1、Designation: F833 11Standard Consumer Safety Performance Specification forCarriages and Strollers1This standard is issued under the fixed designation F833; the number immediately following the designation indicates the year of originaladoption or, in the case of revision, the year of last revision.
2、A number in parentheses indicates the year of last reapproval. A superscriptepsilon () indicates an editorial change since the last revision or reapproval.INTRODUCTIONThis consumer safety performance specification addresses carriage and stroller incidents that wereidentified by the U.S. Consumer Pro
3、duct Safety Commission (CPSC).The CPSC identified injuries to children associated with the following: stability, brakes, restraintsystems, latches and folding mechanisms, structural integrity, and deaths due to entrapment inopenings of convertible carriage/strollers. By far, the most common injury r
4、esulted when a child fellor climbed out of a stroller because the restraint system was not being used. In response to theincidents data developed by the CPSC, this consumer safety performance specification attempts tominimize the previously listed problems. This specification does not cover carriage
5、s and strollers thatare blatantly misused, although warnings and safety instructions are required to be prominentlydisplayed on or with each carriage or stroller.NOTE 1This consumer safety performance specification is not intended to address incidents andinjuries resulting from the interaction of ot
6、her persons with children in carriages or strollers orincidents resulting from unforeseeable abuse or misuse.This consumer safety performance specification is written within the current state of the art ofcarriage and stroller technology. It is intended that this specification will be updated whenev
7、ersubstantive information becomes available which necessitates additional requirements or justifies therevision of existing requirements.1. Scope1.1 This consumer safety specification establishes safetyperformance requirements, test methods, and labeling require-ments to minimize the hazards to chil
8、dren presented bycarriages and strollers as identified in the introduction. Chil-drens products such as tricycles, bicycles or other similarwheeled products that can be self-propelled by a child are notconsidered carriages or strollers subject to the requirements ofthis standard, even if the item ha
9、s a temporary or permanenthandle.1.2 No carriage or stroller produced after the approval dateof this consumer safety performance specification shall, eitherby label or other means, indicate compliance with this speci-fication unless it conforms to all requirements herein.1.3 The values stated in inc
10、h-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 The following precautionary caveat pertains only to thetest method portion, Section 7, of this consumer safet
11、y speci-fication: This standard does not purport to address all of thesafety concerns, if any, associated with its use. It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.2
