1、Designation: F833 13aStandard 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 Pr
3、oduct Safety Commission (CPSC).The CPSC identified injuries to children associated with the following: stability, brakes, restraintsystems, latches and folding mechanisms, structural integrity, cords, wheel detachment, and deathsdue to entrapment in openings of convertible carriage/strollers. In res
4、ponse to the incident-datacompiled by the CPSC, this consumer safety performance specification attempts to minimize thepreviously listed problems. This specification does not cover carriages and strollers that are blatantlymisused, although warnings and safety instructions are required to be promine
5、ntly displayed on orwith each carriage or stroller.NOTE 1This consumer safety performance specification is not intended to address incidents andinjuries resulting from the interaction of other persons with children in carriages or strollers orincidents resulting from unforeseeable abuse or misuse.Th
6、is 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 wheneversubstantive information becomes available which necessitates additional requirements or justifies therevision
7、 of existing requirements.1. Scope1.1 This consumer safety specification establishes safetyperformance requirements, test methods, and labeling require-ments to minimize the hazards to children presented bycarriages and strollers as identified in the introduction. Chil-drens products such as tricycl
8、es, 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 has a temporary or permanenthandle.1.2 No carriage or stroller produced after the approval dateof this consumer s
9、afety 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 inch-pound units are to be regardedas standard. The values given in parentheses are mathematicalconversions to SI
10、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 safety speci-fication: This standard does not purport to address all of thesafety concerns, if any, associated with
11、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.

(3-mm) thick vinyl floor covering,unless test instructs differently.4.2 The unit shall be completely assembled, unless other-wise noted, in accordance with the manufacturers instructions.4.3 No testing shall be conducted within 48 h of
35、manufac-turing.4.4 The product to be tested shall be in a room with anambient temperature of 73 6 9F (23 6 5C) for at least 1 hprior to testing. Testing shall then be conducted within thistemperature range.4.5 All testing required by this specification shall be con-ducted on the same unit with the e
36、xception of 7.2, where a newunit can be used if the unit frame permanently deforms.5. General Requirements5.1 There shall be no hazardous points or edges as definedby 16 CFR 1500.48 and 16 CFR 1500.49 before and aftertesting to this consumer safety specification.5.2 There shall be no small parts as
37、defined by 16 CFR 1501before testing or liberated as a result of testing to thisspecification.5.3 The paint and surface-coating on the product shallcomply to 16 CFR 1303.5.4 Prior to testing, any exposed wood parts shall be smoothand free of splinters.5.5 Latching Mechanisms:5.5.1 Any unit that fold
38、s shall have a latching device orother provision in the design that will prevent the unit fromunintentional folding when properly placed in the manufactur-ers recommended use position. Products with latching devicesfor prevention of unintentional folding shall be tested inaccordance with 7.2. During

45、ter probe at any accessible pointthroughout the range of motion of such parts. This excludes theadjustment of accessory items such as storage latches, baskets,etc.NOTE 1The evaluation at any given location is performed with theunderstanding that the probes are allowed to enter the location from anya
46、ngle/direction.5.7.2 Saddle hinge links on 3D fold strollers shall bedesigned and constructed so as to prevent injury fromscissoring, shearing, or pinching.

The interface between canopy rods andcanopy stops are exempt from this requirement if
49、the canopyrod does not pass over or through the final canopy stop. Finalcanopy stops are those that prevent further movement oradjustment of the canopy (see example in Fig. 5). Intermediatecanopy stop positions are not exempt from this requirement.5.7.4 The frame folding action of a 2D fold stroller andconvertible carriage/stroller (carriages are exempted from thisrequirement) shall be designed and constructed so as to preventinjury from scissoring, shearing, or pinching.
