SIST EN 62005-4:2001

• Abstract:

  Describes product screening. A proper product screen is actually a process, not a test. As a process, it is maintained and constantly validated to ensure it achieves the purpose for which it was defined. This process is applied to a product in order to induce products with a known failure mechanism, to fail in a controlled situation before the product is deployed in the field. If this process is properly applied, then all infant mortality failures in the field, associated with the failure mechanism(s) for the screen, will be eliminated.

SIST EN 62005-4:2001 is a Slovenian standard from SIST for the reliability of fibre optic interconnecting devices and passive optical components. It specifies product screening as a controlled process for manufacturing and reliability teams who need known failure mechanisms to fail before products are deployed in the field.

What does SIST EN 62005-4:2001 specify?

SIST EN 62005-4:2001 specifies product screening and explains why screening is a process, not a test. The standard is organized into Scope, Screen versus testing, Proper design and implementation of a screening process, Types of screens, Ongoing validation of screen effectiveness, and Conclusion.

The scope also uses the classic “bathtub” failure-rate curve to explain where screening acts in the product life cycle. In practice, that helps readers see that the aim is to remove early-life failures without harming normal-use or wear-out performance.

What are the key requirements of SIST EN 62005-4:2001?

SIST EN 62005-4:2001 treats screening as an optional method for removing known early failures, not as a mandatory requirement. The standard says the choice to screen should be based on economics, customer expectations, and product use, and it should be considered against redesign or manufacturing improvement.

Identify the failure mechanism first

Clause 3 says the failure mechanism(s) must be isolated and understood before a screen is designed. In practice, a screen only works when it is matched to a specific mechanism, so the reader has to know what defect or weakness is being targeted.

Clause 3 also requires identification of acceleration stresses, safe stress limits, and the earliest suitable point in the process to apply the screen. That means the screen has to fit the product and the process, rather than being added late and possibly missing the defect.

Validate the screen on bad and good product

Clause 3 requires validation on a sample with known or deliberately induced defects, and then repeated runs on good product followed by life testing against unscreened product. In practice, this checks two things at once - that the screen finds the intended defects, and that it does not damage good units.

Clause 5 requires ongoing validation after implementation, including tracking product fallout and watching for changes in failure rates. If process or material improvements remove the failure mechanism, the screen can be removed; if the mechanism changes, the screen may need to be adjusted.

Apply screening as a production filter

Clause 2 says screening is applied to 100 % of manufactured pieces, while quality testing may be sampling-based or full inspection. The practical meaning is that screening is intended to separate out weak units, so some failures are expected and acceptable during the screen.

Use suitable screen types and durations

Clause 4 lists thermal, thermal cycling, humidity, mechanical shock, mechanical tension, and mechanical vibration as screen types. It also notes that if thermal cycling is used with mechanical perturbation, it is recommended after the mechanical tests, because damage may only appear at temperature extremes.

Clause 4 and the conclusion state that screens shall not have accelerated effects and shall not reduce lifetime or normal-use performance. Their duration must be long enough to expose defects but not so severe that good product is harmed.

What terms does SIST EN 62005-4:2001 define?

• Product screening - a controlled process applied to products to force units with a known failure mechanism to fail before field use.
• Screen - a specific set of conditions used to expose a known and understood failure mechanism.
• Failure mechanism - the specific cause or mode of failure that the screen is intended to reveal or remove.
• Infant mortality - the early-life failure period that screening aims to reduce in the field.
• Proof stress - a screening approach that uses stress to reveal weak products.
• Burn-in process - an electronics term for a screening process used to make early failures occur before shipment.
• Fallout - product that fails during screening and is removed from the population.

Who uses SIST EN 62005-4:2001?

SIST EN 62005-4:2001 is used by manufacturers of fibre optic interconnecting devices and passive optical components, and by the teams that support production quality. Reliability engineers, test engineers, quality managers, process engineers, and production managers use it when they need to design a screen, validate it, monitor fallout, or decide whether redesign is a better option.

It is also useful for buyers and technical specifiers who want to understand what a screening process means in practice. The document helps them ask the right questions about defect mechanisms, stress limits, and whether a supplier’s screen is still effective.

What changed in SIST EN 62005-4:2001 from the previous edition?

SIST EN 62005-4:2001 is identical to EN 62005-4:1999, and EN 62005-4:1999 reproduces IEC 62005-4:1999 without modification. The Slovenian edition therefore carries the same technical content as the European standard it adopts.

What does the SIST EN 62005-4:2001 document contain?

SIST EN 62005-4:2001 contains an explanatory figure of the classic bathtub failure-rate curve, plus text that distinguishes screening from testing and quality sampling. It gives a practical sequence for designing a screening process, including finding the failure mechanism, choosing stress conditions, setting safe limits, and validating the screen.

The document also lists example screen types such as thermal, thermal cycling, humidity, mechanical shock, mechanical tension, and mechanical vibration. It ends with guidance on ongoing validation and on keeping the screen aligned with the failure mechanism over time.

The object of the IEC is to promoteinternational co-operation on all questions concerning standardization in the electrical and electronic fields. Tothis end and in addition to other activities, the IEC publishes International Standards. Their preparation isentrusted to technical committees; any IEC National Committee interested in the subject dealt with mayparticipate in this preparatory work. International, governmental and non-governmental organizations liaisingwith the IEC also participate in this preparation. The IEC collaborates closely with the International Organizationfor Standardization (ISO) in accordance with conditions determined by agreement between the twoorganizations.2)The formal decisions or agreements of the IEC on technical matters express, as nearly as possible, aninternational consensus of opinion on the relevant subjects since each technical committee has representationfrom all interested National Committees.3)The documents produced have the form of recommendations for international use and are published in the formof standards, technical reports or guides and they are accepted by the National Committees in that sense.4)In order to promote international unification, IEC National Committees undertake to apply IEC InternationalStandards transparently to the maximum extent possible in their national and regional standards. Anydivergence between the IEC Standard and the corresponding national or regional standard shall be clearlyindicated in the latter.5)The IEC provides no marking procedure to indicate its approval and cannot be rendered responsible for anyequipment declared to be in conformity with one of its standards.6)
Attention is drawn to the possibility that some of the elements of this International Standard may be the subjectof patent rights.
