GOST 31967-2012 PDF

Full title and description

GOST 31967-2012 — Internal combustion reciprocating engines. Emissions of harmful substances with the exhaust gases. Limit values and test methods. Specifies limit values and standardized methods for determining gaseous emissions from piston internal combustion engines (marine, locomotive and industrial diesel engines) during bench testing; does not apply to automotive, tractor or aircraft engines.

Abstract

This standard establishes permitted concentrations and specific mass emissions (for example, g/kW·h) of key gaseous pollutants (carbon monoxide, nitrogen oxides, hydrocarbons and related species) from piston internal combustion engines under bench-test conditions, and describes required measurement procedures, correction factors and test conditions to ensure repeatable, comparable results. It also defines application of engine family/group concepts for production testing.

• Edition / version: GOST 31967-2012 (original 2012 edition); includes amendment(s) — Amendment No.1 entered by Rosstandart order dated 20 March 2018.
• Number of pages: ≈31 pages (typical published copy).

Scope

Applies to measurement and normalization of gaseous pollutant emissions from new and overhauled piston internal combustion diesel engines during bench (test‑stand) trials for marine, locomotive (diesel‑traction) and industrial applications. The standard sets test conditions, sampling and analytical procedures, calculation rules (including atmospheric and fuel composition correction factors) and application of family/group testing approaches; explicitly excludes automotive, tractor and aircraft engines.

Key topics and requirements

• Scope of application: marine, locomotive and industrial piston diesel engines; exclusions for automotive, tractor and aircraft engines.
• Pollutants covered: carbon monoxide (CO), nitrogen oxides (NOx), total hydrocarbons (HC) and related parameters expressed as mass per unit energy (e.g., g/kW·h).
• Test methods: bench/stand testing procedures, sampling locations (typically downstream of turbine/exhaust system where applicable), analytical techniques and calibration requirements.
• Correction and calculation: atmospheric factor, fuel composition factor and regime correction coefficients used to convert measured concentrations to standardized emission values.
• Use of family/group concepts: rules for applying results from a representative engine to a family or group of similar engines in series production.
• Reference to related test/acceptance standards: e.g., requirements link to GOST 10448 (engine acceptance and test methods) and to occupational/safety and reporting norms.

Typical use and users

Used by engine manufacturers, test laboratories, shipyards, locomotive builders, industrial engine users, certification bodies and regulatory agencies to verify compliance with emission limits during type‑approval, acceptance testing and post‑overhaul verification. Also used by environmental and emissions specialists for reporting and by design engineers to validate emission control measures.

Related standards
