Sulfur test methods have always been important for compliance with mandated fuel sulfur regulations. It is very challenging to accurately and precisely quantify fuel sulfur at these levels.
Techniques for fuel sulfur include wet chemistry, X-ray fluorescence, atomic spectroscopy and various thermal combustion methods with different detection techniques such as microcoulometry, UV-fluorescence, and electrochemistry. Table 1 outlines some of the more common test methods used to quantify sulfur in middle distillate fuels. Also shown is the range of sulfur concentrations and ASTM D diesel fuel grades they are applicable to. This test method was later found to be inadequate because it was originally developed for aromatic hydrocarbons and not petroleum products and its precision did not conform to the statistical protocols used for petroleum products D was later revised with new precision data and issued separately as D After legal action, EPA changed the test method requirements in Instead of requiring a specific test method, a performance based criteria was adopted.
Any test method can qualify as an EPA approved test method provided it meets the minimum performance requirements outlined in 40 CFR In order for a test method to qualify for EPA approval, each test facility seeking approval must show that the precision and accuracy of their test facility meets EPA requirements.
Abstract : Sulfur test methods are important for compliance with mandated fuel sulfur regulations. Measurement techniques for fuel sulfur include wet chemistry, X-ray fluorescence, atomic spectroscopy and various thermal combustion methods.
Fuel Property Testing: Sulfur
You may be required to comply with this standard if you intend to undertake an oil recycling operation. You may be entitled to a product stewardship oil benefit for the sale or consumption of recycled oil that you have recycled in Australia. To be eligible you must be registered for entitlement to product stewardship oil benefits. This standard details the general bomb test method for determination of the amount of sulfur in lubricating oils with additives, additive concentrates, lubricating greases, and other petroleum products with low volatilities.
ASTM D 129:2018
Historical Version s - view previous versions of standard. More D This standard details the general bomb test method for determination of the amount of sulfur in lubricating oils with additives, additive concentrates, lubricating greases, and other petroleum products with low volatilities. This test method entails oxidizing samples by combustion in a bomb containing oxygen under pressure. The amount of sulfur is determined by gravimetry. Materials needed for the test include a combustion bomb, sample cup, firing wire, ignition circuit, and a cotton wicking or nylon sewing thread. All reagents, samples, and other chemicals used for the test should conform to the required concentration and purity.
