The choice of the type and grade of solder for any specific purpose depend on the materials to be joined and the method of applying. Those with higher amounts of tin usually wet and bond more readily and have a narrower semi-molten range than lower amounts of tin. For strictly economic reasons, it is recommended that the grade of solder metal be selected that contains least amount of tin required to give suitable flowing and adhesive qualities for application.
Powder metal (P/M) parts are manufactured by pressing metal powders to the required shape in a precision die and sintering to produce metallurgical bonds between the particles, thus generating the appropriate mechanical properties. The shape and mechanical properties of the part may be subsequently modified by repressing or by conventional methods such as machining and/or heat treating. While powder metallurgy embraces a number of fields wherein metal powders may be used as raw materials, this standard is concerned primarily with information relating to mechanical components and bearings produced from iron-base materials.

This SAE Standard provides manufacturers/marketers, testing facilities and providers of technician training with a procedure for certifying compliance with the applicable standard. Manufacturers/marketers or sellers who advertise their products as Certified to an SAE J standard shall follow this procedure. Certification of a product is voluntary; however, this certification process is mandatory for those advertising meeting SAE Standard(s) requirements. Only certifying to this standard allows those claiming compliance to advertise that their product (unit), component, or service technician training meets all requirements of the applicable SAE standard. Certification of compliance to this and the appropriate standard and use of the SAE label on the product shall only be permitted after all the required information has been submitted to SAE International and it has been posted on the SAE web site.
The SAE Driving Skills Certification Criteria establishes skill levels to drive motorized vehicles in various configurations and environments. It includes the certification criteria required for a driver to demonstrate proficiency along with the facility and examiner requirements to accurately confirm a driver's performance.
The main purpose of this Recommended Practice is to verify that vehicles are capable of communicating a minimum subset of information, in accordance with the diagnostic test services specified in SAE J1979: E/E Diagnostic Test Modes, or the equivalent document ISO 15031-5: Communication Between Vehicle and External Equipment for Emissions-Related Diagnostics – Part 5: Emissions-related diagnostic services. Any software meeting these specifications will utilize the vehicle interface that is defined in SAE J2534, Recommended Practice for Pass-Thru Vehicle Programming.
This SAE Information Report is provided as an advisory guide. Individual application discretion is recommended. The content has been presented as accurately as possible, but responsibility for its application lies with the user. The document covers a number of the variables in the torque-tension relationship: friction, materials, temperature, humidity, fastener and mating part finishes, surfaces, and the kind of tightening tools or equipment used. Also described in this document is the torque management required to achieve satisfactory fastened joint tightening. This guide is limited in application to clearance fit threads, such as the common 6g/6H class of fit. Other thread types including interference fit, mechanical locking, prevailing torque, or forms other than ISO-Metric may apply to some aspects of this standard but are not specifically covered.
The CRABI dummy was developed to evaluate small child restraint systems in automotive crash environments, in all directions of impact, with or without air bag interaction Basic anthropometry for this test device was taken from the University of Michigan Transportation Research Institute Report 85-23. Weight distribution and scaling methods for the infant were approved by the Society of Automotive (SAE) Infant Dummy Task Group. The dummy weighs 17.2 pounds and has a 26.4 inches standing or 17.3 inches sitting height. The Hybrid Ill-like neck and lumbar spine are laterally notched to reduce lateral stiffness The shoulders have flesh support for durability and human-like performance in areas where seatbelt webbing may be placed. In addition, rubber elements are used in each joint to improve biofidelity and to give the CRABI infant-like range of motion. The CRABI Six-Month-Old design meets all the SAE Infant Dummy Task Group anthropometry, biomechanical and instrumentation requirements.
This SAE Standard establishes test methods for the evaluation of devices and equipment in vehicles against transient transmission by coupling via lines other than the power supply lines. The test methods demonstrates the immunity of the instrument, device, or equipment to coupled fast transient disturbances, such as those caused by switching of inductive loads, relay contact bouncing, etc. Four test methods are presented in SAE J1113-12: the capacitive coupling clamp (CCC) method the direct capacitive coupling (DCC) method the inductive coupling clamp (ICC) method the capacitive/inductive coupling (CIC) method
This SAE Recommended Practice specifies measurement procedures and performance levels for magnetic and electric field emissions and conducted power mains emissions over the frequency range 150 kHz to 30 MHz, for vehicles incorporating electric propulsion systems, e.g., battery, hybrid, or plug-in hybrid electric vehicles. Conducted emission measurements in this document are applicable only to battery-charging systems which utilize a switching frequency above 9 kHz, are mounted on the vehicle, and whose power is transferred by metallic conductors. Conducted emission requirements apply only during charging of the batteries from AC power lines. Conducted and radiated emissions measurements of battery-charging systems that use an induction power coupling device are not covered by this document. The measurement of electromagnetic disturbances for frequencies from 30 MHz to 1000 MHz is covered in CISPR 12.
This new document, at a minimum a recommended practice, will use as a basis the existing SAE J2945/1 to a version that uses LTE V2X (Long Term Evolution Vehicle to X) as specified in 3GPP (3rd Generation Partnership Project) R-14 as the radio access technology and on-board vehicle-to-vehicle (V2V) safety communications system for light vehicles. This new document addresses the on-board system needs for ensuring that the exchange of BSMs (Basic Safety Messages) in V2V safety communications provides the desired interoperability and data integrity to support the performance of the envisioned safety applications. Specifically, this new document will include standards profiles, functional requirements, and performance requirements.
This SAE Standard details procedures for testing lead-acid SLI (starting, lighting, and ignition), Heavy-Duty, EV (electric vehicle) and RV (recreational vehicle) batteries to determine the effectiveness of the battery venting system to retard the propagation of an externally ignited flame of battery gas into the interior of the battery where an explosive mixture can be present. NOTE: At this time 2011, there is no known comparable ISO Standard.
This standard is intended to provide a method (or methods) to obtain repeatable and consistent measurements to reflect true engine performance and durability in customer. Standardized methodology is needed to normalize engine performance to fairly rate engine operating variables and parameters. Operational protocols will be defined according to engine class and will be based on those developed for on-highway applications. Based on typical engine operation, a series of speed and load combinations and/or sequences will be determined. The scope will include dynamometer based testing and static propeller-based experiments. The industry consists of many platforms that use reciprocating engines as the main (or sole) provider of rotational energy to propeller. There also exists a significant move towards hybrid-based engine-battery systems that are expected to have different operational requirements.
