How to Verify Flexible Cable Durability Before Certification? A Smarter Approach with Flexing Testing

In today's cable industry, product reliability is no longer just a quality requirement—it has become a key factor for market access, customer trust, and certification approval.

Whether manufacturing power cords, industrial control cables, appliance cables, or highly flexible cables for demanding applications, one question remains critical:

Can the cable maintain electrical integrity and mechanical performance after thousands of bending cycles?

To answer this question, international standards such as IEC 60245 and IEC 60227 require rigorous flexing and bending tests to evaluate the mechanical endurance of finished flexible cables. Manufacturers and testing laboratories worldwide rely on dedicated cable flexing test equipment to ensure compliance before products enter the market.

During daily use, flexible cables are continuously subjected to bending, twisting, dragging, and repeated movement. Over time, these mechanical stresses may cause:

• Conductor breakage
• Insulation damage
• Short circuits between conductors
• Electrical discontinuity
• Reduced service life

Even a minor failure can lead to costly product recalls, certification delays, or customer complaints.

This is why international certification bodies such as TÜV, VDE, UL, and third-party laboratories require standardized cable flexing tests as part of their evaluation procedures.

To help manufacturers and laboratories streamline compliance testing, Sinuo has developed the IEC 60245-2 Flexible Cable Bending Test Machine, which integrates both two-pulley and three-pulley flexing test methods into a single system.

The equipment is designed according to:

• IEC 60245-1
• IEC 60245-2
• IEC 60227-1
• IEC 60227-2
• IEC 63294:2021

and supports testing for a wide range of finished flexible cables, including high-flex industrial cables, appliance power cords, TÜV-certified cables, VDE-certified cables, and UL-approved flexible cords.

Unlike conventional cable flexing systems, this machine combines mechanical testing with intelligent monitoring functions.

Key capabilities include:

• Two-pulley and three-pulley testing in one machine
• Adjustable load current up to 35A
• Single-phase and three-phase testing
• PLC + Industrial PC control system
• WiFi-enabled data management
• Automatic report generation
• Real-time fault detection
• Audible and visual alarm system

The system continuously monitors conductor continuity and detects open circuits, conductor-to-conductor short circuits, and cable-to-pulley short circuits throughout the entire testing process.

The tester accommodates:

• Cable cores: 2–18 cores
• Conductor size: 0.2–4 mm²
• Preset test cycles up to 999,999
• Multiple pulley diameters compliant with IEC requirements

This flexibility makes it ideal for:

• Cable manufacturers
• Quality control departments
• Third-party testing laboratories
• Certification organizations
• Research institutes
• Electrical appliance manufacturers
