SPECIFICATION FOR
FLOOR DOOR STOPPERS
( Third Revision )
0. FOREWORD
0.1 This Indian Standard ( Third Revision) was adopted by the Indian
Standards Institution- on 24 January 1980, after the draft finalized by
the Builders Hardware Sectional Committee had been approved by the
Civil Engineering Division Council.
0.2 The specification for floor door stoppers was first published in 1962 and
revised in 1968, and the second revision was issued in 1974. In the third
revision the improvement made by the industry in the manufacture of floor
door stoppers have been incorporated. To satisfy the functional require-
ments better certain dimensions have .been kept binding, and certain
new dimensions have been introduced to ensure interchangeability. Some
new material for the manufactureof body and cover plate have also been
introduced.
0.3 For the purpose of deciding whether a particular requirement of
this standard is complied with, the final value, observed or calculated,
expressing the result of a test or analysis, shall. be rounded off in
accordance with IS : 2-1960*. The number of significant places retained in
the rounded off value should be the same as that of the specified value
in this standard.
1. SCOPE.
1.1 This standard lays down the requirements for floor door stopper
suitable for use with .door &utters of 30, 35, 40 and 45 mm thickness.
2. MATERIALS
2.1 Materials used for the manufacture of various components of floor
door stiipv s shall conform to those given in Table ,l.

A-l.1 Lot-In any consignment all the ffoor door stoppers of same shape,
size and manufactured from similar. materials under identical condition
shall be grouped together to constitute a lot.
A-1.2 The number of floor door stoppers to be selected from a lot
shall depend on the size of the lot and shall be in accordance with co1 1
and 2 of Table 4.
