Overview

EN IEC 62947:2022/prA1:2026 Amendment 1 sets out updated methods for measuring the performance of electrically operated spray seats intended for household and similar applications. Developed by the CLC and IEC SC 59L (Small Household Appliances), this amendment introduces refinements and new generalized test approaches for spray seats, especially in areas concerning spray and heated seat performance. The updates are designed to enhance the reliability, repeatability, and relevance of laboratory testing, driving consistency in the development and assessment of electric toilet seats with integrated spray functions.

Key Topics

• General Test Conditions
  The amendment aligns test conditions with national requirements for protection against pollution by backflow, referencing existing country-specific regulations and standards.

• Spray Performance Measurement

  • Improved accuracy in measuring spray emission timing and spray temperature stability under varying water pressures.
  • Adjusted measurement references and schema for clarity and repeatability.
  • Updated specifications for measurement apparatus dimensions for standardized test setups.

• Heated Seat Performance

  • Introduction of an alternative thermography-based method for evaluating seat heating, utilizing calibrated thermal viewers for comprehensive thermal profiling.
  • Procedures for both long-term (stabilized heating) and short-term (transient response) temperature measurements.
  • Guidelines for defining valid measurement and exclusion areas, consideration of emissivity, and mitigating measurement errors from environmental factors.

• Water & Energy Consumption
  Minor clarifications in referencing test procedures aim to enhance the precision of consumption measurement for both water and energy during spray seat testing.

• Test Media Preparation
  Clarified and updated guidance on preparing water and other test media for consistent and representative spray performance measurements, including revised terms and figure references.

Applications

EN IEC 62947:2022/prA1:2026 provides practical value for manufacturers, testing laboratories, and certification bodies working with electrically operated spray seats and similar bathroom appliances. Typical applications include:

• Product Development and Design:
  By following these updated general test methods, producers can accurately assess the performance of new designs, ensuring compliance with European and international safety and quality standards.
• Laboratory Testing:
  Accredited laboratories leverage these standardized procedures to produce reliable, comparable results across products and markets.
• Certification and Conformity Assessment:
  Third-party certifiers utilize these methods as benchmarks for verifying product claims and regulatory compliance.
• Quality Assurance:
  Manufacturers integrate standardized test methods into routine QA processes to ensure consistent product performance and consumer protection.

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