According to EA-04/15 the competence of personnel performing NDT should meet the requirements of testing standards / customer specifications / regulations, if any are specified, regardless of the form of employment. If not, the staff should have a valid certificate issued by an accredited certification body in accordance with EN ISO 9712 or an equivalent, and be authorized by the employer to certain activities in the field of certificate held. Supervision and monitoring should be performed by a person level 3 in each of the NDT methods used in the laboratory, through internal or external comparative testing. It specifies the minimum responsibilities of the supervisor.
Annexes A to E identified guidance on calibration and / or checking the measuring and testing equipment taking into account the requirements of the testing standards or own laboratory or customer’s specifications.
Annex F applies to the contents of the test procedure, and Annex G is the guidelines for internal audit.

Non-destructive testing of fiber-cement boards using time domain terahertz spectroscopy

Tomasz Chady, Krzysztof Schabowicz

The article proposes the use of NDT method utilizing electromagnetic waves with frequencies in the terahertz range for the inspection of fiber-cement boards. First, the most frequently appearing material defects in the plates, are presented. The measurements of defective and flawless plates were carried out using the terahertz method and the selected results are presented. The preliminary tests have confirmed the usefulness of the proposed method for testing fiber cement boards.

Probability of detection – the approach to combine probabilistic fracture mechanics with NDT – where we are ?

Gerd Dobmann

The contribution presents the detail discussion on various problematic aspects of utilization of both fracture mechanics based methodology and NDT technology to conduct the assessment of failure of components. Consequently, it shows a software tool concerning Probability of Detection – Probability of Sizing Concept, which allow to bring both methodologies (Fracture Mechanics and NDT) together and to meet in a joint approach. The contribution introduces in the application of one software approach, which allows modeling and simulation of real scenarios in detail, based on a variety of properties of different relevant materials from practice.

Progress in Digital Industrial Radiology. Part I: Radiographic Techniques – Film Replacement and Backscatter Imaging

Uwe Ewert

Similar to the success story of digital photography a major upheaval has been observed in digital industrial radiology. This paper is split into 3 parts:
Part 1: Film Replacement and Backscatter Imaging: Computed radiography with phosphor imaging plates substitutes film applications. Digital Detector Arrays enable an extraordinary increase of contrast sensitivity in comparison to film radiography. The increased sensitivity of digital detectors enables the efficient usage for dimensional measurements and functionality tests substituting manual maintenance. The digital measurement of wall thickness and corrosion status is state of the art in petrochemical industry. Photon counting and energy discriminating detectors are applied up to 300 kV and provide increased thickness dynamic and material discrimination by synchronously acquisition of images of the high and low energy part of the spectrum. X-ray back scatter techniques have been applied in safety and security relevant applications with single sided access of source and detector. First inspections of CFRP in aerospace industry were successfully conducted with newly designed back scatter cameras. Numeric modeling is used to design X-Ray optics and inspection scenarios as well as conducting RT training.
Part 2: Computed tomography (CT)
Part 3: Micro Radiography and Micro CT.

JOINING UP THE WORLD OF NDT – the role of ICNDT in a changing world

Mike Farley

ICNDT and its Regions provide a unique network for multilateral cooperation between NDT societies devoted to the development of the science and practice of NDT for the benefit of the public worldwide. As NDT, and the industries it serves, become more globalised, the need for international cooperation increases in priority and ICNDT and its Regions become more important. The individual member NDT Societies have vital roles to play and acting collectively have considerably more influence than if they act individually.

Assessment of residual life of ammonia reformers catalytic pipes by NDT test

Walenty Jasiński

The article presents the results of the stability of the microstructure and properties of catalytic cast pipes in steam reforming conditions. The growing prices of catalytic pipes have resulted in the attempts to prolong of the pipe work above 100,000 h stability. Increasing the time and temperature of operating causes coalescence and coagulation of secondary carbides reducing thus the creep resistance of the alloy. Currently there is no definite and commonly used method to assess the degree of degradation of the microstructure and properties of catalytic pipes. The destructive test methods of catalytic pipes are usually reduced to the assessment of the effects of metallographic creeping process, ie. relative volume and distribution of mikrovoids on the pipe wall section, as well as evaluating the mechanical properties of steel. These methods generally give a clear assessment but require disassembly for testing pipes and replace ment with new ones. The author developed the regression which show a significant dependence of mechanical properties (Rm A5, KCU 2) on the operating parameters of the reformer (PLM, σ) and hardness HB cast IN 519. The equations have been applied to assess the possibility of using non-destructive testing for the assessment of the degree of degradation of the catalyst steel pipe.

A strategic overview of Non-Destructive Testing according to the European Federation of NDT

Roger Lyon

The current structure for the International Committee for NDT and the Regional groups which include the European Federation of NDT established in the 1990s is presented. EFNDT has proposed a reorganisation of the ICNDT/Regional Federations, with clearer definitions as to what is to be done at each level and stronger coordination. In order to promote fairness and safety in Europe, it is essential that each EFNDT Member society makes a commitment to uphold and promote the principles of the EFNDT Code of Ethics and in doing so, we will create a greater level of trust and confidence, and a positive perception of the non-destructive testing profession. EFNDT is currently managed by a President, Vice President and eight other Board of Directors who are democratically elected at the EFNDT General Assembly. It is essential however, that the Board of Directors and the other 22 member societies and 7 associate members communicate effectively in order to develop a harmonised approach to the provision of NDT products and services. In terms of normalisation, EFNDT’s key process is the Multilateral Recognition Agreement (MRA), which promotes harmonisation of the personnel. Certification schemes operated by Certification Bodies and nominated by the national NDT societies facilitate worldwide recognition and acceptance of certificates of competence. Cooperation of NDT Companies across European countries will promote global harmonisation and will facilitate the sharing of knowledge and skills to mutual benefit. Education and training are also key components of international cooperation and harmonisation; EFNDT are currently considering creating documents about the requirements for training centres and defining the levels of excellence. The United Kingdom has undergone a transformation in terms of delivering Apprenticeships, in particular NDT Apprenticeships. EFNDT are considering the possibility of a European apprenticeship scheme framework for NDT. The NDT personnel in Europe have a responsibility to promote NDT as a key Engineering skill which helps to reduce risk, operate safely and save lives.

Use of water immersion UT techniques to assist with data capture

Neil R. Pearson, Steven Marshall, Wayne Woodhead, Alan Ashton, Radosław Boba

Ascertaining the integrity of large steel structures such as storage tanks, pipes and vessels is a complex task. Silverwing (UK) Ltd have developed an inspection system based on a water immersion UT (ultrasonic testing) approach that can manage, present and generate reports for large volumes of data, from gigabytes to even terabytes that can be obtained from a single asset. This paper explores inspection efficiency at the data capture stage and shows examples towards illustrating how volumes of information is technically handled and how it can improve the efficiency of the overall inspection process, benefiting the inspection company, asset integrity engineer and asset owner.
