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)
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 :
