IEC 61300-2-4-2020 PDF

Full title and description

St IEC 61300-2-4-2020 — Fibre optic interconnecting devices and passive components — Basic test and measurement procedures — Part 2-4: Tests — Fibre or cable retention. This publication is the consolidated/updated edition that incorporates Amendment 1 published in January 2020; it defines tensile-retention test methods to verify that fibres, cords or cables remain securely retained or attached in devices and enclosures under loads representative of normal service and handling.

Abstract

This part of IEC 61300 specifies test procedures and severities for assessing fibre, cord and cable retention in connectors, adaptors, splices, enclosures and other fibre‑optic interconnection hardware. The standard gives the test setup, sample preparation, applied tensile loads and pass/fail criteria intended to ensure safe mechanical retention during installation and operation.

Scope

This part of the IEC 61300 series establishes test methods to determine whether the retention or attachment of a fibre, cord or cable in a fibre‑optic device, connector or enclosure will withstand the tensile loads likely to be encountered during normal service and handling. It covers specimen preparation, test apparatus, applied forces, durations and the interpretation of results but does not address optical performance testing beyond mechanical retention effects.

Key topics and requirements

• Defined tensile‑load test procedures for fibre, cord and cable retention.
• Specified test setups, mounting and sample preparation to ensure reproducibility.
• Severity levels and test durations representative of typical installation and handling stresses.
• Pass/fail criteria focused on mechanical retention and absence of unacceptable displacement or damage.
• Guidance for test reporting and result interpretation to support conformity assessment.

Typical use and users

Used by manufacturers of fibre‑optic connectors, adaptors, patch panels, splice enclosures and cable assemblies to qualify designs and production batches; by test laboratories performing type and routine tests; and by procurement and quality engineers who require objective mechanical retention evidence for components used in telecommunications, datacom and industrial fibre‑optic installations.

Related standards

Part of the IEC 61300 series (basic test and measurement procedures) — other parts address optical insertion loss, environmental tests, vibration, impact, damp heat and cleanliness. National and regional adoptions (EN IEC/BS/ISO equivalents) and JIS adoptions exist; Amendment 1 (2020) is published to clarify procedures and severities.

Q: What does it cover?

A: It covers tensile retention test setups, sample preparation, applied loads and durations, and pass/fail criteria to determine whether retention/attachment is adequate under expected handling and service loads.

Q: Who typically uses it?

A: Manufacturers, test houses, quality and procurement engineers in telecom, datacom and industrial sectors who need to qualify or verify mechanical retention of fibre‑optic components and assemblies.
