Egypt - Mandating the Egyptian Standard ES 4603-2 for producer and importer Egyptian Organization for Standardization and Quality has issued decree mandating that the producers and importers must abide by ES 4603-2.This Standard applies to land-based steam turbines and generators with power outputs greater than 50 MW and a normal operating speed of 1 500 r/min, 1 800 r/min, 3 000 r/min or 3 600 r/min. It is also applicable to steam turbines and/or generators which are directly coupled to a gas turbine (such as for combined-cycle applications). In such cases, the criteria of this part of the standard apply only to the steam turbine and the generator (including synchronizing clutches). ISO 7919-4 and ISO 10816-4 are applicable to the evaluation of the gas turbine vibration. The numerical values specified are not intended to serve as the only basis for judging the severity of vibration. For large steam turbines and generators, it is also common to judge the vibration based on measurements taken on non-rotating parts. For such vibration measurement requirements, see ISO 10816-1 and ISO 10816-2. Worth mentioning is that this standard complies with ISO 10816-2/2009. A transitional period of six months is given to abide by the standard. Proposed date of adoption: 19 March 2016 Proposed date of entry into force: 21 April 2016 Final date for comments: 60 days from the date of the notification |
