Call for Material Submissions for Round Robin Study to Determine Precision and Bias for Melamine Coatings Method

A task group of ASTM Subcommittee D01.21 on Chemical Analysis of Paints and Paint Materials is seeking interested participants as well as melamine coating suppliers to contribute materials for testing in a round robin. To participate, contact John Phillips at the address below.

ASTM Task Group D01.21.51A on Cure Formaldehyde in Coatings will use the study to determine precision and accuracy for their proposed Standard Test Method for Determination of Cure Formaldehyde in Melamine Coatings.

“The test method is designed to determine the amount of formaldehyde evolved from melamine coatings during the curing process,” said chemist John H. Phillips, an environmental control engineer with the Ford Motor Co., Dearborn, Mich. “Current test methods only measure free formaldehyde in coatings.”

Phillips said a total formaldehyde number can be obtained using the new test method and an existing ASTM test method for free formaldehyde, D 6191, Standard Test Method for Measurement of Evolved Formaldehyde from Water Reducible Air-Dry Coatings

The task group chairman, Phillips is drafting the test method with input from coatings suppliers, manufacturers, and users, particularly in the automotive industry, and academicians. The method is based in part on a report by USCAR [United States Council for Automotive Research], titled, “Effect of Test Conditions on the Generation of Cure Formaldehyde from Melamine Coatings.”

The standard is being balloted within ASTM under the guidelines of ASTM Committee D01 on Paint and Related Coatings, Materials, and Applications.

To participate in the round robin, contact John H. Phillips, Ford Motor Co., Dearborn, Mich. (phone: 313/ 845-1648). Committee D01 meets June 16-19 in Philadelphia, Pa. For meeting or membership details, contact Tim Brooke, manager, ASTM Technical Committees (phone: 610/832-9729). //
