Standby Power is regulated by NFPA 110. The latest 2022 version has published the following in regards to routine diesel fuel testing.
"Diesel fuel maintenance and regular testing should begin the day of installation and first fill to establish a benchmark guideline for future comparison. Diesel fuel should be monitored for water on the bottom and tested for degradation and contamination." It is recommended that the fuel should be tested at least annually using applicable ASTM standards OR the manufacturers recommendations. If a fuel is found to be out of spec then it should be tested every 90 days until the analysis is deemed acceptable.
