Hand Held Tool Ergonomics Standards

Hand held tool ergonomic standards in this selection of standards pertain to the measurement and test methods for vibration and shock from hand held tools. They cover drills, impact wrenches, grinders, and forestry equipment such as chainsaws, brush cutters and other groups of handheld tools. Transmission of vibration, the size, weight, presence or absence of handles and their position all factor into elements of the design, selection and use of hand tools. Good resources for hand tool ergonomics are available on the OSHA site that consider hazards in general industry and specific settings such as shipyards, marine terminals, and construction. NIOSH Publication No. 2007-122: Simple Solutions: Ergonomics for Construction Workers provides useful information on some of the conditions or injuries that result from hand tools and offers solutions and recommendations on making work with hand tools easier and safer.

ISO/TS 15694:2004

Mechanical vibration and shock - Measurement and evaluation of single shocks transmitted from hand-held and hand-guided machines to the hand-arm system

ISO/TS 15694:2004 specifies methods for measuring single shocks at the handle(s) of hand-held and hand-guided machinery characterized by a maximum strike rate below 5 Hz. ISO/TS 15694:2004 also defines additional requirements for the measuring instrumentation which is necessary for the evaluation of shocks. The aim is to facilitate the gathering of emission and human exposure data in order to provide a basis for emission declaration and for the future development of exposure risk criteria. However, ISO/TS 15694:2004 does not provide methods for the interpretation of the potential human effects of single shocks. It is therefore a basis for measurement and evaluation of emission of single shocks from hand-held and hand-guided machinery but does not cover the evaluation of human exposure.

The aim of the round-robin test was to establish a test method that could meet the requirement of ISO 20643 for measurement of vibration emissions in three directions, for accordance with the planned-to-be-revised ISO 8662-4.
