Full title and description

Reliability stress screening - Part 1: Repairable assemblies manufactured in lots. This international standard gives methods to apply and optimise reliability stress screening (RSS) processes for lots of repairable hardware assemblies when early-life reliability is unacceptably low and other approaches (for example reliability growth programmes or quality-control techniques) are not applicable.

Abstract

IEC 61163-1:2006 describes principles, planning steps, pilot-production and mature-production screening procedures, data collection and evaluation techniques, and practical considerations for implementing RSS on repairable assemblies produced in lots. The standard emphasises that RSS is intended to detect and remove early-life defects from production lots and is not a substitute for design improvements or ongoing quality-control programmes.

General information

• Number of pages: IEC PDF: 161 pages (IEC webstore metadata). Note: EN/national adoptions (EN/BS documents) of EN IEC 61163-1 often have shorter page counts (~80–90 pages) due to formatting or adoption documents.

Scope

The standard applies to lots of repairable assemblies for which early-life failures are a problem and where other mitigations are impractical. It gives guidance on when RSS is appropriate, how to plan and implement screening at pilot and mature production stages, how to collect and evaluate screening data (including estimation of the failure‑free period T[M]), and how to use screening results to optimise the RSS process. It is procedural and intended for application across production phases rather than providing specific test plans for particular technologies.

Key topics and requirements

• Principles of reliability stress screening (purpose, limits, and relationship to reliability growth and quality control).
• Definitions and failure categorisation (classification of early failures and how they affect screening strategy).
• Planning RSS programmes: selection of stresses, stress conditioning, sample sizes, and acceptance/termination criteria.
• Pilot-production screening: data collection, evaluation methods and re-evaluation of screening parameters.
• Mature-production screening: ongoing monitoring, statistical evaluation, and optimisation of screening to balance yield, cost and reliability benefit.
• Data analysis guidance (time graphs, estimation of failure‑free period, use of statistical methods to inform RSS decisions).
• Procedures for repair/rework, retest and record keeping for screened assemblies.
• Guidance on limitations: RSS does not improve intrinsic design reliability and should not replace corrective design actions where feasible.

Typical use and users

Manufacturers of electronic and electro‑mechanical assemblies, reliability and test engineers, production/quality managers, defence and aerospace contractors, subcontractors providing RSS services, and procurement/specification engineers use IEC 61163-1 to plan, specify and implement RSS programmes for repairable assemblies produced in lots. The standard is used both to design in‑house screening and to define requirements for outsourced screening services.

Related standards

IEC 61163-1 is part of the IEC 61163 series on reliability stress screening. Closely related documents include IEC 61163-2 (Reliability stress screening — Part 2: Components, latest edition 2020) and former guidance IEC 60300-3-7 (replaced by parts of the IEC 61163 series). Other complementary dependability and test standards (for example various IEC 60300 series parts and component/test standards) are commonly referenced when designing RSS programmes.

FAQ

Q: What is this standard?

A: IEC 61163-1:2006 is an international standard that provides procedural guidance for reliability stress screening of repairable assemblies manufactured in lots. It defines planning, implementation and evaluation practices for RSS programmes.

Q: What does it cover?

A: It covers the principles and practical steps for applying RSS to production lots of repairable assemblies, including planning, pilot-production screening, mature-production screening, data collection and evaluation, stress conditioning, and guidance on repair/retest and record keeping. It emphasises that RSS removes early-life defects but does not substitute for design fixes.

Q: Who typically uses it?

A: Reliability engineers, production and quality managers, test laboratories, OEMs, defence/aerospace contractors and subcontractors that supply RSS services or need to specify RSS in contracts or procurement.

Q: Is it current or superseded?

A: IEC 61163-1:2006 is the 2006 edition of Part 1 (which superseded the 1995 edition). Users should check national and regional adoptions (EN/BS/other) for status in their jurisdiction and consider related updated parts (for example IEC 61163-2 was revised in 2020 for components).

Q: Is it part of a series?

A: Yes — it is Part 1 of the IEC 61163 series on reliability stress screening; Part 2 addresses components (IEC 61163-2) and other IEC dependability documents and application guides are complementary.

Q: What are the key keywords?

A: Reliability stress screening (RSS), repairable assemblies, early failures, pilot production, mature production, screening optimisation, Weibull analysis, dependability, TC 56.
