For calculating the true relative density the mass of water displaced by a known masss of dry coke, ground to pass a sieve of nominal size of openings 212 um, is determined using a pyknometer. - The volume of a large amount of coke is determined by displacement in water; dividing the mass of the dried coke by the mass of an equal volume of water gives the apparent relative density. - The porosi…
Specifies a method designed to check the long-term stability of a solid to alpha disintegration by detection of all modifications in the properties of an irradiated sample. The solid is borosilicate glass or, as an alternative, ceramics or glass-ceramics and a two-phase mixture of glass beads dispersed in a metal matrix, made from adequate (stable) fission product elements spiked with appropria…
Gives the technical delivery requirements for blooms, billets, slabs, bars, wire rod and bright steel manufactured from the steels listed in table 3 and supplied in one of the heat-treatment conditions given in table 1 and in one of the surface conditions given in table 2. Covers three groups of wrought free-cutting steels for mechanical purposes (not intended for heat treatment, suitable for c…
Specifies the methods for revealing the grain and for estimating the mean size of the grain revealed. Includes a counting method (annex A) and determination of grain size by using of standard charts (annnexes B and C) taken from an AFNOR Standard and an ASTM document, respectively.
Identifies the typical parameters of a component that permit it to be characterized unequivocally and to allow the corresponding reliability data to be associated with those of other components having equivalent typical parameters. Parameters refer to technical characteristics including the physical principle of operation and quality level and to actual operating conditions and maintenance and …
This Safety Guide provides guidance on the development, content and use of operational limits and conditions (limits on plant operating parameters) and operating procedures that affect them. It recommends how to meet the requirements established in Safety Standards Series No. NS-R-2, Safety of Nuclear Power Plants: Operation, setting out the responsibilities of the operating organization in set…
Specifies the method for determining the ability of wire of diameter or thickness 0,3 to 10 mm inclusive to undergo plastic deformation during simple torsion. The test consists of twisting a test piece of wire around its own axis in one direction.
n 17 November 1992 a radiological accident occurred at an electron accelerator facility in Hanoi, Viet Nam. An individual entered the irradiation room without the operators' knowledge and unwittingly exposed his hands to the X ray beam. His hands were seriously injured and one hand had to be amputated. The report details the circumstances of the accident, its medical consequences and the govern…
The detection of flaws in an item submitted to X- or gamma-radiographic examination depends on the particularities of the technique employed. This part of ISO 1106 specifies general techniques of weld radiography with the object of enabling satisfactory results to be obtained economically. The techniques are based on generally accepted practice and the fundamental theory of the subject.
This part of ISO 8529 is closely related to two other standards concerning the calibration of dosimeters and dose-rate meters for neutron radiation. The first standard, ISO 8529-1 (in preparation), specifies the reference neutron radiations, in the energy range from thermal up to 20 MeV, and their production methods. The second standard, ISO 8529-2 (in preparation), describes fundamentals relat…
