Introduction
1. Background and purpose of the standard
GB/T32368-2015 "Test method for high temperature and high humidity aging of adhesive tapes" is a national standard of the People's Republic of China, which aims to regulate the aging performance test of adhesive tapes in high temperature and high humidity environments. The standard was proposed by the China Petroleum and Chemical Industry Federation and is managed by the National Adhesive Standardization Technical Committee.
2. Comparison of standard frameworks
| Standard dimensions | GB/T32368-2015 | GB / T2792 | GB / T4850 |
|---|---|---|---|
| Scope of application | Determination of high temperature and high humidity aging performance of adhesive tape | Peel strength test | Slow speed unwinding strength test |
| Test conditions | (40±2)℃ or (65±2)℃, relative humidity (85±2)% | - | - |
| Testing indicators | Appearance change, stickiness, peel strength | Peel strength | Low speed unwinding strength |
3. Implementation suggestions and practical applications
Implementation suggestions:
- Strictly control the test environment to ensure that the temperature and humidity meet the standard requirements.
- Choose appropriate instruments and equipment, such as dryer, air circulation oven or constant temperature and humidity chamber.
- Prepare the specimen according to the standard requirements to ensure that the specimen width and length meet the requirements.
- Regularly calibrate the instruments and equipment to ensure the accuracy of the test results.
