Particle size analysis - Laser diffraction methods

This document provides guidance on instrument qualification and size distribution measurement of particles in many two-phase systems (e.g. powders, sprays, aerosols, suspensions, emulsions and gas bubbles in liquids) through the analysis of their light-scattering properties. It does not address the specific requirements of particle size measurement of specific materials.

This document is applicable to particle sizes ranging from approximately 0,1 µm to 3 mm. With special instrumentation and conditions, the applicable size range can be extended above 3 mm and below 0,1 µm.

For spherical and non-spherical particles, a size distribution is reported, where the predicted scattering pattern for the volumetric sum of spherical particles matches the measured scattering pattern. This is because the technique assumes a spherical particle shape in its optical model. For non-spherical particles the resulting particle size distribution is different from that obtained by methods based on other physical principles (e.g. sedimentation, sieving).

Lasers and laser-related equipment - Test methods for laser beam widths, divergence angles and beam propagation ratios - Part 3: Intrinsic and geometrical laser beam classification, propagation and details of test methods

ISO/TR 11146-3:2004 specifies methods for measuring beam widths (diameter), divergence angles and beam propagation ratios of laser beams in support of ISO 11146-1. It provides the theoretical description of laser beam characterization based on the second-order moments of the Wigner distribution, including geometrical and intrinsic beam characterization, and offers important details for proper background subtraction methods recommendable for matrix detectors such as CCD cameras. It also presents alternative methods for the characterization of stigmatic or simple astigmatic beams that are applicable where matrix detectors are unavailable or deliver unsatisfying results.

Geometrical product specifications (GPS) - Acceptance and reverification tests for coordinate measuring systems (CMS) - Part 10: Laser trackers

This document specifies the acceptance tests for verifying the performance of a laser tracker by measuring calibrated test lengths, according to the specifications of the manufacturer. It also specifies the reverification tests that enable the user to periodically reverify the performance of the laser tracker. The acceptance and reverification tests given in this document are applicable to laser trackers utilizing a retroreflector, or a retroreflector in combination with a stylus or optical distance sensor, as a probing system. Laser trackers that use interferometric measurement (IFM), absolute distance measurement (ADM) or both can be verified using this document. This document can also be used to specify and verify the relevant performance tests of other spherical coordinate measurement systems that use cooperative targets, such as “laser radar” systems. NOTE Systems which do not track the target, such as laser radar systems, will not be tested for probing performance. This document does not explicitly apply to measuring systems that do not use a spherical coordinate system. However, interested parties can apply this document to such systems by mutual agreement. This document specifies: — performance requirements that can be assigned by the manufacturer or the user of the laser tracker; — the manner of execution of the acceptance and reverification tests to demonstrate the stated requirements; — rules for proving comformity; — applications for which the acceptance and reverification tests can be used.

Standard Specification for Stainless Steel Laser and Laser Hybrid Welded Bars, Plates, Sharp-Cornered Profile (SCP), and Built-up Shapes

1.1 This specification covers laser and laser hybrid welded stainless steel bars, plates, sharp-cornered profile (SCP), and built-up shapes of structural quality for use in bolted or welded structural applications. SCP and built-up shapes are used in, but not limited to, the following applications: industrial and general structural applications like buildings, including architecturally exposed steel structures (AESS); architectural steel profiles, such as curtain wall and staircases. Note 1: The term laser fusion is also used to describe laser welding. 1.1.1 Supplementary requirements of an optional nature are provided. They shall apply only when specified by the purchaser. Note 2: Since the product covered by this specification is manufactured in small lots on dedicated production lines, minimum product quality requirements are ensured by requiring welding process specification and operator qualification at each manufacturing facility in accordance with AWS, ASME, or ISO requirements. If required, the purchaser can specify higher levels of weld inspection; supplementary requirements for mechanical and corrosion testing; and other requirements. Note 3: Because of the varying requirements of the end-use applications, different length tolerance and weld inspection levels may be specified. 1.2 Shapes covered in this specification include those defined in Article 3.1.2 of Specification A6/A6M , square and rectangular hollow sections, and additional shapes, including customized, that are made from two or more shapes, plates, bar, sheet, or strip. 1.3 This specification establishes the minimum requirements for manufacturing of laser and laser hybrid welded stainless steel shapes and requires the welds to, at a minimum, match the tensile and yield strength of the base metal. If base metals of different strengths are used, the lower strength base metal shall be matched. 1.4 This specification refers to Specifications A240/A240M , A276/A276M , or A479/A479M for chemical requirements, but the mechanical test requirements are determined by the mechanical properties section of this standard. This standard includes four strength grades. The default strength grade 1 is determined by the base metal standard. Grades 2 through 4 are for specification of higher strength levels. 1.5 The text of this specification contains notes and footnotes that provide explanatory material. Such notes and footnotes, excluding those in tables and figures, do not contain any mandatory requirements. 1.6 Units— This specification is expressed in both inch-pound units and in SI units; however, unless the purchase order or contract specifies the applicable M specification designation (SI units), the inch-pound units shall apply. The values stated in either inch-pound units or SI units are to be regarded separately as standard. Within the text, the SI units are shown in brackets. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the standard. 1.7 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. 1.8 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.

Guidance on Mitigation Strategies Against Laser Illumination Effects

This document is intended to give guidance to users, regulators and persons in the aviation field who may be affected by the potential visual interference effects of lasers aimed at aircraft by the general public. The potential effects include startle (distraction, disruption, disorientation, and operational incapacitation), glare, and flashblindness. This document provides mitigation strategies against such effects, including operational procedures, pilot education, and the use of Laser Glare Protection.   Prevention of harm from laser eye injuries is discussed but is not a focus of this document, due to the extremely low likelihood of injurious levels of laser light in typical aircraft illumination scenarios.   Devices for detecting and reporting hazardous laser illuminations are briefly described in Appendix D, but are not a focus of this document.   Some information in this document may also be useful for non-aviation users, such as persons driving vehicles. Additional information can be found in ANSI Z136.6, “Safe Use of Lasers Outdoors”.
