G 8532 : 2011

Foreword
This translation has been made based on the original Japanese Industrial Standard revised by the Minister of Economy, Trade and Industry
through deliberations at the Japanese Industrial Standards Committee
as the result of proposal for revision of Japanese Industrial Standard
submitted by Japan Wire Products Association (JWPA) with the draft
being attached, based on the provision of Article 12 Clause 1 of the Industrial Standardization Law applicable to the case of revision by the
provision of Article 14.
Consequently JIS G 3582 : 2000 is replaced with this Standard.
However, JIS G 3532 : 2000 may be applied in the JIS mark certification based on the relevant provisions of Article 19 Clause 1, etc. of the
Industrial Standardization Law until August 20th, 2011.

This JIS document is protected by the Copyright Law.
Attention is drawn to the possibility that some parts of this Standard
may conflict with a patent right, application for a patent after opening
to the public or utility model right. The relevant Minister and the
Japanese Industrial Standards Committee are not responsible for
identifying the patent right, application for a patent after opening to
the public, or utility model right.

As for the wires marked with a slash in this table, there is no
prescription since no wire is produced.

Shape of deformed low carbon steel wires

As to the shape, the deformed low carbon steel wires shall have two or more rows of
protrusions or indentations oriented regularly on the surface, and further meet the fol-

lowing specifications.
a)


The ribbed wires shall conform to the following conditions.
1)

The ribbed wires shall have two or more rows of transverse ribs equally distributed around the perimeter with a substantially uniform rib spacing not greater
than 0.8 x d (dis the nominal diameter). However, as for rib spacing, Annex JA
may be applied under the agreement between the manufacturer and the purchaser.

Rib height and rib inclination of deformed low carbon steel wires

As for rib height and rib inclination, Annex JA may be applied under the agreement between the manufacturer and the purchaser.

Surface conditions

The wire of SWM-F shall be free from. residual film 2 or adhered matters on the surface which will be detrimental to the post-coating or welding.
Note?
10

The film of lubricant used for cold-working being on the surface of the wire.

Appedrance

Appearance are visually confirmed, and the surface of the wire shall be free from
such defects as rust, flaw and crack that are detrimental to practical use. For the wire
SWM.-A of annealed quality, however, requirements for mill scale may not be applied.

Test
Sampling method of test pieces

PROTECTED

BY COPYRIGHT


11
G 8532 : 2011
The sampling method of test pieces shall be as given in the following.
a)


Each one of the test pieces for tensile test, bend test and torsion test shall be taken
respectively from one end of coil representing the lot produced under the same condition.
NOTE:

The lot produced under the same condition means the material produced
of steel wire by the same fabricating condition from the same type sym-

bol of wire rod.
b)

The test piece shall be No. 9 test piece (type 9A or 9B) of Annex C or Annex D of JIS

Z 2241.

11.2

Tensile test

The tensile test shall be as given in the following.
a)

The test method shall be as specified in JIS Z 2241.

b)

The gauge length to determine the elongation for the cold-reduced steel wire for the
reinforcement of concrete and the manufacture of welded fabric shall be 5 times the

diameter or the nominal wire diameter regardless of the requirements of 11.1 b).


c)

When the test piece for tensile testing fractures at a gripped potion, the test shall be
invalidated, and a retest may be carried out on the test piece newly taken from the
same coil.

11.3

Bend test

As to the bend test for the cold-reduced steel wire for the reinforcement of concrete
and the manufacture of welded fabric, the test piece shall be bent to an angle between

160°

and

180° around

a cylinder or roller by suitable means.

The

diameter

of the

cylinder or rollergt
11.4


Torsion test

The torsion test shall be as given in the following.
a)

The wires to be subjected to the test shall be straightened by hand or with a wooden
hammer, etc., and then cut to approximately 300 mm in length for use as the test
piece.

b)

As to the test method, both ends of the test piece shall be gripped firmly at an interval of 200.mm, and one gripped end shall be turned up to the specified number given
in table 2 while giving tension enough to prevent it from sagging.

c)

In the case where the test piece fractures at a gripped portion in testing and the
cause of this phenomenon is obviously the inappropriate testing operation, the test
shall be invalidated, and a retest may be carried out on the test piece newly taken
from the same coil.

11.5

Measurement of wire diameter for plain wires

The wire diameter for plain wire shall be determined by measuring the maximum
diameter and the minimum one on the same cross section at as arbitrary part.
11.6
The

Inspection
The inspection shall be carried out as follows.

a)


The mechanical properties shali conform to the requirements specified in clause 7.

b)

The wire diameter or nominal wire diameter, nominal cross-sectional area and mass
per unit length shall conform to the requirements specified in clause 8.

c)

The surface conditions shall conform to the requirements specified in clause 9.

d)

The appearance shall conform to the requirements specified in clause 10.
