Summary:A method for assessing the cure status of a fibrous blanket manufactured with mineral fibers and binder is disclosed and comprises a first, qualitative assessment of cure followed by a second quantitative assessment that utilizes one of alternative procedures depending on the outcome of the first, qualitative assessment. For example, a first visual inspection may qualitatively reveal areas or undercure, upon which a second pH test of samples extracted from undercured areas may quantify the degree of undercure. Conversely, if the visual inspection reveals no undercured areas, a different sampling procedure examines different blanket areas for overcure status using a similar pH test.
