ASABE: American Society of Agricultural and Biological Engineers

ASABE, the American Society of Agricultural and Biological Engineers, is a nonprofit organization that develops and publishes standards for engineering applicable to agriculture, food and other biological systems. Headquartered in St. Joseph, United States, ASABE has over 9,000 members, representing over 100 countries. Heavily involved in publishing, ASABE publishes journals and textbooks in addition to ASABE standards. ASABE also serves as the administrator for the U.S. TAGs (United States Technical Advisory Group) to ISO/TCs 23, 234 and 238 (International Organization for Standardization/Technical Committee) and to many of the subcommittees for ISO/TC 23. Standards from ASABE are available both individually, directly through the ANSI webstore, and as part of a Standards Subscription. If you or your organization are interested in easy, managed, online access to standards that can be shared, a Standards Subscription may be what you need - please contact us at: or 1-212-642-4980 or Request Proposal Price.

Below are ASABE's best-selling standards. To find additional standards, please use the search bar above.

ANSI/ASAE EP433 DEC1988 (R2015) W/Corr. 1

Loads exerted by Free-Flowing Grain on Bins

This Engineering Practice presents methods of estimating the grain pressures within centrally loaded and unloaded bins used to store free-flowing, agricultural whole grain. Includes Corrigendum 1.

ASABE/ISO 27850:2013 MAY2016

Tractors for agriculture and forestry - Falling object protective structures - Test procedures and performance requirements.

Sets forth the test procedure and performance requirements for a falling object protective structure, in the event such a structure is installed on an agricultural or forestry tractor.


Quantities and Units of Electromagnetic Radiation for Plants (Photosynthetic Organisms)

This document provides definitions and descriptions of metrics used for radiation measurements for plant (photosynthetic organisms) growth and development.

ANSI/ASAE S276.8 APR2016

Slow Moving Vehicle Identification Emblem (SMV Emblem).

Establishes specifications that define a unique identification emblem, the Slow Moving Vehicle Emblem (SMV Emblem), to be used only for slow moving machines (vehicles), when operated or traveling on public roads.


Diaphragm Design of Metal-Clad, Wood-Frame Rectangular Buildings

This Engineering Practice is a consensus document for the analysis and design of metal-clad woodframe buildings using roof and ceiling diaphragms, alone or in combination. The roof (and ceiling) diaphragms, endwalls, intermediate shearwalls, and building frames are the main structural elements of a structural system used to efficiently resist the design lateral (wind, seismic) loads.

ANSI/ASAE S338.5 MAY2006 (R2016)

Field Equipment for Agriculture-Safety Chain for Towed Equipment

This Standard covers the specifications for an auxiliary attaching system to retain a connection between towing and towed agricultural field equipment in the event of separation of the primary attaching system long enough to bring the machines to a stop. It should not be construed that this auxiliary system can ensure that control or connection will be maintained in the event of incidents such as loss of control, rollover, jackknife, or collision.

This Standard applies to all combinations of towing and towed agricultural field equipment when traveling on highways. Requirements for braking of towed equipment and recommendations for maximum travel speeds are given in ASAE S365.6.

ANSI/ASAE S365.9 NOV2011 (R2017)

Braking System Test Procedures and Braking Performance Criteria for Agricultural Field Equipment

The purpose of this Standard is to establish requirements, minimum performance criteria, and performance test procedures for braking systems on agricultural field equipment. 

ASAE D384.2 MAR2005 (R2014)

Manure Production and Characteristics

This standard provides three types of information for estimating characteristics of livestock and poultry manure: Typical characteristics for manure ææas-excretedÆÆ by livestock and poultry based on typical diets and animal performance levels in 2002 (Section 3); Equations for estimating manure excretion characteristics based on animal performance and dietary feed and nutrient intake specific to an individual situation (Sections 4 through 9);Typical characteristics for manure ææas-removedÆÆ from manure storage or animal housing (Section 10).

ASAE EP562.1 SEP2015

Procedure for Determining Recommended Ballast and Minimum Rear Wheel Tread Settings for Agricultural Tractors with Agricultural Front Loaders

This engineering practice is intended as a guide to determine the minimum ballast and tread settings recommended for operation of an agricultural front loader mounted on a two-wheel drive tractor or a two-wheel drive tractor with front assist as defined in section and of ASAE S390.5. These ballast and tread setting recommendations are intended to reduce the risk of vehicle overturn in typical operation.


As the voice of the U.S. standards and conformity assessment system, the American National Standards Institute (ANSI) empowers its members and constituents to strengthen the U.S. marketplace position in the global economy while helping to assure the safety and health of consumers and the protection of the environment.
