This recommended practice is applicable to the construction, reconstruction, and modification, of ready-mixed concrete trucks. This RP is not mandatory but is a consensus of industry best practices. It is not intended to override or replace OEM vehicle specifications, existing government regulations and other sources that are related to this RP.

The intent of this document is to develop a recommended practice for PEV chargers, whether on-board or off-board the vehicle, that will enable equipment manufacturers, vehicle manufacturers, electric utilities, and others to make reasonable design decisions regarding power quality. The three main purposes are as follows:

SAE J2894/2 will describe the test methods for the parameters/requirements in this document.

Technician training is required to ensure that recommended procedures are used for service and repair of Mobile Air Conditioning (MAC) systems using R-744 and/or R-1234yf. Unique requirements for each refrigerant are detailed within this standard. Technicians may be trained in either or both refrigerants. The technician shall be trained to recognize which refrigerant is being handled, how to handle it safely and be equipped with the essential information, proper equipment and tools, which are unique to these refrigerants. This standard outlines minimum content requirements for such training programs. Training programs designed in accordance with this standard are not intended to ensure or assess the technical skills of technicians regarding the diagnosis and repair of motor vehicle air conditioners. Rather, the goal of such programs is to provide information to technicians about safely handling refrigerants.

These general guidelines and precautions apply to personnel operating directional drilling tracking equipment when used with Horizontal Earthboring Machines as defined in SAE J2022.

This SAE standard applies to horizontal earthboring machines (SAE J2022) of the following types:

1. a
   Auger boring machines;
2. b
   Rod pushers;
3. c
   Rotary rod machines;
4. d
   Impact machines.

This document does not apply to specialized horizontal directional drills, mining machines, conveyors, tunnel boring machines, pipe jacking systems, micro tunnelers, or well drilling machines.

This SAE Recommended Practice establishes a ballistic tank test procedure for evaluating inflator assemblies used in inflatable restraint systems. It is intended to be a general procedure for repetitive testing and suggests only general guidelines for the safe conduct of tests and data correlation. Uniform test requirements, test procedures, and data recording requirements are specified. The intent of the document is to provide a procedure employing a ballistic tank test method for determining the ability of an inflator to meet requirements for deploying inflatable restraint systems. A ballistic tank test is described which will yield repeatable and comparable results for evaluating a given inflator configuration's pressure output versus time. Use of the ballistic tank test for comparison of various inflator technologies may be of limited value due to differences in gas temperature, gas composition and mass flow effects on airbag performance as it relates to occupant protection.

This SAE Recommended Practice describes a method to be used for the static deployment of airbag module assemblies. The results obtained from the deployment tests will be used to verify compliance with design requirements and/or specifications, and for other engineering purposes such as module performance comparisons, and/or CAE input or validation. The purpose for this procedure is to describe recommended test methods to ensure, to the extent possible, reliable and reproducible test results for driver airbag modules, passenger airbag modules, or other airbag modules (e.g., side airbags, roof rail airbags, knee bolster airbags, etc.). Performance limits or acceptance criteria are not established as they are typically defined based on specific vehicle design requirements and/or manufacturer specifications. It is intended to be a general procedure for repetitive testing and suggests only general guidelines for the safe conduct of tests and reliable data correlation.

This test procedure provides a standard method for evaluating the side stand retraction performance of a side stand/motorcycle combination.
