§12-02 Tests of Fire-Resistive, Flameproofed Materials Used in Places of Public Assembly and Special Occupancy Structures
Title 2 ‒ Board of Standards and Appeals > 12 Fireproofing > §12-02 Tests of Fire-Resistive, Flameproofed Materials Used in Places of Public Assembly and Special Occupancy Structures
(a) Scope. These requirements apply to flameproofed combustible materials used for decorative or other purposes within special occupancy structures as defined in §27-4266 and other places of public assembly as provided in §27-4266.
(b) General requirements. It shall be unlawful for any person to use any decorations, drape, curtain or scenery used for artistic enhancement, which is made of combustible material, unless painted or saturated with a non-combustible material or liquid or otherwise rendered safe against fire to the satisfaction of the Fire Commissioner and in accordance with the requirements of these rules, in any building of a public character, including a hotel, theatre, restaurant, public hall, department store, and a building used or intended to be used for purposes of public assembly, amusement or instruction, and a building where large numbers of persons congregate (See §27-4266) except as exempted in §12-02(g). After flameproofing, such processing as ironing, sewing and normal handling shall have no detrimental effects on the treatment of the material.
(c) Approval of materials and methods used in flameproofing textiles, etc. No materials or methods for flameproofing combustible materials for use under these rules shall be used unless approved by the Board.
(d) Flameproofing properties. The flameproofed material, when subjected to the test described in §12-02(e), shall meet the following requirements as to fire-retardant prop- erties.
(1) Flashing. No flashing shall occur at any time on the length of the test specimen. A flashing due to fuzz or bad edges may be disregarded.
(2) Duration of flame. The average continuation of flaming shall not exceed 3 seconds.
(3) Duration of glow. The average continuation of glow at the edge of the charred area shall not exceed an additional twenty seconds after the cessation of flaming. Glow confined to the charred area may be disregarded.
(e) Tests. Tests for each specific installation of originally treated combustible material, or any re-tests thereof, shall be made by the Fire Commissioner, or in a laboratory approved by him, in accordance with the requirements of these rules.
(1) Sampling for test specimens. Samples of each variety of material and for every kind of treatment shall be subject to separate tests. Samples shall be of sufficient size to furnish test specimens provided for in §12-02(e)(2). At least three samples shall be furnished for every 500 square feet or fraction thereof.
(2) Test specimens. Specimens for test shall be 2 in. wide and 12 1/2 in. long and shall be numbered on one end. Test specimens shall be carefully cut from at least three different places in the material to provide a minimum of three test specimens from each material for testing.
(3) Conditioning of test specimens. The test samples or test specimens shall be dried for 24 hours in a room of average temperature of 70°F., with an average humidity of 40%.
(4) Test for permanence of chemicals. Test specimens shall be suspended by folding and pinning one-half inch of the numbered end over a horizontal 8-gauge wire, placed two inches above the center of a 7-inch opening in a 3 ft. wind tunnel arranged to deliver a wind velocity to the air, at the tunnel end, of 700 lineal feet, plus or minus 50 ft. per minute, as measured by a suitable anemometer on a line with the wire. In this position the test specimens shall be whipped for five minutes. Immediately upon conclusion of this test, the specimens shall be placed in a closed dry container until required for the flame test.
(5) Apparatus for flame test. The apparatus shall consist of a ring stand 20 inches high with an adjustable clamp housed in a metal shield 12 inches square and 20 inches high, open in front and at both ends and a Bunsen or Tirrill gas burner which shall have a tube of 3/8-inch inside diameter.
(6) Flame test. A whipped test specimen shall be taken from the closed container required in §12-02(e)(4) and suspended vertically with one-half inch of the numbered end in a clip held in a clamp on the ring stand so that the test specimen shall hang vertically within and near the center of the metal shield required in §12-02(e)(5). The lower end of the test specimen shall be three-quarters of an inch above the top of the gas burner on which the air supply is shut off completely and adjusted to give a luminous flame 1 1/2 inches long. The flame shall be applied for 12 seconds, then withdrawn. The result of the test for duration of flame and duration of glow of the three test specimens shall each be averaged and recorded. Flashing, if any, shall be noted.
(f) Approval and certification. The approval of materials that have been flameproofed, as provided in §12-02(a) and tested as required in §12-02(e) with flameproofing properties as given in §12-02(d), shall be limited to one year. An affidavit by the person, firm or corporation flameproofing the combustible materials shall be filed with the Fire Commissioner stating that the flameproofing compound and method complies with the approval of the Board, with calendar number thereof, and including the date of treatment and warranted period of effectiveness of the flameproofing. The Fire Commissioner may require check tests at any time. Upon the termination of the approval, as provided for in §12-02(f), a retest of the flameproofed combustible materials shall conform to the following:
Flameproofed materials shall withstand a test of at least 400°F., as measured by a pyrometer, or other acceptable method, for approximately one minute's duration by means of an open flame. Under such test, the flameproofed material shall not flash or support combustion and shall not glow outside of the char if a char is set up by the open flame. Material found not to conform to these requirements shall be removed and replaced with materials conforming to the requirements of §12-02(d).
(g) Exemption. These rules shall not be construed to apply to merchandise for sale or displayed for sale, to guest rooms in hotels, to offices, to works of art in museums, nor to churches or places of religious worship.
