3、dded editorially in August 2004.INTRODUCTIONThis consumer safety specification addresses certain bathing area accidents that were identified bythe U. S. Consumer Product Safety Commission (CPSC), specifically those which might have beenprevented by the presence of adequate grab bars. This specificat

4、ion also addresses the safeperformance required of accessory items installed in the bathing area.Available data from the National Electronic Injury Surveillance System (NEISS) were studied byAbt Associates, Inc., with assistance from Researchitects Inc., and reported to the CPSC. Thisinformation was

5、 made available to ASTM Task Group F15.03. It was reviewed along with otherinformation appropriate to the subject and became the basis for developing this specification.The information reviewed indicated that slips and falls frequently occur while entering or leavingthe tub, while changing between a

6、 sitting or standing position, or while moving around in the bathingarea. This specification establishes parameters as to strength, location, and general requirements ofgrab bars and accessories to assist movement and reduce hazards in the bathing area.1. Scope1.1 This consumer safety specification

7、covers performancerequirements, test methods, and levels of performance toensure satisfactory functioning of the grab bars and accessoryitems (not including plumbing controls) during reasonable useto assist a person entering, leaving, or moving within thebathing area.1.2 This consumer safety specifi

8、cation is intended to reducethe number of accidents by specifying requirements for grabbars and accessories designed to decrease the probability ofslips and falls.1.3 This consumer safety specification does not address thespecific need of gang showers, island tubs, peninsula tubs,sunken tubs, or tub

10、 of the safety problems,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.
