ISO 4113:2010
Scope
This International Standard specifies the requirements for calibration fluids, i.e. a basic fluid and a closer value
(CV) fluid, intended for testing and calibrating diesel fuel injection equipment in production, in service, and in
laboratories. The CV calibration fluid requires a closer tolerance range for kinematic viscosity and density, and
can be specified to enhance the accuracy of the calibration setting.
This International Standard also allows the specification of an anti-wear (AW) requirement in order to aid the
running-in of diesel fuel injection equipment.
