ASTM D1665 – Standard Test Method for Engler Specific Viscosity of Tar Products (Withdrawn 2023)
Description:
Significance and Use
5.1 This test method is useful in characterizing the consistency of tar and tar distillates by measuring their flow properties. It is applicable to materials that are readily liquid at temperatures up to 100 °C.
Scope
1.1 This test method covers the determination of specific viscosity of tars and their fluid products. It does not determine absolute viscosity, but is an empirical flow test. Only by conforming strictly to requirements of the test method are reproducible results obtained.
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
