14、ommittee PH/3/8 in co-operation with GME/21 and is the English language version of EN ISO 10819 : 1996 Mechanical vibration and shock Hand-arm vibration Method for the measurement and evaluation of the vibration transmissibility of gloves at the palm of the hand, published by the European Committee
15、for Standardization (CEN). It is identical with ISO 10819 : 1996 published by the International Organization for Standardization (ISO). EN ISO 10819 : 1996 was produced as a result of international discussion in which the UK took an active part. The experience gained by organizations in the UK (Heal
16、th and Safety Executive, and Institute of Sound and Vibration Research) whilst developing a test facility, in accordance with the draft standard, showed the standard to be unreliable in a number of ways. At the time of publication, this standard has not been thoroughly tested. There is some evidence
17、 that the standard has been interpreted differently at test houses around the world. It is not clear that results obtained in different test houses are comparable, i.e. use of the standard may not give reproducible test results. Gloves may amplify vibration at low frequencies even though they attenu
18、ate at other frequencies. In the interests of safety, users of this standard are encouraged to draw this problem to the attention of the users of such gloves. The standard is insensitive to large differences in glove performance at high frequencies. This may not be important according to current kno
19、wledge of vascular injury but should not be overlooked, particularly in respect of other injuries. Considerable expertise and experience, and more specialized equipment than is implied, is needed before tests can be carried out in strict accordance with this standard. The UK and Russia disapproved p
20、ublication of this standard. Users of this standard should note that Technical Committee ISO/TC 108/SC 4 has passed a Resolution to update the document taking into account the experience of users. This standard may be subject to early and substantial revision. Cross-references Publication referred t

This European Standa
32、rd shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by December 1996, and conflicting national standards shall be withdrawn at the latest by December 1996. This European Standard has been prepared under a mandate given to C
33、EN by the European Commission and the European Free Trade Association, and supports essential requirements of EU Directive(s). There are five annexes to this standard whereof annex A is normative and annexes B, C, D and ZA are for information only. According to the CEN/CENELEC Internal Regulations,
34、the following countries are bound to implement this European Standard: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Introduction This European Standard was developed
35、 in response to the growing demand to protect people from the risks of vibration damage caused by exposure to hand-transmitted vibration. In the field of personal protective equipment (PPE), gloves are being marketed which are intended to reduce the magnitude of vibration exposure. On present eviden
36、ce, there have been no circumstances in which gloves have been shown to provide adequate attenuation of vibration to prevent vibration injuries. Within the current state of knowledge, gloves do not provide significant attenuation in the frequency range below 150 Hz. Some gloves may provide amplifica
37、tion in this frequency range. Also, the use of gloves might alter the gripping force which would alter the transmission of vibration into the arms thus increasing the risk of damage. However, it must be emphasized that an important purpose of gloves is to keep the hands warm and dry, as this may hel
38、p to limit some vibration-induced effects. This standard describes a method of measuring the vibration transmissibility of gloves in the laboratory, but as far as possible under conditions typical of use at actual working places. The measurement is performed at the palm of the hand and so does not g
39、ive the transmission of vibration to the fingers. However, when evaluating the protective effects of a glove, it must be remembered that in many work situations, vibration is transmitted not only to the palm but also to the fingers. A different measurement procedure will be required to establish the
40、 vibration transmissibility of gloves at the fingers. This standard describes a method of measuring the vibration transmissibility of gloves worn by a test subject. For the measurement of the vibration transmissibility of resilient materials which are used to cover handles of tools or make gloves, E
41、N ISO 13753 should be consulted.

42、ration transmissibility of gloves in terms of vibration transmission from a handle to the palm of the hand in the frequency range from 31,5 Hz to 1250 Hz. The standard is intended to define a screening test for the vibration transmission through gloves. It is recognized that many factors influence t
43、he transmission of vibration through gloves. Therefore the transmissibility value according to this standard is not sufficient to assess the health risk due to vibration. The transmissibility of vibration is measured and reported for two input spectra, which are representative of the vibration of so
44、me tools, and may be reported as a function of frequency. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed hereafter
45、. For dated references, subsequent amendments to or revisions of any of these publications apply to this European standard only when incorporated in it by amendment or revision.
