Overview

EN IEC 63203-301-1:2024 (adopted by CLC) defines a standardized test method for electrochromic films used in wearable equipment. It establishes procedures, definitions and measurement conditions to assess visible-light colour changing performance and the key electrochromic properties: transmittance, response time (including darkening and bleaching), and long-term stability. The standard covers optical measurement from 380 nm to 750 nm and excludes electrochromic applications to displays.

Key topics and technical requirements

• Terms & definitions: Clear definitions for transmittance, response time, darkening time, bleaching time and long-term stability to ensure consistent test interpretation.
• Test environment: Environmental conditions follow IEC 60068-1 guidance - typical test conditions cited are 25 °C ± 2 °C, 50 % ± 2 % relative humidity and illumination under 300 lux.
• Equipment & instrumentation:
  • Voltage generator/DC power supply (capable of 0.1 V step control)
  • Potentiostat for controlled voltage application
  • Light source tunable across 380–750 nm
  • Spectrometer/photodetector and power meter to record transmitted radiance
  • Sample stage and computer-based data acquisition
• Measurement scope:
  • Transmittance measured as the ratio of transmitted to incident radiance (expressed as % transmittance)
  • Time-resolved measurement of bleaching and darkening transitions (response time)
  • Procedures for evaluating long-term stability under repeated or sustained actuation
• Procedure & reporting: Stepwise test procedure, data analysis methods and required content for the test report to support repeatability and traceability.

Practical applications and who uses this standard

• Wearable device manufacturers (smart glasses, adaptive eyewear frames, smart textiles with light-modulating panels) use the standard to validate material performance.
• Materials scientists and R&D labs develop electrochromic films and need reliable, comparable characterization methods.
• Independent test laboratories and certification bodies adopt the methodology for product verification and compliance.
• Component suppliers (transparent electrodes, electrolytes, films) use results to specify product data for integrators. Note: The standard is intended for wearable equipment applications and explicitly excludes display technologies.

Related standards

• IEC 63203-301-1:2024 (International edition)
• IEC 60068-1 - Environmental testing: general guidance (normative reference)
• EN IEC adoption by CENELEC/CLC and national standardization bodies (harmonized European version)

This guidance helps engineers, test labs and product managers apply EN IEC 63203-301-1:2024 to ensure consistent, repeatable evaluation of electrochromic films for wearable applications.

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international
co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and
in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,
Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their
preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with
may participate in this preparatory work. International, governmental and non-governmental organizations liaising
with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for
Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence between
any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.
9) IEC draws attention to the possibility that the implementation of this document may involve the use of (a)
patent(s). IEC takes no position concerning the evidence, validity or applicability of any claimed patent rights in
respect thereof. As of the date of publication of this document, IEC had not received notice of (a) patent(s), which
may be required to implement this document. However, implementers are cautioned that this may not represent
the latest information, which may be obtained from the patent database available at https://patents.iec.ch. IEC
shall not be held responsible for identifying any or all such patent rights.
