This SAE Standard sets forth the procedures to be used in measuring sound levels and determining the time weighted sound level at the operator's station(s) of specified off-road self-propelled work machines. This document applies to the following work machines which have operator stations as specified in SAE J1116: • Crawler Loader • Grader • Log Skidder • Wheel Loader • Crawler Tractor with Dozer • Pipelayer • Dumper • Wheel Tractor with Dozer • Trencher • Tractor Scraper • Backhoe • Sweeper • Roller/Compactor • Hydraulic Excavator • Pad Foot Wheel Compactor with Dozer • Excavator and Wheel Feller-Buncher The instrumentation requirements and specific work cycles for these machines are described. The method used to calculate the time weighted average sound level at the operator station(s) is specified for Leq(5), or optional exchange rates, during continuous operation in a work cycle representing continuous medium to heavy work. The work cycles provide a repeatable reproduceable means
Through the use of ultra-high frequency ultrasound, typically above 10 MHz, Acoustic Microscopy (AM) non-destructively finds and characterizes physical features and latent defects (visualization of interior features in a layer by layer process) - such as material continuity and discontinuities, sub-surface flaws, cracks, voids, delaminations and porosity. AM observed features and defects can be indicators that the components were improperly handled, stored, altered or previously used. If AS6171/6 is invoked in the contract, the base document, AS6171 General Requirements shall also apply.
The recommended practice describes a design standard that defines the maximum recommended voltage drop of the starting motor main circuits, as well as control system circuits, for 12/24-V starter systems. The battery technologies used in developing this document include the flooded lead acid, gel cell, and AGM. Starting systems supported by NiCd, Lithium Ion, NiZn, etc., or Ultracaps are not included in this document. This document is not intended to be updated or modified to include starter motors rated at voltages above the nominal 24-V electrical system. The starter is basically an electrical-to-mechanical power converter. If you double the available battery power in, you double the peak mechanical power out and double the heat losses. This means that we have to pay special attention to how battery power changes when we change the battery voltage and the effects it may have in overpowering the cranking system. A new stand-alone document would need to be developed to address
The following system of symbols is recommended for use in technical papers and engineering reports dealing with hydrodynamic drives.
This SAE Recommended Practice identifies graphic symbols used in electrical circuit diagrams. The symbols aid troubleshooting electrical systems.
This SAE Aerospace Recommended Practice (ARP) describes the continuous sampling and analysis of gaseous emissions from aircraft gas turbine engines. The measured gas species include carbon monoxide (CO), carbon dioxide (CO2), nitric oxide (NO), nitrogen dioxide (NO2), hydrocarbons (HC), and water vapor (H2O). This ARP excludes engine operating procedures and test modes, and is not intended for in-flight testing, nor does it apply to engines operating in the afterburning mode. It is recognized that there will probably be major advances in the gas analysis measurement technology. It is not the intent of this ARP to exclude other analysis techniques, but to form the basis of the minimum amount of conventional instruments (those in common industry usage over the last fifteen years) required for the analysis of aircraft engine exhaust. It is the responsibility of the analyst to demonstrate the alternative measurement technology has comparable (or better) performance than the techniques

This standard defines uniform quality and technical requirements relative to metallic parts marking performed using "data matrix symbology" within the aviation, space, and defense industry. ISO/IEC 16022 specifies general requirements (e.g., data character encodation, error correction rules, decoding algorithm). In addition to ISO/IEC 16022 specification, part identification with such symbology is subject to the requirements in this standard to ensure electronic reading of the symbol. The marking processes covered by this standard are as follows: Dot Peening Laser Electro-Chemical Etching Further marking processes will be included, if required. Unless specified otherwise in the contractual business relationship, the company responsible for the design of the part shall determine the location of the data matrix marking. Symbol position should allow optimum illumination from all sides for readability. This standard does not specify information to be encoded.
This document describes an assessment of the effectiveness of a specified test plan used to screen for counterfeit parts. The assessment includes the determination of the types of defects detected using a specified test plan along with the related counterfeit type coverage. The output of this evaluation will produce Counterfeit Defect Coverage (CDC), Counterfeit Type Coverage (CTC), Not-Covered Defects (NCDs), and Under-Covered Defects (UCDs). This information will be supplied to the test laboratory’s customer in both the test report and the Certificate of Quality Conformance (CoQC). This evaluation method does not address the effectiveness of detecting tampered type devices. The Test Evaluation Method also describes an Optimized Test Sequence Selection, in which a test sequence is selected that maximizes the CDC utilizing test cost and time as constraints, for any tier level except the Critical Risk Level. The constraints can be adjusted until the desired CDC is achieved. The output
