11、ation of Technical Committee 20 on the Standardization of Reamers in March 1937 was prompted by a recognized need for unifying the practice in this field.The proposal submitted by the committee was approved by ASA and designated ASA B5.14-1941.The Standard ASA B5.14-1941 was revised and approved in
12、1949,and sub-sequently reaffirmed in 1954.A sufficient number of requests for revision resulted in reactivation of the committee in 1957.The revision was approved by the sectional com-mittee and the sponsors,and the required ASA approval and designation were granted April 9,1959.In November 1961,the
13、 ASA Mechanical Standards Board approved the request of the B5 Sectional Committee sponsors that a separate project be initiated under ASA Procedure on the subject of Cutting Tools.As a result of this action,a new project was initiated on Cutting Tools,and ASME accepted sponsorship.The committee was
14、 designated B94 Cutting Tools,and the activity on cutting tools was removed from the B5 Sectional Committee.The designation numbers of the technical committees were changed to con-form with the new sectional committee organization.B5 Technical Committee 20 was changed to B94 Technical Committee 9.Re
15、quests for revision to B5.14-1959 to cover additions,deletions,and clarification of the Standard necessitated reactivation of the committee.The revised draft was prepared and distributed to the members for review and comment.A meeting of TC-9 was held in November 1962,and the draft was subsequently
16、approved by the committee.The revised Standard was submitted to Sectional Committee B94 on May 27,1964.Following approval by the Sectional Committee and the sponsor,the Standard was ap-proved by ASA on December 21,1964 and designated as ASA B94.2-1964.In 1970,Technical Committee 9 revised the 1964 issue of B94.2,incorporating revisions and additions reflecting current industry practice.The revision was presented to American National Standards Committee B94 and to the B94 secretariat for approval
