Shiyun nylon cable ties always adhere to the internationally recognized UL standards and regularly conduct standardized and scientific inspections and tests on finished nylon cable ties to ensure product quality and reliability.
Temperature standards for nylon cable ties
According to the UL official standard, the operating temperature range of nylon cable ties is:
- Minimum temperature: -30℃
- Maximum temperature: 85℃
All standard cable ties are tested within this temperature range to ensure performance in extreme environments.
Low temperature test requirements under UL standards
There are two important low temperature testing requirements:
1. Low temperature installation test
- Sample Preparation:
- Randomly select 15-20 packaged nylon cable ties.
- Place the sample in an environment with a temperature of 18-28°C and a relative humidity of 45-55% for a period of time. Different thicknesses of cable ties require different resting times.
- Installation test:
- Mount the cable tie sample on a test mandrel with the maximum and minimum diameters claimed for the cable tie to ensure that the cable tie can be installed in the intended manner.
- After installation, check whether the cable ties can be tied properly and are not loose.
- High and low temperature test:
- Place the cable ties in a high and low temperature test device set at 85°C for 72 hours.
- Then place it in a constant temperature and humidity machine set at -30℃ for 2 hours.
- If the tested cable tie does not loosen or fall off and has no cracks on the surface under the long-term action of high and low temperatures, it means that it has passed the low-temperature resistance test and meets the UL low-temperature test standards.
2. Low temperature impact test
- Test Preparation:
- Place the cable ties in a machine set to -30°C for 2 hours.
- Impact Test:
- Transfer the installed cable tie test shaft to the low temperature impact tester for impact testing within 10 seconds.
- The inspection standard is also no loosening or falling off, and no cracks on the surface.
In conclusion
These two tests are the most basic test items given by the UL laboratory and are also important indicators for verifying the quality of nylon cable ties. Through these tests, Shiyun Nylon Cable Ties ensures the reliability and safety of its products in low-temperature environments, meets the requirements of UL standards, and provides users with high-quality product assurance.
