Foreword 
 
Emirates Authority for Standardization & Metrology (ESMA) has a  national 
responsibility for standardizati on activities in UAE. One of ES MA main 
functions is to issue Emirates S tandards through specialized te chnical 
committees (TCs). 
ESMA through the technical pr ogram of committee "National  Technical 
Committee for Standards of Oil and Gas” have updated the UAE st andard, 
UAE.S 477: 2020 “Diesel Fuel (Gas Oil) - Requirements and test methods”. 
This draft has been circulated to all concerned stakeholders fo r their valuable 
comments. The same was forwarded the final draft was approved a nd issued as 
UAE standard by decision no. (  ) / Year ……, as a mandatory sta ndard 
i m p l e m e n t e d  o n     /    /  2021. The approved UAE Standard will replace and 
supersede the previous version no. UAE.S 477: 2013. UAE STANDARD                 UAE.S 477: 2020

 Diesel	Fuel	(Gas	Oil)	‐	Requirements 	and	test	methods  
1. Scope 
This Emirates Standard is concer ned with characteristics, requi rements and test 
methods of the Diesel fuel (Gas Oil) for use in diesel engines designed to run on 
automotive diesel fuel containing up to 7.0 % (V/V) Fatty Acid Methyl Ester by 
mixing with Biodiesel Fuels (B100). 
 
2. Definition 
Diesel (Gas Oil): is a liquid petroleum product composed of a m ixture of 
hydrocarbons and complying with this standard specification, fo r satisfactory, 
ignition and combustion under the condition existing in cumbust ion chamber, 
which may be enhanced by certain additives for improving its qu ality.

 4.5 It should comply with the pr operties and requi rements cover ed by Table  of 
“The Characteristics and Require ments and Test Methods for Dies el Fuel”. 
 
5. Sampling Method 
Samples should be obtained from fuel pumps and storage tanks fo r inspection 
and tested in accordance with sta ndard of sampling listed in cl ause (3.10) . 
 
6. Testing and Inspection 
Inspection and testing of sampl es for determining the character istics' and 
requirements which mentioned in, the Table of Characteristics a nd Requirements 
for Diesel, are made according to the methods listed also in cl a u s e  3  o f  t h i s  
standard. 
 
7. Terms of Technical Applications 
Diesel is deemed in accordance with this standard if the result s of tests and 
inspection of the sample taken as indicated in the testing meth od referred to 
under clause (3.10) are found in c ompliance with the characteri stics and 
requirements mentioned under clause (4)  and if found inconsistent with one or 
more of such characteristics it  will be then deemed noncomplian t. UAE STANDARD                 UAE.S 477: 2020
