Application
Cold Flexibility Testing (ISO 4674-2/ASTM D1790):
Samples are bent 10.000–50.000 times at -40°C to simulate polar or alpine conditions.
Results are graded based on crack appearance:
Pass: No visible cracks or coating separation.
Fail: Cracks exceeding 0.5 mm in width.
Standard Test
The tester adheres to international standards for material testing at low temperatures, including:
ISO 4674-2(Rubber- or plastics-coated fabrics – Determination of low-temperature bend test)
ASTM D1790(Standard test method for resistance of organic coatings to the effects of rapid deformation (impact))
GB/T 2423(China’s national standard for environmental testing – Cold tests)
EN 60068-2-1(Environmental testing – Cold tests for electronic components)
SAE J2339(Cold temperature impact resistance for automotive coatings)
These standards ensure consistent evaluation of material behavior under thermal and mechanical stress.
Feature
1. Material Cold Resistance Testing
This test simulates the dynamic bending process of materials such as rubber, plastics, leather, and synthetic fibers in low-temperature environments to detect their resistance to embrittlement and cracking. For example, by setting a -20°C environment, a shoe sole material can be subjected to 25.000 bending cycles to observe crack length and delamination, verifying whether it meets the standards for use in cold regions.
2. Product Reliability Verification
This involves evaluating the structural integrity of finished products such as shoes, automotive seals, and electronic device casings at low temperatures. For example, testing the deformation of a smart casing after 1000 bending cycles in a -10°C environment ensures the product can withstand extremely cold climates.
3. Research and Development and Quality Control
In the new material development stage, the bending performance of different formulations at low temperatures is compared to optimize material selection; in the production process, products are regularly sampled to ensure batch consistency and reduce after-sales complaints.
