In view of the practical difficulties in inspecting a coil of wire rod along its entire length, it cannot be proved that no value greater than the specified limits is to be found in the coil as a whole. Statistical evaluation of performances applicable to all coils may be agreed between the purchaser and the manufacturer at the time of ordering. 7.2 Quality management system If agreed between the supplier and purchaser at the time of enquiry and order, the wire rod supplied shall be produced under a mutually acceptable quality system. 7.3 Form of delivery The delivery shall consist of one cast or a fraction thereof. Each product shall be traceable to the cast analysis, see Clause 11. 7.4 Delivery condition 7.4.1 Basic delivery condition Rod, bars and wire shall be supplied in one of the delivery conditions, that has been agreed at the time of ordering, as indicated in Table 1 of EN 10263-2:2017 and Tables 1 and 2 of EN 10263-3:2017 to EN 10263-5:2017. 7.4.2 Summary of combinations of delivery conditions, product forms and corresponding requirements A summary of customary delivery conditions and product forms and of the corresponding requirements concerning chemical composition, mechanical properties and, where applicable, hardenability is given in Table 1 of EN 10263-2:2017 and Tables 1 and 2 of EN 10263-3:2017 to EN 10263-5:2017. 7.4.3 Surface treatment Any surface treatment that can facilitate subsequent cold heading and cold extrusion or partially delay any formation of rust shall be subject of an agreement at the time of ordering. The above treatment can include, e.g. descaling, treatment with lime and-or phosphate. 7.5 Chemical composition 7.5.1 Cast analysis 7.5.1.1 The chemical composition of steel on cast analysis shall be in conformity with the values specified in Table 2 of EN 10263-2:2017, in Table 3 of EN 10263-3:2017, in Tables 3 and 4 of EN 10263 -4:2017
and in Table 3 of EN 10263-5:2017, as appropriate to the steel grade concerned. 7.5.1.2 In cases where steels for case hardening or for quenching and tempering are ordered in accordance with Tables 8 and 9 of EN 10263-3:2017 and in Tables 9 to 12 of EN 10263-4:2017, which SIST EN 10263-1:2018
EN 10263-1:2017 (E) 10 involves conformity with hardenability requirements according to the Jominy or core hardening tests, such hardenability requirements shall be considered as the governing criterion for acceptance. In such cases a deviation of the cast analysis with respect to the values indicated in Table 3 of EN 10263-3:2017 and in Tables 3 and 4 of EN 10263-4:2017 is admissible, taking into account the prescriptions given in footnote b) of those tables. In any case however, the deviations in the product analysis in relation to the specified limits of cast analysis shall not exceed the values indicated in Table 4 of EN 10263-3:2017 and in Table 5 of EN 10263-4:2017. 7.5.2 Product analysis The purchaser can specify at the time of enquiry and order that the chemical composition on product analysis be verified. In this case reference should be made to A.2. The permissible deviations in the product analysis in relation to the specified limits of cast analysis (see 7.5.1) are indicated in Table 3 of EN 10263-2:2017, in Table 4 of EN 10263-3:2017, in Table 5 of EN 10263-4:2017
and in Table 4 of EN 10263-5:2017. 7.6 Mechanical properties The mechanical properties of products covered by this European Standard shall meet the prescriptions stated in 6.3 of EN 10263-2:2017 to EN 10263-5:2017. 7.7 Hardenability requirements 7.7.1 General Products cannot be ordered and supplied according to both end quench test hardenability requirements and core hardening requirements 7.7.2 End quench (Jominy test) hardenability requirements In cases where a product is ordered with reference to a steel grade the designation of which is quoted in Tables 8 and 9 of EN 10263-3:2017
or in Tables 9 to 11 of EN 10263-4:2017, the product shall meet the hardenability requirements indicated in those tables. For the verification, see 10.2.1. 7.7.3 Core hardening requirements In cases where a product is ordered with reference to a steel grade the designation of which is quoted in Table 12 of EN 10263-4:2017, core hardening properties shall meet the requirements indicated in the relevant tables.

6 Production Process
Unless otherwise agreed at the time of enquiry and order, the production process is left to the discretion of the
manufacturer.
7 Requirements
7.1 General
Suppliers are responsible, using the means they think fit, for inspecting their product in accordance with
various quality criteria specified. In view of the practical difficulties in inspecting a coil of wire rod along its
entire length, it cannot be proved that no value greater than the specified limits is to be found in the coil as a
whole. Statistical evaluation of performances applicable to all coils may be agreed between the purchaser and
the manufacturer at the time of ordering.
7.2 Quality management system
If agreed between the supplier and purchaser at the time of enquiry and order, the wire rod supplied shall be
produced under a mutually acceptable quality system.
7.3 Form of delivery
The delivery shall consist of one cast or a fraction thereof. Each product shall be traceable to the cast
analysis, see clause 11.
7.4 Delivery condition
7.4.1 Basic delivery condition
Rod, bars and wire shall be supplied in one of the delivery conditions, that has been agreed at the time of
ordering, as indicated in Table 1 of prEN 10263-2:2013 and Tables 1 and 2 of prEN 10263-3:2013 to prEN
10263-5:2013.

7.4.2 Summary of combinations of delivery conditions, product forms and corresponding
requirements
A summary of customary delivery conditions and product forms and of the corresponding requirements
concerning chemical composition, mechanical properties and, where applicable, hardenability is given in
Table 1 of prEN 10263-2:2013 and Tables 1 and 2 of prEN 10263-3:2013 to prEN 10263-5:2013.
7.4.3 Surface treatment
Any surface treatment that can facilitate subsequent cold heading and cold extrusion or partially delay any
formation of rust shall be subject of an agreement at the time of ordering.
The above treatment can include, e.g., descaling, treatment with lime and-or phosphate.
7.5 Chemical composition
7.5.1 Cast analysis
7.5.1.1 The chemical composition of steel on cast analysis shall be in conformity with the values specified
in Table 2 of prEN 10263-2:2013, in Table 3 of prEN 10263-3:2013, in Tables 3 and 4 of prEN 10263-4:2013
and in Table 3 of prEN 10263-5:2013, as appropriate to the steel grade concerned.
7.5.1.2 In cases where steels for case hardening or for quenching and tempering are ordered in
accordance with Tables 8 and 9 of prEN 10263-3:2013 and in Tables 9 to 12 of prEN 10263-4:2013, which
involves conformity with hardenability requirements according to the Jominy or core hardening tests, such
hardenability requirements shall be considered as the governing criterion for acceptance.
In such cases a deviation of the cast analysis with respect to the values indicated in Table 3 of prEN 10263-
3:2013 and in Tables 3 and 4 of prEN 10263-4:2013 is admissible, taking into account the prescriptions given
in footnote b) of those tables. In any case however, the deviations in the product analysis in relation to the
specified limits of cast analysis shall not exceed the values indicated in Table 4 of prEN 10263-3:2013 and in
Table 5 of prEN 10263-4:2013.
7.5.2 Product analysis
The purchaser can specify at the time of enquiry and order that the chemical composition on product analysis
be verified. In this case reference should be made to A.2.
The permissible deviations in the product analysis in relation to the specified limits of cast analysis (see 7.5.1)
are indicated in Table 3 of prEN 10263-2:2013, in Table 4 of prEN 10263-3:2013, in Table 5 of
prEN 10263-4:2013 and in Table 4 of prEN 10263-5:2013.
7.6 Mechanical properties
The mechanical properties of products covered by this European Standard shall meet the prescriptions stated
in Clause 6.3 of prEN 10263-2:2013 to prEN 10263-5:2013.
