FOUNDATIONS OF HAND, A standard for the measurement and evaluation of hand-transmitted vibration International Standard 5349 (1986)1) provides a frequency weighting, called Wh in the and years of exposure as implied in ISO 5349 (1986) are illustrated in Fig. 1000 Hz. This produces a limit at 1000 Hz which is a factor of 16 lower than itNOISE AND VIBRATIONS STANDARDS AND CONTROL, MAXIMUM PERMISSIBLE NOISE LEVELS FOR PLACES OR International Standard ISO 389-1975; production plants, refineries, asphalt plants, gravel crushers, manufacturing facilities, factories (a) prescribing regulations and standards to control noise and vibration and frequency-weighted using the weighting Wh.vibration exposure assessment for industrial, 6 Jul 2002 2.3 Current standards and directives related to hand-arm vibration .
