Overview

EN 10140:2006 is a CEN European Standard that defines tolerances on dimensions and shape for cold rolled narrow steel strip supplied in coils or cut lengths. It applies to unalloyed and alloyed steels (excluding stainless and heat‑resisting grades) with thicknesses up to 10 mm and widths less than 600 mm (extension to 650 mm by agreement). The standard establishes delivery forms, designation rules, measurement methods and packing requirements to ensure consistent dimensional quality for cold‑rolled narrow strip.

Key topics and technical requirements

  • Scope & exclusions: Covers narrow strip made from steels referenced in EN 10132, EN 10139, EN 10268 and prEN 10338; excludes products covered by separate standards (e.g., EN 10106, EN 10107, EN 10341, EN 10131, EN 10205).
  • Form of delivery: Supplied in coils (preferred internal diameters ~500 mm or 400 mm) or cut lengths; very narrow strip may be bobbin wound.
  • Designation: Standardized product designation includes product type, EN reference, nominal thickness and width, edge type, tolerance class and steel grade.
  • Tolerances on thickness: Three classes - A (normal), B (fine) and C (precision). Specific numeric tolerances are provided in tabulated form (Table 1) for nominal thicknesses from 0.10 mm to 10.00 mm and depend on nominal width.
  • Tolerances on width: Dependent on edge condition (as‑rolled, slit or special) and nominal width. Separate tables define permissible plus/minus ranges for as‑rolled and slit edges.
  • Length tolerances: Cut lengths are supplied with defined plus tolerances that vary with nominal length and tolerance class (A or B).
  • Shape tolerances:
    • Edge camber: Measured over a 1 000 mm gauge length; Class A and Class B limits are given in a table.
    • Flatness: Default maximum deviation 10 mm over 1 000 mm in rolling direction unless otherwise agreed.
    • Out‑of‑squareness: ≤ 1 mm for widths ≤ 100 mm; ≤ 1% of width for greater widths.
  • Measurement rules: Minimum distances from edges for thickness measurement and defined gauge lengths for flatness and camber (usually 1 000 mm).
  • Packing: Coils must be secured to avoid damage or unwinding during handling and transport.

Applications and users

EN 10140 is used by:

  • Steel producers and slitters to specify and verify product quality.
  • Purchasing and procurement teams specifying narrow strip for cold forming, stamping or finishing.
  • Quality control, inspection and testing laboratories for dimensional acceptance criteria.
  • OEMs in automotive, white goods, electrical components, and general engineering that require consistent narrow strip geometry for downstream processing.

Practical benefits include reduced scrap, improved interchangeability, clear contractual specifications and consistent manufacturing tolerances.
