ASTM WK85033
Reinstatement of D402/D402M-14 Standard Test Method for Distillation of Cutback Asphalt (Withdrawn 2023)
Rationale
• Added Note 1 regarding D3666 as required by Committee D04 policy.
• Changed “milimetres” to “millimeters” throughout.
• The temperature of the sample needs to be brought to the elevation-corrected temperature of 360°C [680° F] with no tolerance given. The elevation corrections are given for every 1°C and every 1 or 2° F. It therefore can be assumed that the thermometer used must be capable of measuring temperature to the nearest ±0.5°C [1°F] is needed. The original thermometer specified, an ASTM 8C [8F] has subdivisions every 1 degree C [2 degrees F] and is readable at each half subdivision according to ASTM E1. An ASTM 8C [8F] thermometer has a maximum scale error of 1.5°C above 300°F [3°F above 570°F]. Since this is the thermometer traditionally used, the requirements of the digital alternative specified have been changed to match the specs on the 8C [8F] thermometer.
• Tables 1 and 2 have been combined. Titles have been added to the columns to provide the reader a better reference as to when to use each of the temperatures listed.
• Images have been updated to include both SI units and Inch-Pound Units
• Inch-pound units have been added in places where they are missing.
• The temperatures throughout the test in which the amount of distillate shall be recorded has been added to the test procedure for added clarity.
• Additional detail provided on how to determine the required sample mass in Section 8.
