§1209.7. Test procedures for smoldering combustion. — Inbound Citations

(c) All cellulose insulation to which this interim standard applies, as described in § 1209.1, shall have no evidence of flaming combustion and shall also have weight loss of 15 percent or less of the initial weight, for each of the three specimens, when tested in accordance with the test procedures at § 1209.7.

The settled density of lose fill insulation must be determined before the corrosiveness test (§ 1209.5) and the smoldering combustion test (§ 1209.7) can be performed. This section describes the procedure for determining the settled density of loose fill insulation.
