ASME Y14.5.2:2017 pdf download.Certification of Geometric Dimensioning and Tolerancing Professionals
1.1 Scope This Standard establishes certification requirements for a geometric dimensioning and tolerancing profes- sional (GDTP). Certification shall be based on either ASME Y14.5M-1994 or ASME Y14.5-2009, its appendices, and the application of its principles and concepts. 1.2 Purpose ThisStandardprovidesrequirementsandqualifications to be used in certifying a GDTP. These requirements and qualifications recognize the knowledge, training, and experience necessary to understand, apply, and teach the principles as set forth in ASME Y14.5M-1994 or ASME Y14.5-2009. A GDTP may be employed as, but is not limited to (a) design engineer (b) production or manufacturing engineer (c) process engineer (d) quality engineer (e) tool or gage engineer (f) engineering manager (g) user or programmer of CAD, CAM, CAE, or other software (h) drafter (i) checker (j) engineering consultant (k) educator (l) inspector (m) contract engineer (n) project engineer (o) technical specialist
2 CERTIFICATION LEVELS AND QUALIFICATIONS
2.1 Certification Levels There shall be two levels of GDTP certification: (a) Technologist (b) Senior Certification indicates that the individual has demon- strated competence in the areas described in para. 2.1.1, 2.1.2, 2.1.3, or 2.1.4. 2.1.1 Technologist Level (ASME Y14.5M-1994 Examination). Certification indicates that the individual has demonstrated an understandingofthe meaningofthe symbols,modifiers,andrelationships ofgeometricdimen- sioning and tolerancing (GD&T) as applied to engineering drawings and related documentation that conform to ASME Y14.5M-1994. 2.1.2 Technologist Level (ASME Y14.5-2009 Examination). Certification indicates that the individual has demonstrated competencies in reading and inter- preting an engineering drawing that conforms to ASME Y14.5-2009. These include, but are not limited to, the following: (a) understandingtherules,definitions,principles,and meaningsofthesymbolsandmodifiersofGD&Tasapplied to engineering drawings and related documentation (b) understanding the functions and relationships of part features and geometric controls (c) performing calculations associated with GD&T derived from the drawing and related documentation (d) understanding that the application of GD&T has implications for manufacturing, quality control, and veri- fication processes associated with engineering drawings and related documentation (e) applying the principles of GD&T to the establish- ment of functional gaging activities 2.1.3 SeniorLevel(ASMEY14.5M-1994Examination). Certification indicates that the individual has demon- strated competencies in application ofthe rules and prin- ciples required to generate an engineering drawing that conforms to ASME Y14.5M-1994. These include, but are not limited to, the following:(a) understanding the meaning of the symbols, modi- fiers, and relationships ofGD&T as applied to engineering drawings and related documentation that conform to ASME Y14.5M-1994 (b) makingthe properselection, with considerationfor thefunctionandrelationship ofpartfeatures,ofgeometric controls to document the product design intent (c) applying the appropriate geometric control symbols, modifiers, and datum references to the engi- neering drawings and related documentation (d) applyingtheprinciplesofGD&Ttotheoperationsof manufacturing, qualitycontrol, and verification processes associated with engineering drawings and related documentation (e) applying the principles of GD&T to the establish- ment of functional gaging activities 2.1.4 Senior Level (ASME Y14.5-2009 Examination). Certification indicates that the individual has demon- strated competencies in the application of the rules and principles required to generate an engineering drawing that conforms to ASME Y14.5-2009. These include, but are not limited to, the following: (a) understandingtherules,definitions,principles,and meaningsofthesymbolsandmodifiersofGD&Tasapplied to engineering drawings and related documentation (b) making the proper selection with consideration for the function and relationship of part features and geometriccontrols,to documenttheproductdesignintent (c) performing calculations associated with GD&T to determine the geometric requirements (d) applying the appropriate geometric control symbols, modifiers, and datum references to the engi- neering drawings and related documentation (e) applyingtheprinciples ofGD&Tto theoperations of manufacturing, qualitycontrol, and verification processes associated with engineering drawings and related documentation (f) applying the principles of GD&T to the establish- ment of functional gaging activities
