Thermal Containment Efficiency of Sleeve Materials

2008-09-04
HISTORICAL
J2495_200809
This SAE Standard measures the percent thermal efficiency of materials in sleeve form used to contain heat or insulate around a hot component. The percent thermal efficiency (%TE) is determined by measuring the power difference expended by the heat source (cartridge heater) with and without the test sleeve at the specified temperature. See SAE J2302 to measure radiant heat flow of sleeves.

R134a Refrigerant Charge Determination Test Method

2018-09-11
CURRENT
J3023_201809
The purpose of this document is to establish guidelines for determining the critical R134a refrigerant charge for off-road, self-propelled work machines as defined in SAE J1116 and Agricultural Tractors as defined in ANSI/ASAE S390. It will develop a minimum to maximum refrigerant charge range in which the HVAC system can maintain proper operation. Operating conditions and characteristics of the equipment will influence the optimum charge. Since these conditions and characteristics vary greatly from one application to another, careful consideration should be taken to determine the optimum R134a refrigerant charge for the HVAC system.

Standard Rainflow File Format

2002-04-30
HISTORICAL
J2623_200204
This SAE Standard provides a definition of a rainflow file format. This type of simple text file would contain all relevant information about the rainflow cycle content of a time history. Included information are Comments, Signal Range, Signal Mean, Number of Cycles, Signal Maximum, Signal Minimum. Rainflow cycle counting has become the most accepted procedure for identifying material fatigue relevant cycles in complex variable amplitude load time histories. The cycle counting methods account for the effects of material plasticity and material memory of prior deformation, and the resulting compressed history information is used by durability analysts to estimate the effects of a given service or test history.

CURRENT
SSB1_003A
This document is an annex to EIA Engineering Bulletin SSB-1, Guidelines for Using Plastic Encapsulated Microcircuits and Semiconductors in Military, Aerospace and Other Rugged Applications (the latest revision). This document provides reference information concerning acceleration factors commonly used by device manufacturers to model failure rates in conjunction with statistical reliability monitoring. These acceleration factors are frequently used by OEMs in conjunction with physics of failure reliability analysis to assess the suitability of plastic encapsulated microcircuits and semiconductors for specific end use applications.

REDUCING DOWNTIME THROUGH THE USE OF PREDICTIVE ANALYTICS AND TECHNICAL TRAINING ADVANCEMENTS

2018-01-05
WP-0007
The exponential increase in the number of aircraft and air travelers has triggered new innovations aimed to make airline services more reliable and consumer friendly. Quick and efficient maintenance actions with minimum downtime are the need of the hour. Another major challenge is ensuring maintenance personnel are trained effectively; technology like augmented reality and Virtual Maintenance Trainers (VMTs) may provide safe and efficient training in lieu of live, instructor-led arrangements. And while traditional User/Maintenance Manuals provide useful information when dealing with simple machines, when dealing with complex systems of systems and miniaturized technologies, like unmanned aerial vehicles (UAVs), new technologies like augmented reality can rapidly and effectively support the maintenance operations.

HISTORICAL
USCAR23
This International Standard specifies the dimensions, test methods, and requirements for single core 60 V cables intended for use in road vehicle applications where the nominal system voltage is ≤ (60 V DC or 25 V AC). It also specifies additional test methods and/or requirements for 600 V cables intended for use in road vehicle applications where the nominal system voltage is > (60 V DC or 25 V AC) to ≤ (600 V DC or 600 V AC). It also applies to individual cores in multi-core cables. See ISO 6722 for “Temperature Class Ratings”.
