If applicable, name of local government involved (Article 3.2 and 7.2):   
2. Agency responsible: Uganda National Bureau of Standards  
Name and address (including telephone and fax numbers, email and website 
addresses, if available) of agency or authority designated to handle comments 
regarding the notification shall be indicated if different from above:   
3. Notified under Article 2.9.2 [  ], 2.10.1 [  ], 5.6.2 [X], 5.7.1 [  ], other:  
4. Products covered (HS or CCCN  where applicable, otherwise national tariff 
heading. ICS numbers may be provided in addition, where applicable): 
Lubricating Oils ; Lubricating preparations (including cutting -oil preparations, bolt or nut 
release preparations, anti -rust or anti -corrosion preparations and mould release 
preparations, based on lubricants) and preparations of a kind used for the oil or grease 
treatment of textile materials, leather, furskins or other materials, but excluding 
preparations containing, as basic constituents, 70% or more by weight of petroleum oils 
or of oils obtained from bituminous minerals. (HS 3403). Lubricants, industrial oils and 
related products (ICS 75.100).  
5. Title, number of pages and language(s) of the notified document: DUS 2045:2018 
Standard test met hod for determination of additive elements in lubricating oils by 
inductively coupled plasma atomic emission spectrometry, First Edition. (15 page(s), in 
English)   
6. Description of content: This Draft Uganda Standard covers the test method for the 
quanti tative determination of barium, boron, calcium, copper, magnesium, molybdenum, 
phosphorus, sulfur, and zinc in unused lubricating oils and additive packages.   
The precision statements are valid for dilutions in which the mass % sample in solvent is 
held co nstant in the range of 1 to 5 mass % oil. The precision tables define the 
concentration ranges covered in the interlaboratory study. However, both lower and 
higher concentrations can be determined by this test method. The low concentration limits 
are depen dent on the sensitivity of the ICP instrument and the dilution factor. The high 
concentration limits are determined by the product of the maximum concentration defined 
by the linear calibration curve and the sample dilution factor.   
Sulfur  can be determined if the instrument can operate at a wavelength of 180 nm. The 
values stated in SI units are to be regarded as standard. No other units of measurement 
are included in this standard.  
7. Objective and rationale, including the nature of urgent problems where 
applicable: Prevention of deceptive practices and consumer protection; Harmonization  G/TBT/N/UGA/940
