V2X Sensor-Sharing for Cooperative & Automated Driving

2019-12-11
WIP
J3224
This project will provide requirements for a sensor-sharing message suitable for V2X-entities (RSUs, vehicles, VRUs) to describe detected road users, road obstacles and road impairments. The proposed work will define message structure, originating V2X entity requirements, information elements required to describe detected objects, including any changes identified for the J2735 data dictionary The proposed message will be designed in coordination with other SAE relevant projects and other SDO sensor-sharing efforts. This project is expected to result in a new message definition and recommended updates to J2735.

R-152a Refrigerant Electronic Leak Detectors, Minimum Performance Criteria

2019-12-10
WIP
J3221
This SAE Standard provides testing and functional requirements to meet specified minimum performance criteria for electronic probe-type leak detectors suitable for use with R-152a, an A2 flammable refrigerant. The equipment specified here will identify smaller refrigerant leaks when servicing motor vehicle air conditioning systems, including those engineered with improved sealing and smaller refrigerant charges to address environmental concerns and increase system efficiency.

R-152a Recovery/Recycling/Recharging Equipment for Flammable Refrigerants for Mobile Air-Conditioning Systems

2019-12-10
WIP
J3222
This SAE Standard applies to equipment to be used with R-152a refrigerant only. It establishes requirements for equipment used to recharge R-152a to an industry accepted accuracy level and purity levels defined in SAE J2099. Refrigerant service equipment is required to ensure adequate refrigerant recovery to reduce emissions and provide for accurate recharging of mobile air conditioning systems. Equipment shall be certified to meet all performance requirements outlined in this document and international/regional construction and safety requirements as outlined in this document.

Performance Levels and Methods of Measurement of Electromagnetic Compatibility of Vehicles, Boats (up to 15 m), and Machines (16.6 Hz to 18 GHz)

2019-12-09
WIP
J551/1
This SAE Standard covers the measurement of radio frequency radiated emissions and immunity. Each part details the requirements for a specific type of electromagnetic compatibility (EMC) test and the applicable frequency range of the test method. The methods are applicable to a vehicle, boat, machine or device powered by an internal combustion engine or battery powered electric motor. Operation of all engines or motors (main and auxiliary) of a vehicle, boat, machine or device is included. All equipment normally operating when the vehicle, boat, machine or device is in operation is included. Operator controlled equipment is included or excluded as specified in the individual document parts. As a special case, CISPR 12 applies to battery powered floor finishing equipment, but robot carpet sweepers are excluded. By reference, IEC CISPR 12 and CISPR 25 are adopted as the standards for the measurement of vehicle emissions.

CURRENT
ARP6621
This Aerospace Recommended Practice provides guidance for designers and specifiers of aircraft exterior lighting. Typical causes of light degradation and methods of predicting performance degradation in the aircraft environment are given. Although the document considers only exterior lighting, many of the principles and methods discussed apply to interior or flight deck lighting as well.

Lighting Applications for Unmanned Aircraft Systems (UAS)

2019-12-05
CURRENT
ARP6336
This SAE Aerospace Recommended Practice (ARP) provides technical recommendations for the lighting applications for Unmanned Aircraft Systems (UAS). The technical content of this ARP discusses the unique trade-offs that are necessary to maintain commonality to the U.S. Federal Aviation Regulations (FARs) for aerospace lighting. The recommendations set forth in this document are to aid in the design of Unmanned Aircraft (UA) lighting for the size of aircraft and operation for which the aircraft is intended. In addition, certain concepts of operation for which UASs are suited will require unique lighting solutions.

Aircraft Fuel System Design Guidelines

2019-12-05
CURRENT
AIR7975
This document describes the major design drivers and considerations when designing a fuel system for a large commercial aircraft. It discusses the design at a system/aircraft level, and is not intended as a design manual for individual system components, though it does refer out to other SAE specifications where more detail on specific components and sub systems is given. It does include examples of a number of calculations associated with sizing of fuel systems, based on those given in NAV-AIR-06-5-504, as well as an appendix summarizing basic fluid mechanical equations which are key for fuel system design. It is acknowledged that most of these calculations would today be performed by modelling tools, rather than by hand, but it is considered important for the designer to understand the principles. It is intended that later issues of this document will include appendices which give specific considerations for military aircraft, smaller commercial aircraft, and rotorcraft.
