ECISS/TC 22 accepted this document at its meeting in February 1990. The following ECISS member bodies were represented at that meeting: Belgium, Finland, France, Germany, Italy, Norway, Sweden and United Kingdom.

In accordance with the CEN/CENELEC Internal Regulations, the following countries are bound to implement this European Standard:

Austria, Belgium, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and United Kingdom.

Foreword to EN 10207 : 1991/A1 : 1997

This Amendment to EN 10207 : 1991 has been prepared by Technical Committee ECISS/TC 22 'Steels for pressure purposes – Qualities', the Secretariat of which is held by DIN.

This Amendment shall be given the status of a national standard, either by publication of an identical text or by endorsement, and conflicting national standards withdrawn, by January 1998 at the latest.

In accordance with the CEN/CENELEC Internal Regulations, the following countries are bound to implement this European Standard:

Austria, Belgium, the Czech Republic, Denmark, Finland, France, Germany, Greece, Iceland, Ireland, Italy, Luxembourg, the Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, and the United Kingdom.

1 Scope

1.1 This European Standard has been established in order to provide complete technical delivery conditions for flat products and bars made of steel which are to comply with the specifications for pressurized parts in simple pressure vessels as defined in the Directive 87/404/EEC (see annex A) and standardized in EN 286-1.

1.2 The general technical delivery conditions specified in EN 10021 also apply to deliveries in accordance with this European Standard.

2 Normative references

This European Standard incorporates, by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications are listed

For the purposes of this standard, the following definitions apply in addition to those given in EN 10021, EN 10052, EN 10079 and EN 10204 (cf. clause 2).

4 Dimensions and tolerances on dimensions

The nominal dimensions and tolerances on dimensions for the product shall be agreed on ordering, with reference to the following dimensional standards:

4.1 In the case of hot rolled steel plate 3 mm thick or above, with reference to EN 10029, thickness tolerance class B.

4.2 In the case of

• continuously hot rolled wide strip (rolled width ≥ 600 mm),
• hot rolled slit strip in width < 600 mm, made of wide strip,
• hot rolled sheet in thicknesses under 3 mm,

with reference to EN 10051.

¹⁾ At present at the stage of draft. Until this document has been published as a European Standard, the corresponding national standard should be agreed upon at the time of ordering.
