Remove the covering from the doll, plush toy or soft toy and test it in accordance with the following method:
1 This method covers the evaluation of the flammability of outer coverings of dolls, soft toys, plush toys, and any other product for use by a child in play, that are covered with a flat or raised fibre textile material or natural fur, including dolls’ clothing. In this Schedule, the term “raised fibre surface” means a napped, pile, tufted, flocked or similar surface.
2 Cut specimens from the outer covering and prepare them by brushing the raised fibre surface, by laundering if they have a flame-retarding finish, and by drying. Hold each dried specimen at a 45° angle in the specimen holder of the flammability tester. Apply a standardized flame to the surface of the specimen near the lower end for one second. Record the time that is required for flaming to proceed up the specimen over a distance of 127 mm (5 inches).
3 (1) Flammability tester described in section 1 of Schedule 6.
(2) Brushing device described in section 2 of Schedule 6.
(3) Laboratory drying oven.
(4) Desiccator that is 250 mm (9.8 inches) in diameter.
(5) Calcium chloride, anhydrous.
(6) Butane, cp.
(7) A commercially available detergent.
(8) Mercerized cotton sewing thread No. 50.
4 (1) Select five test specimens, each measuring 51 mm by 152 mm (2 inches by 6 inches) from the part of the outer covering that burns most rapidly.
(2) When possible, in order to select the specimens that burn most rapidly, determine the direction in which to cut the specimens and the part of the outer covering from which to select the specimens. Do this by making preliminary trials, in accordance with the 45° angle test, with specimens cut in different directions and from different locations on the outer covering. Cut the test specimens in the chosen direction and from the chosen location on the outer covering. For textiles that have a raised fibre surface, the long dimension usually is in the direction of the lay of the surface fibres.
(3) Pieces may be removed and reassembled in the specimen holder in the same manner as in the original assembly, to the extent that the pieces are of such a size that they can be securely held in place by the specimen holder, if the outer covering is an assembly and a portion of the outer covering, including any seams, cannot be removed from the assembly in a size large enough to provide the required specimen.
(4) If the outer covering is known to have a flame-retarding finish or if preliminary testing indicates that such a finish may be present, ensure that it is laundered in accordance with section 5.
5 (1) Precondition outer covering samples that are known to have or that are suspected of having a flame-retarding finish applied to them by subjecting them to the washing and drying procedure described in this section.
(2) Prepare a bath solution that consists of water that has a hardness of not greater than 324 mg (5 grains) of calcium carbonate per 4.5 L (1.0 imperial gallons) in an amount 30 times the weight of the sample from which the specimens are to be taken and a commercially available detergent in an amount equal to 15% of this weight. Ensure that the temperature of the bath solution is from 35°C to 38°C inclusive (95°F to 100°F).
(3) Immerse the sample and allow it to soak for 3 minutes. Work it gently by hand for 2 minutes, squeezing the bath solution through the part of the sample to be tested.
(4) Rinse the sample three times in water that has a hardness of not greater than 324 mg (5 grains) of calcium carbonate per 4.5 L (1.0 imperial gallons) in an amount 30 times the weight of the sample. Ensure that the temperature of the rinse water is 27°C (80°F). Immerse and gently squeeze the sample in the first rinsing bath for 1 minute and in the second and third baths for 2 minutes each.
(5) Remove excess water from the sample after each bath by squeezing gently. After the final rinsing bath blot out as much moisture as possible using paper towels or cotton terrycloth.
(6) Lay the sample flat to dry at ambient temperature, namely, from 18°C to 24°C inclusive (65°F to 75°F).
Preparation of Specimens
6 (1) Mark out five specimens, each 51 mm by 152 mm (2 inches by 6 inches), on the reverse side of the sample. Mark the longer dimension in the direction in which burning is most rapid, as established in the preliminary trials referred to in subsection 4(2). Identify the end of each specimen toward which flame spread is most rapid by attaching a staple to it. Cut the specimens from the outer covering.
(2) Brush each specimen that has a raised fibre surface once against the lay of the surface fibres with the brushing device illustrated in Figure 2 of Schedule 6. Specimens that do not have a raised fibre surface do not require brushing.
(3) Clamp each specimen individually in the specimen holders of the flammability tester illustrated in Figure 1 of Schedule 6. The stapled end is to be in the upper position during the test to ensure that the specimen is mounted in the direction in which burning is most rapid. Dry the mounted specimen in a horizontal position in an oven for 30 minutes at 105°C (221°F) or for 120 minutes at 75°C (167°F). Remove it from the oven and place it until cool in a desiccator over anhydrous calcium chloride for at least 15 minutes and not more than 2 hours.
7 (1) Adjust the position of the rack of the flammability tester with a holder and trial specimen (not a prepared specimen) so that the tip of the indicator touches the surface of the specimen.
(2) Open the control valve of the fuel supply and allow approximately 5 minutes for the air to be driven from the fuel line. Ignite the gas and, with the door closed as far as possible, adjust the flame to a length of 16 mm (5/8 inch) measured from its tip to the opening in the gas nozzle.
(3) Remove a mounted specimen from the desiccator and place it in position on the rack in the chamber of the flammability tester. Ensure that the flame impinges on the test specimen within 45 seconds after the time it is removed from the desiccator. String the stop cord (mercerized cotton sewing thread No. 50) through the guides in the upper plate of the specimen holder, across the top of the specimen, through the guides at the rear of the chamber and through the guide ring. Attach the weight to the cord close to and just below the guide ring.
(4) Close the door of the flammability tester. Set the stop watch to zero. Conduct the test in a draft-free room with the flammability tester at room temperature.
(5) Bring the starting lever over to the extreme right and release it. This starts the timing mechanism and applies the flame to the specimen for a period of one second. Timing is automatic, starting on the application of the flame and ending when the weight is released by the burning of the stop cord.
(6) Record the flame spread time for each specimen.
Interpretation of Results
8 (1) A specimen that exhibits either base burning or surface burning of sufficient intensity to sever the stop cord in 7 seconds or less is considered to have failed the test.
(2) Test five additional specimens if one of the five specimens fail. If two out of 10 specimens fail, the doll, plush toy or soft toy does not meet the test requirement.
