ANSI B71.10:2018 pdf download.Off- Road Ground-Supported Outdoor Power Equipment一Gasoline Fuel Systems – Performance Specifications and Test Procedures.
ANSI B71.10 describes safety specifications and test procedures applicable to the gasoline fuel systems for off-road ground-supported outdoor power equipment with spark ignition engines of less than one liter displacement. Off-road ground-supported outdoor power equipment for which this standard may apply include walk-behind and riding lawn-mowers, snow throwers, powered log-splitters, shredders/grinders and tillers. The effective implementation date of ANSI B71.10 shall be two (2) years after the publication date and shall apply to all products built after that date. Manufacturers may also comply with the requirements of ANSI B71.10 anytime after the publication date.
NOTE — The tests described in this standard involve the use of hazardous materials, operations, and equipment. ANSI B71.10 does not purport to address all of the safety problems associated with its use. It is the responsibility of the user of ANSI B71.10 to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
