Long wave ultraviolet or UV-A irradiation (between 320 and 400 nm) is used for fluorescent inspections in magnetic particle and liquid penetrant examinations. UV-A irradiation is obtained from either LED, fluorescent, or high intensity discharge lamps that are stationary or portable. Commercially available UV-A lamps possess a large variation in intensity output that may introduce a legitimate concern for possible health hazards. This document reviews the nature of UV-A irradiation emitted by lamps and acceptable UV dosage limits adopted by the American Conference of Governmental Industrial Hygienists (ACGIH®) and European Union and recommendation of proper practices when working with UV-A irradiation.

The purpose of this section is to provide methods and a set of convenient working charts to estimate penalty values in terms of take-off fuel weight for any given airplane mission. The curves are for a range of specific fuel consumption (SFC) and lift/drag ratio (L/D) compatible with the jet engines and supersonic aircraft currently being developed. A typical example showing use of the charts for an air conditioning system is given. Evaluation of the penalty imposed on aircraft performance characteristics by the installation of an air conditioning system is important for two reasons: 1 It provides a common denominator for comparing systems in the preliminary design stage, thus aiding in the choice of system to be used. 2 It aids in pinpointing portions of existing systems where design improvements can be most readily achieved. All factors that influence the flight performance of an aircraft can be expressed in terms of weight, external and momentum drags, and changes in powerplant
This specification covers steel forgings suitable for use in the construction of aircraft/aerospace equipment, special ordnance, and related accessories.
This SAE Recommended Practice provides recommended guidelines and best practices for implementing a supportability program to ensure that software is supportable throughout its life cycle. This Implementation Guide is the companion to the Software Supportability Program Standard, SAE JA1004, that describes, within a Plan-Case framework, what software supportability performance requirements are necessary. This document has general applicability to all sectors of industry and commerce and to all types of equipment whose functionality is to some degree implemented via software. It is intended to be guidance for business purposes and should be applied when it provides a value-added basis for the business aspects of development, use, and sustainment of support-critical software. Applicability of specific recommended practices will depend on the support-significance of the software, application domain, and life cycle stage of the software.
This specification covers a low-alloy steel in the form of welding wire.
This SAE Aerospace Standard (AS) covers requirements for nickel-chromium coatings, black oxide or black phosphate coatings, and alternative coatings for aerospace hand tools.
This SAE Aerospace Recommended Practice (ARP) is intended to be used for laser systems mounted on aircraft and propagated into navigable airspace. This does not include lasers onboard aircraft where the beam is contained within an enclosure so that the beam cannot enter into airspace, nor does it include lasers from satellites and spacecraft in outer space. It may be used in conjunction with AS4970, ARP5535, ARP5572, ARP5293, and the ANSI Z136 laser safety standards.
This document provides methods and techniques for implementing a reliability program throughout the full life cycle of a software product, whether the product is considered as standalone or part of a system. This document is the companion to the Software Reliability Program Standard [JA1002]. The Standard describes the requirements of a software reliability program to define, meet, and demonstrate assurance of software product reliability using a Plan-Case framework and implemented within the context of a system application. This document has general applicability to all sectors of industry and commerce and to all types of equipment whose functionality is to some degree implemented by software components. It is intended to be guidance for business purposes and should be applied when it provides a value-added basis for the business aspects of development, use, and sustainment of software whose reliability is an important performance parameter. Applicability of specific practices will
This SAE Standard provides a framework for the management of software reliability within system reliability requirements. It is based around the Software Reliability Plan and Software Reliability Case and emphasizes the importance of evaluating progress towards meeting software reliability requirements throughout the project life-cycle.
The Mounting Height Task Force was tasked to determine the extent of the problem(s) associated with vehicle headlamps mounted at or above the level of the mirror(s) in passenger vehicles; the level of glare exposure caused by high-mounted headlamps; the appropriate height differential needed to maintain a glare level consistent with past and/or current passenger vehicle headlamp mounting; and the necessary headlamp mounting height necessary to control mirror glare at an accepted/acceptable level. The report herein addresses these passenger vehicle mounting height issues.
While this report does not include a discussion of all of the available data defining human response or address all body areas, for those areas addressed it does utilize references generally judged by those in the field to be practical and meaningful guidelines for the development of human surrogates. This report is intended to be a “living” document that will be updated periodically. A number of problems need to be addressed in defining human impact response characteristics. There is the problem of human response variability from subject to subject in volunteer tests. There is the problem of extrapolating such volunteer data which are obtained at low impact severities to higher impact severities using human cadaver response data obtained at injurious levels of impacts. Live animal experiments have been conducted over the years in an attempt to define human impact response and tolerance. The problem with using animal response data is the lack of geometric scaling techniques needed to
This specification covers a perfluoroether elastomer in the form of molded rings.
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.

Inclusion of dimensional data in this document is not intended to imply all of the products described therein are stock production sizes. Consumers are requested to consult with manufacturers concerning lists of stock production sizes.
Following a number of high-visibility collisions between aircraft on the airport surface, overall taxi operations have been brought under greater scrutiny. In addition, observation of taxi operations and the results of associated research programs have revealed that the efficiency of taxi operations could be significantly improved with available technologies and by applying a human centered design approach. Surface operations displays have been tested in prototype form and a number of manufacturers are moving toward product definition. This document provides guidance on the design of elements, which may be part of surface operations displays whose objectives would be to enhance safety and to improve overall efficiency of aircraft operations on the airport surface. Such efficiency increases should be realized not only in day-to-day operations, but should also be manifested in training for surface operations. This document sets forth functional and design recommendations concerning the
