This SAE Standard describes a method for determining the exterior noise emitted by earthmoving machinery in terms of the A-weighted sound power level while the machine is in a stationary test condition. At six positions on a hemispherical surface, the equivalent continuous A-weighted sound pressure levels are measured. The A-weighted sound power level of the machinery is calculated from the measured values.

This SAE Standard describes a method for measuring the weighted sound pressure levels at prescribed microphone positions in the proximity of a device or machine for outdoor use, in order to determine compliance with noise limits. The A-weighted sound power level of the source is calculated from the measured values.

This SAE Standard describes a method for determining the noise emitted by earthmoving machinery at the operator's position in terms of the equivalent continuous A-weighted sound pressure level while the machine is in a stationary test condition.

This SAE Standard describes a method for determining the noise emitted to the environment by earthmoving machinery in terms of the A-weighted sound power level while the machine is working under dynamic test conditions.

This SAE Standard describes a method for determining the noise emitted by earthmoving machinery at the operator’s position in terms of the equivalent continuous A-weighted sound pressure level while the machine is carrying out a simulated work cycle.

The purpose of this SAE Standard is to define test conditions, describe tests to be made, specify data to be obtained, show formulas and calculations, define terms, and establish a uniform method of reporting so that performance data obtained on various makes and models of tractors, tested in accordance with this document, will be comparable regardless of where the tests are made. Because of the availability of many tractor models and types that can be equipped with a variety of special or optional equipment, the scope of this document must be limited to obtaining and reporting only the most significant of widely used performance data. Tests performed to either the Standard Code as outlined in Section 5 or the Restricted Code as outlined in Section 6 will satisfy requirements of this Agricultural Tractor Test Code. This document is technically equivalent to the OECD Tractor Test Code C(87)53, Annex I and Annex II.

The scope of this SAE Standard is the definition of the functional, environmental, and life cycle test requirements for electrically operated backup alarm devices primarily intended for use on off-road, self-propelled work machines as defined by SAE J1116 JUN86 (limited to categories of 1) construction, and 2) general purpose industrial).

This SAE Information Report provides information on certain fuels that are being used or have been suggested as alternatives to motor gasoline (SAE J312) or automotive diesel fuel (SAE J313) for use in spark-ignition or compression-ignition engines. Some of these fuels are derived from petroleum while others are from nonpetroleum sources.

This SAE Standard gives the specifications and dimensions for the assembly and clearances common to hydraulically-operated cylinders and to trailing-type farm implements. The specifications given permit the interchangeability of hydraulic operation between tractors equipped with a cylinder and trailing-type implements designed for this purpose, the tractor possessing enough power at its drawbar to operate the implement; and the transference of the hydraulic cylinder from one implement to another. This document applies to three categories of agricultural tractors, as follows in Table 1:
