Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.

Introduction
The use of acoustic emission technology in condition monitoring is one of the key activities in
predictive maintenance programmes for most industries. Other non-intrusive technologies including
infrared thermography, vibration analysis, lubricant analysis, wear debris analysis and motor current
analysis are used as complementary condition analysis tools. Those in the manufacturing industry who
have diligently and consistently applied these technologies have experienced a return on investment
far exceeding their expectations. However, the effectiveness of these programmes depends on the
capabilities of individuals who perform the measurements and analyse the data.
A programme, administered by an assessment body, has been developed to train and assess the
competence of personnel whose duties require the appropriate theoretical and practical knowledge of
machinery condition monitoring and diagnostic techniques.
This document defines the requirements against which personnel using non-intrusive machinery
condition monitoring and diagnostics technologies associated with acoustic emission for machinery
condition monitoring are to be qualified and the methods of assessing such personnel.
