Overview

EN IEC 60068-3-6:2018 (CLC/CENELEC adoption of IEC 60068-3-6:2018) provides a uniform, reproducible method for confirmation of the performance of temperature/humidity (climatic) chambers. The standard describes procedures to verify chamber performance without specimens, intended for routine chamber performance monitoring and qualification. Edition 2 (2018) replaces the 2001 edition and includes clarified confirmation procedures. The publication is available as an RLV (Redline) version showing technical changes from the previous edition.

Key Topics

The standard covers practical measurement and reporting requirements for climatic test chambers. Major technical topics include:

• Measurement system and test area environment - requirements for the test environment and instrumentation used to confirm chamber performance.
• Temperature and humidity measurement systems - guidance on sensors, calibration traceability and appropriate instrumentation.
• Sensor placement - specified locations for temperature and humidity sensors (working space, minimal sensor configurations for different chamber volumes).
• Measurement methods - defined checks and analyses such as:
  • Achieved humidity and temperature setpoint verification
  • Stabilization behavior (time and profile to steady conditions)
  • Humidity fluctuation and short-term variation
  • Humidity gradient and spatial uniformity across the working space
  • Humidity variation in space and climatogram reporting
• Standard humidity sequence - recommended test sequences for consistent performance checks.
• Performance test reporting - required information to include in a formal chamber performance test report.

Applications

EN IEC 60068-3-6:2018 is applicable wherever reliable climatic conditioning is required:

• Routine performance monitoring and qualification of temperature/humidity chambers
• Initial commissioning and periodic re‑qualification of test equipment
• Supporting laboratory accreditation (e.g., ISO/IEC 17025) and internal quality systems
• Verification prior to carrying out IEC 60068-2 series climatic test procedures

Who should use this standard

• Environmental test lab managers and technicians
• Calibration and metrology laboratories
• Reliability and qualification engineers
• Manufacturers of climatic test chambers
• Quality assurance and compliance professionals

Benefits

• Improves test reproducibility and traceability
• Reduces uncertainty in environmental testing by standardizing chamber checks
• Helps demonstrate conformity to the IEC 60068-2 family of climatic test procedures

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) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of
patent rights. IEC shall not be held responsible for identifying any or all such patent rights.
International Standard IEC 60068-3-6 has been prepared by IEC technical committee 104:
Environmental conditions, classification and methods of test.
This second edition cancels and replaces the first edition published in 2001. This edition
constitutes a technical revision.
This edition includes the following significant technical changes with respect to the previous
edition:
a) Confirmation procedures are clarified.
