Full title and description

ASTM D2939-03 — Standard Test Methods for Emulsified Bitumens Used as Protective Coatings. This document specifies sampling and a suite of test procedures for evaluating emulsified bitumens (bituminous emulsions) applied as relatively thick protective coatings for metals, built-up roofs, and bituminous pavements.

Abstract

ASTM D2939-03 (2003) collected standardized test procedures to characterize emulsified bitumens used as protective coatings. Tests cover sampling, uniformity, physical properties (weight per gallon/density), residue and volatile content, ash and water content, flash point, drying time, resistance to heat, water and solvents, flexibility, application behavior, wet-film properties, impact resistance, and precision/bias information. The standard was withdrawn in 2012 in accordance with ASTM procedures for inactive documents.

Scope

The standard covers methods for sampling and laboratory testing of emulsified bitumens intended for use as protective coatings in relatively thick films. It addresses tests that apply generally to such coatings and additional procedures that are specific to coatings used on metal/built-up roofs or on bituminous pavements. Tests include physical and performance property determinations as well as tests to assess application behavior and resistance to environmental and chemical exposures.

Key topics and requirements

• Sampling procedures for emulsified bitumens and requirements for sample handling.
• Uniformity and resistance-to-freezing evaluations; storage/stability characteristics.
• Determination of weight per gallon (density), residue by evaporation, volatiles, ash content, and water content.
• Flash point and drying time test methods.
• Resistance-to-heat, resistance-to-water, flexibility, and application-behavior tests (brush, spray, wet flow).
• Solubility and solvent-resistance tests, wet-film continuity and resistance-to-volatilization for pavement applications.
• Impact-resistance testing, accelerated-weathering considerations, aggregate (sand) content for emulsions, and stated precision/bias information.

Typical use and users

Used by quality-control and R&D laboratories in manufacturers of emulsified bitumens, roofing and waterproofing product developers, pavement maintenance contractors, materials testing laboratories, specification writers, and regulatory or procurement authorities who require standardized test procedures for specification compliance and product comparison. Although D2939-03 itself has been withdrawn, its procedures historically guided testing and specification language in the roofing/waterproofing and paving sectors.

Related standards

Commonly referenced and related ASTM test methods and standards for bituminous materials and emulsions include (but are not limited to) ASTM D977 (Saybolt viscosity of emulsions), ASTM D6930 (settlement and storage stability), ASTM D6937 (density of emulsified asphalts), ASTM D95 (water content of petroleum products), ASTM D36 (softening point of bitumen), ASTM D5 (penetration of bituminous materials), ASTM D562 (viscosity by cup), and other D‑series methods for coating and emulsion characterization. Users should consult current ASTM listings to identify active, updated or replacement methods.

FAQ

Q: What is this standard?

A: ASTM D2939-03 is a collection of standardized test methods for sampling and testing emulsified bitumens used as protective coatings; it was issued in 2003.

Q: What does it cover?

A: It covers procedures for assessing uniformity, physical properties (density, residue, volatiles, ash, water), performance properties (drying time, resistance to heat/water/solvents, flexibility), application behavior, wet-film characteristics for pavement applications, and precision/bias for the listed tests.

Q: Who typically uses it?

A: Manufacturers, testing laboratories, specifiers, roofing and pavement contractors, and procurement/regulatory bodies that require consistent methods to evaluate emulsified bitumen coatings.

Q: Is it current or superseded?

A: ASTM D2939-03 was withdrawn in 2012. Withdrawal means the standard is no longer maintained in active ASTM publications; users should check ASTM International for currently active or replacement test methods before relying on D2939-03 for specification or compliance work.

Q: Is it part of a series?

A: It is part of the body of ASTM D‑series test methods covering asphalt, bituminous materials, and coatings; many related D‑standards exist for specific tests on emulsions and residues. Refer to the ASTM committee D08 (Roofing and Waterproofing) and related D‑series lists for the broader series.

Q: What are the key keywords?

A: Emulsified bitumen; bituminous emulsion; protective coatings; roofing; residue; volatiles; ash content; drying time; storage stability; ASTM D2939.
