Overview
Occupants of vehicles and mobile machinery are exposed to mechanical vibrations that can affect their well-being, performance and, under certain circumstances (by damaging the spine), their health and safety. This is why seats that reduce the transmission of whole-body vibration are used. A suspension seat is the last element in front of the driver that provides suspension. Special measurement standards with which the vibration-reducing properties of a seat can be quantified are used to develop such seats. This DIN-EN-ISO standard contains basic requirements for a laboratory method for measuring the transmission of vibrations from a vehicle via the seat to the occupant. This allows test results obtained by different laboratories for similar vibrating seats to be compared with each other. The basic seat test procedure specified in this standard simulates the normal use of a vehicle or mobile machine. It also specifies requirements for the measuring equipment, including a measuring disk for mounting the vibration transducers, as well as procedures for assessing the measurement results and for documenting them. An informative annex describes an assessment of the acceleration that occurs when impacting the end stops of the seat suspension (suspension travel limiters) if excursion is exceeded. This is important, for example, for seats in off-road vehicles where occasional strong impacts are to be expected. A further informative annex describes an example of a stochastic test excitation vibration. The two amendments from 2008 and 2012 have been incorporated into this new version of the 1994 standard to make it easier to read. The text has also been editorially revised. The International Standard on which this German standard is based has been prepared by ISO/TC 108/SC 4 "Human exposure to mechanical vibration and shock" in collaboration with CEN/TC 231 "Mechanical vibration and shock". CEN has adopted it unchanged as a European Standard. The responsible German committee is Committee NA 001-03-07-01 (NALS/VDI C 7.1) "Ganzkörper-Schwingungen" ("Whole-body vibration").
