Principle 3
The sample was placed in 80 ℃ and 65% relative humidity, a predetermined time after treatment, some of the performance before and after sample processing, such as tensile strength,
Folding strength and other properties, optical properties and changes in brightness, pH and other chemical properties, it can be approximated to infer a few years later of paper and paperboard
Natural variations or similar paper stability strength order.
4 instruments and equipment
4.1 aging box. can be controlled at a temperature of (80 ± 0.5) ℃ and relative humidity (65 ± 2)% condition. It can be used to automatically adjust the temperature and humidity
Climate chamber, can also be used as described in Appendix C processing temperature and humidity instrument.
NOTE. In order to ensure that the fluctuation range of less than 2% relative humidity, should strictly control the temperature error is less than 0.5 ℃.
4.2 Performance Analyzer. relative performance analyzer shall comply with the relevant national standards or other appropriate testing methods.
4.3 dryer. or other pre-processors, the relative humidity should be controlled at 10% to 35%.
5 sampling and processing
Samples taken and processed according to the provisions of GB/T 450 and GB/T 10739 of.
Preparation 6 samples
6.1 Sample preparation 5 parts by corresponding national standards for measuring its performance.
6.2 Avoid bare hand and take samples, specimens should avoid glare and excessive exposure to the chemical laboratory air.
