Reliability of fibre optic interconnecting devices and passive optical components - Part 4: Product screening
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.

Cette norme est applicable à un produit afin de conduire des produits ayant un mécanisme de défaillance connu, à avoir une défaillance dans le cadre d'une situation contrôlée, avant que le produit ne soit déployé sur le terrain. S'il est correctement appliqué, toutes les défaillances de moralité initiale sur le terrain, associées aux mécanismes de défaillance pour le tri, seront éliminées.

Overview
EN 62005-4:1999 (CLC/IEC) defines the principles and practical approach to product screening for fibre optic interconnecting devices and passive optical components. The standard treats screening as a controlled, maintained process rather than a single test. The primary objective is to induce and remove failures tied to known mechanisms so that infant‑mortality failures are eliminated before field deployment, improving overall product reliability.
Screening is illustrated using the classical bathtub curve of failure rates versus time: when properly applied, screening reduces early-life failures without degrading normal life or wear-out characteristics.
Key Topics
- Screen as a process, not a test: Screening requires continuous validation, monitoring and adjustment to remain effective and harmless to good units.
- Failure‑mechanism focus: A screen must be based on a clear understanding of the failure mechanism(s) it targets; effective screening cannot be designed without that identification.
- Design and implementation steps:
- Identify acceleration stresses relevant to the failure mechanism(s).
- Determine safe stress limits for materials and design.
- Select the earliest feasible point in manufacturing to apply the screen.
- Validate effectiveness and ensure no degradation of good parts.
- Monitor fallout and revalidate continuously.
- Types of screens (illustrative examples):
- Thermal exposure (prolonged temperature)
- Thermal cycling
- Humidity
- Mechanical shock, tension, and vibration
- Screen versus test: Unlike routine quality testing where failures are undesirable, screening accepts and expects some failures as a means to remove defective units. Screening is typically applied to 100% of production.
Applications
EN 62005-4:1999 is applicable to manufacturers, test engineers and quality teams responsible for:
- Implementing screening processes for fibre optic connectors, adaptors, couplers and other passive optical components.
- Designing proof tests or burn‑in operations that intentionally accelerate known failure modes.
- Reducing field infant‑mortality failures and improving customer confidence and system uptime.
Practical benefits include earlier detection and controlled removal of defective parts, reduced returns and warranty costs, and a clearer decision framework when choosing between screening and product redesign.
Related Standards
- EN/IEC reliability standards for fibre optic components and test methods (refer to your national or IEC catalogue for exact cross-references).
Notes:
- Screening is an optional alternative to redesign; the choice should be made based on economics, customer expectations and product use.
- Ongoing validation is essential: if process or materials change, screening parameters may need adjustment or may be removed when no longer required.
