Evaluation of antivibration glove test protocols associated with the revision of ISO 10819.
Effects of modifying the palm adapter geometry on ISO 10819 antivibration glove test results were investigated. 30 rigid acrylic adapters were designed, fabricated, and evaluated. The length of the adapters that met ISO 10819 requirements covered 70-80% of the width of the palm. The upper curvatures of the adaptors were greater than or equal to the radius specified in ISO 10819:1996. Glove vibration transmissibility tests were conducted using a constant velocity vibration input with a value of 0.01 m/s in each third octave frequency band from 16-1,600 Hz (F spectrum). Glove vibration transmissibility results obtained using the M (16-400 Hz) and H (100-1,600 Hz) spectra specified in ISO 10819:1996 were compared to similar results using the constant velocity spectrum. The results obtained from the constant velocity spectrum, when divided into the M and H frequency ranges, were nearly the same as those obtained from the ISO 10819 M and H spectra. Test subject training was required to ensure reliable glove vibration transmissibility results. The measured transmissibility values obtained with the M, H, and F spectra were all higher at the beginning of the test program. The transmissibility values decreased and approached lower limiting values as the test subjects became more experienced.
