32、ents for qualification and assessment of personnel Part 2: Vibration condition monitoring and diagnostics IntroductionNon-intrusive technologies used in condition monitoring and fault diagnosis include vibration, infrared thermography, oil and wear debris analysis, acoustic and ultrasonic analysis,

33、and electric signature analysis.Those in manufacturing industry who have diligently and consistently applied these techniques have experienced a return on investment far exceeding their expectations. However, the effectiveness of these programmes depends on the capabilities of individuals who perfor

34、m the measurements and analyse the data.A programme, specified in this part of ISO 18436, has been developed to train and assess the competence of personnel whose duties require the appropriate theoretical and practical knowledge and relevant experience in VA for machinery condition monitoring and d

35、iagnostics.This part of ISO 18436 defines the requirements against which personnel associated with vibration measurement and analysis for machinery condition monitoring and diagnostics are to be assessed, and the methods of assessing such personnel. Applicants should be aware that employers and cust

36、omers are likely to have the greatest confidence in those vibration analysts certified by accredited bodies. Alternately, applicants can choose to seek recognition from other party assessment bodies which may provide the next lower level of confidence. Lastly, applicants may rely upon their own self

37、-assessment and declaration of competence but in doing so they should be aware that employers and customers are likely to have the least confidence in this option.7DIN ISO 18436-2:2014-111 ScopeThis part of ISO 18436 specifies requirements for the training, relevant experience, and examination of pe

38、rsonnel performing condition monitoring and diagnostics of machines using vibration analysis (VA).A certificate or declaration of conformity to the requirements of this part of ISO 18436 in accordance with ISO 18436-1, provides recognition and evidence that individuals are able to perform vibration

39、measurements and analysis for machinery condition monitoring and diagnostics using a range of vibration measurement equipment.This part of ISO 18436 specifies a four-category classification programme that is based on the technical areas delineated herein.2 Normative referencesThe following documents

42、ents for assessment bodies and the assessment process3 Terms and definitionsFor the purposes of this document, the terms and definitions given in ISO 1925, ISO 2041, ISO 13372, , and ISO 18436-1 apply.4 Classification of personnel4.1 GeneralDepending upon their competence in VA, individuals meeting

43、the requirements of this part of ISO 18436 shall be classified in one of four categories (4.2 to 4.5). They shall have demonstrated competence appropriate to their classification category as indicated in Annex A, in the concepts of machine condition monitoring using VA.The classification of individu

44、als at all categories shall be subject to the scope and any limitations of the award issued by the assessing body. Authority to work shall be limited or specified by the employer or 8DIN ISO 18436-2:2014-11client. Individuals shall provide recommendations based on the limits of their training and ex

45、perience. This declaration shall not allow a practitioner to make recommendations or give advice that may affect plant design, safety or operation without discussion with, and approval from, the appropriate plant specialist, manager or operator. The limits of the practitioner are specified in this c

46、lause whereas the limits of liability shall be agreed between the practitioner and their employer or client.The classification category of the practitioner and any requirements for additional knowledge to work with specific equipment shall be subject to agreement between the customer and service sup

47、plier. This qualification shall provide the practitioner with sufficient knowledge to be able to make measurements and interpret data as appropriate for their category. In addition, the applicability of the qualification to a particular specialized machine type or types should be verified by the cli

48、ent through reference to the previous experience and training of the practitioner. It is recognized that different industrial applications require knowledge of varying aspects of VA. Using supporting documented evidence, the supplier of the VA service shall be able to demonstrate to the employer or

49、client, that staff carrying out work has the appropriate machine knowledge and experience.Where an individual has specialized knowledge in a particular concept of VA or in specific types of machinery, they may be capable, when approved by the client or employer, of working beyond their qualification classification category.
