4 Designations
4.1 Material
4.1.1 General

The material is designated either by symbol or by number (see Table 1 and Table 2).

4.1.2 Symbols

The material symbol designation is based on the designation system given in ISO 1190-1.

NOTE Although material symbol designations used in this document can be the same as those in other

standards using the designation system given in ISO 1190-1, the detailed composition requirements are not

necessarily the same.
4.1.3 Number

The material number designation is in accordance with the system given in EN 1412.

4.2 Material condition

For the purposes of this document, the following designations, which are in accordance with the system

given in EN 1173, apply for the material condition:

D Material condition for the product as cold worked without specified mechanical properties;

H... Material condition designated by the minimum value of hardness requirement for the product

with mandatory hardness requirements;

R... Material condition designated by the minimum value of tensile strength requirement for the

product with mandatory tensile strength, 0,2 % proof strength and elongation requirements.

Products in the H... condition may be specified to Vickers or Brinell hardness. The material condition

designation H... is the same for both hardness test methods.

Exact conversion between the material conditions designated H... and R... is not possible.

Material condition is designated by only one of the above designations.

6.7 Form of delivery of profiled wire
Profiled wire shall be delivered in coiled form of the following types:

The products shall be clean and free from injurious defects, which shall be specified by agreement

between the purchaser and the supplier at the time of enquiry and order. A superficial film of residual

lubricant is normally present on cold worked products and is permissible unless otherwise specified.

Discolouration is permissible as long as it does not impair utilization.

Special requirements shall be agreed between the purchaser and the supplier [see Clause 5 list

entry m)] and shall then be indicated on the drawing as appropriate.
7 Sampling
7.1 General

When required (e.g. if necessary in accordance with specified procedures of a supplier's quality

management system, or when the purchaser requests inspection documents with test results, or for use

in cases of dispute), an inspection lot shall be sampled in accordance with 7.2 and 7.3.

7.2 Analysis

The sampling rate shall be in accordance with Table 14. A test sample, depending on the analytical

technique to be employed, shall be prepared from each sampling unit and used for the determination of

the composition.

When preparing the test sample, care should be taken to avoid contaminating or overheating. Carbide

tipped tools are recommended; steel tools, if used, should be made of magnetic material to assist in the

subsequent removal of extraneous iron. If the test samples are in finely divided form (e.g. drillings,

millings), they should be treated carefully with a strong magnet to remove any particles of iron

introduced during preparation.

In cases of dispute concerning the results of analysis, the full procedure given in ISO 1811-2 should be

followed.

Results may be used from analyses carried out at an earlier stage of manufacturing the product, e.g. at

the casting stage, if the material identity is maintained and if the quality management system of the

manufacturer is certified, e.g. as conforming to EN ISO 9001.

4 Designations
4.1 Material
4.1.1 General

The material is designated either by symbol or by number (see Table 1 and Table 2).

4.1.2 Symbols

The material symbol designation is based on the designation system given in ISO 1190-1.

NOTE Although material symbol designations used in this standard might be the same as those in other

standards using the designation system given in ISO 1190-1, the detailed composition requirements are not

necessarily the same.
4.1.3 Number

The material number designation is in accordance with the system given in EN 1412.

4.2 1Material condition

For the purposes of this standard, the following designations, which are in accordance with the system

given in EN 1173, apply for the material condition:

D Material condition for the product as drawn without specified mechanical properties;

H... Material condition designated by the minimum value of hardness requirement for the product

with mandatory hardness requirements;

R... Material condition designated by the minimum value of tensile strength requirement for the

product with mandatory tensile strength, 0,2 % proof strength and elongation requirements.

Products in the H... condition may be specified to Vickers or Brinell hardness. The material condition

designation H... is the same for both hardness test methods.

Exact conversion between the material conditions designated H... and R... is not possible.

Material condition is designated by only one of the above designations.
