Pulp laboratory sheets
Determination of physical properties
1 Scope
This standard specifies the method for determination of the physical properties of laboratory sheets.
This standard applies to laboratory sheet according to GB/T 24324 and GB/T 24326 prepared this standard with the corresponding standard method
use together.
In some cases, test methods specified in this standard differ from the corresponding standard method, which is due to the limited number of laboratory sheets.
NOTE. To determine the pulp diffuse blue reflectance factor (ISO brightness) of the laboratory sheets should be GB/T 8940.2 prepared.

Principle 3
Determination of pulp laboratory sheets for physical properties, such as laminated tightness, tensile index, tear index, burst index, air permeability, folding, bending
Qu stiffness and compression strength, is already prepared without beating or beating the pulp suspension into laboratory sheets, and the sheet is placed Standard Atmosphere
Equilibrium after treatment were measured.
