1.1This practice covers the calibration of master viscometers and viscosity oil standards, both of which may be used to calibrate routine viscometers as described in Test Method D445 and Specifications D446 over the temperature range from 15 to 100°C.
1.2The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.2.1The SI-based units for calibration constants and kinematic viscosities are mm²/s² and mm 2/s, respectively.
1.3This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. For specific warning statements, see Section 7.
