28 Introduction
29 The purpose of this amendment is to identify and modify the requirements that would not fit the EMCD
30 requirements, so that the amendment could be harmonized under this Directive.
31 1 Modifications to Clause 1, “Scope”
32 Replace the full text below Figure 1 of Clause 1 with:
33 “Components of the above-named equipment and within the scope of this document are, for example:
34 — (auxiliary) stand-alone power supplies;
35 — peripherals such as digital and analogue I/O;
36 — remote-I/O;
37 — industrial network equipment, embedded or stand-alone (e.g. switches, routers, wireless base
38 station).
39 Control equipment and their associated peripherals are intended to be used in an industrial environment
40 and are provided as either OPEN or ENCLOSED EQUIPMENT.
41 NOTE Control equipment intended also for use in other environments or for other purposes (example: for use
42 in building installations to control light or other electrical installations, or for use on cars, trains or ships) can have
43 additional conformity requirements defined by the safety standard(s) for these applications. These requirements
44 can involve for example: insulation, spacings and power restrictions.
45 Equipment covered in this document is intended for use in overvoltage category II (IEC 60664-1) in low-
46 voltage installations, where the rated equipment supply voltage does not exceed AC 1 000 V r.m.s.
47 (50/60 Hz), or DC 1 000 V. If control equipment or their associated peripherals are applied in
48 overvoltage category III installations, then additional analysis will be required to determine the suitability
49 of the equipment for those applications.
50 The object of this document is to define clear, complete, and exhaustive technical requirements to
51 products falling in its scope.
52 Safety requirements for control equipment and their associated peripherals are specified in
53 IEC 61010-2-201.”
54 2 Modification to Clause 2, “Normative references”
55 Add the following references:
56 IEC 61000-3-2:2018, Electromagnetic compatibility (EMC) - Part 3-2: Limits - Limits for harmonic
57 current emissions (equipment input current ≤16 A per phase)
58 IEC 61000-3-3:2013, Electromagnetic compatibility (EMC) - Part 3-3: Limits - Limitation of voltage
59 changes, voltage fluctuations and flicker in public low-voltage supply systems, for equipment with rated
60 current ≤16 A per phase and not subject to conditional connection
61 3 Modifications to Clause 4, “Compliance and type tests”
62 Replace the first paragraph after the listing of options in 4.1 with:
63 NOTE All equipment is expected to comply with the requirements in Clause 7, Electromagnetic compatibility
64 (EMC) requirements.
65 Replace the last paragraph of 4.1 with:

As impacted by IEC 61000-3-2:2018/A1:2020 and IEC 61000-3-2:2018/A2:2024.
As impacted by IEC 61000-3-3:2018/A1:2017, IEC 61000-3-3:2018/A2:2021 and
IEC 61000-3-3:2018/A2:2021/COR1:2022.
66 “If different options are defined for normal service condition (e.g. OTH3, OTH4 …) or different realization
67 of functional requirements (e.g. Type 1 or Type 3 digital inputs) possible, the product documentation
68 shall clearly specify which option has been realized or the equipment has been evaluated against.”
69 Replace the second sentence of the second paragraph in 4.2.1 with:
70 “In accordance with the scope of this document, the conformance verification described above cannot
71 reflect every specific application of the intended automated control application.
72 However, the test configuration should be a typical, representative application.”
73 Add at the end of 4.2.1 the following sentence:
74 “A test plan shall be established prior to testing.”
75 Replace the last sentence of the first paragraph in 4.2.2 with:
76 “Thus, it is reasonable, and recommended, not to test every possible arrangement. Therefore, the
77 equipment assembly shall represent a typical installation as specified in the product documentation. All
78 equipment, racks, modules, boards, etc. significant to type test and belonging to the EUT shall be
79 documented. If relevant, the software version shall be documented.”
80 Delete the second paragraph in 4.2.2.
81 Replace the third paragraph in 4.2.2 with:
82 “Unless otherwise specified in this document, various number of EUTs may be elected to achieve the
83 objectives of a given type test.”
84 Replace the last sentence of the paragraph below Figure 2 in 4.2.2 with:
85 “To exercise different characteristics, capabilities, ports, etc. of each EUT, subsystems may be defined
86 and the different EUTs are tested in turn.”
87 Replace the example b) in 4.2.2 with the following:
88 “b) to check the electrical interference immunity of the EUT, between the following cases can be chosen,
89 as applicable:”
90 Replace the last sentence of case 2) in 4.2.2 with:
91 “For practical reasons, actual PADTs/TEs/RIOS to exercise the EUT ports may be elected.”
92 Replace the sentence after the list of examples and cases in 4.2.2 with:
93 “If there are too many families to be included into a single EUT, several EUTs shall be defined as
94 follows:”
95 Replace the first bullet point in 4.2.2 with:
96 “
97 — For the type testing of a family of very similar modules (family, i.e. modules that are technically
98 identical, e.g. use the same schematic and the same basic manufacturing process and differ mainly
99 by, for example, the number of inputs and outputs),only one module of the family can be arbitrarily
100 chosen as EUT. If the type test is depends on the differences between the modules, not only one
101 module of the family may be used.”
102 Replace the last sentence of the last but two paragraph in 4.2.2 with:
103 “This is only permissible if such EUTs and the associated test programs allow proper verification as if
104 these new units/modules had been tested within the originally tested EUTs.”
105 Replace the last but one paragraph in 4.2.2 with:
106 “Unless otherwise specified in this document, either each type test be conducted on a new EUT or
107 several type tests be performed successively on the same EUT.”
108 Replace the text of 4.2.3 with:
109 “Communication ports shall be connected as in normal use for ESD testing.
110 NOTE Pass-fail criteria are located in Table 1.”
111 Replace the second sentence in 4.2.5 with:
112 “If the product documentation indicates components that are normally serviced by the service
113 personnel, these components may be removed for the test.”
114 Replace the second and third paragraph in 4.2.7 with:
115 “For each test, the test plan shall contain the following information:
116 — the EUT configuration, its arrangement and its external connections;
117 — the test programs which shall be run during the test;
118 — the proper operation verification procedure, e.g. including the way to measure accuracy and
119 temporary deviations of analog I/Os.
120 The appropriate test programs and proper functioning verification procedures shall satisfy the
121 requirements given in 4.2.8.”
122 Add to the end of 4.2.2:
123 “A rationale for this election shall be documented in the test plan.
124 The EUT configuration and boundaries for EMC tests are defined in Clause 4.2.3 and the referenced
125 generic EMC standards. Requirements defined in 4.2.2 should not be considered for EMC testing.”
126 Replace the headline of 4.2.8 with:
127 “Requirements for test programs and proper functioning verification procedures (PFVPs)”
128 Replace the fourth paragraph in 4.2.8 with:
129 “
130 NOTE If the EUT provides many I/Os, the testing body can apply statistical methods to reduce the test effort.”
131 Replace the fifth paragraph in 4.2.8 with:
132 “Industrial control equipment often consists of systems with no fixed configuration. The kind, number,
133 and installation of different subassemblies within
