SAE J1939-73 Emissions Reporting is a standardized testing service that ensures the accurate measurement of exhaust emissions from vehicles. This testing service is governed by various international and national standards, which are outlined below:
ISO 14001:2015: Environmental Management Systems Provides guidelines for environmental management systems and their implementation
Covers aspects such as energy consumption, waste management, and pollution reduction
ASTM E2054-10: Standard Practice for Determining the Emissions from Cremators Using the Combustion Chamber Method Specifies a procedure for measuring emissions from cremators using the combustion chamber method
Includes requirements for sampling, analysis, and reporting
EN 15882:2012: Exhaust gas analysis - Measurement of carbon monoxide (CO) and carbon dioxide (CO2) Describes methods for measuring CO and CO2 in exhaust gases
Covers aspects such as sampling, analysis, and calibration
TSE EN ISO 9001:2008: Quality Management Systems Specifies requirements for quality management systems
Covers aspects such as leadership, planning, execution, and control
The standard development organizations (SDOs) responsible for these standards include:
International Organization for Standardization (ISO): Develops and publishes international standardsAmerican Society for Testing and Materials (ASTM): Develops and publishes technical specifications and standardsEuropean Committee for Standardization (CEN): Develops and publishes European standardsStandards evolve and get updated as new technologies emerge, and testing methods are refined. The development process involves:
1. Research: Identifying areas where improvements can be made
2. Drafting: Writing the standard based on research findings
3. Review: Revising the standard based on feedback from stakeholders
4. Publication: Publishing the final standard
The specific standards that apply to SAE J1939-73 Emissions Reporting testing are:
SAE J1939-73:2018: On-Board Diagnostics (OBD) Regulation - Emissions Reporting Specifies requirements for emissions reporting in OBD systems
Covers aspects such as data formats, sampling rates, and analysis procedures
ISO 8178-1:2014: Reciprocating internal combustion engines - Measurement of emission of gaseous pollutants Describes methods for measuring CO, CO2, NOx, HC, and particulate matter emissions
