 26 keeps the general abnormal operation framework from Part 1, but it adds a specific burnout test note for electromechanical motor-start relays, relays, and contactors. For those devices, compliance is linked to successful completion of the endurance tests.
The blocked mechanical output test is not applicable. In practice, that narrows the fault scenarios that must be checked and avoids applying a test that does not fit this relay construction.
Functional safety and EMC
Annex H covers functional safety. For thermal cycling in H.19, the duration is changed from 14 days to 18 days, which extends the stress period used in the assessment.
Annex H also changes the EMC immunity approach for type 1 action motor-starting relays. Compliance for those relays is checked by the specified immunity tests, including the electrical fast transient/burst test, where the control is subjected to five tests.
The annex also says that failure to operate can be permitted in the immunity assessment, but the declared output must still be judged in the final application to avoid unsafe operation. That matters for integrators, because the relay may pass the standard yet still need application-level review.
Materials and insulation
The document keeps the Part 1 insulation and safety framework, but it adds a restriction on a specific insulation material group and PTI range. For manufacturers, that means material selection for insulating parts is part of compliance, not just a design preference.
What terms does oSIST prEN IEC 60730-2-10:2026 define?
oSIST prEN IEC 60730-2-10:2026 adds a few terms that matter for understanding how the relay is assessed.
- Motor-starting relay - An electrically operated control for an appliance motor circuit that connects the main winding and auxiliary starting winding so a single-phase motor can start.
- Type 1 action - A control action where the relay’s output behavior is treated as a basic safety-related action in the functional safety assessment.
- Class A control function - The note links electronic motor-starting relays to this class, which helps classify how the control behaves in safety evaluation.
- HBES/BACS - Home and Building Electronic Systems / Building Automation and Control Systems; the standard includes relays used in this environment.
- NTC thermistor - A thermistor with a negative temperature coefficient, used here as one of the control technologies covered.
- PTC thermistor - A thermistor with a positive temperature coefficient, also covered as a relay-control technology.
Who uses oSIST prEN IEC 60730-2-10:2026?
oSIST prEN IEC 60730-2-10:2026 is used by manufacturers of motor-starting relays, appliance makers, control engineers, test laboratories, and certification or conformity assessment bodies. It is also useful for quality managers and buyers who need to define what evidence a relay supplier must provide.
The standard is relevant across household appliances, building automation, smart-enabled controls, and equipment used in shops, offices, hospitals, farms, and commercial or industrial applications. In practice, it helps teams decide whether a relay design fits the intended motor circuit and what testing or documentation is needed before release.
What changed in oSIST prEN IEC 60730-2-10:2026 from the previous edition?
oSIST prEN IEC 60730-2-10:2026 cancels and replaces the 2.0 edition published in 2006. This edition is described as a technical revision.
The main stated change is adoption of IEC 60730-1 Ed. 6.0, including all of its significant changes. That means the Part 2-10 requirements are aligned with the updated Part 1 framework.
Which standards are used with oSIST prEN IEC 60730-2-10:2026?
| Standard | What it contributes |

| JIS C 9730-2-10 | National differences for Japan |
| CAN/CSA-E60730-2-10 | National differences for Canada |
What does the oSIST prEN IEC 60730-2-10:2026 document contain?
oSIST prEN IEC 60730-2-10:2026 contains clause-by-clause modifications to IEC 60730-1 rather than a full standalone test code. It includes the scope, a normative reference update, a new relay definition, technical-information requirements, and special rules for heating, endurance, and abnormal operation.
The document also includes Annex H for functional safety and regional annexes Q, R, S, and T for country-specific differences. Table 1 provides the technical information to declare and the way to provide it, and the figures of Part 1 remain applicable for the test arrangements.

58 FOREWORD
59 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
60 all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
61 co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
62 in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
63 Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC Publication(s)”). Their
64 preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
65 may participate in this preparatory work. International, governmental and non-governmental organizations liaising
66 with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
67 Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
68 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
69 consensus of opinion on the relevant subjects since each technical committee has representation from all
70 interested IEC National Committees.
71 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
72 Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
73 Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
74 misinterpretation by any end user.
75 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
76 transparently to the maximum extent possible in their national and regional publications. Any divergence between
77 any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
78 5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
79 assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
80 services carried out by independent certification bodies.
81 6) All users should ensure that they have the latest edition of this publication.
82 7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
83 members of its technical committees and IEC National Committees for any personal injury, property damage or
84 other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
85 expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
86 Publications.
87 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
88 indispensable for the correct application of this publication.
89 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent
90 rights. IEC shall not be held responsible for identifying any or all such patent rights.
91 IEC 60730-2-10 has been prepared by IEC technical committee 72: AUTOMATIC ELECTRICAL
92 CONTROLS. It is an International Standard.
93 This 3.0 edition cancels and replaces the 2.0 edition published in 2006. This edition constitutes
94 a technical revision.
95 This edition includes the following significant technical changes with respect to the previous
96 edition:
97 a) adoption to IEC 60730-1 Ed.6.0 with all of its significant changes.
IEC CDV 60730-2-10 © IEC 2026
98 The text of this International Standard is based on the following documents:
Draft Report on voting
XX/XX/FDIS XX/XX/RVD
100 Full information on the voting for its approval can be found in the report on voting indicated in
101 the above table.
102 The language used for the development of this International Standard is English.
103 This document was drafted in accordance with ISO/IEC Directives, Part 2, and developed in
104 accordance with ISO/IEC Directives, Part 1 and ISO/IEC Directives, IEC Supplement, available
105 at www.iec.ch/members_experts/refdocs. The main document types developed by IEC are
106 described in greater detail at www.iec.ch/publications.
107 A list of all parts of the IEC 60730 series, under the general title: AUTOMATIC ELECTRICAL
108 CONTROLS, can be found on the IEC website.
109 This part 2-10 is intended to be used in conjunction with IEC 60730-1. It was established on the
110 basis of the sixth edition of that standard (2022. Consideration may be given to future editions
111 of, or amendments to, IEC 60730-1.
112 This part 2-10 supplements or modifies the corresponding clauses in IEC 60730-1, so as to
113 convert that publication into the IEC standard: Particular requirements for motor-starting relays.
114 Where this part 2-10 states "addition", "modification" or "replacement", the relevant require-
115 ment, test specification or explanatory matter in part 1 should be adapted accordingly.
116 Where no change is necessary part 2-10 indicates that the relevant clause or subclause applies.
117 In the development of a fully international standard it has been necessary to take into
118 consideration the differing requirements resulting from practical experience in various parts of
119 the world and to recognize the variation in national electrical systems and wiring rules.
120 The reader's attention is drawn to the fact that Annexes Q, R, S and T lists all of the national
121 and regional differences on differing practices of a less permanent nature relating to the subject
122 of this document.
123 In this publication:
124 1) The following print types are used:
125 – requirements proper: in roman type;
126 – test specifications: in italic type;
127 – explanatory matter: in smaller roman type.
128 – Defined terms: bold type.
129 2) Subclauses, notes or items which are additional to those in Part 1 are numbered starting
130 from 101, additional annexes are lettered AA, BB, etc.
131 The committee has decided that the contents of this document will remain unchanged until the
132 stability date indicated on the IEC website under webstore.iec.ch in the data related to the
133 specific document. At this date, the document will be
134 • reconfirmed,
135 • withdrawn,
IEC CDV 60730-2-10 © IEC 2026
136 • replaced by a revised edition, or
137 • amended.
