This document describes the procedures to prepare plutonium sources and  to measure the activity ratio of 238Pu to (239Pu + 240Pu) by alpha spectrometry. The alpha spectrometry method is used for the determination of isotopic abundance of 238Pu in combination with isotope amount ratios determined by mass spectrometry and eliminates the possible isobaric interferences of 238U in the latter method. It is applied to the analysis of purified solutions of plutonium in 2 mol/l to 4 mol/l nitric acid containing 50 µg to 200 µg of plutonium per millilitre, as may result from the chemical treatment and purification preceding plutonium isotopic analysis by mass spectrometry. This document is applied to plutonium solutions free from 241Am and those containing less than 10 % of other non-volatile impurities relative to the plutonium content. Otherwise purification should be carried out in accordance with ISO 8299[1]. The methods provided in this document are intended for use in conjunction or in parallel with mass spectrometry for the isotopic analysis of plutonium in spent-fuel solutions or nuclear-grade plutonium products.

 

This document specifies the mechanical properties of wrought aluminium and wrought aluminium alloy sheet, strip and plate for general engineering applications. It does not apply to semi-finished rolled products in coiled form to be subjected to further rolling (reroll stock) or to special products such as corrugated, embossed, painted, sheets and strips or to special applications such as aerospace, can stock, finstock, for which mechanical properties are specified in separate European Standards. The chemical composition limits of the alloys are specified in EN 573 3. Temper designations are specified in EN 515.

 

ISO 23146:2012 specifies a method for the determination of the fracture toughness of advanced technical ceramics. The procedure makes use of single-edge V-notched bars, which are loaded in four-point bending until failure. It is applicable to monolithic ceramics with a grain size or major microstructural feature size larger than about 1 µm. The use of ISO 23146:2012 for yttria tetragonal zirconia polycrystal material (Y-TZP) is not recommended. The method might also be unsuitable for some other very tough or soft ceramics in which a sharp crack does not form at the root of the V-notch.

ISO 14918:2018 is applicable when the thermal sprayer's qualification is required by this document, the purchaser, by inspection authorities or by other organizations. The thermal spraying processes referred to in this document include those spraying processes which are designated as manual or mechanized.

This Part of this European Standard specifies the requirements for fabrication and installation of piping systems, including supports, designed in accordance with EN 13480-3:2017.

 

This document specifies the definition and classification of steels. It defines the term "steel" (see clause 3) and it classifies the steel grades as main criteria by the chemical composition into non-alloy, low-alloy and high-alloy steels. Micro-alloy steels are a subclass of low alloy steels and stainless steels are a subclass of high-alloy steels.

 

This document provides guidance and requirements for risk assessment and implementation of prevention and protection measures relating to material extrusion-based additive manufacturing with polymer materials. The risks covered by this document concern all sub-processes composing the manufacturing process, including the management of waste. This document does not specify requirements for the design of machinery and equipment used for additive manufacturing.

It stipulates the determination methods of total silicon, total nitrogen, aluminium, iron, calcium, oxygen, carbon, fluorine, and chlorine in fine silicon nitride powders.

 

ISO 463:2006 specifies the most important design and metrological characteristics of mechanical dial gauges.

 

This document describes methods for the measurement of the insertion loss of hearing protection devices at supra-threshold levels of impulsive noise using an acoustical test fixture (ATF). The ATF is an anthropometric fixture and contains two ear simulators for the purpose of testing hearing protection devices. The standard establishes uniform instrumentation, calibration, and electroacoustic requirements including details regarding the sound field of test facilities, and the acoustical characteristics of ATFs. The procedures described utilize signals at sound levels representative of applications in which hearing protection devices are worn, ranging from 130 dB to 170 dB peak sound pressure level (SPL). These procedures are intended to provide quick, economical, and repeatable objective (not psychophysical) measurement techniques that can be used as additions or complements to the real-ear attenuation at threshold (REAT) measurement method specified in ISO 4869-1. Methods for estimating attenuation values are provided, combining the measured insertion loss with real-ear attenuation measurements of the device with deliberate active or passive sound transmission mechanisms occluded or disabled, resulting in the impulsive level-dependent attenuation (ILDA). Other metrics are defined (the impulsive A-weighted level attenuation (ILAA) and impulsive peak-level attenuation (IPLA)); these are intended for use in estimating effective SPLs when hearing protectors are worn.

This document provides a procedure for the evaluation of irradiation data in the region between the reactor core and the inside surface of the containment vessel, through the pressure vessel and the reactor cavity. NOTE These irradiation data could be neutron fluence or displacements per atom (dpa), and Helium production. The evaluation employs both neutron flux computations and measurement data from in-vessel and cavity dosimetry, as appropriate. This document applies to pressurized water reactors (PWRs), boiling water reactors (BWRs), and pressurized heavy water reactors (PHWRs). This document also provides a procedure for evaluating neutron damage properties at the reactor pressure vessel and internal components of PWRs, BWRs, and PHWRs. Damage properties are focused on atomic displacement damage caused by direct displacements of atoms due to collisions with neutrons and indirect damage caused by gas production, both of which are strongly dependent on the neutron energy spectrum. Therefore, for a given neutron fluence and neutron energy spectrum, calculations of the total accumulated number of atomic displacements are important data to be used for reactor life management.

 

This document specifies fundamental techniques of film and digital radiography with the object of enabling satisfactory and repeatable results to be obtained economically. The techniques are based on generally recognized practice and fundamental theory of the subject. This document applies to the radiographic examination of steel pipes for service induced flaws such as corrosion pitting, generalized corrosion and erosion. Besides its conventional meaning, “pipe” as used in this document is understood to cover other cylindrical bodies such as tubes, penstocks, boiler drums and pressure vessels. Complex geometry components such as bends and tees can present additional challenges that can complicate their inspection by the techniques described in this document. Weld inspection for typical welding process induced flaws is not covered, but weld inspection is included for corrosion/erosion type flaws. The pipes can be insulated or not, and can be assessed where loss of material due, for example, to corrosion or erosion is suspected either internally or externally. This document covers the tangential inspection technique for detection and through-wall sizing of wall loss, including with the source: a) on the pipe centre line; and b) offset from pipe centre line by the pipe radius. This document covers double wall radiography, and note that the double wall double image technique is often combined with tangential radiography with the source on the pipe centre line. This document applies to tangential radiographic inspection using industrial radiographic film techniques, computed radiography (CR) and digital detector arrays (DDA).
