4. Products covered (HS or CCCN where applicable, otherwise national tariff heading. 
ICS numbers may be provided in addition, where applicable) : Mechan ical vibrations 
and shock (ICS : 27.040; 17.160; 29.160.40)  
5. Title, number of pages  and language(s)  of the notified document : Ministerial Decree 
No. 243 for the year 2016 (2 pages, in Arabic) mandating the Egyptian Standard ES 4603 -2 
for Mechanical vibra tion – Evaluation of machine vibration by measurements on rotating 
parts – Part 2 : Land-based steam turbines and generators in excess of 50 MW with normal 
operating speeds of 1 500 r/min, 1 800 r/min, 3 000 r/min and 3 600 r/min (23 pages, in 
Arabic)  
6. Description of content : This Ministerial decree mandates that the producers and 
importers must abide by ES 4603 -2. 
A transitional period of six months is given to abide by the standard.  
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 applica tions). 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 v alues 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 measu rement 
requirements, see ISO 10816 -1 and ISO 10816 -2. 
Worth mentioning is that this standard complies with ISO 10816 -2/2009.  G/TBT/N/EGY/161
