• 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)
- ISO 534 (Determination of thickness, density and specific volume)
- ISO 1924 (Determination of tensile properties)
- ISO 2758 (Paper -- Determination of bursting strength)
- ISO 2759 (Board -- Determination of bursting strength)
- ISO 3035 (Determination of flat crush resistance)
- ISO 7263 (Determination of the flat crush resistance after laboratory fluting)
- ISO 13821 (Determination of edgewise crush resistance)
- ISO 5626 (Paper -- Determination of folding endurance)
- ISO 5627 (Determination of smoothness)
- TAPPI 462 (Castor Oil Penetration Test for Paper)
- TAPPI 437 om-08 (Dirt in Paper and Paperboard Test Method)
- ISO 535 (Determination of water absorptiveness)
- ISO 2493 (Determination of resistance to bending)
- ISO 3037 (Determination of edgewise crush resistance (unwaxed edge method)
- ISO 2471 (Determination of opacity)
- ISO 1974 (Determination of tearing resistance)
- ISO 536 (Determination of grammage)
