AMENDED, published in the IUS N 8, 2015

An amendment made by the manufacturer of the database

1 Scope

This standard specifies the tolerances on diameter of round steel wire: bright (uncoated) steel wire, steel wire with a metallic coating steel wire with non-metallic coating, and, where necessary, on a length of round wire cut to a certain measuring length.

2 Normative references

This standard uses the regulatory references to the following standards:

ISO 6929 steel Products. Definitions and classification

3 Terms and definitions

This standard uses the following terms with respective definitions:

3.1 wire (wire): according to ISO 6929.

Note: Wire can be supplied with a metallic coating, nonmetallic coating, with two kinds of coatings, without coating.

3.2 cut length (cut length): straight-cutting wire cut to a certain length.

4 Tolerances on diameter of wire

4.1 General provisions

Diameter measurement can be performed at any cross section of the wire and must not exceed the tolerances set out in the relevant tables of this standard.

Note:

1 Tolerances on diameter can change, if the segments lengths are supplied by a third party.

2 diameter Tolerances of classes from to (see Table 1) are calculated as follows:

; ; ; ; ,

where is the measured diameter in millimeters.

4.2 the Tolerances on diameter of round steel wires uncoated and zinc-coated

The desired range of tolerances in Table 1 must be specified in the document for the product or provider of a wire in the order/request.

The diameter must be within tolerance range shown in Table 1.

Note — If the order/request or in the document to the product, unless otherwise stated, the tolerance class of normally used for galvanized wire with a thick layer (A), class is usually used for galvanized wire, and class , and for the light of cold drawn wire with higher order, depending on the required accuracy.


Table 1 — Tolerances for diameter

4.3 Ovality

Ovality is defined as the difference between the maximum and minimum wire diameter in any cross section. Ovality shall not be more than half the total tolerance given in Table 1.

4.4 Tolerances on diameter of wire with organic coating

4.4.1 Organic coating applied by extrusion

The tolerances on the wire diameter with coating by extrusion are shown in Table 2. The electrode wire can be bright or covered in metal (usually galvanized).

4.4.2 Organic coatings, applied by sintering

The tolerances on the wire diameter with coating sintering method are shown in Table 2. Typically, the electrode wire has a metal coating (usually galvanized).


Table 2 — Tolerances for diameter of wire and thickness of organic coatings applied by sintering and extrusion

5 Tolerances on the segments lengths

5.1 the Tolerances on length

Tolerances on the length of the segments lengths shall conform to the requirements of Table 3.

Table 3 shows three classes of tolerances for length of segments length, dependent on nominal length. The supplier shall select the appropriate class.


Table 3 — Tolerances on length of segments lengths

5.2 Tolerances on straightness

Table 4 shows the three classes of straight segment lengths, for the diameter wire installed in Table 5. The supplier shall select the appropriate class. Figure 1 illustrates the measurement of deviation from straightness.


Table 4 — Tolerances on straightness of the segments lengths

Table 5 — Length of test for measurement of deviation from straightness

Figure 1 — Measurement of deviation from straightness

Designation:  — measured length deviation from straightness

Figure 1 — Measurement of deviation from straightness

For class 1 and class 2 segments lengths shall conform to the requirements of the tests for clotting, which is performed on a glass smooth inclined plane. Segments lengths is placed on an inclined plane in a position that allows them the freedom to curl up, drifting down.

6 Length of wire in the rebellion

Knowing the size and density of the wire, its length in a riot can be determined by weighing the rebellion and calculate the length on the ground.
