(a) Test specimen.

The test specimens shall be rectangles of cloth 23/4 inches by 12 inches (±1/16 inch) with the long dimensions parallel to either the warp or filling directions of the material.

(b) Test apparatus required.

(1) Cabinet. A cabinet and accessories, fabricated in accordance with the requirements specified in Figures A, B and C. Galvanized sheet metal or other suitable metal shall be used. The entire inside back wall of the cabinet shall be painted black to facilitate the viewing of the test specimen and pilot flame.

(2) Burner. The burner used in the test shall conform to the following:

(i) The burner shall be equipped with a variable orifice to adjust the flame height, a barrel having a 3/8 inch inside diameter, and a pilot light.

(ii) The burner may be constructed by combining a 3/8 inch inside diameter barrel 3 ±1/4 inches long from a fixed orifice burner with a base from a variable orifice burner.

(iii) The pilot light tube shall have a diameter of approximately 1/16 inch and shall be spaced 1/8 inch away from the burner edge with a pilot flame 1/8 inch long.

(iv) The necessary gas connections and the applicable plumbing shall be as specified in Figure D except that a solenoid valve may be used in lieu of the stopcock valve to which the burner is attached. The stopcock valve or solenoid valve, whichever is used, shall be capable of being fully opened or fully closed in 0.1 second.

(v) On the side of the barrel of the burner, opposite the pilot light there shall be a metal rod of approximately 1/8 inch diameter spaced 1/2 inch from the barrel and extending above the burner. The rod shall have two 5/16 inch prongs marking the distances of 3/4 inch and 11/2 inches above the top of the burner.

(vi) The burner shall be fixed in a position so that the center of the barrel of the burner is directly below the center of the specimen.

(3) Control valve system. A control valve system with a delivery rate designed to furnish gas to the burner under a pressure of 21/2±1/4 lbs. per square inch at the burner inlet. The manufacturer's recommended delivery rate for the valve system shall include the required pressure.

(4) Gas. The gas used shall be Matheson Manufactured Gas Type B or the equivalent.

(5) Metal hooks and weights. Metal hooks and weights to produce a series of total loads to determine damaged length. The metal hooks shall consist of 19 gauge steel wire or equivalent and shall be made from 3 inch lengths of the wire and bent 1/2 inch from one end to a 45 degree hook. One end of the hook shall be fastened around the neck of the weight to be used.

(6) Stop watch. Stop watch or other device to measure the burning time to 0.2 second.

(7) Scale. Scale, graduated in 0.1 inch to measure the damaged length.

The following procedures shall be followed when testing wall and top material:

(1) The specimen in its holder shall be suspended vertically in the cabinet in such a manner that the entire length of the specimen is exposed and the lower end is 3/4 inch above the top of the gas burner. The apparatus shall be set up in a draft free area.

(2) Prior to inserting the specimen, the pilot flame shall be adjusted to approximately 1/8 inch in height measured from its lowest point to the tip. The burner flame shall be adjusted by means of the needle valve in the base of the burner to give a flame height of 11/2 inches (±1/16 inch) with the stopcock fully open and the air supply to the burner shut off and taped. The 11/2 inch flame height is obtained by adjusting the valve so that the uppermost portion (tip) of the flame is level with the tip of the metal prong (see Figure B) specified for adjustment of flame height. It is an important aspect of the evaluation that the flame height be adjusted with the tip of the flame level with the tip of the metal prong. After inserting the specimen, the stopcock shall be fully opened, and the burner flame applied vertically at the middle of the lower edge of the specimen for 12 seconds (± .2 second) and the burner turned off. The cabinet door shall remain shut during testing.

(3) The afterflame time for each specimen shall be recorded to the nearest 0.2 seconds. After flaming and glowing have ceased, the specimen shall be removed from the cabinet.

(4) After each specimen is removed, the test cabinet shall be cleared of fumes and smoke prior to testing the next specimen.

(5) After both flaming and glowing have ceased, the damaged length shall be measured. The damaged length shall be the distance from the end of the specimen, which was exposed to the flame, to the end of a tear (made lengthwise) of the specimen through the center of the damaged area as follows: The specimen shall be folded lengthwise and creased by hand along a line through the highest peak of the damaged area. The hook shall be inserted in the specimen (or a hole, 1/4 inch diameter or less, punched out for the hook) at one side of the damaged area 1/4 inch from the adjacent outside edge and 1/4 inch in from the lower end. A weight of sufficient size such that the weight and hook together shall equal the total tearing load required in Table 2 shall be attached to the specimen.

(6) A tearing force shall be applied gently to the specimen by grasping the corner of the cloth at the opposite edge of the char from the load and raising the specimen and weight clear of the supporting surface. The end of the tear shall be marked off on the edge and the damaged length measurement made along the undamaged edge. The specific loads applicable to the weight of the test material are contained in Table 2.

TABLE 2-Loads For Determining Damaged Length

*Untreated weight of material being tested-ounces per square yard*	*Total tear weight for determining the damaged length-pounds*
Not exceeding 6.0	0.25
Over 6.0 and not exceeding 15.0	0.50
Over 15.0 and not exceeding 23.0	0.75
Over 23.0	1.00

(7) The damaged length for each specimen shall be recorded to the nearest 0.1 inch.

(d) Report.

(1) The afterflame time and damaged length of the sample unit shall be the average of the results obtained from the individual specimens tested. All values obtained from the individual specimens shall be recorded.

(2) The afterflame time shall be reported to the nearest 0.2 second and the damaged length to the nearest 0.1 inch.
