Indian Standard
SPECIFICATION FOR
SMITH’S FULLERS
(First Revision)
0. FOREWORD
0.1 This Indian Standard ( First Revision ) was adopted by the Indian
Standards Institution on 11 January 1968, after the draft finalized by
the Hand Tools Sectional Committee had been approved by the Mechanical
Engineering Division Council.
0.2 This standard was originally issued in 1956. The presant revision
of the standard has been taken up to express the dimensional and
other requirements
only in metric units, rational&d
to the extent
practicable.
0.2.1 AdvantAge of this revision has been taken to reduce the number
of sixes in case of smith’s bottom fullers, small shank, and smith’s top fullers,
handle type from eight to seven.
0.3 This standard specifies the requirements
of the smith’s fullers:
a) Bottom, took form; and
of the following two forms
b) Top, tool form.
Roth these forms are used independently or in conjunction with each
other for the grooving and spreading hot iron.
0.4 It is recommended that the pur&aser should clearly specify in the
enquiry and order the requirements by refcrcnce to the type and sixe in this
standard.
0.5 While preparing this standard assistance has been derived from ~peci&
cation No. IND/GS/435
‘ Fullers, bottom and top ’ issued by Ministry of
Defence, Government of India.
0.6 For the purpose of deciding whether a particular requirement of
this standard is compliad with, the final value, observed or calculated,
expressing the result of a test, shall be rounded off in accordance
The number of sign&ant places retained in the rounded
with IS : 2-1960*.
off value should be the same as that of the specified value in this standard.

The f&crs may also be marked with the IS1 Certification Mark.
Nm - The use of the IS1 Certification Mark is verned by the provisions of
the Indian Standards Institution ( CertiScMion Mark ) Act and the Rules and
Re~l&one
made thereunder. The ISI Mark on products covered by an Indian
Stnndasd conveys the assurance that they have been produced to comply with the
re@rements of that standsrd under a well-detkmd system of inspection, testing and
quality control which is devised and supervised by IS1 and operated by the
producer. IS1 marked products are also continuously checked by ISI for conformity
to that standard as a further safeguard. Details of conditions under which a licence
for the USC of the IS1 Certification Mark may be
anted to manufacturers or
processora, may be obtained from the Indian Strrndu Jr Institution.

A-l.1 Lot -
In any consignment all the smith’s fullers of the same type
and size manufactured under essentially similar conditions of manufacture
shall constitute a lot.
A-I.2 For ascertaining the conformity of the lot to the requirements of
this specification, tests shall be carried out for each lot separately.
The
number of smith’s fullers to be selected at random for this purpose shall be
in accordance with co1 1 and 2 of Table 4.

AND
CONFORMITY
A-2.1 The smith’s fullers selected according to A-l.3 shall be examined
for hardness, shapes and dimensions, tolerances, and workmanship and
finish as specified in 3, 4, 5 and 8 respectively.
Any fuller failing to meet
the requirements
of any one or more of the characteristics
shall be
considered defective.
A-2.1.1 If the number of defective fullers in the sample is less than or
equal to the corresponding permissible number of defectives given in co1 3
of Table 4, the lot shall be declared conforming to the characteristics
mentioned in A-2.1.
A-2.2 From lots found satisfactory in accordance
with A-2.1.1,
a subsample of the size indicated in co1 4 of Table 4 shall be selected and
subjected to mechanical tests ( see 15 ).
A-2.2.1 If all the fullers subjected to mechanical
tests satisfy the
necessary
requirements,
the lot shall be declared conforming to the
