ASTM D1545 – Standard Test Method for Viscosity of Transparent Liquids by Bubble Time Method
Description:
Abstract
This test method covers the procedures for determining the viscosity of transparent liquids by bubble time method. The transparent liquids should be free from crystalline or gel particles. Test apparatus include a constant-temperature bath, standard viscosity tubes, a series of standard viscosity tubes as reference standards, timing device, tube racks, and viscosity tube corks.
Scope
1.1 This test method covers the determination of the viscosity in bubble seconds by timing. The bubble seconds are approximately equal to stokes for most liquids.
1.2 The test method is applicable to transparent liquids that are free from crystalline or gel particles.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
