| Summary | This standard specifies the general principle of rotation viscometer at a shear rate viscosity measurement requirements. Viscosity was measured in accordance with this standard is determined by the relationship between shear stress and shear rate constituted. According to this standard uses the results obtained by the measurement of different instruments are comparable, and both can be adjusted to test the instrument can also be controlled shear. |

Plastic liquid state or as emulsions or dispersions of polymer /
Resin using a rotary viscometer at a predetermined shear rate viscosity
Determination of Degree
1 Scope
This standard specifies the liquid emulsion state or suspended state polymers and resins, including polymer dispersion, using a standard geometry
Rotational viscometer at a shear rate viscosity determination specified general principles.
Viscosity determination in accordance with this standard is determined by the relationship between shear stress and shear rate of the composition. According to the different standard
The results obtained are comparable to the instrument of measurement, and adjusted either test equipment can also be controlled shear forces.

Principle 3
Viscometer measured viscosity liquid samples with the specified characteristics, which can measure the shear rate and shear stress application.
Viscosity η is defined by the following formula.
η = τ/γ
Where.
τ --- shear force;
--- Shear rate.
According to the International System of Units (SI), viscosity units of Pascal seconds (Pa · s)
1Pa · s = 1N · s/m2
Note 1. The symbol is consistent with GB 3102.3.
), The liquid is referred to is non-Newtonian. Liquid has no viscosity and shear rate
Kwan was called Newtonian.
