4 Draft for Comments Only Doc.: PCD 25(200)C IS: 532(Part 5) BUREAU OF INDIAN STANDARDS Draft Indian Standard SPECIFICATION FOR FIRE RESISTANT HYDRAULIC FLUIDS PART 5 ORGANIC ESTER TYPE FOREWORD (Formal clauses will be added later) The use of fire resistant Hydraulic fluid is increasing due to a growing awareness of the dangers inherent in using mineral oil for applications where there is fire risk. There are mainly four types of fire resistant hydraulic fluid (FRHF) namely, dilute emulsion, invert emulsion, water glycols and synthetic fluids In synthetic fluids, FRHF based on phosphate esters are more commonly used The manufacturers are recommending use of Fire Resistant Hydraulic Fluid organic ester type to be used in machineries working below ground mines. They have high film strength and good lubricant on performance. Because of high thermal stability they can operate at temperatures up to C depending upon the system design. Other parts of the standard published so far are as follows: IS 532 (Part 1) : 1983 (Part 2) : 1983 (Part 3) : 1983 (Part 4) : 1983 Dilute emulsions for powered supports. Invert emulsions (water-in-oil) type water glycol type Phosphate esters type. Selection and used of the fire resistant hydraulic fluid are covered in IS 531 : 1983 while determination of the fire resistant characteristic is given in IS 895 : 195. In the preparation of this standard considerable assistance has been derived from ISO standard No and Luxembourg report. For the purpose of deciding whether a particular requirement of this standard complied with, the final value, observed or calculated expressing the result of test or analysis, shall be rounded off in accordance with IS 2 : 1960 ' Rules for rounding off numerical values(revised) '.
