Exhaust systems remove unwanted gases, whether the gasses are toxic welding fumes or airborne grease. What are the industrial standards for exhaust systems?

ASTM Standards for Exhaust Systems

ASTM F1431 gives the standard specification for the water trap used with diesel exhaust systems. ASTM F1431 is ANSI approved.
ASTM D7821 is the standard field test method for determining how much urea is present in diesel exhaust fluid.
ASTM E1265 describes the standard test method for measuring the insertion loss when pneumatic exhaust silencers are used.


ISO Standards for Exhaust Systems

ISO 11042 is the standard for measuring the exhaust of gas turbines. ISO 11042 part 1 is for the measurement and evaluation of the gas emissions. ISO 11042 part 2 is the standard for automated emission monitoring.
ISO 7967 gives the standard for reciprocating internal combustion engines. ISO 7967 part 4 defines the standard vocabulary for the air/exhaust gas ducting systems in these engines. ISO 8178 describes how to measure the exhaust emissions.
ISO 16183 gives the transient test conditions and test methods for determining the emissions of raw exhaust gases using partial flow dilution systems.
ISO 29042 outlines the process for evaluating how well exhaust systems remove airborne hazardous substances.
ISO 16247 describes the helium test method used to detect exhaust system leaks.
ISO 23274 part 2 outlines the methods used to measure the fuel consumption and exhaust emissions of hybrid-electric vehicles.

SAE Exhaust System Standards

SAE J1492 outlines the process of measuring the sound level of light vehicle exhaust systems when stationary.
SAE J2515 lists the requirements for the high temperature materials used in exhaust manifolds.
SAE J1287 is the standard for measuring the sound pressure level for stationary motorcycles designed for use on the highway.
SAE J1711 describes the recommended method of measuring the exhaust from hybrid gas-electric vehicles.
SAE J2567 is the test procedure for measuring the exhaust sound level of a stationary snowmobile.
SAE J2914 gives the standard terminology for exhaust gas recirculation coolers and their uses.
SAE J335 is the standard for small engine exhaust system fire suppression systems. SAE J335 has been adopted by the Department of Defense but not by ANSI.
SAE J1207 is the procedure for measuring the effectiveness of silencers in reducing engine air intake and exhaust system noise. SAE J1207 is ANSI approved.
SAE J1088 describes the test procedure for measuring the gases in the exhaust of small utility engines. SAE J1088 is ANSI approved.
SAE ARP4056 gives the exhaust system design considerations for rotorcraft engines. This documentation is a recommendation and not a formal standard.

SAE ARP1179 is the exhaust smoke measurement method for aircraft gas turbines.

ANSI Standards for Exhaust Systems

ANSI International standards for exhaust systems come from a number of subsidiary organizations.

UL 710 gives the performance specifications for safety exhaust hoods used with commercial cooking equipment. UL 710 is ANSI approved. UL 1046 is the standard for safety grease filters used in exhaust ducts to prevent grease particles from coating the inside of the ducts and creating a fire hazard. UL 1046 is ANSI approved.
NFPA 91 is the standard for exhaust systems designed for moving noncombustible gases and mists. NFPA 91 was published in 2010 and is ANSI approved.
ASHRAE 149 is the ANSI approved standard for testing fans used in smoke management systems to exhaust smoke.
ASSE Z9.7 is the standard for re-circulating air from industrial process exhaust systems. ASSE Z9.7 was published in 2007 and is ANSI approved.
ASME PTC 19.10 lists the performance test codes used when running calculations involving different gaseous exhausts from stationary combustion sources. ASME PTC 19.10 is ANSI approved.

Military Specifications for Exhaust Systems

MIL-F-1754 was the naval standard for ventilation exhaust flame arrestors. First issued in 1962, this military standard is still active. MIL-I-2220 is the standard for gas monitoring instruments used on submarines.

For most other military applications for exhaust systems, industry standards like those by ANSI International and the ISO are used.

Federal Standards for Exhaust Systems

14 CFR PART 34 gives the exhaust emission requirements for turbine engine powered aircraft. There are also numerous Federal Aviation Administration or FAA standards for aircraft exhaust systems, both for civilian and military aircraft.
