What is BS 188 - Viscosity of liquids about?
BS 188 is an International Standard that discusses the methods for determining the viscosity of liquids.
BS 188 describes the determination of the viscosity of liquids by the method using glass capillary viscometers and by the falling sphere method.
BS 188 applies only to liquids exhibiting Newtonian flow under the conditions of measurement. A test for Newtonian flow is also described in BS 188.
Who is BS 188 - Viscosity of liquids for?
BS 188 on viscosity of liquids is useful for:
- Manufacturers of viscometers
- Petroleum and petrochemical industries
- Testing authorities
- Quality assurance personnel
- Regulatory authorities
Why should you use BS 188 - Viscosity of liquids?
Viscosity is the property of a liquid to resist shear deformation increasingly with increasing rate of deformation. BS 188 discusses the principle along with various test methods and their procedures in a user-friendly manner.
BS 188 helps in the calculation and the expression of results for the viscosity of liquids that contributes to their physical characteristics. BS 188 also aids in the calibration of viscometers. BS 188 provides users with a test method for measuring the kinematic viscosity and for the calculation of dynamic viscosity from a knowledge of the kinematic viscosity and the density determined at the same temperature.
By adopting, BS 188 the user can understand more about methods for determining the viscosity of liquids. Viscosity is type of bulk density which is defined as liquid’s resistance to flow to gradual deformation by shear or and tensile stress.
