ASME Y14.5.2:2000 pdf free download – CERTIFICATION OF GEOMETRIC DIMENSIONING AND TOLERANCING PROFESSIONALS
2.1 CERTIFICATION LEVELS
There shall be two (2) levels of GDTP Certification:
(a) Technologist
(b) Senior Certification at each level indicates that the individual has demonstrated competence in the areas described in subparas.
2.1.1 and 2.1.2.
2.1.1 Technologist Level.
Understanding the meaning of the symbols, modifiers, and relationships of Geometric Dimensioning and Tolerancing (GD& T) as applied to engineering drawings and related documentation.
2.1.2 Senior Level
(a) Understanding the meaning of the symbols, mod- ifiers, and relationships of GD&T as applied to engi- neering drawings and related documentation.
(b) Making the proper selection, with consideration for the function and relationship of part features, of geometric controls to document the product design intent.
(c) Performing calculations associated with GD&T. 2
(d) Applying the appropriate geometric control sym- bols, modifiers, and datum references to the engineering drawings and related documentation.
(e) Applying the principles of GD&T to the opera- tions of manufacturing, quality control, and verification processes associated with engineering drawings and related documentation.
(f) Applying the principles ofGD&T to the establish- ment of functional gaging activities.
2.2.1 Technologist GDTP.
The requirement for certification for a Technologist GDTP is to successfully pass the Technologist GDTP examination.
2.2.2 Senior GDTP.
The requirements for certifi- cation for a Senior GDTP are as follows: (a) five (5) years of documented experience in the field of GD&T in the recognized use of the system in both application and understanding; and (b) successfully passing the Senior GDTP examina- tion. Being a certified GDTP technologist is not required to qualify for taking the examination for Senior Level.
3.1 TECHNOLOGIST LEVEL EXAMINATION
The Technologist Level examination is a maximum of four hours in duration, consisting of 100 – 150 questions. The examination is a closed book, multiple choice, written examination, evaluating the applicant’s knowledge of GD&T principles, concepts, and practices in accordance with the current Y14.5 Standard. The topics are defined in the Technologist Level Body of Knowledge, Appendix A. The approximate distribution of questions is as follows:
(a) 10% on Scope, Definitions, and General Dimen- sioning
(b) 10% on General Tolerancing and Related Princi- ples and, Former Practices included in Y14.5, Appen- dix D
(c) 5% on Symbology
(d) 15% on Datum Referencing
(e) 30% on Tolerances of Location
(f) 30% on Tolerances of Form, Profile, Orientation, and Runout A candidate must achieve at least an 75% grade overall and score at least 50% in each of the preceding categories.
