56 Lighting systems – Electro-mechanical interfaces – Part 1: Safety
59 FOREWORD
60 1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising all national
61 electrotechnical committees (IEC National Committees). The object of IEC is to promote international co -operation on all
62 questions concerning standardization in the electrical and electronic fields. To this end and in addition to other activities ,
63 IEC publishes International Standards, Technical Specifications, Technical Reports, Publicly Available Specifications (PAS)
64 and Guides (hereafter referred to as “IEC Publication(s)”). Their preparation is entrusted to technical committees; any IEC
65 National Committee interested in the subject dealt with may participate in this preparatory work. International, governmental
66 and non-governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely with
67 the International Organization for Standardization (ISO) in accordance with conditions determined by agreement between
68 the two organizations.
69 2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international consensus
70 of opinion on the relevant subjects since each technical committee has representation from all interested IEC National
71 Committees.
72 3) IEC Publications have the form of recommendations for international use and are accepted by IEC National Committees in
73 that sense. While all reasonable efforts are made to ensure that the technical content of IEC Publications is accurate, IEC
74 cannot be held responsible for the way in which they are used or for any misinterpretation by any end user.
75 4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications transparently to
76 the maximum extent possible in their national and regional publications. Any divergence between any IEC Publication and
77 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 assessment
79 services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any services carried out by
80 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 members of
83 its technical committees and IEC National Committees for any personal injury, property damage or other damage of any
84 nature whatsoever, whether direct or indirect, or for costs (including legal fees) and expenses arising out of the publicatio n,
85 use of, or reliance upon, this IEC Publication or any other IEC Publications.
86 8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is indispensable
87 for the correct application of this publication.
88 9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent rights.
89 IEC shall not be held responsible for identifying any or all such patent rights.
90 International Standard IEC 63494-1 has been prepared by IEC technical committee 34: Lighting.
91 The text of this standard is based on the following documents:
FDIS Report on voting
XX/XXX/FDIS XX/XXX/RVD

104 Lighting systems – Electro-mechanical interfaces – Part 1: Safety
105 1 Scope
106 This document specifies the safety requirements for electro-mechanical interfaces connecting lighting
107 system devices to luminaires. These interfaces are used to mechanically connect, electrically power,
108 and enable communication of lighting system devices on luminaires . Electro-mechanical interfaces up
109 to and including 1 000 V AC or 1 500 V DC are included. The document specifies safety related
110 mechanical, electrical, ambient conditions, and construction requirements for the interface
111 components including protective covers. Specific requirements for the devices that can utilize the
112 interface such as sensors, communication modules, cameras, etc. are out of scope for this document.
113 The document does not specify the following aspects:
114 • The lighting technology
115 • The illumination performance
116 • Data communication
117 • Functional safety
118 • The performance and interchangeability of devices on the interface
119 • Electromagnetic compatibility (EMC)
120 The document does not specify safety for the following:
121 • Product safety covered in existing standards (e.g. control gear, light sources, luminaires,
122 electrical connectors, PoE, USB)
123 • Device safety aspects for devices using the electro-mechanical interface
124 • Couplers for mains input power to the luminaire
126 The purpose of IEC 63494-1 is to provide a set of requirements and tests which are considered
127 generally applicable to electro-mechanical interfaces. Detailed requirements for particular electro-
128 mechanical interfaces are specified in the IEC 63494-2 series.
129 NOTE: If the electro-mechanical interface is not standardized in the IEC 63494-2 series then interchangeability aspects are
130 not covered.
131 NOTE: Although manual operation is anticipated at this time, future use of insertion and removal tools can be utilized and
132 covered by this safety standard.

192 Compliance is checked by inspection and by trying to remove the marking by rubbing lightly for 15 s
193 each time, with two pieces of cloth, one soaked with water and the other with aliphatic solvent hexane.
194 As an alternative, a reagent grade hexane with a minimum of 85 % as n-hexane may be used.
195 NOTE 2 n-hexane according to ACS (American Chemical Society) is identified as CAS# 110-54-3.
196 The marking shall be legible after the test. If the marking is on a separable label, the label shall remain
197 fixed to the product.

201 removal of the device-side interface into and from the luminaire-side interface without undue force or
202 torque by hand without the use of tools.
203 The following test shall be applied on a receptacle plus device or cap, if applicable: Prepare the
204 sample by completing 5 mating cycles of the device-side interface and luminaire-side interface, then

211 protective equipment during insertion or removal of the device.
212 Compliance shall be checked by inspection.
213 6.2 Physical safety in latching release mechanisms
