ASTM D1901-10

This document is not an ASTM standard and is intended only to provide the user of an ASTM standard an indication of what changes have been made to the previous version. Because
it may not be technically possible to adequately depict all changes accurately, ASTM recommends that users consult prior editions as appropriate. In all cases only the current version
of the standard as published by ASTM is to be considered the official document.
Designation:D1901–00 (Reapproved2004) Designation:D1901–10
Standard Test Method for
Relative Evaporation Time of Halogenated
1
Organic Solvents and Their Admixtures
This standard is issued under the fixed designation D1901; the number immediately following the designation indicates the year of
original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A
superscript epsilon (´) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.
1. Scope
1.1 This test method covers the measurement of the relative evaporation time of halogenated organic solvents and their
admixtures. This test method is not applicable in the presence of excessive drafts or high-velocity air currents.
1.2
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.3 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.
2. Terminology
2.1 Definition:
2.1.1 admixture—a blend of a halogenated hydrocarbon with a nonhalogenated hydrocarbon (for example, mineral spirits).
3. Summary of Test Method
3.1 The evaporation rate is determined by measuring the time required for complete evaporation of a thin film of the solvent
from a sheet-metal panel in comparison with a reference standard solvent.
4. Significance and Use
4.1 This test method gives valid comparisons of the evaporation rates of the subject materials. These comparisons are required
for the determination of the suitability of a proposed material for specific cleaning applications.
5. Apparatus
2
5.1 Test Panel—A1 —A 1 by 100 by 150-mm (0.04 by 4 by 6-in.) panel of aluminum, AA Alloy 6061, Temper T4 or T6,
having a horizontal scribe mark across the width of the panel 25 mm (1 in.) from one 100-mm edge.
5.2 Support Base to hold the panel at 60 6 1° from the horizontal.
5.3 Stopwatch, or electric interval timer.
5.4 Graduate, 10-mL, with pouring lip.
6. Reagents
6.1 Perchloroethylene, initial boiling point 121°C, boiling range 2°C, purity 99 %.
6.2 p-Xylene,99%.
7. Procedure
7.1 Place a clean, water-break-free test panel on the support base at an angle of 60 6 1° from the horizontal, with the scribe
mark at the lower end of the panel (Note 1). Using the graduate, pour 10 mL of the material under test over the test panel, being
sure to get complete coverage of the entire exposed surface. As soon as the 10 mL of test material has been poured, observe the

upper edge of the panel for a break in the continuity of coverage. Start the timing at the first sign of a break in liquid film coverage
on the upper edge of the panel. Stop the timing when the last portion of film has receded below the scribe mark (Note 2). This
interval between the first sign of incomplete coverage and the receding of the last portion of film below the scribe mark is referred
to as the “dry time.”
NOTE 1—By placing a double thickness of paper toweling under the test panel and support base, solvent runoff from the panel is absorbed. The use
of fresh paper toweling after each individual test prevents saturation of the test area with solvent vapors and gives more reproducible results.
NOTE 2—Stray intermittent drafts must be avoided during the timing interval if reproducible results are to be obtained. Slight, steady air motion will
