Astm d 2939 03

Designation: D 2939 – 03

Standard Test Methods for

Emulsified Bitumens Used as Protective Coatings1

This standard is issued under the fixed designation D 2939; 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 (e) indicates an editorial change since the last revision or reapproval.

This standard has been approved for use by agencies of the Department of Defense.

Test Methods D 2939 are the methods recommended for use by Committee D08 in place of Methods D 1010 and D 1167.

1. Scope

1.1 These test methods cover procedures for sampling and

testing emulsified bitumens used in relatively thick films as

1.3 The values stated in SI units are to be regarded as

standard. The values in parentheses are for information only.

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 appro￾priate safety and health practices and determine the applica￾bility of regulatory limitations prior to use.

3. Significance and Use

3.1 These tests are useful in evaluating and characterizing

coal tar emulsion and other bituminous emulsions to establish

uniformity of shipments.

1 These test methods are under the jurisdiction of ASTM Committee D08 on

Roofing and Waterproofing and are the direct responsibility of Subcommittee

D08.09 on Bituminous Emulsions.

Current edition approved July 10, 2003. Published August 2003. Originally

approved in 1970. Last previous edition approved in 1998 as D 2939 – 98. 2 This test is intended to evaluate the relative resistance of coatings which might

be exposed to fuel spills.
