Standard Consumer Safety Specification for Grab Bars and Accessories Installed in the Bathing Area

SCOPE
1.1 This consumer safety specification covers performance requirements, test methods, and levels of performance to ensure satisfactory functioning of the grab bars and accessory items (not including plumbing controls) during reasonable use to assist a person entering, leaving, or moving within the bathing area.  
1.2 This consumer safety specification is intended to reduce the number of accidents by specifying requirements for grab bars and accessories designed to decrease the probability of slips and falls.  
1.3 This consumer safety specification does not address the specific need of gang showers, island tubs, peninsula tubs, sunken tubs, or tubs 6 ft (1.8 m) or longer.  
1.4 This consumer safety specification exempts shower stalls with both interior dimensions of 34 in. (864 mm) or less.  
1.5 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard.  
1.6 The following precautionary caveat pertains only to the test method portion, Section 7, of this specification.  This standard does not purport to address all of the safety problems, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.7 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

INTRODUCTION
This consumer safety specification addresses certain bathing area accidents that were identified by
the U. S. Consumer Product Safety Commission (CPSC), specifically those which might have been
prevented by the presence of adequate grab bars. This specification also addresses the safe
performance required of accessory items installed in the bathing area.
Available data from the National Electronic Injury Surveillance System (NEISS) were studied by
Abt Associates, Inc., with assistance from Researchitects Inc., and reported to the CPSC. This
information was made available to ASTM Task Group F15.03. It was reviewed along with other
information 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 leaving
the tub, while changing between a sitting or standing position, or while moving around in the bathing
area. This specification establishes parameters as to strength, location, and general requirements of
grab bars and accessories to assist movement and reduce hazards in the bathing area.
