Overview
EN 60749-5:2017 (IEC 60749-5:2017) defines a steady-state temperature humidity bias life test used to evaluate the reliability of non-hermetic packaged solid‑state devices in humid environments. This European adoption of the IEC standard supersedes EN 60749-5:2003 and provides a technical revision that clarifies test applicability, corrects an equation, and adds guidance notes. The method is a destructive humidity bias test intended to accelerate moisture ingress and reveal failure mechanisms related to encapsulants, seals and conductive interfaces.
Key topics and requirements
- Scope: Reliability assessment of non‑hermetic semiconductor devices under sustained temperature, humidity and electrical bias.
- Typical test conditions: The standard specifies controlled temperature and relative humidity conditions (commonly cited as 85 °C / 85 % RH) applied continuously for extended durations. Test results under these steady‑state conditions take priority over HAST when both are performed.
- Equipment: A temperature–humidity chamber capable of continuous control and electrical biasing, with care to minimize temperature gradients and contamination.
- Contamination control: Selection of board, socket and wiring materials to avoid ionic contamination and corrosion; use of deionized water with a specified minimum resistivity for chamber processes.
- Biasing guidelines:
- Minimize device power dissipation
- Alternate pin bias where possible
- Distribute potential differences across chip metallization
- Maximize applied voltage within the device’s operating range
- Procedures: Defined mounting, ramp‑up/ramp‑down, read‑out and handling procedures; devices must be returned to stress promptly after interim measurements.
- Failure criteria and safety: The document specifies failure definitions and includes safety considerations for high‑temperature, high‑humidity testing.
Applications
- Accelerated humidity bias testing for qualification and screening of plastic‑encapsulated ICs, power devices, MEMS and other non‑hermetic semiconductor packages.
- Assessing long‑term moisture resistance, seal integrity, interfacial corrosion risk, and conductive path formation under bias.
- Supporting reliability dossiers for product development, supplier qualification, and failure analysis in electronics subjected to humid operating environments.
Who should use this standard
- Semiconductor test engineers and reliability labs
- Component and module manufacturers (non‑hermetic packages)
- Quality, qualification and failure‑analysis teams in automotive, industrial, consumer and avionics electronics
- Standards and compliance professionals specifying environmental stress tests
Related standards
- IEC/EN 60749-4 (HAST) - Damp heat, steady‑state, highly accelerated stress test. EN 60749-5 clarifies the relationship between steady‑state humidity bias tests and HAST.
Keywords: EN 60749-5:2017, IEC 60749-5, steady-state temperature humidity bias life test, semiconductor devices, non-hermetic packaged, humidity bias test, 85°C/85% RH, reliability testing.

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
