11、r.No further reproduction or distribution is permitted.Uncontrolled when printed.FOREWORDThe American Society of Mechanical Engineers(ASME),recognizing the needs andbenefits associated with standard qualifications for professionals using the Y14.5 Standard,established the Y14.5.2 Subcommittee on Cer
12、tification in October 1988.The Subcommitteewas instructed to develop a standard that could be used as the basis of an ASME Programfor Certification of Geometric Dimensioning and Tolerancing Professionals(GDTP).Thisprogram provides the means to ensure proficiency in the understanding and application
13、ofthe geometric dimensioning and tolerancing principles expressed in Y14.5.Those principlesform an essential element of engineering language.This is a voluntary standard which sets forth the qualifications for two levels of certification.The first level,Technologist GDTP,provides a measure of an ind
14、ividuals ability tounderstand drawings which have been prepared using the language of Geometric Dimensioningand Tolerancing,as defined in the Y14.5 Standard.The second level,Senior GDTP,providesthe additional measure of an individuals ability to select and apply geometric controls todrawings.Primary
15、 changes to this revision are higher percentages of questions per section to increasethe applications emphasis on geometric dimensioning and tolerancing and the criteria forpassing the examination.ASME codes and standards are developed and maintained with the intent to representthe consensus of conc
16、erned interests.Revisions will be made periodically to the Standardto incorporate changes that appear necessary or desirable,as demonstrated by the experiencegained from the application of the requirements.Approved revisions will be publishedperiodically.The Committee welcomes proposals for revisions to this Standard.Such proposals shouldbe as specific as possible:citing the paragraph number(s),the proposed wording,and adetailed description of the reasons for the proposal.Correspondence should b
