16、8:2013(E)IntroductionThe use of ultrasound technology in condition monitoring is one of the key activities in predictive maintenance programmes for most industries. Other non-intrusive technologies including acoustic emission, infrared thermography, vibration analysis, lubricant analysis, wear debri

17、s 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

18、 programmes depends on the capabilities of individuals who perform the measurements and analyse the data. This part of ISO 18436 defines the requirements for personnel to become qualified to apply the non-intrusive machine condition monitoring and diagnostics technology of ultrasound.A programme, ad

19、ministered 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 diagnostics.This part of ISO 18436 defines the requirements against which personnel in t

20、he non-intrusive machinery condition monitoring and diagnostics technologies associated with ultrasound for machinery condition monitoring are qualified and the methods of assessing such personnel.iv ISO 2013 All rights reservedBS ISO 18436-8:2013Condition monitoring and diagnostics of machines Requ

22、is part of ISO 18436 provides recognition of the qualifications and competence of individuals to perform ultrasound measurements and analysis for machinery condition monitoring using ultrasound equipment. It is possible that this procedure is not applicable to specialized equipment or other specific

23、 situations.This part of ISO 18436 specifies a three-category classification programme that is based on the technical areas delineated herein, consistent with ISO 18436-1 and ISO 18436-3.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document a

They shall have demo

27、nstrated the necessary skills in ultrasound condition monitoring for their category as indicated in Annex A.Personnel classified as category II are required to have all the knowledge and skills expected of personnel classified as category I, while personnel classified as category III are required to

29、ing to established and recognized procedures. Personnel classified as category I shall be able to:a) apply a specified ultrasound measurement technique; however, persons classified as category I shall not be regarded as competent to choose the test method or technique used;b) set up and operate the

30、ultrasound equipment for safe ultrasound data collection;c) verify the integrity of collected data and prevent or control poor data and error sources;d) perform basic fault detection, severity assessment, and diagnosis in accordance with established instructions;e) record and categorize the results

31、in terms of written criteria;f) maintain a database of results and trends;g) verify sensitivity of ultrasound measurement instruments and systems;h) evaluate and report test results in accordance with instructions highlighting areas of concern;i) recognize and prevent or control factors that result

32、in the acquisition of poor quality data.4.3 Category IIIndividuals classified as category II are qualified to perform and/or direct ultrasound analysis according to established and recognized procedures, and are aware of the limitations of the ultrasound method.
