1.1        This document is intended to be used to assign part classifications across the aviation industries that use AM to produce parts. 1.2        This document is applicable to all AM technologies defined in ISO/ASTM 52900 used in aviation. 1.3        This document is intended to be used to establish a metric for AM parts in downstream documents. 1.4        This document is not intended to…

This document covers procedures for using radiationsensitive indicators (referred to hereafter as indicators) in radiation processing. These indicators may be labels, papers, inks or packaging materials which undergo a visual change when exposed to ionizing radiation (1-5). The purpose for using indicators is to determine visually whether or not a product has been irradiated, rather than to…

1.1 This document outlines dosimetric procedures to be followed for the radiation-induced reproductive sterilization of live insects for use in pest management programs. The primary use of such insects is in the Sterile Insect Technique, where large numbers of reproductively sterile insects are released into the field to mate with and thus control pest populations of the same species. A secondary…

1.1 This is a practice for using a radiochromic optical waveguide dosimetry system to measure absorbed dose in materials irradiated by photons and high energy electrons in terms of absorbed dose to water. The radiochromic optical waveguide dosimetry system is generally used as a routine dosimetry system.1.2 The optical waveguide dosimeter is classified as a Type II dosimeter on the basis of the…

This practice covers dosimetric procedures to be followed in installation qualification, operational qualification and performance qualification (IQ, OQ, PQ), and routine processing at electron beam facilities to ensure that the product has been treated with an acceptable range of absorbed doses. Other procedures related to IQ, OQ, PQ, and routine product processing that may influence absorbed…

This practice covers the preparation and use of semiadiabatic calorimetric dosimetry systems for measurement of absorbed dose and for calibration of routine dosimetry systems when irradiated with electrons for radiation processing applications. The calorimeters are either transported by a conveyor past a scanned electron beam or are stationary in a broadened beam. This document is one of a set of…

1.1 This is a practice for using polymethylmethacrylate (PMMA) dosimetry systems to measure absorbed dose in materials irradiated by photons or electrons in terms of absorbed dose to water. The PMMA dosimetry system is generally used as a routine dosimetry system. 1.2 The PMMA dosimeter is classified as a Type II dosim-eter on the basis of the complex effect of influence quantities (see ISO/ASTM…

1.1 This practice describes the operation and production control of metal powder bed fusion (PBF) machines and processes to meet critical applications such as commercial aerospace components and medical implants. The requirements contained herein are applicable for production components and mechanical test specimens using powder bed fusion (PBF) with both laser and electron beams. 1.2 This…

1.1 This practice covers the preparation, handling, testing, and procedure for using the ethanol-chlorobenzene (ECB) dosimetry system to measure absorbed dose to water when exposed to ionizing radiation. The system consists of a dosimeter and appropriate analytical instrumentation. For simplicity, the system will be referred to as the ECB system. The ECB dosimeter is classified as a type I…

This is the third edition of CAN/CSA-Z259.2.3, Descent devices, which is an adoption, with Canadian deviations, of ISO (International Organization for Standardization) Standard 22159 (first edition, 2007-05-15), entitled Personal equipment for protection against falls — Descending devices. The title has been changed for the CSA Group Standard to ensure continuity with previous editions of this…
