AMERICAN NATIONAL STANDARDS ON ACOUSTICS The Acoustical Society of America (ASA) provides the Secretariat for Accredited Standards Committees S1 on Acoustics, S2 on Mechanical Vibration and Shock, S3 on Bioacoustics, S3/SC 1 on Animal Bioacoustics, and S12 on Noise. These comm

8、ittees have wide representation from the technical community (manufacturers, consumers, trade associations, organizations with a general interest, and government representatives). The standards are published by the Acoustical Society of America as American National Standards after approval by their

9、respective Standards Committees and the American National Standards Institute (ANSI). These standards are developed and published as a public service to provide standards useful to the public, industry, and consumers, and to Federal, State, and local governments. Each of the Accredited Standards Com

10、mittees (operating in accordance with procedures approved by ANSI) is responsible for developing, voting upon, and maintaining or revising its own Standards. The ASA Standards Secretariat administers Committee organization and activity and provides liaison between the Accredited Standards Committees

11、 and ANSI. After the Standards have been produced and adopted by the Accredited Standards Committees, and approved as American National Standards by ANSI, the ASA Standards Secretariat arranges for their publication and distribution. An American National Standard implies a consensus of those substan

12、tially concerned with its scope and provisions. Consensus is established when, in the judgment of the ANSI Board of Standards Review, substantial agreement has been reached by directly and materially affected interests. Substantial agreement means much more than a simple majority, but not necessaril

13、y unanimity. Consensus requires that all views and objections be considered and that a concerted effort be made towards their resolution. The use of an American National Standard is completely voluntary. Their existence does not in any respect preclude anyone, whether he or she has approved the Stan

14、dards or not, from manufacturing, marketing, purchasing, or using products, processes, or procedures not conforming to the Standards. NOTICE: This American National Standard may be revised or withdrawn at any time. The procedures of the American National Standards Institute require that action be ta

Those procedures have been accredited by the American National Standards Institute (ANSI). The Scope of Accredited Standards Committee S2 is as follows: Standards, speci

30、tolerance and comfort. This standard is an identical national adoption of ISO 10819:2013 which was prepared by Technical Committee ISO/TC 108/SC 4, Human exposure to mechanical vibration and shock. This standard is a revision of ANSI S2.73-2002 (R 2007) / ISO 10819:1996. This revision incorporates s

38、2.73-2014 / ISO 10819:2013 vi 2014 Acoustical Society of America All rights reserved Introduction Because of the growing demand to reduce health risks associated with exposure to hand-transmitted vibration, gloves with vibration-reducing materials are often used to attenuate vibration transmitted to

39、 the hands. These gloves normally provide little reduction in hand-transmitted vibration at frequencies below 150 Hz. Some gloves can increase the vibration transmitted to the hands at these low frequencies. Gloves with vibration-reducing materials that meet the requirements of this American Nationa

40、l Standard to be classified as an antivibration glove can be expected to reduce hand-transmitted vibration at frequencies above 150 Hz. These gloves can reduce but not eliminate health risks associated with hand-transmitted vibration exposure. Field observations indicate that gloves with vibration-r

41、educing materials can result in positive and negative health effects. Positive health effects can occur with gloves that reduce finger tingling and numbness and that keep the hands warm and dry. Negative health effects can occur with gloves that increase the vibration transmitted to the hands at low

42、 frequencies and that increase hand and arm fatigue because they increase the hand grip effort required to control a vibrating machine. Gloves tested in accordance with the requirements of this American National Standard are evaluated in a controlled laboratory environment. The actual vibration atte

43、nuation of a glove in a work environment can differ from that measured in a controlled laboratory environment. Vibration transmissibility measurements made in accordance with the requirements of this American National Standard are performed only at the palm of the hand. The transmission of vibration

44、 to the fingers is not measured. When evaluating the effectiveness of a glove with a vibration-reducing material used to reduce vibration transmitted to the hand, vibration transmission to the fingers should also be assessed. However, research subsequent to the publication of this American National

45、Standard is needed to develop a measurement procedure that can be used to measure the vibration transmissibility of gloves at the fingers. The measurement procedure specified in this American National Standard only addresses glove properties that can reduce health risks associated with hand-transmit

46、ted vibration in work environments. It does not address glove properties necessary to reduce other hand-related health and safety risks in work environments. The measurement procedure specified in this American National Standard can also be used to measure the vibration transmissibility of a materia

47、l that is being evaluated for use to cover a handle of a machine or for potential use in a glove.

48、urement and evaluation of the vibration transmissibility of gloves at the palm of the hand (a nationally adopted international standard) WARNING This American National Standard defines a screening test procedure for measuring the vibration transmission through gloves with an embedded vibration-reduc

Therefore, use the vibration transmissibility values obtained in accordance with this American National Standard with caution in the assessment of the vibration-reducing effects of gloves. 1 Scope This American National Standard specifies a method for the laboratory measurement, data analysis, and reporting of the vibration transmissibility of a glove with a vibration-reducin
