Test method being developed for bolted connections coating

14 May 2014

An ASTM subcommittee is developing a proposed standard: ASTM WK45390, Test Method for Slip Coefficient and Tension Creep Testing 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.
