Product Overview
Designed to assess the mechanical strength of sealed lighting chains, the ZLT-SDW Winding Flexible Pipe Flexing Test Device (by ZLTJC) fully complies with IEC60598-2-20 Fig 3 and IEC60598-2-20 clause 20.6.14. It simulates the stress of winding flexible pipes (used in lighting chains) around a fixed cylinder, measuring resistance to bending and structural damage. The test involves winding the pipe around a 250 mm wooden cylinder with a 60 N pull force, with cycles varying by IP rating: 10 cycles at 25°C ± 5°C (IP ≤20) and 10 additional cycles at -15°C ± 5°C (IP >20). Manufactured in China (shipped from Guangzhou Port), the ZLT-SDW has a lead time of 20 days, MOQ of 1 unit, and accepts T/T payments—making it essential for lighting manufacturers and test labs.

Product Features
Strict IEC60598-2-20 Compliance
Every component—from the 250 mm wooden cylinder to the 60 N pull force—aligns with IEC60598-2-20 standards. This ensures test results are valid for global certification, critical for lighting manufacturers targeting international markets.
Temperature-Specific Testing
The ZLT-SDW supports both standard (25°C ± 5°C) and low-temperature (-15°C ± 5°C) testing. Low-temperature cycles are essential for outdoor lighting chains, ensuring they do not become brittle or crack in cold environments.
Consistent Force Application
The fixed 60 N pull force (via a dedicated weight) guarantees uniform tension during winding, eliminating stress variations that could affect results. This consistency is key for batch-to-batch Quality Control.
Durable Mechanical Design
The robust support frame and smooth wooden cylinder (250 mm) minimize pipe abrasion. Its mechanical operation (no electrical parts for core functions) reduces maintenance needs and ensures long-term reliability.
Application
The ZLT-SDW Winding Flexible Pipe Flexing Test Device is indispensable for the lighting industry:
Lighting Chain Manufacturers: Testing flexible pipes to ensure they withstand winding without cracking or losing IP-rated water/dust resistance.
Outdoor Lighting Producers: Evaluating chains for garden or streetlights (IP >20) under low temperatures (-15°C ± 5°C) to ensure cold-weather durability.
QC Labs: Conducting batch tests to verify compliance with IEC60598-2-20, preventing defective products from entering the market.
Certification Bodies: Performing official tests for IEC60598-2-20 compliance, enabling manufacturers to sell products in IEC-regulated regions.
FAQ
Q: What test cycles are needed for different IP ratings?
A: For IP ≤20 chains: 10 cycles at 25°C ± 5°C. For IP >20 chains: 10 cycles at 25°C ± 5°C plus 10 cycles at -15°C ± 5°C to test low-temperature durability.
Q: Why is the cylinder made of wood?
A: Wood provides a smooth, low-abrasion surface with moderate friction—enough to simulate real-world winding without damaging the pipe or skewing results.
Q: Does the ZLT-SDW need electricity?
A: No, core testing is mechanical (winding via 60 N weight). For low-temperature testing, an external temperature chamber (not included) may be required.
Q: What is the lead time for the ZLT-SDW?
A: The standard lead time is 20 days. Custom cylinder diameters (for specialized testing) are available—contact the manufacturer for timelines.
