Wires of less than 1mm diam. and
flat wires of less than 0.80mm
thickness and a maximum width of
5mm are delivered on plastic spools
according to DIN IEC 264 resp. on
American standard spools in
accordance with the tables on the
right.
Insulated wires are delivered on
plastic spools as for bare wires.
Stranded wires are delivered on
special spools holding up to 100kg
per spool in one length.
Ribbon with a maximum width of
10mm can be delivered on special
spools; ribbon of more than 10mm
width is delivered spirally wound in
the form of disks with an inner
diameter of 100mm and an outer
diameter of 300mm maximum.
Wires with a diameter of more than
1mm can be delivered on spools or
wound in coils as per the table on
the right.
Technical Terms of Delivery
For bare wires the terms of delivery
of DIN 46460, part 1, apply;
dimensions and resistance values
are standardized in DIN 46461 and
46463.
In general for linear resistance a
tolerance of ±5% from the nominal
value applies; this may increase to
±10% maximum for thin wires and
low resistance alloys. Within one
wire length the tolerance is appr.
±1% maximum from the actual
resistance per meter.
The wire diameter may deviate from
the nominal value by appr. ± 2.4%
maximum. For oxidized wires the
technical terms of delivery are
summarized in DIN 46464.
Wires insulated by an oxide layer
can be used at temperatures up to
the maximum working temperature

for bare wires. The break-down
voltage is more than 10V for
ISOTAN
®
and more than 3 V for the
nickel-chromium alloys ISA-
CHROM 80
®
and ISA-CHROM 60
®
.
For enamelled and silk-covered
wires the terms of delivery of DIN
46460, Parts 2 – 4, and DIN 46462
apply.
Enamelled wires are treated with a
so-called solderable enamel (DIN
designation Type V); the wires may
be directly tinned if the alloys
permits. On request a high-
temperature resistant enamel (DIN
designation Type W200), usable at
temperatures of up to 200°C, or
even more for short periods, is
available.

The break-down voltage for both
types ranges from 700 to more than
2.500V, depending on the diameter.
The wires can also be covered with
rayon, natural silk or glass fibre.
Subsequent impregnation with
silicone varnish for improved
adhesion is possible. The break-
down voltage is several hundred
volts.
