As unfortunate as this accident was, we are still not convinced that a breakaway buckle is desirable. Randy will read the letter in Friday's meeting. Randy believes this type of use weakens the overall meaning of ASTM standards, and will draft a ballot item forbidding partial use of standards. Projections on the outer surface of helmets were discussed, with no clear conclusion about how to measure them. A better approach might be to quantify the effect on the sliding resistance or the helmet's tendency to snag in a fall.
Confusion continues on the required mass of the spherical impactor.
Serge Dextraze will chair a task group including Frank Lin, Larry Maddux and Dan Pomerening to consider calibration. Lori Kuller of 3M asked if there is any interest in reflectivity of helmets. Dean Fisher recalled a CPSC test in which reflectivity made essentially no difference in visibility, while Randy remembered the same test and thought reflectivity made a significant difference in his observations. No one was particularly interested. The effect of anvil finish on test results was brought up.
