The UP-4002 Automatic Leather Bending Tester determines the resistance of flexible materials to cracking or other types of failure at flexing creases. This method is applicable to all flexible materials, particularly leathers, coated fabrics, and textiles used in footwear uppers.
Compliance Standards
SATRA TM 55; IULTCS/IUP 20-1; ISO5402-1; ISO 17694; EN 13512; EN344-1 section 5.13.1.3 and annex C; EN ISO 20344 section 6.6.2.8; GB/T20991 section 6.6.2.8; AS/NZS 2210.2 section 6.6.2.8; GE-24; JIS-K6545
Testing Methodology
The test specimen is folded in half with one end secured in a clamp. The specimen is then turned inside out and the free end secured in a second clamp at 90 degrees to the first. The first clamp repeatedly oscillates through a fixed angle at a defined rate, causing the specimen to flex. At set intervals, the number of flexing cycles is recorded and specimen damage is visually assessed. Tests can be conducted with wet or dry specimens at ambient conditions.
