GB/T 22235-2008Determination for viscosity of liquids (English PDF)

GB/T 22235-2008 is the English-translated version of 液体粘度的测定.

GB/T 22235-2008 — This standard specifies the method for determination of the viscosity of the liquid. 5 ways to include the principles of this standard are applicable to Newtonian fluid, which only spin Turn viscometer method can be used for non-Newtonian fluids.

Specific features of these methods is shown in Table 1.

Table 1 test methods Dynamic viscosity / (MPa · s) Kinematic viscosity /(Mm2 · s) Measuring range /(MPa · s or mm2 · s) Standard Source Temperature requirements /Capillary viscometer sqrt 0.5 ~ 105 ISO 3104 ± 0.1 Flow Cup sqrt 8 ~ 700 ISO 3105 ± 0.5 Viscometer sqrt 10 ~ 109 ISO 3218.2 ± 0.2 Falling ball viscometer sqrt 0.5 ~ 105 DIN53015 ± 0.1 Pull the ball viscometer sqrt 0.5 ~ 107 DIN52007.2 ± 0.1 this standard applies to the determination of the viscosity of the liquid.
