26、gdrawingpracticesandtiestogethertheengineeringdraw-ing and related documentation practices in the ASME Y14 series of standards. It is not the intentof this Standard to be a standalone document for the purpose of addressing basic practices. Anaccurate perception of engineering drawing practices is de

27、rived by treating ASME Y14.100,ASME Y14.24, ASME Y14.34, ASME Y14.35, and ASME Y14.41 as a composite set.The initial attempt to convert the DoD drawing practices standard, MIL-STD-100, to a nongov-ernment standard resulted in two drawing practices standards: ASME Y14.100M-1998, whichconsisted of bas

28、ic practices common to DoD and industry, and MIL-STD-100G, which consistedof those practices and requirements unique to DoD. The impact on the community was thatjudgments on when to use which Standard as a standalone or in combination was causing agood deal of confusion. The consensus was that one s

29、tandard was needed. To accomplish this,this Standard contains appendices that may be invoked and tailored by DoD, thereby makingpossible the cancellation of MIL-STD-100.The revision of this Standard was initiated after the official release of ASME Y14.100-2013.Changes contained in this revision are

30、intended to improve standardization and harmonizepractices and methodology between industry and government.It is not the intent of this Standard to prevent individual organizations from designing specificdrawing practices that meet their individual needs, but rather to provide common engineeringdeli

31、neationstandardstoaidtheincreasinginterchangeofdrawingsbetweenindustry,government,and otherusers. When individualcompanies have detailedrequirements for theirspecific methodof operation, it shall be noted on the drawing or by tailoring the contract. Consequently, theminimum requirements set forth in

32、 this Standard will provide them flexibility in implementation.The appendices are intended for use by other than strictly commercial applications, such as DoD.However, nothing prevents commercial organizations from using the appendices and tailoringthem as necessary to meet their own needs.The succe

33、ssful revision of this Standard is attributed to the subcommittee members and theirrespective companies, and the departments and agencies of the U.S. Government.Suggestions for improvement of this Standard are welcome. They should be sent to TheAmerican Society of Mechanical Engineers; Attention: Se

CAGE Codes are listed in Cataloging Handbook H4/H8.3.12 Contractcontract: a mutually binding legal relationship obligating the seller to furnish the supplies or services, includi

It includes all types of commitments that obligate the procuring activityto an expenditure of appropriated funds and that, except as otherwise authorized, are in writing. In addition tobilateral instruments, contracts include, but are not limited to, awards
