Round Robin Cooperatives Sought to Update Precision and Bias for Insulation Test

An ASTM task group of Committee C16 on Thermal Insulation seeks testing laboratories to participate in a round robin. Participants should be users of ASTM C 351, Standard Test Method for Mean Specific Heat of Thermal Insulation. Multiple lab participation is desired to update the method’s precision and bias statement.

“C 351 is a test method written to test for specific heat of insulation materials,” said Tim Kunz, project manager for Testing Services, Holometrix Inc., and task group leader. “Specific heat values are used to calculate heat-up and cool-down times for various process systems and skin burn potential, among other things.

“The document (as with all ASTM standards) should be the result of contributions by as many participants as possible. Also, C16 now requires a fairly extensive precision and bias accuracy statement in all test methods that produce numerical results.”

Kunz said material for the round robin has not been chosen. “We are just starting to look at potential materials and it is likely that the task group would arrange to supply material.” The task group also seeks additional members; ASTM membership is not required to develop standards with the group.

To participate in the round robin and/or join the task group, contact Tim Kunz, project manager for Testing Services, Holometrix Inc., Bedford, Mass. (phone: 781/275-3300). Committee C16 meets April 14-17 in Pittsburgh, Pa. For meeting or membership details, contact Tim Brooke, ASTM Technical Committee manager (phone: 610/832-9729). //
