# ASTM D2939

Standard Test Methods for Emulsified Bitumens Used as Protective Coatings

[Back to all techniques](/analytical-techniques/)

## Significance and Use

These tests are useful in evaluating and characterizing coal tar emulsion and other bituminous emulsions to establish uniformity of shipments.

## Scope

1.1 These test methods cover procedures for sampling and testing emulsified bitumens used in relatively thick films as protective coatings for metals, built-up roofs, and bituminous pavements.

1.2 The test methods appear in the following order:
