Users should be aware that selling mercury and/or mercury containing products into your state or country may be prohibited by law.ġ.6 This standard does not purport to address all of the safety concerns, if any, associated with its use. See the applicable product Material Safety Data Sheet (MSDS) for details and EPA ’s website for additional information. Caution should be taken when handling mercury and mercury containing products. Mercury, or its vapor, may be hazardous to health and corrosive to materials. s.ġ.5 WARNING Mercury has been designated by many regulatory agencies as a hazardous material that can cause central nervous system, kidney and liver damage. For user reference, 1 mm 2/s = 10 -6 m 2/s = 1 cSt and 1 mPa The SI unit used in this test method for kinematic viscosity is mm 2/s, and the SI unit used in this test method for dynamic viscosity is mPa The precision has only been determined for those materials, kinematic viscosity ranges and temperatures as shown in the footnotes to the precision section.ġ.4 The values stated in SI units are to be regarded as standard. The procedure and precision values for residual fuel oils, which under some conditions exhibit non-Newtonian behavior, have been included.ġ.3 The range of kinematic viscosities covered by this test method is from 0.2 to 300 000 mm 2/s (see Table A1.1) at all temperatures (see 6.3 and 6.4). If, however, the viscosity varies significantly with the rate of shear, different results may be obtained from viscometers of different capillary diameters. Note 2-ISO 3104 corresponds to Test Method D445.ġ.2 The result obtained from this test method is dependent upon the behavior of the sample and is intended for application to liquids for which primarily the shear stress and shear rates are proportional (Newtonian flow behavior). Note 1-For the measurement of the kinematic viscosity and viscosity of bitumens, see also Test Methods D2170 and D2171. The dynamic viscosity, η, can be obtained by multiplying the kinematic viscosity, ν, by the density, ρ, of the liquid. 1.1 This test method specifies a procedure for the determination of the kinematic viscosity, ν, of liquid petroleum products, both transparent and opaque, by measuring the time for a volume of liquid to flow under gravity through a calibrated glass capillary viscometer.
