Work Item
ASTM WK97308
Revision of C578-23 Standard Specification for Rigid, Cellular Polystyrene Thermal Insulation
Rationale
C578 currently does not provide guidance on whether to apply rounding or use absolute values when reporting physical property data. This lack of clarity can lead to misinterpretation of compliance. Adopting E29's rounding method would establish a standardized approach for rounding and will ensure consistency across test labs, manufacturers, and certification bodies.
