ASTM D4283-98(2010)

Standard Test Method for Viscosity of Silicone Fluids

SIGNIFICANCE AND USE
3.1 The viscosity of silicone fluids is typically measured by kinematic viscosity. Test Method D445 describes the basics and background for this measurement. The purpose of this test method is to set forth specific conditions and recommend apparatus for measuring viscosity of silicone fluids.
SCOPE
1.1 This test method covers the measurement of the kinematic viscosity of silicone fluids for polish applications.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 This 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 consult and establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
