20、 . 57Mandatory AppendixI 97ivFOREWORDThe development of this Standard was initiated at the request of industry and the government.A meeting was held to determine the interest in this subject in January 1997 in Wichita, Kansas,hosted by The Boeing Company in their facility. A subsequent meeting was h
21、eld during thespring ASME meeting in 1997 to enlist membership of those who would be interested in workingthis project.The Chairs of the different Y14 standards have been collaborating to improve the coordinationof the Y14 standards. To this end, in this revision of ASME Y14.41 material regarding Sa
22、vedViews is being move to ASME Y14.3. This material is retained in this publication of ASME Y14.41inMandatoryAppendixIasabaselineuntilsuchtimeasASMEY14.3ispublished.ThisAppendixwill be removed at a later revision of ASME Y14.41. Information on unequally or unilaterallydisposed profile tolerances has
23、 been removed from this standard since this information is nowincluded in ASME Y14.5-2009.The material in the standard was reorganized to locate all of the information on a topic togetherin the text. This allows the reader to find all of the requirements for a functional area in onelocation.A defini
24、tion of data set classifications was developed to describe the combinations of modeland drawinggraphics sheetsthat mightbe requiredby acustomer. Thismaterial isbeing includedin ASME Y14.100 as it has broader applicability than is appropriate for ASME Y14.41.Suggestions for improvement of this Standa
25、rd are welcome.
