This document gives specific procedures for industrial X-ray and gamma radiography for discontinuity detection purposes, using NDT (non-destructive testing) film techniques. This part of the EN 12681 series specifies the requirements for film radiographic testing of castings. Films after exposure and processing become radiographs with different area of optical density. Radiographs are viewed and evaluated using industrial radiographic illuminators. This part of the EN 12681 series specifies the recommended procedure for the choice of operating conditions and radiographic practice. These procedures are applicable to castings produced by any casting process, especially for steel, cast iron, aluminium, cobalt, copper, magnesium, nickel, titanium, zinc and any alloys of them. NOTE This document considers EN ISO 5579. This document does not apply to: - radiographic testing of castings for aerospace applications (see EN 2002-21); - radiographic testing of welded joints (see EN ISO 17636-1); - radiography with digital detectors (see EN 12681-2); - radioscopic testing (see the EN 13068 series).

 

This document gives specific procedures for industrial X-ray and gamma radiography for discontinuity detection purposes, using NDT (non-destructive testing) digital X-ray image detectors. This part of the EN 12681 series specifies the requirements for digital radiographic testing by either computed radiography (CR) or radiography with digital detector arrays (DDA) of castings. Digital detectors provide a digital grey value image which can be viewed and evaluated using a computer. NOTE This part of the EN 12681 series complies with EN 14784-2 for CR. Some clauses and annexes are taken from EN ISO 17636 2. This part of the EN 12681 series specifies the recommended procedure for detector selection and radiographic practice. Selection of computer, software, monitor, printer and viewing conditions are important but are not the main focus of this document. The procedure specified in this document provides the minimum requirements for radiographic practice which permit exposure and acquisition of digital images with equivalent sensitivity for detection of imperfections as film radiography, as specified in EN 12681 1. This document does not consider radiographic or radioscopic fitness for purpose testing as applied for specific castings based on manufacturer’s internal requirements and procedures. The requirements on image quality in testing class A and B testing of Annex A consider the good workmanship quality for general casting applications as also required in EN 12681 1 for film radiography. The testing classes AA and BA reflect the quality requirements of current automated and semi-automated radiographic testing systems with DDAs and computer- or operator-based image evaluation, and mini- or micro-focus tubes (spot size = 1 mm) with reduced requirements to the unsharpness, but unchanged requirements to contrast sensitivity as also required in EN 12681 1 for film radiography. The specified procedures are applicable to castings produced by any casting process, especially for steels, cast irons, aluminium, cobalt, copper, magnesium, nickel, titanium, zinc and any alloys of them. This document does not apply to: - the testing of welded joints (see EN ISO 17636 2); - film radiography (see EN 12681 1); - real time testing with radioscopy (see EN 13068 1; radioscopy with image intensifiers).

This document defines a harmonized way to assess the braking performance by test of locomotives, passenger coaches, freight wagons, railbound construction and maintenance machines, and self-propelled passenger trains (multiple units) including high speed trains. The document sets out the standardized method for undertaking brake performance tests and the correction factors to be applied to the data obtained for all types of rolling stock. This document also defines the methods to assess the brake performance in terms of stopping distance, and from this the process to determine vehicle(s) deceleration and braked weight. It then deals with conversion of the braked weight to the braked weight percentage of a vehicle or train for operating purposes. It also sets out additional factors when determining the braked weight percentage of a train calculated from specified braked weight, depending on the formation of the train. In Annex D there is a method for determining brake performance of freight wagons fitted with P10 cast iron or LL-blocks using limited testing (force measurement).

This document specifies the crucial steps of a quantitative polymerase chain reaction (qPCR) method to measure the abundance of selected microbial gene sequences from soil DNA extract. The number of microbial gene sequences quantified by qPCR provides an estimation of the abundance of selected microbial groups in soil.

 

ISO 17601:2016 specifies the crucial steps of a quantitative real-time polymerase chain reaction (qPCR) method to measure the abundance of selected microbial gene sequences from soil DNA extract which provides an estimation of selected microbial groups. It is noteworthy that the number of genes is not necessarily directly linked to the number of organisms that are measured. For example, the number of ribosomal operon is ranging from one copy to 20 copies in different bacterial phyla. Therefore, the number of 16S rRNA sequences quantified from soil DNA extracts does not give an exact estimate of the number of soil bacteria. Furthermore, the number of sequences is not necessarily linked to living microorganisms and can comprise sequences amplified from dead microorganisms.
