(Specification)Standard Specification and Test Method for Rear-Mounted Bicycle Child Carriers
Standard Specification and Test Method for Rear-Mounted Bicycle Child Carriers
ABSTRACT
This specification covers rear-mounted bicycle child carriers. It does not cover child carriers mounted in front of handlebars or to the top tube, head tube, or behind the handlebars in front of the rider. The carrier shall be manufactured free of burrs, sharp edges, and sharp points; when present, these shall be properly covered with protective coatings to prevent injuries. In addition, the carrier shall be equipped with a rear reflector, footrests, backrest, armrests, protective devices to prevent contact of hands and feet with moving or movable components of the bicycle, and belt or capturing devices to keep the child from standing in or leaving the carrier. The carrier shall be protected against corrosion, with any plastic or synthetic components stabilized against ultraviolet radiation and resistant to ozone. Tests for high and low temperature resistance, high and low temperature drop, and strength shall be performed and shall conform to the requirements specified. Additional tests for flammability, sharp points, sharp edges, ambient drop, retention system pull, and retention system security may be performed as well.
SCOPE
1.1 This specification covers child carriers that mount to the rear of bicycles in order to transport children or accessory loads with a maximum weight of 18 kg (40 lb). This specification does not apply to child carriers that mount in front of the handlebars, or to the top tube, head tube, or behind the handlebars in front of the rider.Note 1—In the instructions, the manufacturer must warn the rider that a load added to the bicycle will lessen the stability and alter the riding characteristics of the bicycle. This complication is particularly important when riding with children who are near the high end of the weight range.
1.2 The following safety hazards caveat pertains only to the test method portions, Sections 5, 6, and 7, of this specification: This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

lowest point of the underside of the seating area of the carrier
shell at a height of 1.00 6 0.01 m (39.37 6 0.39 in.) above a
