This document specifies a method using a barcoding system for tracing potential isolated defects that can be present in the following kinds of coated or uncoated steel flat products, for example: - electro-galvanised surface - galvanised surface - galvannealed surface - cold rolled surface This method, named “quality tracking”, aims at transferring additional material information to the steel users, especially the location of some isolated defects, in a reliable way. This method enables the manufacturer or purchaser to eliminate blanks or coils containing defects. The method uses a 1D barcode to identify each section of steel strip. NOTE 1 The stakeholders most involved in this technique are suppliers of steel flat products, car makers, appliance makers, part manufacturers, blanking line builders, steel processors, service centres, etc. All stakeholders can benefit from this project since defects can be traced, and, therefore, the steel containing defects can be eliminated or set apart of the production line. NOTE 2 In the first stages of development, this method was called "defect tracking" (see [1]) and has been changed into "quality tracking" at the beginning of the standardization process. NOTE 3 Quality tracking can be applied to other types of coated or uncoated steel flat products such as pickled and oiled, organic coated, and steels for packaging. Quality tracking can be applied for coiled materials for which the technology of quality tracking is applicable. NOTE 4 If quality tracking data are used outside of the purpose of quality tracking, it is under the responsibility of the user. NOTE 5 Quality tracking can be applied to other materials than steel. NOTE 6 The way to collect the information to be transferred to the user is out of the scope of this document.

This Part of prEN 10340, in addition to Part 1, specifies technical delivery conditions for steel castings for structural uses in buildings and civil engineering works. In cases where castings are joined by welding by the founder, this Part of prEN 10340 applies. This Part does not apply in cases where castings are welded: - to wrought products (plates, tubes, forgings...); or - by non-founders.

This document specifies product characteristic, test/assessment method and the way of expressing test results, for stainless steel as defined in EN 10088-1 and designated as in EN 10088-1 for the use of the reinforcement of concrete. It applies to stainless steel products with ribbed or indented surfaces, which are in the form of: - bars and coils (rod, wire); - sheets of factory-made machine-welded fabric; - lattice girders and hybrid lattice girders composed by stainless steel and by weldable reinforcing steel according to EN 10080. This document does not apply to: - pre-stressed stainless steels; - indented strip; - stainless steel tube filled with carbon steel swarf, which is then hot or cold reduced; - stainless steel smooth bar with weld material deposited on it; - galvanized reinforcing steel; - epoxy-coated reinforcing steel.

This document specifies the requirements for uncoated high strength steel strands or zinc or zinc alloy coated high strength steel strands, encapsulated with a protection product and a sheath 1). The intended use of these products is mainly the prestressing of concrete. NOTE These products can also be used in other stress applications in the construction field (e.g. stay cables for bridges) where the protection of the products is not removed in use. The standard applies only to products as supplied by the producer. 1) The word "sheath" used in the present document does not cover the sheaths as stated in mandate M/115 and specified in EN 523.
