Low-Duty Inertia Dynamometer Hydraulic Brake Wear Test Procedures for Vehicles Above 4536 kg (10000 pounds) of GVWR

2024-04-24
WIP
J3006
This Recommended Practice is derived from OEM and tier-1 laboratory tests and applies to two-axle multipurpose passenger vehicles, or trucks with a GVWR above 4536 kg (10 000 pounds) equipped with hydraulic disc or drum service brakes. Before conducting testing for a specific brake sizes or under specific test conditions, review, agree upon, and document with the test requestor any deviations from the test procedure. Also, the applicable criteria for the final test results and wear rates deemed as significantly different require definition, assessment, and proper documentation; especially as this will determine whether or not Method B testing is needed. This Recommended Practice does not evaluate or quantify other brake system characteristics such as performance, noise, judder, ABS performance, or braking under extreme temperatures or speeds. Minimum performance requirements are not part of this recommended practice.

Liquid Leak Tightness Evaluation Methodology for EV Battery Packs Informational Report

2024-04-23
CURRENT
J3277_202404
This technical information report (IR) presents a methodology to evaluate battery pack liquid leak tightness attributes to be used in a production line to satisfy the functional requirement for IPX7, water ingress requirement, and no sustainable coolant leakage for coolant circuits. The Equivalent Channel Method is used as a suggested production leak tightness requirement for a given battery pack design that will correlate and assure that the battery pack meets or exceeds its functional requirement. Obtaining the specific geometry of the Equivalent Channel (EC) for a given battery pack is done analytically and empirically in consideration of the product design limitations. This document is a precursor to J3277-1, which will present the practices to qualify that product leak tightness is equal or better than the maximum allowed EC for that product using applicable and commercially available leak test technologies.

Safety Assessment of Transport Airplanes in Commercial Service

2024-04-16
WIP
ARP5150B
This document describes guidelines, methods, and tools used to perform the ongoing safety assessment process for transport airplanes in commercial service (hereafter, termed “airplane”). The process described herein is intended to support an overall safety management program. It is associated with showing compliance with the regulations, and also with assuring a company that it meets its own internal standards. The methods identify a systematic means, but not the only means, to assess ongoing safety.While economic decision-making is an integral part of the safety management process, this document addresses only the ongoing safety assessment process. To put it succinctly, this document addresses the “Is it safe?” part of safety management; it does not address the “How much does it cost?” part of the safety management.This document also does not address any specific organizational structures for accomplishing the safety assessment process.

ARP5151B
This document describes a process that may be used to perform the ongoing safety assessment for (1) GAR aircraft and components (hereafter, aircraft), and (2) commercial operators of GAR aircraft. The process described herein is intended to support an overall safety management program. It is to help a company establish and meet its own internal standards. The process described herein identifies a systematic means, but not the only means, to assess continuing airworthiness.Ongoing safety management is an activity dedicated to assuring that risk is identified and properly eliminated or controlled. The safety management process includes both safety assessment and economic decision-making. While economic decision-making (factors related to scheduling, parts, and cost) is an integral part of the safety management process, this document addresses only the ongoing safety assessment process.

High Flow Liquid Hydrogen Fueling Couplings for Aerospace and Heavy Transport Applications

2024-04-15
WIP
AIR8999
The SAE AE-5CH Taskgroup has determined that high flow liquid hydrogen fueling couplings need to be developed in order to fast fill aircraft at the airport. Though the flow rates from a current liquid hydrogen bayonet connect may reach the lower bound flow rates of regional aircraft, there are some shortcomings to this connector for aerospace. For this reason a new specification for flow rates for regional to narrowbody (and potentially later widebody) are to be developed in this documenet. Harmonization for lower flow rates (such as up to 20kg/minute) are planned to be harmonized with ground vehicle fueling such as with ISO 13984. Within this document,coupling descriptions including Flow rates from 84 to 200 kg/minute will be evaluated (and potentially higher), and requirements and testing and safety targets will be specified.

WIP
ARP8998
This document defines a consistent industry approach on engine and and auxillary power unit (APU) wiring to meet aircraft EWIS fire and flammability requirements. EWIS regulations apply to many different aircraft types that have propulsion systems certified to FAA 14 CFR part 33 & EASA CS-E. This document will compare these aircraft regulations and then reference the current 14 CFR part 33 requirements for propulsion systems to demonstrate how they can be leveraged to show compliance to EWIS requirements for all aircraft types. APUs are certified to the aircraft level requirements and are included in this document to clarify the type of data suggested to meet the Part/CS-25 EWIS requirement and/or associated normal aircraft regulations.
