Foreword 
Emirates Authority for Standard ization & Metrology (ESMA) has a  
national responsibility for sta ndardization activities in UAE. One of ESMA 
main functions is to issue Emirat es Standards through specializ ed technical 
committees (TCs). 
 ESMA through the technical progr am of committee "National Tech nical 
Committee for Standards of Oil a nd Gas” have updated the UAE st andard 
no. UAE.S 5018:  2020  “Unleaded Gasoline - Requirements and Test 
Methods”.  
This draft has been circulated to  all concerned stakeholders fo r their 
valuable comments.  The final dr aft was approved and issued as UAE 
standard by decision no. (  ) / Y ear ……, as a mandatory standar d 
implemented on    /   / 2021 . The approved standard  will replace and 
supersedes the previous version no . UAE.S 5018: 2017 .

 Introduction 
Emirates Authority for Standardi zation and Metrology was establ ished by 
Federal Law No. 28 in 2001 as a Na tional Standardization Body.  
Fuel quality plays a prominent role in controlling the emission  l e v e l s  i n  
gasoline vehicle engines. Vehic le exhaust emission is one of th e main source 
of air pollution in cities all over the world. Based on this re ality and with an 
intention of controlling the emission levels, ESMA is working i n parallel to 
improve the standard specifica tions of fuel quality and gaseous  e m i s s i o n  
levels of vehicles.   
In 2002 ESMA had issued the first UAE standard specification of  unleaded 
gasoline, UAE.S 20001:2002, prepare d / proposed by a technical committee 
consisting of specialists and experts representing the Ministry  of Energy, 
National Oil Companies and Envir onmental Bodies. At that time, the use of 
leaded gasoline was phased out in the United Arab Emirates, whe re lead 
compounds were used to improve the  gasoline octane number. Then , unleaded 
gasoline was introduced into the market under the specification  mentioned, 
where also there was a reduction in sulfur levels down to 500 p pm.  
 
ESMA, through the National Tec hnical Committee for Standardizat ion of Oil 
and Gas, made the first revie on this standard with an intentio n to improve the 
characteristics of unleaded gasoline by reducing the total sulf ur content from 
500 ppm to 100 ppm along with other parameters. The updated sta ndard was 
approved and issued a s UAE.S 20001:2006.   
The National Technical Committee for Standardization of Oil and  Gas worked 
on a second review for the unleaded gasoline standard, in light  o f  t h e  
improvement required in gasoline properties.  These changes wil l help the fuel 
to be more compatible with internal combustion engine vehicles provided with 
catalyst converters. The main t echnical changes   made in this new version 
includes reduction of total sulfur content (from 100 ppm to 50 ppm) as well as 
stating clearly in the standard  that it is not allowed to use a ny metallic 
additives to improve the octane n umber other than oxygenated ad ditives 
(MTBE/ETBE/TAME) The new version of the standard is revised as UAE.S 
5018 "Unleaded Gasoline- Requi rements and Test Methods”. 
The National Technical Committee for Standardization of Oil and  Gas worked 
on a second review for UAE Standard of "Unleaded Gasoline – Req uirements 
and Test Method", in light of the improvement required in gasol ine properties.  
These changes will help the fuel to be more compatible with int ernal 
combustion engine vehicles provi ded with catalyst converters ac cording to 
Euro 5, The main technical changes made in this new version inc ludes 
reduction of total sulfur content (from 50 ppm to 10 ppm) as we ll as well as 
other properties of Benzene,  aromatics and olefins.

 Unleaded Gasoline - Requ irements and Test Methods 
 
1 Scope 
This Emirates standard specifies  requirements and test methods for 
marketed and delivered unleaded gasoline fuels (ULG). It is app licable for 
use in spark ignited engine veh icles designed to run on ULG. 
This fuel type contain three grades according to octane numbers -viz, 
regular 91, special 95 and s uper 98 in Table of Annex 1.
