Overview
EN 50289-3-9:2001 (CENELEC) specifies mechanical bending tests for communication cables used in analogue and digital systems. Part 3-9 defines test methods to assess how cables behave when bent, flexed, installed around rollers or mandrels, and when kinking or stiffness is a concern. It is intended to be read with EN 50289-3-1 (general mechanical test requirements) and refers to definitions in EN 50290-1-2.
Keywords: EN 50289-3-9, communication cables, bending tests, mechanical test methods, CENELEC, mandrel test, flexing, stiffness, kink test.
Key topics
- Scope: Bending around a mandrel; repeated bending; repeated flexing in service; flexing in service; bending around rollers/bows during installation; stiffness measurement; kink testing.
- Test procedures:
- Single bending - two procedures: (1) wrapping/unwraping in a close helix around a mandrel (one cycle = wrap + unwrap), (2) 180° U-bend and reverse U-bend cycles. Mandrel diameter, turns and cycle counts are specified per cable type.
- Repeated bending - oscillatory bending through ±90° under tensile load. Typical apparatus cycles ~1 cycle/2 s; sample lengths typically 1–5 m for physical checks; acceptance criteria based on transmission or physical damage.
- Flexing and flexing endurance - reciprocating carriage over pulleys with specified pulley diameters and weights; cycle defined by full traverse out-and-back.
- Cable bending under tension (dynamic test) and stiffness - several measurement methods provided (clauses for Method A/B/C).
- Kink test - procedures to check a cable’s susceptibility to forming kinks and resulting performance degradation.
- Acceptance criteria and reporting: Test reports must record procedure used, mandrel diameter or ratio, number of cycles, weights, bending radius, test temperature, allowable attenuation change, and pass/fail criteria. Typical failure modes: loss of electrical/optical continuity, increased attenuation, transmission degradation, or physical damage.
Applications
- Who uses it: cable manufacturers, independent test laboratories, quality assurance teams, procurement/specification engineers, installation contractors and certification bodies.
- Practical uses:
- Verifying mechanical robustness of coaxial, optical and symmetrical communication cables.
- Validating cable performance for repeated handling, installation around rollers/bends, and expected in-service flexing.
- Supporting product specifications, type approvals and supplier contracts by providing repeatable, auditable mechanical test results.
