- (a)Requirement. Before any manufacturer, importer, or private labeler distributes in commerce cellulose insulation which is subject to the standard, it shall ensure that the insulation is described in a written product specification.
- (b)Contents of specification. The product specification shall include the following information:
- (1)A description of the equipment used to manufacture the insulation, including the model number and names of the equipment manufacturers, and details of any modification made to any item of equipment.
- (2)A description of the cellulosic stock material used to manufacture the insulation, identifying the extent of impurities allowed.
- (3)The formulation of the fire-retardant chemicals added, including their chemical constituents and their form (for example, granulated, powdered, or liquid); the amount of fire-retardant chemicals present in the finished insulation, expressed as a percentage of the total weight of chemicals and cellulosic stock; the average weight of chemicals per bag; and the name and address of each chemical supplier. Where the chemical composition or formula of a commercially pre-mixed fire retardant is not known to the insulation manufacturer, the pre-mixed fire retardant may be described simply by the name and address of the supplier and its brand or trade name.
- (4)A description of the tests which were used to qualify the product as well as the dates of performance and results and actual values, where applicable, of the tests.
- (5)Any other information necessary to describe the insulation.
- (c)Distribution in commerce. After the qualification testing required by § 1209.34 has been completed with acceptable results and the product specification required by this § 1209.35 has been recorded, the cellulose insulation may be manufactured and distributed in commerce, subject to the provisions of § 1209.36.
- (d)New product. Whenever a manufacturer, private labeler, or importer makes any change to any item of equipment, cellulosic stock material, or formulation of a fire-retardant chemical, or any other factor which is likely to affect the ability of the cellulose insulation to meet the standard, that change will result in a new cellulose insulation product, requiring the preparation of a new product specification. The new product must be subjected to qualification tests and must yield passing or acceptable results.
