NO. 1-D S500 | Diesel Fuel Oil Testing According to ASTM D975-21

ASTM D975-21, Standard Specification for Diesel Fuel Oils, defines and provides specifications for No. 1-D S500 fuel oil.

No. 1-D S500 is a low sulfur light middle distillate fuel used in diesel engine applications that require higher volatility than No. 2-D S500 with a maximum of 500 ppm sulfur allowed.

Paragon is capable of performing a majority of the analysis related to the testing of No. 1-D S500 fuel oil according to ASTM D975-21 Table 1 requirements.

Procedures included on our A2LA Scope of Accreditation to ISO/IEC 17025:2005 are designated as such.

[A] ASTM D2622 is specified in 40 CFR Part 80 and is listed in ASTM D975-21 as the referee method for sulfur analysis on S500 grades. If your testing needs are not governed by 40 CFR Part 80, ASTM D5453 can be used as an alternative test procedure. Section 5.1.8 of ASTM D975-21 states that ASTM D5453 is appropriate for all grades of diesel fuel oil. Paragon currently offers analysis by ASTM D5453.
