Acceptance Criteria for Polypropylene Roof Underlayments AC 207 & Acceptance Criteria for Roof Underlayments for use in severe climate areas AC48. Tested in accordance with ICC-ES AC 48 and AC 207 criteria to meet UBC, IBC and IRC requirements for Roofing Underlayments.

*ASTM E 96 - Method B (wet cup method) typically gives a more realistic result for permeance than does the Method A (dry cut/desiccant) method.
