12、,-,- ISO 11393-4:2003(E) iv ISO 2003 All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committee
13、s. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the Inter
14、national Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International St
15、andards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the sub
16、ject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 11393-4 was prepared by Technical Committee ISO/TC 94, Personal safety Protective clothing and equipment, Subcommittee SC 13, Protective clothing. ISO 11393 consists of the following parts, un

20、 part of a series concerned with personal protective equipment designed to reduce the risks arising from the use of hand-held chain-saws. In some areas of work with chain-saws, one third of injuries occur to the hands. However, with different working practices few hand injuries occur. Accidents occu
21、r due to a number of complex reasons, but a common factor is incorrect use of the chain-saw. The importance of correct training and proper use of a chain-saw in preventing accidents cannot be underestimated. In some countries, chain-saw users adopt working practices which together with training make
22、s the use of chain-saw protective gloves unnecessary. These usually include the instruction to hold the chain-saw with both hands and to use the chain brake if it becomes necessary to stop cutting and clear away branches, etc. All parts of the hand (palm, back and fingers) have been shown to be at r
23、isk when using a chain-saw. It is generally accepted for ergonomic and health and safety reasons that protecting the palm and the underside of the fingers is not practicable. Neither is it possible to adequately protect the back of the fingers unless a mitt is used. In this part of ISO 11393, specif
24、ications for the protective coverage and performance of the back of the left-hand glove are given, though the same specifications can be applied to right-hand gloves. Further information is provided in Annex A on risk analysis, glove ergonomics and selection. No personal protective equipment can ens
25、ure a protection against cutting from a hand-held chain-saw. Nevertheless, experience has shown that it is possible to design personal protective equipment which offers a certain degree of protection. As far as is known, all chain-saws are designed for right-handed use and therefore all protective c
26、lothing designs and requirements have assumed right-handed use. Protection cannot be adequate for left-handed use. Different functional principles may be applied in order to give protection. These include a)chain slipping: on contact, the chain does not cut the material, b)clogging: fibres are drawn
27、 by the chain into the drive sprocket and block chain movement, c)chain braking: fibres have a high resistance to cutting and absorb rotational energy, thereby reducing the chain speed. Often more than one principle is applied in chain-saw protective clothing. It should be noted however that none ha
28、s yet been shown to be fully effective in gloves. 100 % Copyright International Organization for Standardization Provided by IHS under license with ISO Licensee=Aramco HQ/9980755100 Not for Resale, 04/16/2007 10:05:19 MDTNo reproduction or networking permitted without license from IHS -,-,- . vi Cop

30、ved 1 Protective clothing for users of hand-held chain-saws Part 4: Test methods and performance requirements for protective gloves 1Scope This part of ISO 11393 specifies the requirements and test methods for gloves that are intended to provide protection against cuts by a hand-held chain-saw, incl
31、uding requirements for identification, marking and information for the user. The method for measurement of protective coverage, the apparatus and the test method for assessing resistance to cutting, and the ergonomic assessment are specified. An informative annex on risk analysis, glove ergonomics a
32、nd glove selection is provided. 2Normative references The following referenced documents are indispensable for the application of this document.
