4、 measuring the timefor a volume of liquid to flow under gravity through acalibrated glass capillary viscometer.The dynamic viscosity,can be obtained by multiplying the kinematic viscosity,bythe density,of the liquid.NOTE1For the measurement of the kinematic viscosity and viscosityof bitumens,see als
5、o Test Methods D2170 and D2171.NOTE2ISO 3104 corresponds to Test Method D445 03.1.2 The result obtained from this test method is dependentupon the behavior of the sample and is intended for applicationto liquids for which primarily the shear stress and shear ratesare proportional(Newtonian flow beha
6、vior).If,however,theviscosity varies significantly with the rate of shear,differentresults may be obtained from viscometers of different capillarydiameters.The procedure and precision values for residual fueloils,which under some conditions exhibit non-Newtonianbehavior,have been included.1.3 The ra
7、nge of kinematic viscosities covered by this testmethod is from 0.2 mm2/s to 300 000 mm2/s(see Table A1.1)at all temperatures(see 6.3 and 6.4).The precision has onlybeen determined for those materials,kinematic viscosityranges and temperatures as shown in the footnotes to theprecision section.1.4 Th
8、e values stated in SI units are to be regarded asstandard.The SI unit used in this test method for kinematicviscosity is mm2/s,and the SI unit used in this test method fordynamic viscosity is mPas.For user reference,1 mm2/s=10-6m2/s=1 cSt and 1 mPas=1 cP=0.001 Pas.1.5 WARNINGMercury has been designa
9、ted by manyregulatory agencies as a hazardous substance that can causeserious medical issues.Mercury,or its vapor,has been dem-onstrated to be hazardous to health and corrosive to materials.Use Caution when handling mercury and mercury-containingproducts.See the applicable product Safety Data Sheet(
10、SDS)for additional information.The potential exists that sellingmercury or mercury-containing products,or both,is prohibitedby local or national law.Users must determine legality of salesin their location.1.6 This standard does not purport to address all of thesafety concerns,if any,associated with
