1  Scope
The objective of this Test Method is to specify procedures for the determination of kinematic viscosity of bituminous materials having kinematic viscosities in the range 6 mm 2 /s to 100 000 mm 2 /s (approximate dynamic viscosities 0.006 Pa.s to 100 Pa.s) using four different types of reverse flow capillary tube viscometers.
2  Application
ASTM D2170/D2170M-18 is the 2018 edition. Only the 2018 edition shall be used in accordance with this Test Method.

5  Operation
The requirements of ASTM D2170/D2170M-18 shall apply subject to the modifications set out in Appendix A for Australian conditions.
The following modifications are required for Australian conditions: Element Instruction/New text Cl 1.1 Delete clause and replace with the following: This Test Method covers procedures for the determination of the kinematic viscosity of cutback bitumens (referred to as “liquid asphalts”), flux oils (referred to as “road oils”) and the distillation residues of cutback bitumens at 60 °C. It also covers procedures for the characterization of kinematic viscosity of bitumens (referred to as “liquid asphalt binders”) at 135 °C. It is applicable in the kinematic viscosity range from 6 mm 2 /s to 100 000 mm 2 /s [cSt]. This kinematic viscosity range is approximately equal to a viscosity range of 0.006 Pa.s to 100 Pa.s. Cl 1.2 1 First sentence, delete “viscosity” and replace with “dynamic viscosity (referred to as “viscosity”)”. 2 Delete Note 1. 3 Delete Note 2. Cl 1.4 Delete clause and replace with the following: Values are stated in either SI units or imperial units in this Test Method. All measurements shall be made using SI units. Cl 2.1 Delete clause and replace with the following: The following documents are referred to in this Test Method: AS/NZS 2341.1, Method of testing bitumen and related roadmaking products, Part 1: Precision data — Definitions AS/NZS 2341.21, Method of testing bitumen and related roadmaking products, Method 21: Sample preparationASTM D2162, Standard Practice for Basic Calibration of Master Viscometers and Viscosity Oil Standards ASTM E1, Standard Specification for ASTM Liquid‐in‐Glass Thermometers Note—For referenced ASTM standards, visit the ASTM website, www .astm .org, or contact ASTM Customer Service at service@ astm .org.

Section 5 Delete section, including Clause 5.1 and Note 3. Cl 6.2 Delete clause and replace with the following: Thermometers — Selected in accordance with the following as appropriate: (a) For determinations at 60 °C — ASTM Kinematic Viscosity Thermometer 47C (IP 35C) as specified in ASTM E1.Cl 6.2 (cont’d) (b) For determinations at 135 °C — ASTM Kinematic Viscosity Thermometer 110C (IP 93C) as specified in ASTM E1. Note 3(A)—Other thermometric devices are permissible provided that their accuracy, precision and sensitivity are equal to or better than those of the thermometer prescribed. Cl 6.2.1 Delete clause, including Note 4. Cl 6.2.2 Delete clause, including Note 5. Cl 6.2.3 Delete clause, including Note 6. Cl 6.3 1 Delete last sentence and replace with the following: The efficiency of the stirring and the balance between heat losses and heat input shall be such that the temperature of the bath medium does not vary by more than ±0.1 °C over the length of the viscometer, or from viscometer to viscometer in the various bath positions. 2 Delete Note 7 text and replace with the following: Water is a suitable bath medium for determinations at 60 °C. Transparent paraffinic or silicone oils with a suitably high flashpoint (> 215 °C) have been found suitable for determinations at 135 °C. Cl 6.4 Delete second sentence. Cl 6.4.1 Delete clause. Cl 6.4.1.1 Delete clause. Cl 7.1 Delete clause and replace with the following: Bitumen and cutback bitumen samples shall be prepared in accordance with AS/NZS 2341.21.
