What is ANSI/OPEI B71.10-2018?This is the newest edition of the ANSI and OPEI "Off-Road Ground-Supported Outdoor Power Equipment - Gasoline Fuel Systems - Performance Specifications and Test Procedures". This newest version of ANSI/OPEI B71.10 has a November 12th, 2020 implementation date. It applies to all relevant products built after that date.
Who should be interested in this?
- Outdoor Power Equipment (OPE) design engineers
- Manufacturers of small internal combustion engines
- OPE and OEM after-market parts manufacturers and suppliers
Who is ANSI?ANSI, the American National Standards Institute, is a private, not-for-profit organization that oversees the development of voluntary consensus standards for products, services, processes, systems and personnel in the United States. It also coordinates US standards with international standards so that American products can be sold worldwide.
Who is OPEI?OPEI, the Outdoor Power Equipment Institute, is an international trade association that represents power equipment, engine and utility vehicle manufacturers and suppliers. The OPEI developed the original B71.10 in 2008 and then revised it in November of 2018. The new standard goes into effect on November 12, 2020 (two years following the date the new standard was published by ANSI). OPEI is an ANSI accredited Standards Development Organization (SDO) and works with ANSI to develop industry standards.

What does ANSI/OPEI B71.10-2018 mean for fuel shut-off valves and fuel filters?The revised standard now includes new and updated structural integrity testing for inline fuel system components. One of the main goals of this new standard is to prevent the failure of these components.
These updated standards have added new fuel system component certification testing. This new testing was developed to mimic the stresses caused by in-use conditions. These stresses can cause part failures in fuel line components.
Component testing in the revised standards includes testing for fuel shut-off valves and plastic inline fuel filters. This testing covers both basic part integrity (leak testing) and the combinations of forces and exposure that can lead to stress cracking and potential fuel leaks.
ANSI product certification provides independent, third-party confirmation that products meet performance tests set by the relevant ANSI standard. This performance testing is performed by an ISO accredited testing laboratory. Accreditation ensures that testing laboratories have the necessary competency to correctly perform testing and certification.
ISO/IEC 17025 accredited testingISO 17025 is the ISO standard for accrediting independent testing laboratories. This accreditation is issued by ANAB, the ANSI National Accreditation Board. Accredited testing provides standardized, consistent, industry-wide processes to evaluate the performance and quality of critical component parts.

The ANSI/OPEI certification processSteps to ANSI/OPEI B71.10-2018 fuel shut-off valve and plastic fuel filter certification
- An ISO 17025 accredited independent testing laboratory is selected and contracted to do component testing to the relevant ANSI standard
- Supply the contracted testing laboratory with the required number of samples for each part being tested
- The testing laboratory tests all sample parts using the ANSI/OPEI testing methods and standards
- The testing laboratory reports the test results to the company that contracted for the component testing
- If all the component samples comply with the complete ANSI/OPEI performance requirements, then the parts are compliant with the ANSI/OPEI B71.10-2018 standard
The new ANSI/OPEI B71.10-2018 tests mimic the stresses caused by in-use conditions. The US Consumer Product Safety Commission notified ANSI and OPEI in 2015 that in-use stresses had led to part failures of fuel line components. Because of this, they recommended that additional testing standards be developed including testing standards for critical inline fuel components.
OPEI worked with ANSI to expand and develop these revised standards* and they were published on November 12th, 2018. The new standards come into force November 12th, 2020. Critical fuel line components added to the new testing standards include fuel shut-off valves and plastic inline fuel filters.
*This standard does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
Every sample part must pass every test for certification.
Tests performed*
- Leak testing
- Impact testing
- UV resistance testing
- Fuel resistance testing (E10)
- Fuel shut-off temperature testing
- Fuel shut-off actuation testing
*Each in-use simulation test is followed, in turn, by additional leak testing.
Why use original equipment fuel filters and valves?Using original equipment fuel filters and valves ensures replacement parts’ quality, durability and performance. OEM after-market fuel filters and valves from manufacturers with a proven reputation such as ITW Fastex Filtration and ITW Powertrain Components provide an additional assurance of quality and durability.
Adding certified performance testing to the new ANSI/OPEI B71.10-2018 standard now provides higher confidence in the products that are used in Outdoor Power Equipment and Outdoor Sports and Recreation.
