This SAE Recommended Practice describes a method to collect, identify, and quantify effluent resulting from deployment of in-vehicle stored energy restraint systems. Deployment and collection is completed in a 2.83 m3 (100 ft3 ) chamber. This procedure is written as a guideline for the identification and quantification of both particulate effluent (size, concentration, and composition) and gaseous effluent (concentration and composition). The intent of this procedure is to describe and recommend testing methods and not to establish limits for the effluent. This procedure should be used in conjunction with performance specifications from the customer and/or manufacturer of the device(s) being tested. This is a general procedure for repetitive and comparative testing, and suggests only general guidelines for the safe conduct of tests and reliable data correlation.

This SAE Information Report discusses the significant factors which measure the effectiveness of the total occupant restraint system in commonly encountered collision configurations. The total system includes the components which affect occupant injury by influencing the manner in which the collision energy management is accomplished. In addition to the elements that contribute to impact attenuation, consideration must be given to factors that encourage maximum use, such as comfort, reliability, appearance, and convenience. Hence, system evaluation necessarily involves consideration of the complete vehicle.
Occupant Protection and Biomechanics Steering Committee
This SAE Recommended Practice defines test methods and general requirements at all phases of development, production, and field analysis of electrical terminals (including sense pins), connectors, and components that constitute the jump-start connection for road vehicles having 42 V (nominal) electrical systems. The 42 V jump start connector is always remote from the vehicle battery and may take the form of an in-line or Header Connection, either of which is in an accessible location for attachment of a jumper cable from an assist vehicle or battery charger. WARNING—The Jump Start Connector requires environmental protection. This specification assumes that such protection is in place and remains effective for the life of the vehicle. The level of protection depends on the vehicle packaging environment and duty cycle. Appendix B of this document contains the physical specification for the Jump Start Connector.

"Effective particle or domain size" is a phrase used in X-ray diffraction literature to describe the size of the coherent regions within a material which are diffracting. Coherency in this sense means diffracting as a unit. Small particle size causes X-ray line broadening and as such can be measured. It has been shown related to substructure as observed in transmission electron microscopy. Particle size is affected by hardening, cold working, and fatigue; conversely, there is increasing evidence that particle size, per se, affects both static and dynamic strength.
