ASTM International is Developing Test Method for Bolted Connections Coatings
W. CONSHOHOCKEN, PA — An ASTM subcommittee is developing a proposed standard to test the slip coefficient properties of coatings used in slip-critical bolted connections. The test is based on an appendix in the “Specification for Structural Joints Using High-Strength Bolts,” published by the Research Council on Structural Connections. The proposed ASTM standard will expand on the Research Council standard by describing the preparation of test specimens in detail and by conducting an inter-laboratory study that will allow for the inclusion of precision and bias statement.
ASTM WK 45390, Test Method for Slip Coefficient and Tension Creep Testing of Coatings Used in Slip Critical Bolted Connections, is being developed by Subcommittee D01.46 on Industrial Protective Coatings, part of ASTM International Committee D01 on Paint and Related Coatings, Materials and Applications. The Research Council on Structural Connections is a non-profit, volunteer organization comprised of experts in the fields of structural steel connection design, fabrication, erection and bolting. Research projects funded by the RCSC serve to provide safety, reliability and standard practice for the steel construction industry.
