1. Testing Method
Sample Preparation
Securely fix the shoelace to be tested onto the dedicated fixture of the testing machine. Ensure that the shoelace remains naturally straight without any twisting, knotting, or unnecessary stretching, so that the force is evenly applied during the test and the actual usage conditions can be accurately simulated.
Parameter Setting
According to the applicable testing standards, such as ISO, ASTM, GB, or other international and national standards, as well as specific customer requirements, accurately set key parameters on the equipment control panel, including friction frequency, reciprocating stroke, applied weight load, and preset number of friction cycles.
Start Testing
After confirming that all parameters are correctly set, start the testing machine. The shoelace will perform precise reciprocating friction movements under the preset constant conditions and continue operating until reaching the specified number of friction cycles or until obvious wear or breakage occurs.
Data Recording
The built-in sensors and data processing system of the testing machine automatically and continuously record key data throughout the testing process, including the accumulated number of friction cycles, total testing duration, exact breakage location of the shoelace, and possible changes in wear patterns. The system then automatically organizes the data and generates a detailed test report.
Result Analysis
Based on the complete data recorded in the test report, combined with relevant quality standards and customer specifications, the abrasion resistance grade and service life of the shoelace are scientifically evaluated. The results are used to accurately determine whether the shoelace meets the specified quality standards or purchasing requirements.
