EN 10218-2-2012 pdf download.Steel wire and wire products-General – Part 2 : Wire dimensions and tolerances.
This EN 10218-2 specifies the tolerances on diameter of round wire and , where applicable , on the
wire cut to length , for bright steel wire , ( i.e. uncoated ) , metallic coated steel wire and non –
metallic
This European Standard should not be applied where other requirements for dimensions and tolerances are
specified in a particular product standard
2 Normative references
The following referenced documents are indispensable for the application of this document . For dated
eferences , only the edition cited applies . For undated references , the latest edition of the referenced
document ( including any amendments ) applies
EN 10079 : 2007 , Definition of stee / product
3 Terms and definitions
For the purposes of this document , the following terms and definitions apply
wire
product of constant full cross section along its length , obtained by cold drawing rod through a reducing die or
assing under pressure between rollers and rewinding the drawn product
NOTE 1 The cross section is generally round , though sometimes oval , rectangular , square , hexagonal , octagonal or
other convex section .
propertes wire may be sued uncoated as an annese or co ted e w nc co , niea o pastic
NOTE 3 Heat treatments and / or surface treatments may be carried out during the course of manufacture to improve
the properties of wire
EN 10079 : 2007
NOTE 4 As well as being supplied in the uncoated ( gh ) condition wire can also be supplied with metallic or non –
metallic coatings or both . The metallic coating can be as a finished coating or as a drawn finished coating
3.2
cut length
straightened piece of wire cut to a specified length
The purchaser or the product standard shall indicate the tolerance range required from Table 1
The overall diameter shall be within the relevant tolerance range given in Table 1 ; the producer will adapt
rocessing parameters to ensure compliance with the required properties of the wire in the respective product
standard , taking into account the influence of the coating thickness ( if applicable )
NOTE 3 Unless otherwise specified on the order enquiry or the product standard , tolerances class T1 would generally
be used for heavy galvanised ( A ) wire , T2 would generally be used for other galvanised wire . and T3 , T4 and T5 would
generally be used for bright drawn wire in increasing order of precision required
EN 10218-2 : 2012 ( E )
4.1.2 Out of roundness ( ovality )
The out of roundness is the difference between maximum and minimum diameter of the wire at any cross –
section and shall not be more than one half of the total tolerance given in Table 1
For diameters d from 0.050 mm to 25,00 mm , the tolerances on diameter shall be as follows :
4.2.2 Extruded organic coating
Tolerances on diameter of extruded organic coated wire are given in Table 2
The core wire can be either bright or metallic coated ( usually zinc )
4.2.3 Sintered organic coating
The tolerances on diameter of sintered organic coated wire are given in Table 2 . Generally , the core wire is
metallic coated ( usually zinc coated ).EN 10218-2-2012 pdf download.
