ASTM D6823 Specification for Commercial Boiler Fuels with Used Lubricating Oils
4. Significance and Use
4.1 The intention of this specification is to cover fuel oil used in industrial equipment and commercial boilers as stated in the Scope section. The use of used lube oil in marine and industrial diesel engines is a contentious issue. A major marine fuel oil specification is ISO 8217. Fuel oils manufactured against this standard may also meet the requirements of ISO 8217 and can be used in marine diesel engine operations provided compliance to ISO 8217 is demonstrated.
