5. Title, number of pages  and language(s)  of the notified document:  DRS 351: 2017; 
Lubricating oils for turbines – Specification (27 page(s), in English)    
6. Description of content:   
This Draft Rwanda Standard specifies the minimum requirements for turbine lubricating 
oils (mineral oils and syn thetic lubricants). It specifies the requirements for a wide variety 
of turbines for power generation, including steam turbines, gas turbines, combined -cycle 
turbines with a common lubrication system and hydraulic (water driven) turbines.  
This document doe s not specify the requirements for wind turbines.  
This document is applicable to drive rotating equipment, such as pumps and compressors.  
It is also applicable to lubrication for complex auxiliary systems including hydraulic 
systems, gear boxes and couplin gs.
