2 vibration standards Easier to share experiences with others. Easier to compare measurement values with other Simplifies contract writing Facilitates acceptance test2018 11 13 Energiforsk vibration in nuclear application 2018, ISO standards Anders N remark32018 11 13 Energiforsk vibration in nuclear application 2018, ISO standards Anders N remarkDo weneedstandards ? balancing standards Makes it easier (possible) to build a complete Machine from components from different manufacturer turbine generator, motor gearbox compressor, motor coupling pump. Facilitate discussion between customer and manufacturer facilitate writing of specifications(for customer) makes it easier for a manufacturer to explain balancing procedure and criteria facilitate customer control of balancing Good balancing standards will result in an improved quality of balancing and that will result in improved vibration behaviour of machines in situ 4 ISO Organization and general information.
