GB/T 18703-2021 Mechanical vibration and shock—Hand-arm vibration—Measurement and evaluation of the vibration transmissibility of gloves at the palm of the hand

Scope

This standard specifies the measurement and evaluation methods for the vibration transmission rate of gloves with vibration-reducing materials (applied to the palm, fingers, and thumb). Specifically, it describes the laboratory measurement, data analysis, and reporting methods for the vibration transmission rate of gloves based on the transmission of vibration from the handle to the palm at a 1/3 octave band center frequency range of 25 Hz to 1250 Hz.
The measurement methods specified in this standard can also be used to measure the vibration transmission rate of vibration-reducing materials applied to machine handles or potentially used in gloves. However, even if the materials applied to the handle meet the requirements of this standard according to the measurement results, this does not imply that they are anti-vibration covers. If materials measured in this manner are used in gloves, the gloves must undergo measurement according to the measurement steps specified in this standard and meet the vibration-reducing performance requirements of this standard before they can be deemed anti-vibration gloves.
Note: GB/T 19739[1] specifies methods for screening vibration-reducing materials used on machine handles and in gloves.
