Revision of D445-21e1 Standard Test Method for Kinematic Viscosity of Transparent and Opaque Liquids (and Calculation of Dynamic Viscosity)


At the ASTM D02.07.A Section meeting, held on June 28, 2022 in Seattle WA, a proposal drafted by Pat Maggi (Section Chair) and Alex Lau (Chair CS94 – Statistics) was presented for revision to clarify the proper way to handle multiple determinations in automated viscometers. This involves adding a new numbered Section in both the transparent and opaque liquid sections. This added verbiage addresses the way automated viscometers handle determinability which differs from their manual counterparts and also aligns with the way the statistical analysis was conducted for the precision estimates on these types of instruments.
