Standard Practice for Representative Field Sampling of Traffic Paints

Importancia y uso:

5.1 For quality assessment and/or approval for use of traffic paint stored in the field, it is often necessary to obtain a representative sample for testing. Correct sampling of traffic paint is a skilled operation, and if not properly conducted with the right equipment and procedures, a sample may inadvertently fail one or more specification tests when evaluated by a testing laboratory. Among the test results that could be affected are solids content, resin content, TiO₂ content, heat-age stability, freeze-thaw stability, and dry time. Any of these could inadvertently result in non-approval or penalties.
