(Specification)Standard Specification and Test Method for Rear-Mounted Bicycle Child Carriers
Standard Specification and Test Method for Rear-Mounted Bicycle Child Carriers
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 , and7, 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.

shall be adequate for the seated child at the upper range of the

to determine whether there are any adverse affects on the
strength and function of the carrier under conditioned environ-
ments.

shell at a height of 1.00 6 0.01 m (39.37 6 0.39 in.) above a
concrete floor. The bottom of the fixture has a pivoting device
that allows the fixture to rotate until it contacts the floor. The
mass of the drop arm is 11+0.5−0 kg (24+1.0−0 lb).
Within 1 min after removal from the conditioned environment,
release the carrier under gravity from rest to one side or the
other onto a flat concrete surface, as if the bicycle to which it
was mounted fell over.
5.5.3 Examine the carrier for damage or distortion that
could affect the safety or function of the carrier.
5.5.4 Damage or distortion that could affect the safety or
function of the carrier constitutes failure of the test.
