SIGNIFICANCE AND USE
These tests are useful in sampling and testing solvent bearing bituminous compounds to establish uniformity of shipments.
SCOPE
1.1 These test methods cover procedures for sampling and testing solvent bearing bituminous compounds for use in roofing and waterproofing.
1.2 The test methods appear in the following order:
Section Sampling4 Uniformity5 Weight per gallon6 Nonvolatile content7 Solubility8 Ash content9 Water content10 Consistency11 Behavior at 60°C [140°F]12 Pliability at –0°C [32°F]13 Aluminum content14 Reflectance of aluminum roof coatings15 Strength of laps of rolled roofing adhered with roof adhesive16 Adhesion to damp, wet, or underwater surfaces17 Mineral stabilizers and bitumen18 Mineral matter19 Volatile organic content20
1.3 The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

of the time required for 100 revolutions of the rotor produced by a specified load (compare with Test Method D562).
11.1.2 Apparatus:
11.1.2.1 Standard Stormer Viscometer.
11.1.2.2 Water Bath-Test Cup Assembly, without central baffle or thermometer holder.
11.1.2.3 Rotor, propeller-type (see Fig. 1).
11.1.2.4 Slotted Weights, and a suitable hanger.
11.1.2.5 Thermometer—ASTM stormer viscosity thermometer having a range from 20 to 70°C, and conforming to the
requirements for Thermometer 49C as prescribed in Specification E1.
11.1.2.6 Stop Watch.
11.1.3 Preparation of Apparatus:
11.1.3.1 Place the stormer viscometer on a table or shelf high enough to permit the weight to drop about 1 m (40 in.),[40 in.],
or sufficient distance to produce about 125 revolutions of the rotor. Insert the shaft of the propellar-type rotor in the chuck as far
as it will go and secure it with the set screw.
11.1.3.2 Raise the water bath-test cup assembly until the bottom of the test cup just touches the bottom of the rotor blade; then,
lower the assembly 6 mm ([ ⁄4 in.).in.]. Tighten the set screw on the position collar, if available, while the collar is in contact with
NOTE 1—All dimensions are subject to a tolerance of 60.1 mm ( [60.004 in.)]. Material: nickel-plated brass or stainless steel.

the bracket and the assembly, and use this setting to position the cup for all test runs. Using the set screws in the rim of the bath
holder, adjust the water bath-test cup assembly so that the cup and rotor are visually concentric.
11.1.3.3 For convenience in weight adjustment, attach a slotted metal can cover approximately 50 mm (2 in.)[2 in.] in diameter
to the hanger to support the slotted weights required.
11.1.4 Calibration:
11.1.4.1 Use a 94.85 % by weight aqueous glycerin solution as a calibration standard. Determine the initial concentration of
reagent grade glycerin by accurately measuring its specific gravity (seeAppendix X1), and then add additional water to make up
the desired total of 5.15 % by weight water.
11.1.4.2 Determine the weight on the viscometer cord (approximately 100 g) required to produce 100 revolutions of the rotor
in the glycerin calibration standard at 25 6 0.2°C in 18.0 6 0.2 s, this is the standardizing load. Check the calibration periodically,
particularly after prolonged use of the instrument, and recalibrate as necessary.
11.1.5 Procedure:
11.1.5.1 Remove the test cup and fill it with the sample to a level that will extend 6 mm ([ ⁄4 in.)in.] above the top of the rotor
blade. Agitate the sample in the cup thoroughly to remove any trapped air bubbles. Place the test cup in the water bath, and then
move the assembly up into test position against the preset collar.
11.1.5.2 Add 450 g to the standardizing load determined in 11.1.4.2. This will be the test load or driving weight.
11.1.5.3 Adjust the temperature of the sample and the entire test assembly to 25 6 0.2°C. To expedite reaching equilibrium,

11.1.5.4 Raise the driving weight on the cord so that it nearly touches the pulley. With stop watch in hand, release the brake
and observe the moving pointer. After 8 to 10 revolutions have been made, time the next 100 revolutions. Take the average of at
least three determinations and record as the Stormer consistency in s/100 revolutions. Record the driving weight.
11.1.5.5 Consistencies of up to approximately 100 s/100 revolutions shall be determined directly by timing 100 revolutions. For
higher consistencies, when timing 100 revolutions might unduly prolong the test, calculate the time required for
