Work Item
ASTM WK88686
Revision of C1224-22 Standard Specification for Reflective Insulation for Building Applications
Rationale
ASTM C518 is a reliable and precise test method for determining material R-value with a reproducibility of about 3%. C1363 has a much larger measurement uncertainty than C518 that is magnified when a minor component of a test assembly is being evaluated. The use of C518 to determine framing R-value represents economy of resources in addition to improved accuracy.
