What is ISO 2909:2002 Petroleum products — Calculation of viscosity index from kinematic viscosity?
ISO 2909:2002 provides a method for calculating the viscosity index of petroleum products based on their kinematic viscosity at 40°C and 100°C.
The viscosity index is a measure of the change in viscosity of a fluid with temperature, and is an important parameter for assessing the performance of lubricating oils and other petroleum products. The standard specifies a formula for calculating the viscosity index from the kinematic viscosity values, and provides tables of reference values for use in the calculation.
It is intended for use by petroleum product manufacturers, users, and testing laboratories. As well as by regulatory agencies and other organizations involved in the evaluation and control of petroleum products.
Therefore, The standard provides a standardized method for determining the viscosity index of petroleum products, which is important for ensuring consistency and accuracy in product specifications, and quality control. Also, performance evaluation.
Requirements of ISO 2909:2002
ISO 2909:2002 specifies the requirements for the calculation of viscosity index of petroleum products from their kinematic viscosity at 40°C and 100°C.
The standard specifies the formula to be used for calculating the viscosity index and provides reference tables for the calculation. It also provides guidelines for selecting the appropriate reference tables based on the kinematic viscosity values.
In addition, ISO 2909 requires that the kinematic viscosity values be determined using a viscometer that conforms to ISO 3104:1994. The temperature of the petroleum product must be controlled and monitored during the viscosity measurement. And the results must be reported at 40°C and 100°C.
The standard specifies the reporting requirements for the viscosity index calculation. Including the kinematic viscosity values, the calculated viscosity index, and any other relevant information. Such as the reference tables used.
ISO 2909 also provides information on the limitations of the viscosity index calculation and the factors that may affect its accuracy. Such as the presence of certain additives or contaminants in the petroleum products
