Procedure for the Continuous Sampling and Measurement of Non-Volatile Particle Emissions from Aircraft Turbine Engines

2013-11-18
HISTORICAL
AIR6241
This SAE Aerospace Information Report (AIR) describes procedures, required continuous sampling conditions, and instrumentation for the measurement of non-volatile particle number and mass concentrations from the exhaust of aircraft gas turbine engines. Procedures are included to calculate sampling loss performance. This AIR is not intended for in-flight testing, nor does it apply to engine operating in the afterburning mode.

CURRENT
AIR6241A
This Aerospace Information Report (AIR) is a historical technical record describing procedures, required continuous sampling conditions, and instrumentation for the measurement of non-volatile particle number and mass concentrations from the exhaust of aircraft gas turbine engines. Procedures are included to calculate sampling loss performance. This AIR is not intended for in-flight testing, nor does it apply to engine operating in the afterburning mode. This Aerospace Information Report is a historical technical record of the initial document detailing the measurement of non-volatile particle emissions at the exit plane of aircraft gas turbine engines. This methodology was adopted by ICAO into Annex 16 Vol II and updated into Aerospace Recommended Practice ARP6320. Future updates of this document may include explanations of the reasoning and assumptions used to develop this measurement methodology.

Liquid Leak Tightness Standards for EVBattery Packs Recommended Practice

2022-03-28
WIP
J3277/1
This Recommended Practice proposes test practices to evaluate the Water Leak Tightness of Propulsion Battery Packs that emulates the equivalent results of IEC 60529 to an IPX7 level applying the Selected Equivalent Channel (EC) per SAE J3277 and provide guidelines for proper tooling design, validation, and leak test procedure. This practice is in consideration of the design limitation of some battery packs while utilizing applicable common air or tracer gas leak tightness technologies.

WIP
J3271
This document describes the megawatt-level DC charging system requirements for couplers/inlets, cables, cooling, communication and interoperability. The intended application is for commercial vehicles with larger battery packs requiring higher charging rates for moderate dwell time. A simplified analog safety signaling approach is used for connection-detection to guarantee de-energized state for unmated couplers with superimposed high speed data for EVSE-EV charging control and other value added services.

Performance Requirements for Nonmetallic Air Brake System Tubing

2014-08-26
WIP
J2547
This SAE Standard covers the minimum requirements for nonmetallic tubing as manufactured for use in air brake systems which tubing is different from that described in SAE J844. It is not intended to cover tubing for any portion of the system which operates continuously below - 40 degrees C or above +93 degrees C, above a maximum working gage pressure of 1.0 MPa, or in an area subject to attack by battery acid. This tubing is intended for use in the brake system for connections, which maintain a basically fixed relationship between components during vehicle operation. Coiled tube assemblies required for those installations where flexing occurs are covered by this document, SAE J1131 and SAE J2494-3, to the extent of setting minimum requirements on the essentially straight tube and tube fitting connections which are used in the construction of such assemblies.

Ambient Temperature Fixed Orifice Fueling

2016-11-21
WIP
J2601/4
SAE J#### establishes the protocol and process limits for hydrogen fueling of light duty vehicles when the fuel delivery temperature is not pre-cooled, so called “ambient fueling” designated by Table 1 of SAE J2601-2014. These process limits (including the fuel delivery temperature, the maximum fuel flow rate, the rate of pressure increase and the ending pressure) are affected by factors such as ambient temperature, fuel delivery temperature and initial pressure in the vehicle’s compressed hydrogen storage system. SAE J#### establishes standard fueling protocols based on a series of design cases representing fueling system engineering categories. These categories are intended to provide performance targets which allow decreasing fueling times relative to the most simple design case. Similar to the table and formula based approaches of SAE J2601-2014, this approach establishes a minimum performance criteria leaving open options for innovation to decrease fueling times.

Techniques for measuring the properties of lithium and lithium-ion battery anode active materials.

2017-10-18
WIP
J3159
This SAE RP provides a set of test methods and practices for the characterization of the properties of lithium battery anode active materials. Lithium battery anode active materials can be grouped in one of the following categories: lithium intercalation materials (including graphite, Li4Ti5O12); lithium alloying materials (including Sn, Si compounds/composites); lithium deposition materials (lithium metal). For the purposes of this document, material properties will be examined for particulate anode active materials (graphite, Li4TiO5, Sn compounds, Si compounds) and for metallic films (lithium metal). It is not within the scope of this document to establish criteria for the test results, as this is usually established between the vendor and customer It is not within the scope of this document to examine the electrochemical properties of anode materials since these are influenced by electrode design.
