4.1 Light source products conforming to this specification are intended to be used in conjunction with coatings specially formulated with fluorescent colorants as a system for the visual detection of defects in industrial protective coatings.4.2 Visible fluorescence from the coating enhances the contrast of coating irregularities and defects and is produced by excitation of visible-activated fluorescent colorants in the coating.4.3 Light source products with defined wavelength and intensity properties are required to produce adequate visible fluorescence for easy visual location of defects.4.4 A light source product is considered to consist of a light source component incorporated into an optical, electrical, mechanical, and power supply system that makes it suitable for use in an industrial environment. The entire light source product is subject to this standard. The light source component and any subassemblies of the light source product are not subject to this standard.4.5 This specification is limited to light source products providing excitation in the range from 400 nm to 420 nm.AbstractThis specification provides the requirements for light source products intended for excitation of fluorescent materials used as a system for detection of defects in industrial coatings. This includes the examination of both longer wavelength fluorescing primer coatings as well as non-fluorescent top coatings. Also, this specification establishes the radiometric requirements of the light source product in terms of required wavelength range and minimum irradiance. Safety requirements shall be established for the light source product necessary to ensure the product will not pose a threat to visual health. Irradiance test method shall be performed to conform to the specified requirements, in accordance to the test method.1.1 This specification provides the requirements for light source products intended for excitation of fluorescent materials used as a system for detection of defects in industrial coatings. This includes the examination of both longer wavelength fluorescing primer coatings as well as non-fluorescent top coatings.1.2 This specification establishes the radiometric requirements of the light source product in terms of required wavelength range and minimum irradiance.1.3 This specification establishes safety requirements for the light source product necessary to ensure the product will not pose a threat to visual health.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

4.1 To show compliance with 14 CFR 23.1351, you must determine the electrical system capacity.4.2 14 CFR 23.1351(a)(2) states that:4.2.1 For normal, utility, and acrobatic category airplanes, by an electrical load analysis or by electrical measurements that account for the electrical loads applied to the electrical system in probable combinations and for probable durations; and4.2.2 For commuter category airplanes, by an electrical load analysis that accounts for the electrical loads applied to the electrical system in probable combinations and for probable durations.4.3 The primary purpose of the electrical load analysis (ELA) is to determine electrical system capacity (including generating sources, converters, contactors, bus bars, and so forth) needed to supply the worst-case combinations of electrical loads. This is achieved by evaluating the average demand and maximum demands under all applicable flight conditions. A summary can then be used to relate the ELA to the system capacity and can establish the adequacy of the power sources under normal, abnormal, and emergency conditions.NOTE 1: The ELA should be maintained throughout the life of the aircraft to record changes to the electrical system, which may add or remove electrical loads to the system.4.4 The ELA that is produced for aircraft-type certification should be used as the baseline document for any subsequent changes. When possible, the basic format of the original ELA should be followed to ensure consistency in the methodology and approach.4.5 The original ELA may be lacking in certain information, for instance, time available on emergency battery. It may be necessary to update the ELA using the guidance material contained in this guide.1.1 This guide covers how to prepare an electrical load analysis (ELA) to meet Federal Aviation Administration (FAA) requirements.1.2 This guide is intended to address aircraft level electrical load analysis. Electric propulsive power load analysis was not considered in the development of this guide.1.3 The values stated in SI units are to be regarded as standard.1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

5.1 Uranium hexafluoride is a basic material used to prepare nuclear reactor fuel. To be suitable for this purpose, the material must meet the criteria for isotopic composition. This test method is designed to determine whether the material meets the requirements described in Specifications C787 and C996.5.2 ASTM Committee C-26 Safeguards Statement:5.2.1 The material (uranium hexafluoride) to which this test method applies is subject to the nuclear safeguards regulations governing its possession and use. The analytical procedure in this test method has been designated as technically acceptable for generating safeguards accountability data.5.2.2 When used in conjunction with appropriate certified reference materials (CRMs), this procedure can demonstrate traceability to the national measurement base. However, adherence to this procedure does not automatically guarantee regulatory acceptance of the regulatory safeguards measurements. It remains the sole responsibility of the user of this test method to ensure that its application to safeguards has the approval of the proper regulatory authorities.1.1 This test method covers the isotopic analysis of uranium hexafluoride (UF6) and may be used for the entire range of 235U isotopic compositions for which standards are available.1.2 This test method is applicable to the determination of the isotopic relationship between two UF6 samples. If the abundance of a specific isotope of one sample (the standard) is known, its abundance in the other can be determined. This test method is flexible in that the number of times a given material is admitted to the ion source may be adjusted to the minimum required for a specified precision level.1.3 The sensitivity with which differences between two materials can be detected depends on the measuring system used, but ratio-measuring devices can generally read ratio-of-mol ratio differences as small as 0.0001.1.4 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. Specific hazards statements are given in Section 7.
