ISO 18854:2015 specifies the measurement and evaluation methods for gaseous and particulate exhaust emissions from reciprocating internal combustion (RIC) engines under steady-state conditions on a test bed, necessary for determining one weighted value for each exhaust gas pollutant. Various combinations of engine load and speed reflect different engine applications. It is applicable to RIC marine engines intended to be installed in small craft up to 24 m length of hull.

Abstract

Overview

EN ISO 18854:2015 (ISO 18854:2015) specifies standardized test‑bed measurement methods for gaseous and particulate exhaust emissions from reciprocating internal combustion (RIC) engines used in small craft. The standard covers steady‑state engine testing on a dynamometer to determine a single weighted value for each exhaust pollutant across representative combinations of engine speed and load. It applies to marine RIC engines intended for small craft up to 24 m length of hull and is published by CEN as EN ISO 18854:2015.

Key topics and technical requirements

Scope and test conditions: steady‑state test cycles, engine air inlet/exhaust/cooling/lubrication system conditions and test validity requirements.
Engine family concept: guidance on selection of a parent engine and application of engine family principles.
Measurement of exhaust gas flow: multiple acceptable methods are referenced - direct measurement, air & fuel measurement, fuel flow and carbon‑balance, tracer methods, air flow / air‑to‑fuel ratio, and total dilute exhaust gas flow.
Gaseous emissions determination: analyser specifications, gas drying, sampling lines and analyser types (e.g., NDIR, HFID, GC where applicable).
Particulate determination: particulate sampling, filter media, weighing chamber and balance standards for gravimetric analysis.
Calibration and accuracy: calibration gases, span/zero checks, analyser warm‑up, leakage tests and overall accuracy requirements.
Test fuels: requirements for reference fuels used in petrol and diesel engine emission tests.
Data and reporting: procedures to calculate weighted pollutant values from steady‑state points and required measurement data.

Practical applications

Certification testing of marine engines for small craft (pleasure craft, workboats up to 24 m) where quantified gaseous and particulate emissions are required.
Engine development and optimization for emissions reduction (combustion tuning, aftertreatment evaluation).
Regulatory compliance testing where EN ISO 18854:2015 provides a harmonized method to generate comparable emission data.
Laboratory test-bed standardization to ensure repeatable, auditable emission measurements.

Who should use this standard

Marine engine manufacturers and test laboratories.
Small craft builders and certification bodies.
Emissions consultants and R&D engineers working on internal combustion marine powerplants.
Regulatory agencies referencing EU Directive 2013/53/EC (see Annex ZA relating this standard to essential requirements).

Related standards & compliance

EN ISO 18854:2015 is the CEN-adopted version of ISO 18854:2015 and includes Annex ZA linking test methods to EU Directive 2013/53/EC for recreational craft.
Users should reference relevant analyser, balance and fuel standards cited in the normative references of ISO 18854 for complete compliance.
