IEC 61300-2-52-2013 PDF

Full title and description

Fibre optic interconnecting devices and passive components — Basic test and measurement procedures — Part 2-52: Tests — Bending test for cords. This International Standard specifies a mandrel-bending test procedure to determine the suitability of single‑fibre cords and multiple‑fibre circular cords to withstand bending likely to occur during normal use; it is not applicable to ribbon cables.

Abstract

IEC 61300-2-52:2013 defines the apparatus, test procedure, severity levels and information to be specified for a mandrel bending test applied to fibre‑optic cords. The aim is to assess whether a cord construction endures repeated bending around mandrels of specified diameters without unacceptable degradation of optical or mechanical performance. The test applies to single‑fibre cables and multiple‑fibre circular cables and excludes ribbon constructions.

Scope

This part of IEC 61300 describes a procedure to determine the suitability of a cord to withstand bending around a mandrel of the sort to be applied during normal use. The test procedure, apparatus, test specimen preparation, severity levels and required information to be specified are given. It is applicable to single fibre cables and multiple‑fibre circular cables and is explicitly not applicable to ribbon cables. Users should apply this test in combination with the general guidance in IEC 61300-1 and with any product specification that defines performance limits and required severity.

Key topics and requirements

• Definition of test specimen and conditions for mandrel bending (mandrel diameters, number of cycles, bending radius relative to cord diameter).
• Required apparatus and test setup (mandrel type, fixtures, environmental conditions and instrumentation).
• Procedure steps including conditioning, application of bend cycles, and post‑test examinations/measurements.
• Severity levels and criteria to be specified by the ordering document or product specification.
• Performance assessment: optical attenuation/attenuation variation, mechanical damage and pass/fail criteria as defined by the associated specification.

Typical use and users

Manufacturers of fibre‑optic cords and jumpers, test laboratories, product qualification and quality assurance teams, and procurement/specification engineers use this test method to verify cord robustness against bending stresses encountered in typical installation and service conditions. The test is used to support product datasheets, type approval and compliance with customer or sector specifications.

Related standards

IEC 61300-1 (General and guidance) should be used in conjunction with this part. Other parts of the IEC 61300 series (Parts 2 and 3 series) define additional mechanical, environmental and optical tests and examinations that are commonly applied together in product specifications. EN 61300-2-52:2013 is the European adoption of IEC 61300-2-52:2013.

FAQ

Q: What is this standard?

A: IEC 61300-2-52:2013 is an International Standard that specifies a mandrel bending test for fibre‑optic cords (single fibre and circular multi‑fibre cords) to assess their ability to withstand bending loads representative of normal use.

Q: What does it cover?

A: It covers apparatus, specimen preparation, test procedure, severity levels, and what information needs to be specified when ordering the test. It addresses optical and mechanical performance after bending and excludes ribbon cables.

Q: Who typically uses it?

A: Cable and cord manufacturers, independent test laboratories, QA/qualification engineers, and specification writers who need to verify bending durability of fibre‑optic cords.

Q: Is it current or superseded?

A: The IEC base publication IEC 61300-2-52:2013 is shown as withdrawn by the IEC (withdrawal date listed as 31 December 2018). National or regional adoptions (EN, national bodies) may have differing withdrawal/withdrawn‑from‑sale dates; users should check national catalogues or the IEC catalogue for the current normative status in their country before relying on it for formal compliance.

Q: Is it part of a series?

A: Yes — it is Part 2‑52 of the IEC 61300 series (Basic test and measurement procedures) and is intended to be used together with IEC 61300-1 (general guidance) and other IEC 61300 parts that specify additional tests and examinations.

Q: What are the key keywords?

A: Fibre optic, cord, bending test, mandrel, attenuation, IEC 61300, test procedure, cable durability.
