GB 15097-2016

GB 15097-2016 specifies the emission limits and measurement methods for exhaust pollutants from marine engines, covering both the China Phase I and Phase II regulatory stages. It applies to the type approval, production consistency, and in-use compliance testing of engines installed on inland waterway vessels, coastal ships, and fishing boats operating in Chinese waters. This standard is enforced by Chinese maritime and environmental authorities to control nitrogen oxides, hydrocarbons, carbon monoxide, and particulate matter emissions from marine propulsion and auxiliary engines.
