ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications has approved a standard covering a test chamber used by transportation departments and similar agencies throughout the world to specify and test the dry speed of waterborne pavement marking paints at elevated relative humidity. 

WEST CONSHOHOCKEN, PA – ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications has approved a standard covering a test chamber used by transportation departments and similar agencies throughout the world to specify and test the dry speed of waterborne pavement marking paints at elevated relative humidity. 

The new standard, ASTM D 7539, Practice for Using a Test Chamber for Humidity Conditioning of Test Panels of Pavement Marking Paints, is under the jurisdiction of Subcommittee D01.44 on Traffic Coatings. The subcommittee is currently involved in revising ASTM D 711, Test Method for No-Pick-Up Time of Traffic Paint, and would like to hear from departments of transportation and other users of ASTM D 711.

ASTM International Committee D01 has also developed a new standard, ASTM D 7639, Test Method for Determination of Zirconium Treatment Weight or Thickness on Metal Substrates by X-Ray Fluorescence, to assist in the production of fit-for-purpose and cost-effective parts. 

According to Christelle Petiot, XRF Coatings Product Manager, Oxford Instruments Analytical, UK, “This standard will be used to measure the zirconium treatment weight or thickness applied to metal substrates, either along the process line, or in the quality control lab.”

The next step for Committee D01 and its Subcommittee D01.53 on Coil Coated Metal is to develop methods for other treatments such as chromium and titanium.
