Many cable manufacturers face rework and failed FAT inspection when their cables crack or break under cold climate. To solve this universal quality problem, SINUO launched the upgraded low temperature tensile test system fully compliant with IEC 60811-505 international standard. This integrated cryogenic testing equipment accurately detects low-temperature brittleness of cable insulation and sheath, helping export factories pass global customer acceptance smoothly.
Core Advantages of Our Low Temperature Tensile Test Equipment
- Fully follows all mandatory test parameters specified in IEC 60811-505: 30mm standard gauge length, fixed tensile speed of 50mm/min, minimum 2-hour constant temperature holding at -40℃.
- Built-in high-precision low-temperature chamber with ±2℃ temperature control accuracy, eliminating temperature fluctuation that distorts test data during stretching cycles.
- Custom cryogenic anti-slip fixtures for standard cable dumbbell samples, preventing sample slippage under cold conditions and ensuring accurate elongation rate measurement.
- PLC control system paired with a 7-inch color touch screen; all test data is automatically saved after power loss, and one-click PDF export generates official FAT test reports.
- Wide adjustable temperature range from -70℃ to ambient temperature, compatible with PVC, PE, XLPE, LSZH and all mainstream cable insulation and sheath materials.
Our test bench covers all low-temperature mechanical performance test requirements for power and communication cables, widely recognized by third-party testing labs and cable manufacturers worldwide:
| Standard Code | Full Standard Name | Main Test Application |
|---|---|---|
| IEC 60811-505 | Electric and optical fibre cables — Test methods for non-metallic materials — Elongation at low temperature for insulations and sheaths | Core cold tensile test for cable plastic layers |
| IEC 60811-501 | Tensile strength and elongation at ambient temperature for cable non-metallic materials | Room-temperature tensile contrast test |
| GB/T 2951.505 | Test methods for cables – Low temperature elongation of insulation and sheath (Identical to IEC 60811-505) | Domestic equivalent factory inspection standard |
Real Application Scenarios
Cable factories exporting to Europe, Southeast Asia and other global regions must conduct IEC 60811-505 low-temperature tensile tests before shipment. Unqualified cold elongation test records will lead to failed FAT inspection and third-party quality audits.
Our test system has been delivered to multiple cable manufacturers. QC teams rely on this machine to verify if cable insulation cracks or breaks under -40℃ harsh cold environments, generating standardized test reports for overseas buyers.

FAQ
What is the IEC 60811-505 low temperature tensile test used for?
IEC 60811-505 is the global unified international standard for cold elongation testing of cable insulation and sheath. It evaluates low-temperature material toughness and checks cable cracking risk in cold climates, a mandatory test for export power and communication cables.
What is the difference between IEC 60811-501 and IEC 60811-505?
IEC 60811-501 covers room-temperature tensile testing, while IEC 60811-505 focuses on tensile elongation under low temperatures. Our equipment supports both modes for comprehensive material comparison.
Can this machine generate formal FAT test documents?
Yes. The device records real-time tensile curves, temperature data and elongation values during testing. All data can be exported as official PDF reports directly for customer FAT acceptance procedures.
