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.
