Foreword
Responding
LO
the
request of
the
US.
War Department, ASA Sectional Committee
1327
on
Standardization of Plain and Lock Washers was organized August, 1925, with
the
Society
of Automotive Engineers and The American Society of Mechanical Engineers
as
joint
sponsors. Since
1950
this committee has been known
as
Sectional Committee on Standard-
ization of Washers and Machine Rings.
,Subcommittee 1 on Plain Washers was appointed in May,
1928.
A
proposed standard
hubmitted by the subcommittee in October, 1932, was revised after CirculatiQn for criticism
.~nd comment.
A
second revision of the proposed standard was prepared and distributed in
\lay, 1935.
The
third and last revision of the proposal was referred to
the
sectional
corn-
,flittee
but did not receive
the
vote necessary for recommending
its
approval as an American
.Standard.
From 1937 until 1946 the Subcommittee
1
activity ‘was dormant, owing in part: to
industry preoccupation with
the
war effort and in part to sectional committee concentration
1)n
the
development of American Standards
for
lock
washers.,
-
there being some resistance
to
the concurrent development of both projects.
In 1346
the
Subcommittee
1
project was reactivated and in December of
that
year
a
new
I’roposal
for an American Standard was approved at
a
meeting of the sectional committee
,ubjcct to confirming approval by letter ballot vote of the sectionalrommitree..
As
the
Imposal
received an overwhelming vote of approval
in
the
letter ballot canvass, the sed
I
ic)nnl
committee at
a
meeting
in
December,
1948,
ordered its referral to
the
sponar
:.t~cicties.
It
was subsequently approved by the sponsor societies and by the American
.;r.lndards Association, and officially designated
as
an American Standard on August 31,
1
‘N.
U’hcn thc standard was brought up for triennial review it was decided
to
revise it
c.,litorially to include notes covering general applications, material, thickness, and defects
..ltich were inadvertently omitted from the
1949
original printing.
A
proposed revision dated
I
IllIe
1952, was approved by letter ballot vote
of
the
sectional committee, sponsors, and
,\lll~~il~~~n
Standards Association. Official designation as an American Standard (vas given
+.l.lrc.h
30,
1953;
Sl.lbsequcnt to publication of
the
1953 issue certain changes and inclusion of an
.,,l,li~it,mal scries
of
washers
were
proposed.
A.
proposed revision dated February 1356
.l,ppr~ved by letter ballot vote of the Sectional Committee sponsors and the American
~~bi~,];~~rds
Association. Official designation
as
an American Standard was given on August
3,
195H.

ASME B27.2-1965 是美国机械工程师协会（ASME）制定的一项关于弹簧垫圈（包括普通锁紧垫圈和锥形弹簧垫圈）的标准规范，该标准于1965年发布，主要规定了公制与英制尺寸弹簧垫圈的尺寸参数、材料要求、硬度、热处理及测试方法等内容，旨在确保此类紧固件在机械装配中的防松性能与可靠性。尽管当前已更新或部分被后续版本取代，该标准仍作为历史参考被广泛应用于工业设计、老设备维护及标准演化研究中，适合从事紧固件制造、机械设计及质量检验的专业人士查阅。
