Basic principles :

The ISO 9002 standard requires that the product carries a means of identification for the purpose of traceability of process characteristics and test results, at all stages of the production process that have a significant and planned effect on the product quality.

Means of identification - traceability :

Steel products

General points for each kind of product

labels
each unit (bundle, coil, spool) wears a label with at least following information

producer name

certification number of the producer

information about the certification/inspection body (name/number according to the future regulations)

plant

standard reference

reference number (cast, heat, batch....,see below for each kind of product)

traceability inside factory

Cast or heat number must allow to retrieve following information

processing parameters

hitches during process

results of performed tests

Hot rolling.

end products (i.e. hot rolled bars or wires).

The bars are marked so as to allow to retrieve following information :

name of the producer

steel grade.

hot rolled bars bundles.

The bundles wear labels with at least following information general information (see 2.1.1.1 above)

steel grade

nominal diameter

cast or heat number

Drawing, cold reducing, cold deforming, twisting and/or stretching.

End products (i.e. bars or wires)

The bars or wires are marked so as to allow to retrieve following information :

name of the producer

steel grade.

Bundles or coils

The bundles or coils wear labels with at least following information

general information (see 2.1.1.1 above)

steel grade

nominal diameter

cast or heat number

Traceability inside the manufacture for the products made from external acquired materials
besides information mentioned in 2.1.1.2, the coils origin and characteristics are to be traceable.

Remark : Bundles must not contain bars or wires from different casts or from different spools.

Fabric

Bundles

Each bundle wears one label with at least following information :

general information (see 2.1.1.1 above)

batch number

Traceability inside the factory

Reference number must allow to retrieve following information :

information mentioned in 2.1.1.2 above

welding machine

welding parameters

Prestressing strands or wires

Spools

Every spool wears labels with at least following information :

general information (see 2.1.1.1 above)

batch number allowing to retrieve the origin batch number of the wire or batch numbers of the wires that form part of the strand (steel grade, nominal diameter, type of surface)

strand or wire designation according to the standard (steel grade, nominal diameter, type of surface)

Traceability inside the factory

besides information mentioned in 2.1.1.2, following information is to be traceable.

numbers of the coils of the wires that form part of the strand and machine (strands)

drawing machine and drawing parameters (wires).

Decoiling, cutting and bending

Traceability outside the cutting and bending company.

Each order of similar cut and bent parts wears a label containing at least following information :

name of cutting and bending company

plant (building site)

identification of the certification/inspection body (c. and b. company)

batch number allowing to retrieve the origin heats of the bars that form part of the order

reference of the part

quantity of parts.

Traceability inside the c. and b. company

Order number must allow to retrieve following information :

reference number

references of parts included in the order/batch

quantity of parts of each reference

reference plans of each part

certification number of the steel producers

identification of cutting and bending machines

hitches occurred during the process

results of performed tests

steel producer.
