ULSD Ultra Low Sulfur Diesel Testing

Ultra low sulfur diesel fuel (ULSD) testing.

Ultra low sulfur diesel testing by Intertek is accepted by the US EPA to perform sulfur determination of Ultra Low Sulfur Diesel (ULSD). Intertek operates the largest network of laboratories qualified to perform EPA qualified low sulfur analysis in the USA and Canada.

Diesel fuel sampling and mailing kits make it easy to ship diesel fuel samples directly to the nearest EPA qualified laboratory for rapid test results.

Ultra Low Sulfur Diesel / ULSD test methods:

• ASTM D5453: Total Sulfur in Light Hydrocarbons, Motor Fuels, and Oils
• ASTM D3120: Trace Sulfur in Light Liquid Petroleum Hydrocarbons
• ASTM D6079: Diesel Fuel Lubricity by the High Frequency Reciprocating Rig (HFRR)
• ASTM D2622: Sulfur in Petroleum Products by XRF
• ASTM D7039: Sulfur in Gasoline, Diesel Fuel by XRF
• ASTM D2624: Electrical Conductivity of Aviation and Distillate Fuels

Intertek USA and Canada laboratories are standardized to maximize analytical precision. The EPA approval process requires analytical methods meet accuracy and precision criteria in order to be accepted.

Ultra Low Sulfur Diesel:
Sulfur (Sulphur) in diesel fuel has been lowered to enable new pollution-control technology. The EPA requires a 97 percent reduction in the sulfur content of highway diesel fuel from 500 ppm to 15 ppm. ULSD fuel requirements became effective in 2006.

Sulfur Analysis and ULSD:
Under the EPA performance-based test method approach adopted in the diesel sulfur rule, multiple sulfur test methods are allowed. Methods qualify for approval provided they meet specified performance criteria under the Performance Based Testing Criteria in 40 CFR 80.584. Reference 40 CFR 80.584 and CFR 80.585.
