27、 Addenda 135-189 ASME B18.27.4 Added FOREWORD American National Standards Committee B27 for the standardization of plain and lock washers was organized in March 1926 as Sectional Committee B27, under the aegis of the American Stand;irds Association (later the United States of America Standards Insti

28、tute and, as of October q, 1969, the American National Standards Institute, Inc.), with the Society of Automotive ;Engineers and The American Society of Mechanical Engineers as joint secretariats. In 950, this Committee was designated as responsible for the standardization of washers and 1machine ri

29、ngs. At a meeting; of ANSI B27 Standards Committee held on February 4, 1971, it was recommended to the secretariats (ASME and SAE) that Subcommittees l, 2, and 4 on Washers be merged into ANSI Bl8 Standards Committee and that Subcommittee 3 on Retaining Rings become a separate Standards Committee re

30、taining the B27 designation. This change was subsequently approved by ANSI. Formation of Subcommittee 1 on Tapered and Reduced Section Retaining Rings was authorized by Standards Committee B27 at its meeting on October 15, 1974. At this meeting, it was decided that no further effort should be expend

31、ed on inch dimensional products and Subcommittee 1 was assigned the responsibility of preparing American metric standards for tapered and reduced section retaining rings. Subcommittee 1 prepared a draft proposal, General Purpose Tapered and Reduced Cross Section Retaining Rings, which was balloted o

32、n June 16, 1975. At a subcommittee meeting held on February 17, 1976, results from the letter ballot were reviewed. The proposal was accepted by the Subcommittee and presented to the B27 Standards Committee at its May 7, 1976, meeting. At that meeting, a Jetter ballot of the entire committee was aut

33、horized. The Standard was duly approved by the Committee and its sponsors and submitted to the American National Standards Institute for designation as an American Standard. This designation was granted on October 20, 1977. It was recommended that American National Standards Committee B27 be made pa

34、rt of ASME B18 Main Committee. As a result, Subcommittee 27 of ASME Bl8 has the responsibility of developing and maintaining standards for retaining rings. A need evolved for commercial and military requirements to develop inch series standards for General Purpose Tapered and Reduced Cross Section T

35、ype Retaining Rings. It was agreed by the ASME B 18 Main Committee to have Subcommittee 27 develop these required inch series standards. The first of the inch standards, B 18.27 .1, covering External Type NAI, Internal Type NA2, and E-Ring Type NA3 rings, was approved by ANSI on July 16, 1998. The s

36、econd of the inch standards, B18.27.2, covering Heavy Duty External Type NA4, Reinforced E-Rings NA5, and C-Rings Type NA6, was approved by ANSI on July 16, 1998. The third of the inch standards, B 18.27 .3, covering Bowed External Rings NA 7, Bowed Internal Rings NA8, and Bowed External E-Rings NA9

37、, was approved by ANSI on July 16, 1998. The fourth of the inch standards, B 18.27.4, covering Inverted External Rings NA 10, Inverted Internal Rings NA! 1, Beveled External Rings NAI2, and Beveled Internal Rings NA13, was approved by ANSI on May 10, 1999. iii (a) (bl The fifth and final of the inch

38、 standards, Bl8.27.5, covering External Self-Locking Rings Type NA14, External Interlocking Rings Type NAl5, and External Bowed Locking Prongs Rings NA 16, was approved by ANSI on February 11, 2000. iv ASME 818 STANDARDS COMMITTEE Standardization of Bolts, Nuts, Rivets, Screws, Washers, and Similar
