(b) Impact test—(1) Application.Except as provided in paragraph (b)(4) of this ction, toys having a weight of less than 10.0 pounds ±0.01 pound (4.6 kilograms) shall be subject to this test. 炮仗简笔画(2) Impact medium.The impact medium shall consist of a1/8-inch (0.3-centimeter) nominal thickness of type IV vinyl-composition tile, composition 1—asbestos free, as specified by paragraphs 1.2 and 3.1.4 of Interim Amendment-1(YD), dated November 14, 1979, to the Federal Specification entitled Tile, Floor: Asphalt, Rubber, Vinyl, Vinyl-Asbestos, SS-T-312B, dated October 10, 1974,1 over at least a 2.5-inch (6.4-centimeter) thickness of concrete. The impact area shall be at least 3 square feet (0.3 square meter). The Commission recognizes that this specified impact medium is the equivalent of, and will yield the same impact test results as, a surface covered with vinyl-asbestos tile meeting the requirements of Federal Specification SS-T-312A. (3) Testing procedure.except as provided in paragraph (b)(4) (i) and (ii) of this ction, the toy shall be dropped four times from a height of 3 feet ±0.5 inch (0.92 meter) onto the impact medium described in paragraph (b)(2) of this ction. The toy shall be dropped in random orientation. After each drop, the test sample shall be allowed to come to rest and shall be examined and evaluated before continuing. (4) 酱油拉面Large and bulky toys.螺旋藻粉(i) A toy that has a projected ba area of 400 or more square inches (2,560 or more square centimeters) shall be tested for impact in accordance with paragraph (b)(4)(iii) of this subction. The ba area for toys having permanently attached legs shall be measured by calculating the area enclod by straight lines connecting the outermost edge of each leg of the perimeter. 自信的名言警句(ii) A toy that has a volume of more than 3 cubic feet (0.085 cubic meter), calculated by the major dimensions without regard to minor appendages, shall be tested for impact in accordance with paragraph (b)(4)(iii) of this ction. (iii) The toys described in paragraph (b)(4) (i) and (ii) of this ction shall be tested for impact by tipping them over three times by pushing the samples slowly past their centers of balance onto the impact medium described in paragraph (b)(2) of this ction. (c) Bite test—(1) Application.A toy (or component) that is a mouth toy shall be subject to this test. (2) Test equipment—(i) Contact mechanism.The contact mechanism shall be two metal strips or plates each measuring 0.25 inch ±0.002 inch (0.635 centimeter) high and each having a contact edge radius of 0.020 inch ±0.002 inch (0.5 centimeter) for at least a 150-degree cross-ctional arc. A suggested contact mechanism appears in figure 1 of §1500.51. (ii) Loading device.The loading device shall be a scale or force gauge having an accuracy of ±0.5 pound (±225 grams). (3) Testing procedure.The test article shall be placed in the contact mechanism in any reasonable position for a penetration of 0.25 to 0.5 inch (0.64 to 1.27 centimeters), which position utilizes less than 180 degrees of the arc of the contract mechanism, and a test load increasing to 100 pounds ±0.5 pound (45.50 kilograms) shall be evenly applied within 5 conds. This load shall be maintained for an additional 10 conds. (d) Flexure test—(1) Application.This test shall be applied to each component of a toy containing metal wire(s), or other metal material(s), for stiffening or for retention of form if the component can be bent through a 60-degree arc by a maximum force of 15 pounds ±0.5 pound (6.80 kilograms) applied perpendicularly to the major axis of the component at a point 2 inches ±0.05 inch (5 centimeters) from the interction of the component with the main body of the toy or at the end of the component if the component is less than 2 inches ±0.05 inch (5 centimeters) long. (2) Testing procedure.The toy shall be cured in a vi equipped with vi shields that are fabricated from 13-gauge cold-rolled steel or other similar material and that have a 0.375-inch (0.95-centimeter) inside radius. The component shall then be bent through a 60-degree arc by a force applied at a point on the component 2 inches (5 centimeters) from the interction of the component with the main body of the toy or applied at the end of the component if the component is less than 2 inches (5 centimeters) long. The component shall then be bent in the rever direction through a 120-degree arc. This process shall be repeated for 30 cycles at a rate of one cycle per two conds with a 60-cond rest period occurring after each 10 cycles. Two 120-degree arc bends shall constitute one cycle. (e) Torque test—(1) Application—(i) General.A toy with a projection, part, or asmbly that a child can grasp with at least the thumb and forefinger or the teeth shall be subject to this test. 朋友和家庭(ii) Toys with rotating components.Projections, parts, or asmblies that are rigidly mounted on an accessible rod or shaft designed to rotate along with the projections, parts, or asmblies shall be tested with the rod or shaft clamped to prevent rotation. (2) Test equipment—(i) Loading device.The loading device shall be a torque gauge, torque wrench, or other appropriate device having an accuracy of ±0.2 inch-pound (±0.23 kilogram-centimeter). (ii) Clamp.The clamp shall be capable of holding the test component firmly and transmitting a torsional force. (3) Testing procedure.With the toy rigidly fastened in any reasonable test position, the clamp is fastened to the test object or component. A torque of 4 inch-pounds ±0.2 inch-pound (4.60 kilogram-centimeters) shall be applied evenly within a period of 5 conds in a clockwi direction until a rotation of 180 degrees from the original position has been attained or 4 inch-pounds ±0.2 inch-pound (4.60 kilogram-centimeters) exceeded. The torque or maximum rotation shall be maintained for an additional 10 conds. The torque shall then be removed and the test component permitted to return to a relaxed condition. This procedure shall then be repeated in a counterclockwi direction. (f) Tension test—(1) Application—(i) General.Any projection of a toy that the child can grasp with at least the thumb and forefinger or the teeth shall be subject to this test. This test is to be conducted on the same toy that has been subjected to the torque test described in paragraph (e) of this ction. (ii) Stuffed toys and beanbags.A stuffed toy or beanbag constructed of pliable materials having ams (such as fabrics) shall have the ams subjected to 15 pounds ±0.5 pound (6.80 kilograms) of force applied in any direction. (2) Test equipment—(i) Clamps.One clamp capable of applying a tension load to the test component is required. A cond clamp suitable for applying a tension load perpendicularly to the major axis of the test component is also required. (ii) Loading device.The loading device is to be a lf-indicating gauge or other appropriate means having an accuracy of ±0.5 pound (±225 grams). (3) Testing procedure.With the test sample fastened in a convenient position, and appropriate clamp shall be attached to the test object or component. A 15-pound ±0.5 pound (6.80-kilogram) direct force shall be evenly applied, within a period of 5 conds, parallel to the major axis of the test component and maintained for an additional 10 conds. The tension clamp shall then be removed and a cond clamp appropriate for pulling at 90 degrees shall be attached to the test object or component. A 15-pound ±0.5 pound (6.80-kilogram) tensile force shall be evenly applied, within a period of 5 conds, perpendicularly to the major axis of the test component and maintained for an additional 10 conds. (g) Compression test—(1) Application.Any area on the surface of a toy that is accessible to a child and inaccessible to flat-surface contact during the impact test shall be subject to this test. (2) Test apparatus.The loading device shall be a rigid metal disc 1.125 inches ±0.015 inch (2.86 centimeters) in diameter and 0.375 inch (0.95 centimeter) in thickness. The perimeter of the disc shall be rounded to a radius of1/32inch (0.08 centimeter) to eliminate irregular edges. The disc shall be attached to an appropriate compression scale having an accuracy of ±0.5 pound (±225 grams).
