Current through Register Vol. 46, No. 12, March 20, 2024

(a) Standard conditions for testing. Flame tests shall be performed under or upon immediate removal from standard atmospheric conditions and on specimens in moisture equilibrium under standard atmospheric conditions.

(b) Preconditioning. In the event of dispute concerning the results of tests that may be affected by the moisture content, the material shall be preconditioned by being brought to moisture equilibrium with an atmosphere having a relative humidity of not over 10 percent and a temperature not over 125° F. (52° C.). The material shall then be brought to moisture equilibrium under standard atmospheric conditions and then tested.

(1) Test specimen. Test specimens to be leached shall be of the following dimensions:

(i) Each flooring material test specimen shall be a 9 inch by 9 inch (+-1/16 inch) section of the flooring material to be tested.

(ii) Wall and top material test specimens shall be rectangles of cloth 2 3/4 inches by 12 inches. (+- 1/16 inch) with the long dimensions parallel to either the warp or filling directions of the material.

(2) Apparatus. The following apparatus shall be used in the leaching process.

(i) Water container or tank of such shape and size that the specimen can be submerged therein with all surfaces of the specimen having full access to the water. For cloth specimens the container shall allow not less than 1/2 gallon of water for each square foot of specimen. The water shall be changed by a continuous flow or by emptying and refilling so that there shall be at least six complete changes of water in a 72-hour period.

(ii) Means of maintaining water at a temperature of 60° F. to 70° F. (15.5° C. to 21.1° C.) and a pH of 6.0 to 8.0 during the test.

(iii) Means for holding the specimen submerged throughout the leaching period.

(3) Procedure. The specimens shall be immersed in water at a temperature of 60° F. to 70° F. (15.5° C. to 21.1° C.) and a pH of 6.0 to 8.0 for 72 hours. The specimen shall then be removed, air-dried, and brought to standard atmospheric conditions prior to further testing.

(d) Accelerated weathering. Tests in sections 80-8.6 and 80-8.7 shall be performed both before and after accelerated weathering.

(1) Test specimen. Test specimens to be weathered shall be of the following dimensions:

(i) Each flooring material test specimen shall be a 9 inch by 9 inch (+-1/16 inch) section of the flooring material to be tested.

(ii) Wall and top material test specimens shall be rectangles of cloth 2 3/4 inches by 12 inches (+-1/16 inch) with the long dimensions parallel to either the warp or filling directions of the material.

(2) Apparatus. The following apparatus shall be used in the accelerated weathering process:

(i) Vertical carbon arc mounted at the center or a vertical cylinder. The arc shall be designed to accommodate either two or three pairs of carbons but shall burn only one pair at a time, automatically transferring from one pair to another as the carbons are consumed. The carbons shall be sunshine-cored and copper-coated, No. 22 for the upper pair and 13 for the lower pair. The arc shall be operated on 60 amperes and 50 volts across the arc for alternating current and on 50 amperes and 60 volts across the arc for direct current.

(ii) A rotating rack with holder in which the specimens are suspended vertically and normally to radiation from the arc with the center of the face of the specimen at a radial distance of approximately 18 inches from the arc.

(iii) Water-spray nozzles shall be mounted horizontally (the water-spray assembly vertically) in the test chamber inside the specimen rack and so placed that the water shall strike the specimens evenly over their entire length in the form of a fine spray in sufficient volume to cover specimens immediately on impact. The apparatus shall be so operated that the specimens are exposed to successive cycles of 102 minutes of light without spray and 18 minutes of light with spray.

(iv) Means for maintaining the required temperature of water in the spray.

(v) Means of maintaining the required pressure of water entering the spray.

(vi) Means for delivering the required quantity of water per spray nozzle to the specimen.

(vii) Exhaust fan to ventilate the arc effectively.

(viii) Black panel thermometer unit for measuring the temperature within the machine. This unit shall consist of a metal panel to the base of which is attached the sensitive portion of a bimetallic dia-type thermometer. The entire base is then coated twice with long lasting baked enamel paint.

(3) Procedure. The following procedure shall be followed:

(i) The rack shall rotate about the arc at a uniform speed of one revolution per minute.

(ii) The temperature of water in the spray shall be 80° +- 10° F. (26.7° +- 5.6° C).

(iii) The pressure of the water entering the spray shall be 1-18 psi inclusive.

(iv) The quantity of water delivered to the specimen shall be.12 to.25 gallons, inclusive, per hour per spray nozzel.

(v) The black panel temperature at the exposure plane of the specimen rack shall be 155° +-10° F. (68° +- 5.7° C.) When measured in the following manner:

(a) Before reading the temperature, the machine shall be full of specimens and shall be in operation long enough for thermal equilibrium to be established. The black panel shall be mounted in the test-panel rack and readings taken at the point where water spray is not striking the panel.

(vi) The specimen shall be suspended on the rotating rack without tension and in such a way that the ends or corners cannot curl. The long dimension of the specimen shall be in the vertical position and shall be indicated on the reverse side of the cloth. No test portion of the specimen shall be over seven inches above or below the horizontal plane of the arc.

(vii) The specimen shall be exposed to normal radiation from the arc for 100 hours.

(viii) At the end of the exposure period, the specimen shall be removed from the machine, allowed to dry, and brought to standard atmospheric conditions prior to further testing.
