  All foam insulation materials using materials other than air or pentane as an expanding agent shall either separately condition samples at 73.4° ± 3.6°F and a relative humidity of 50 ± 5 percent, and at 140°F (60°C) dry heat and test at 30-, 60- and 90-day intervals or shall test samples certified by an approved testing laboratory to have been aged while exposed to free air in a well ventilated room for at least two years at 70° ± 10°F, provided, however, that until 2 [1] / 2 years after the adoption of these quality standards by the Commission, test samples may be aged for six months for certification of the material. Notwithstanding any other provision of this article, this thermal performance standard shall not take effect until 250 days after adoption. If the certification statement submitted pursuant to Section 1555 of these regulations does not include test results for thermal performance, the manufacturer shall submit a new certification statement which includes such test results prior to 250 days after adoption. If the latest certification statement is based on the six-month aging test, a new statement, based upon the two-year aging test or the accelerated aging test shall be submitted by 2 [1] / 2 years after the adoption date. 3. Dimensional stability. All foamed polyurethane and polyisocyanurate insulation materials which are factory formed shall be tested for dimensional stability in accordance with Procedures E and G of ASTM D2126-75 with the following exceptions: (a) sample size shall be 12 inches by 12 inches (305 mm by 305 mm) ± 1 inch (25 mm) and (b) samples shall be tested as manufactured with or without facers.

This subsection shall not apply to any product recognized by the International Conference of Building Officials, as of the date of adoption of these regulations, as complying with Sections 2602.1-2602.6 of the 1994 Uniform Building Code based solely upon diversified testing. The manufacturer of any product which is recognized by the International Conference of Building Officials, subsequent to the date of approval of these regulations, as complying with Sections 2602.1-2602.6 of the 1994 Uniform Building Code based solely upon diversified testing, may petition the Commission for an exemption of that product from the provisions of this subsection. 4. Dimensional stability. All foamed polystyrene insulation materials which are factory formed shall be tested for dimensional stability in accordance with Procedures E and G of ASTM D2126-75 with the following exceptions: (a) sample size shall be 12 inches by 12 inches (305 mm by 305 mm) ± 1 inch (25 mm), and (b) samples shall be tested as manufactured with or without facers.

  12-7-3 FIRE-RESISTIVE STANDARDS

  FIRE TESTING FURNACES

  STANDARD 12-7-3

  STATE FIRE MARSHAL

  SCOPE

  Sec. 12-7-300. This standard sets forth the general requirements for the design and control of fire testing furnaces intended for fire exposure testing and assignment of fire endurance ratings of building materials, assemblies of building materials, equipment and devices.

  FURNACE DESIGN AND DIMENSIONS

  Sec. 12-7-301. Furnaces shall consist of a furnace chamber and an insulated specimen frame. The furnace chamber walls and floor shall consist of insulating fire brick or equivalent heat-reflective materials. Furnace dimensions shall be not less than shown in the following:

  (a) Vertical large-scale wall furnace. The furnace exposure panel or door shall consist of an insulated steel restraining frame having an available opening for the test sample of not less than 200 square feet (18.6 m [2] ) in area with neither dimension less than 9 feet (2743 mm).

  (b) Vertical half-scale wall furnace. The furnace exposure panel or door shall consist of an insulated steel restraining frame having an available opening of not less than 50 square feet (4.6 m [2] ) for the test sample. Neither dimension of the furnace opening shall be less than 7 feet (2133 mm).

  (c) Horizontal large-scale floor furnace. The furnace exposure panel shall consist of an insulated steel restraining frame having an available opening of not less than 180 square feet (16.7 m [2] ) for the test sample. Neither dimension of the furnace opening shall be less than 12 feet (3657 mm).

  ** All foamed polystyrene insulation materials which are factory formed shall be tested for dimensional stability in accordance with Procedures E and G of ASTM D2126-75 with the following exceptions: (a) sample size shall be 12 inches by 12 inches (305 mm by 305 mm) ± 1 inch (25 mm), and (b) samples shall be tested as manufactured with or without facers.

  The average percent change in length or width shall not exceed ± 2 percent in 24 hours or ± 4 percent in 7 days. The average percent change in thickness shall not exceed ± 10 percent in 7 days. Samples shall be regarded as failing if: (1) delamination area of “faced” samples exceeds 25 percent or (2) warping or cupping exceeds [1] / 4 inch (6 mm) when checked by a straight edge across raised diagonal corners.

  (l) Polyurethane and polyisocyanurate in board form and field applied.

  1. Composition. The manufacture of the insulation shall be based mainly on the reaction of an organic polyisocyanate with a polyol resin.

  Board shall be of uniform texture, reasonably free from accumulation of unexpanded material and foreign inclusions, and reasonably free of broken edges and corners. It shall be reasonably free from holes, voids, depressions and objectionable odor. Laminated composite boards shall be included in this quality standard. The faces of laminated boards shall adhere firmly throughout to the foam, and shall show no excessive amounts of slits, voids or depressions. 2. Thermal performance. Determination of the thermal performance shall be in accordance with ANSI/ASTM C177-76, ANSI/ASTM C236-66 or ANSI/ASTM C518-76 at the manufacturer’s option. All foam insulation materials using materials other than air or pentane as an expanding agent shall either separately condition samples at 73.4° ± 3.6°F and a relative humidity of 50 ± 5 percent, and at 140°F (60°C) dry heat and test at 30-, 60- and 90-day intervals or shall test samples certified by an approved testing laboratory to have been aged while exposed to free air in a well ventilated room for at least two years at 70° ± 10°F, provided, however, that until 2 [1] / 2 years after the adoption of these quality standards by the Commission, test samples may be aged for six months for certification of the material. Notwithstanding any other provision of this article, this thermal performance standard shall not take effect until 250 days after adoption. If the certification statement submitted pursuant to Section 1555 of these regulations does not include test results for thermal performance, the manufacturer shall submit a new certification statement which includes such test results prior to 250 days after adoption. If the latest certification statement is based on the six-month aging test, a new statement, based upon the two-year aging test or the accelerated aging test shall be submitted by 2 [1] / 2 years after the adoption date. 3. Dimensional stability. All foamed polyurethane and polyisocyanurate insulation materials which are factory formed shall be tested for dimensional stability in accordance with Procedures E and G of ASTM D2126-75 with the following exceptions: (a) sample size shall be 12 inches by 12 inches (305 mm by 305 mm) ± 1 inch (25 mm) and (b) samples shall be tested as manufactured with or without facers.
