Glue Bond Separation of Weather-Resistant Grades:
The facings and corrugated medium of fiberboard shall remain securely and continuously adhered to their contacting
surfaces when tested as specified in paragraph 7.4 of the ASTM D4727/D4727M standards. Edge separation shall

Samples are pulled from each production run of weather resistant fiberboard and tested for compliance with the required
specifications. Test results are recorded for each grade and are available to our customers upon request.
