3、sphateester-based fire-resistant fluids used in steam turbine electro-hydraulic control(EHC)applications.Users may also review ISO 11365 and other related publications for additional information(1-5).21.Scope1.1This guide provides recommendations to achieve safeand reliable operation of EHC systems,
4、recommended levelsfor required corrective action,and suggested managementpractices.1.2 The recommended set of physical and chemical proper-ties of triaryl phosphate esters and their limits have beenselected based on past operating experience with various fluids(primarily xylylated and butylated tria
5、ryl phosphate esters)used in different EHC system designs under different operatingand environmental conditions.1.3This guide is not intended to replace Original Equip-ment Manufacturer(OEM)specifications but rather supportusers experiencing operating problems by recommending lim-its based on existi
