Foreword
This revised standard adopts ISO 5269-2.2004 "Pulp physical testing - Part 2 Preparation of laboratory sheets. Quick Kaiser Law"
(In English).
This standard ISO 5269-2. Compared to 2004, the main differences are as follows.
--- Increasing the GB/T 24325 "Pulp Laboratory beating Wali (Valey) beater Law", with GB/T 24325 in place
ISO 5264-1. 1979, MOD;
--- With GB/T 10739 "Paper, paperboard and pulp sample processing and testing standard atmospheric conditions" instead of ISO 187.1990, EQV;
--- With QB/T 1462 "Pulp Laboratory wet solution from" instead of ISO 5263. 1979, EQV;
--- With QB/T 1463 "Pulp Laboratory beating PFI mill method" instead of ISO 5264-2. 1979, EQV;
--- The content of international standards in terms of the title after 4.2 4.1,4.1.1,4.1.2,4.1.3 and reserves converted note content.

Pulp was prepared for physical testing laboratory sheets
Fast Kaiser law
1 Scope
This standard specifies the use of rapid Kaiser sheet prepared by former laboratory sheets for physical testing in order to evaluate the relevant pulp
nature.
This standard applies to most types of pulp, but not for some long fiber pulp has, without the chopped cotton fiber, Asia
Hemp pulp and similar materials.
This standard does not apply to prepared according to GB/T 8940.2 Determination of laboratory sheets diffuse blue reflectance factor used.
NOTE. When used without chopped long fiber pulp, the evenness of the sheet may not be satisfactory.
