ISO/TC/108/SC1 CD 7475(Mechanical Vibration-Balancing Machines-Enclosure and Other Safety Measures for the Measuring Station)

밸런싱기계의 안전장치에 관한 ISO 7475의 1차개정안에 대하여

This first ISO/CD 7475 is a proposed revision of ISO 7475-1984, which specifies requirements for enclosures and other safety measures used to minimize mechanical hazards produced by the rotor in the measuring station of centrifugal (rotational) balancing machines. The hazards are associated with the operation of balancing machines under a variety of rotor and balancing conditions. This standard defines different classes of protection that enclosures and other protective features have to provide and describes the limits of applicability for each class of protection. At the meeting held at AFNOR in Paris in June 1999, ISO/TC 108/SC1/WG 12 agreed to prepare a first ISO Committee Draft (CD) and circulate to the member bodies for vote and comment by 3 March 2000 since publication as an International Standard requires approval by at least 75% of the member bodies casting a vote. The results of the ballot on this first ISO/CD 7475 was positive so that it will be prepared as an ISO/DIS (ISO/DIS 7475) and discussed in a meeting of ISO/TC 108/SC1 at BSI, London, u.K. in March 2000. Contents of this ISO/CD 7475 with some member comments accounted is briefly described in what follows.
