Criteria catalog for additives in fuel oil

According to DIN 51603-1, DIN SPEC 51603-6 and DIN/TS 51603-8, the use of additives is permitted under certain conditions to improve/ensure the quality of heating oil. DGMK had last documented in 2017 in DGMK Research Report 646-2 test criteria for additives that can be used in heating oil EL, standard, heating oil EL, low sulfur or heating oil EL A Bio. In the present report 646-3, an extension is made for the use of additives in paraffinic heating oils according to DIN/TS 51603-8. Compliance with the stated specifications is intended to exclude, as far as possible, undesirable side effects of additives when used in fuel oils. For these minimum test criteria, test methods were selected and examined by laboratories for differentiation capability and manageability. In view of the fact that some test methods cannot be used to evaluate all fuel oil qualities, the minimum test criteria defined vary depending on the fuel oil quality: 6 minimum test criteria were defined for additives that are to be used in EL fuel oil in accordance with DIN 51603-1 or DIN/TS 51603-8. For additives to be used in heating oil EL A Bio according to DIN SPEC 51603-6, 5 minimum test criteria were recommended. The minimum test criteria defined in this report are primarily intended to provide assistance in the selection and application of additives.
