J826/3 CAD Model of Legs and Back Hardware for SAE J826 3-D H-Point Machine

This document describes the CAD model data of legs and back hardware available from SAE for the HPM-1 three-dimensional H-point machine. The elements of the CAD model include the feet, lower and thighs as well as headroom probe and t-bar. Also included are datum points and lines, and calibration references. The intended purpose for this information is to provide a CAD reference for design and benchmarking as well as a calibration reference for the physical HPM-1 audits. The content and format of the data files that are available are also described. The actual CAD model files are included with this product and are provided in the following formats: CATIA v4 (without parametrics), CATIA v5 (without parametrics), IGES, and STEP.

Air Conditioning Service Procedures for Heavy duty and Off-Highway work Machines using R-134a refrigerant

This recommended practice provides technicians with safe and efficient techniques and general equipment recommendations for servicing Mobile Air Conditioning (MAC) systems in heavy duty and off-highway work machines. Presently, R-134a is the only approved refrigerant for use in mobile heavy duty and off-highway equipment and therefore this document primarily covers the servicing of R-134a systems. Since the technician may encounter other refrigerants a brief explanation on the identification safe handling of each refrigerant will be introduced.

Model Based Functional Safety

Provides standard guidance on major tasks and activities and how to implement and manage Functional Safety and software system safety aspects of Model Based System Engineering (MBSE). Process focus is on safety-critical functions (SCF) of complex software intensive systems being modeled and depicted graphically as part of MBSE and software engineering to ensure safety engineering aspects are tracked and captured as part of models to enhance safety documentation and produce objective safety evidence.

Off-Road Self-Propelled Work Machines Operator enclosure environment Part 4:Heating, ventilating and air conditioning (HVAC) test method and performance

J3078/4 specifies a uniform test method for measuring the contribution to operator environmental temperature provided by a heating, ventilating and air conditioning system operating in a specific ambient environment. The method might not determine the complete climatic environment of the operator since this is also affected by heat load from sources other than those on the machine, for example solar heating. J3708/6 is to be used in conjunction with J3078/4 to determine more accurately the complete heat loading on the operator enclosure. Minimum performance levels for the machine’s operator enclosure heating, ventilating and air conditioning systems are established in J3708/4.

Concepts, Terms and Definitions Related to Surrogate Measures of Safety

The document will define and describe in condensed form the fundamental theoretical concepts of surrogate measures of safety and define indicators (with variations). To the extent possible, the definitions should be kept neutral with respect to the technology or data collection method used as these change rapidly.

Camera Monitor Systems Test Protocols and Performance Requirements

This SAE Recommended Practice provides test protocols with performance requirements for Camera Monitor Systems to replace existing statutorily required inside and outside rear-view mirrors for US market road vehicles. This practice expands specific technical content while retaining harmonization with the FMVSS 111 Rear Visibility standard, and other international standards. This is accomplished by defining required roadway fields of view as specific fields of view (FOV) displayed inside the vehicle. Specific testing protocols and/or specifications are added to enhance ease of use using straightforward language and any specifications are intended to be independent of different camera and display technologies unless otherwise explicitly stated.

Vehicle Sound Measurement at Low Speeds

The Vehicle Sound for Pedestrians Subcommittee of the SAE Safety and Human Factors Committee is developing a test procedure to determine the sound output of electric and hybrid-electric powertrain vehicles at certain low-speed conditions. Establishing a consistent method of measuring the sound output of these vehicles will facilitate further study into the need for additional measures to alert pedestrians to the presence of these vehicles in traffic. This test procedure could also become industry practice should it later be deemed necessary to record the sound output of certain vehicles in low speed traffic conditions where vehicles, pedestrians and other road users are co-mingled.

Impact testing of automotive fuel tanks

Drop testing and "sled" testing are used regularly to demonstrate integrity of plastic fuel systems. This document defines test method, application and rationale for fuel tank impact testing.
