This SAE Information Report applies to liquefied natural gas used as vehicle fuel and requires LNG producers to provide the required information on the fuel composition and its "dispense by" date.

The purpose of this document is to provide the fixed assumption and calculation so that LNG producers can provide the require product information data which fuel composition and it's "dispense by" dates can be calculated. The "dispense by" date provides users the date when the fuel no longer meets the minimum hydrocarbon requirement of CARB, which may compromise the engine emission performance, warranty or reliability. The "dispense by" date provides users the time/date when the fuel meets the minimum hydrocarbon requirement of CARB. Beyond this date/time the fuel composition may compromise engine emission performance, warranty or reliability.
