This SAE Standard establishes the requirements for lubricating oils containing ashless dispersant additives to be used in four-stroke cycle, reciprocating piston aircraft engines. This document covers the same lubricating oil requirements as the former military specification MIL-L-22851. Users should consult their airframe or engine manufacturers manuals for the latest listing of acceptable lubricants.
This SAE Information Report summarizes the characteristics of carburized steels and factors involved in controlling hardness, microstructure, and residual stress. Methods of determining case hardenability are reviewed, as well as methods to test for freedom from non-martensitic structures in the carburized case. Factors influencing case hardenability are also reviewed. Methods of predicting case hardenability are included, with examples of calculations for several standard carburizing steels. A bibliography is included in 2.2. The references provide more detailed information on the topics discussed in this document.
This SAE Standard applies to horizontal earthboring machines of the following types: a. Auger Boring Machines b. Rod Pushers c. Rotary Rod Machines d. Impact Machines e. Directional Boring/Drilling Machines The illustrations used are for classification and are not intended to resemble a particular machine. Only basic working dimensions are given. They may be supplemented by the machine manufacturer. This document is based on existing commercial horizontal earthboring machines. This document does not apply to specialized mining machinery in SAE J1116, conveyors, tunnel boring machines, pipe jacking systems, and microtunnelers.
This SAE Standard covers minimum requirements for soft (061) annealed seamless copper tube intended for automotive and general purposes. (Comparable specifications are ASTM B 75. Other copper tube is covered in SAE J463.) The tube shall be cold drawn to size and after forming shall be annealed in such a manner as to produce a finished product which will meet all requirements of this standard.
The purpose of this SAE Recommended Practice is to provide standardized dimensions for mounting starting motors. (See Figures 1 through 4.) It is recommended that a full register diameter having a minimum depth of 2.54 mm (0.100 in) be provided in the flywheel housing to insure proper control of gear center distance and clearance between pitch diameters. The clearance between the starting motor pilot diameter and the register diameter in the flywheel housing should be 0.03 mm (0.001 in) minimum to 0.25 mm (0.010 in) maximum. Text noted with an asterisk in Figures 1, 2, and 3, should not exceed root radius of pinion in order to provide clearance for the flywheel. The face of the starting motor mounting flange should be relieved at its junction with the pilot diameter to avoid mounting interference with flywheel housing. For backlash allowance between the pinion and ring gear refer to SAE J543. Dimensional units—millimeter (inch)
This SAE Information Report reviews the various physical and chemical properties of engine oils and provides references to test methods and standards used to measure these properties. It also includes general references on the subject of engine oils, base stocks, and additives.
The SAE Standard covers normalized electric-resistance welded flash-controlled single-wall, low-carbon steel pressure tubing intended for use as pressure lines and in other applications requiring tubing of a quality suitable for bending, double flaring, beading, forming, and brazing. Material produced to this specification is not intended to be used for single flare applications due to the potential leak path that would be caused by the ID weld bead. This specification also covers SAE J356 Type-A tubing. The mechanical properties and performance requirements of standard SAE J356 and SAE J356 Type-A are the same. Therefore, the designated differences of Type-A tubing are not meant to imply that Type-A tubing is in anyway inferior to standard SAE J356. The Type-A designation is only meant to address the unique manufacturing differences of the small diameter, light wall sizes (typically 15.88 mm OD x 1.24 mm wall and smaller.)
This SAE Recommended Practice includes the types of mounting configurations and the names of major components and parts peculiar to this type of machine. Illustrations used here are not intended to include all existing commercial machines or to be exactly descriptive of any particular machine. They have been provided to describe the principles to be used in applying this document.
The terms included in this SAE Information Report have been collected during the development of SAE documents related to standards for the adaptation of vehicles for use by persons with physical disabilities. It includes only those terms that are pertinent to the adaptive devices discipline, leaving to other authorities more common automotive engineering terms. Where several terms have a common meaning in the practice, the Terminology Task Force has attempted to select the most appropriate term. The Terminology Task Force recognizes that there will be a need to expand and update current terminology as advances in the industry occur, and as related standards documents are completed. Accordingly, they will continue to develop and maintain this document to reflect those changes.
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. This SAE standard is a special test code for specific types of earthmoving machinery. It is an extension of ISO 6081 which contains the general requirements for many types of machinery and equipment. A simulated rather than an actual work cycle test condition is chosen. Simulated work cycles provide acceptable noise emission data which are repeatable and representative. Actual work cycle tests are complex and repeatability can be a problem. Specific procedures are described in this document to enable the sound pressure level at the operator's position,with the machine in a simulated work cycle test condition, to be determined in a manner which is repeatable.
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 is special test code for specific types of earthmoving machinery. It is an extension of SAE J2101/ISO 4872, which contains the general requirements for construction equipment. A simulated dynamic rath than an actual work cycle test condition is chosen. Dynamic test conditions provide acceptable noise emission data, which are repeatable and representative. Actual work cycle tests are complex and repeatability can be a problem Specific procedures are described in this document to enable the sound power emission in dynamic test conditions to be determined in a manner that is repeatable.
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 is a special test code for specific types of earthmoving machinery. It is an extension of ISO 6081 which contains the general requirements for many types of machinery and equipment. Specific requirements are provided in this special test code to enable the sound pressure level at the operator's position, with the machine in a stationary test condition, to be determined in a manner which is repeatable. Attachments (bucket, dozer, etc.) for the manufacturer's production version shall be fitted since this is the configuration most likely to exist when the machine is in actual use. This document will enable compliance with noise limits to be determined.
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. NOTES: 1. When nine or more microphone positions are prescribed in the proximity of the source (as in Section 7), the A-weighted sound power levels determined in accordance with this document tend to result in standard deviations less than approximately 2 dB, provided that the spectrum does not contain pronounced discrete frequencies; if it does, the magnitude of the uncertainties will be larger and no general rules for the magnitude of the uncertainties can be given.
