Scope: This Technical Report addresses the specifications of natural gas as a compressed fuel for vehicles as an addendum to ISO 15403-1. Specifically, it is intended to satisfy requests for quantitative data. The following are critical items regarding gas composition: water content; sulfur compounds; particulate matter; higher hydrocarbons; CO2; free oxygen; glycol/methanol; oil content corrosive components; This Technical Report pertains only to compressed natural gas as it enters the fuel containers on the vehicle. It does not apply to the natural gas delivered to a refuelling station.
