ASTM D129 - Sulfur in Petroleum Products (General High Pressure Decomposition Device Method)


We perform quality testing by ASTM D129, which uses a high pressure decomposition device to measure the sulfur content in oils and other petroleum products. ASTM D129 can be used for petroleum products such as lubricating oils with additives, additive concentrates, and some lubricating greases. The sample is placed in a high pressure decomposition device containing oxygen under pressure. The sample is then oxidized by combustion, and then the sulfur is determined by weight as barium sulfate. 

We also perform sulfur analysis by ASTM D2622ASTM D3227ASTM D4294ASTM D5623ASTM D5453ASTM D7039IP 61IP 342ISO 3012, and UOP 163. These different test methods use different instruments or procedures or are used for certain sample types. Click on the test method number to learn more about each test.
