Test Procedures
1. Set appropriate test parameters
Based on specific requirements, determine appropriate test parameters such as temperature, humidity, stress, or strain to ensure the accuracy and repeatability of the test results.
2. Select suitable test specimens
Select suitable specimen shapes and sizes based on the material characteristics, and ensure that the specimen preparation process meets standard requirements.
3. Data analysis and interpretation
Perform systematic analysis and interpretation of the test results, including indicators such as cracking time, cracking distance, and crack propagation rate, to provide a scientific basis for subsequent applications and decision-making.
4. Safe operation
During operation, pay attention to safety precautions, ensuring that the test platform is stable and avoiding excessive stress or strain that could cause damage to equipment or personnel.
