PULP, PAPER & PAPER BOARD TESTING
Paper and Paper Board Tests
- Analyze paper and paper board physical and optical properties such as texture, grammage, brightness, thickness and density.
- Examine the proximate chemical analysis for moisture, ash, extractives which include alcohol-cyclohexane, 1% NaOH, and hot/cold water and klason lignin.
- Determine strength properties such as resistance to bending, puncture, tearing, and crushing force of paper and board.
- Based on the following standards:
- ISO 2470 (Measurement of diffuse blue reflectance factor)
- ISO 2471 (Determination of opacity)
- ISO 1974 (Determination of tearing resistance)
- ISO 536 (Determination of grammage)
