This document provides requirements and guidance for laser proponents and aviation authorities to determine the criteria that laser hazard control measures shall meet for the operation of an outdoor laser system in navigable airspace. This document has been developed to be used...
1.1 This test method covers the determination of total uranium, by mass concentration, in water within the calibrated range of the instrument, 0.1?μg/L or greater. Samples with uranium mass concentrations above the laser phosphorimeter dynamic range are diluted to bring the concentration to...
1.1 This practice provides: 1.1.1 Recommendations for the design and integration of an area scan camera system (referred to as "camera system") into a laser powder bed fusion (PBF-LB/M) machine to assess the health condition of the scanner protective window (SPW), 1.1.2 Recommendations for...
This SAE Aerospace Information Report (AIR) describes laser wire stripping technologies and recommendations to strip electrical single conductor wires and shielded cables intended for aerospace applications. These recommendations include: Laser types for wire stripping Laser...
1.1 This guide illustrates a test specimen geometry and testing protocol that can be used to assess the quality of a metal powder bed fusion build cycle as it could be affected by major system errors (for example, corrupted calibration, disrupted inert gas flow, laser wear) severely...
4.1 Generally, Raman spectra measured using grating-based dispersive or Fourier transform Raman spectrometers have not been corrected for the instrumental response (spectral responsivity of the detection system). Raman spectra obtained with different instruments may show significant variations in...
This specification establishes process controls for the repeatable production of aerospace parts by Laser Powder Bed Fusion (L-PBF). It is intended to be used for aerospace parts manufactured using Additive Manufacturing (AM) metal alloys, but usage is not limited to such applications.
4.1 Wavenumber calibration is an important part of Raman analysis. The calibration of a Raman spectrometer is performed or checked frequently in the course of normal operation and even more often when working at high resolution. To date, the most common source of wavenumber values is either...

The purpose of this report is to provide information on the results of ultraviolet (UV) laser marking and mark contrast measurement of a wide range of aerospace wire and cable constructions, the specifications for most of which do not state specific requirements for laser markability....
4.1 Single-use systems (SUSs) used for biopharmaceutical manufacturing must maintain sterility and product quality of the fluid inside. Such articles or systems should therefore be validated as providing an effective barrier against microbial ingress. The microbial barrier properties of a SUS may...
1.1 This specification covers laser beam or laser hybrid welded, built-up, carbon steel, sharp-cornered profiles (SCP) square, rectangular, or custom shape structural tubing for welded, riveted, or bolted construction. This specification does not include weathering steels, since most...
1.1 This practice covers routine testing of scanning Raman spectrometer performance and to assist in locating problems when performance has degraded. It is also intended as a guide for obtaining and reporting Raman spectra. 1.2 The values stated in SI units are to be regarded as standard. No other...
1.1 This test method is for the online determination of hydrogen sulfide (H2S) in natural gas using tunable diode laser absorption spectroscopy (TDLAS) analyzers also known as a "TDL analyzers." The particular wavelength for H2S measurement varies by manufacturer, typically between 1000 and...
4.1 Assessment of the spectrometer resolution and instrument line shape (ILS) function of a Raman spectrometer is important for intercomparability of spectra obtained among widely varying spectrometer systems, if spectra are to be transferred among systems, if various sampling accessories are to be...
1.1 This test method employs the signal-to-noise ratio to determine the sensitivity of a fluorescence measuring system in testing for the limit of detection (LOD) of quinine sulfate dihydrate in solution. The results obtained with quinine sulfate dihydrate in solution are suitable for specifying...
5.1 The present and growing international governmental requirements to add FAME (biodiesel, as specified in standards such as Specification D6751 and EN 14214) to diesel fuel has had the side effect of leading to potential FAME contamination of jet turbine fuel in multifuel transport facilities...
