The final approval date for Fuels and Lubricants technical reports is shown following the J-report number. This approval date is the date of final approval by the Fuels and Lubricants Division. It is effective immediately subsequent to divisional approval for newly issued Standards, Recommended Practices, and Information Reports, and also for revised Information Reports and the SAE J1146 Recommended Practice. In the case of revised or cancelled Standards or Recommended Practices (used to define product quality), an 18-month optional grace period exists before they become fully effective.
