SIST EN ISO 16120-1:2017 PDF

Overview

EN ISO 16120-1:2017 - Non-alloy steel wire rod for conversion to wire - Part 1: General requirements - defines the general requirements for non-alloy steel wire rod intended for subsequent wire drawing and/or cold rolling. The standard covers wire rod with a variety of cross-sections (circular, oval, square, rectangular, hexagonal, octagonal, half‑round or other shapes) generally having a nominal dimension of at least 5 mm and a smooth surface. It establishes baseline specifications for production, inspection, delivery and documentation, while excluding specialized wire rod products covered by other standards.

Key Topics

• Scope & applicability: General-purpose non-alloy wire rod for conversion to wire; explicitly excludes items with separate standards (e.g., wire rod for heat treatment, free‑cutting grades, cold heading/extrusion, welding electrodes, reinforcement fabric, bearing steels, and high‑fatigue spring wire).
• Classification & ordering: Guidance on classification, ordering information purchasers must supply (grade, dimension, delivery condition).
• Production & delivery requirements: Requirements for production process control, delivery condition and method of delivery.
• Inspection & testing: Requirements and methods for sampling, test pieces and key tests including:
  • Chemical composition
  • Tensile strength
  • Decarburization
  • Surface discontinuities
  • Non‑metallic inclusions
  • Core segregation
  • Microstructure (including cementite network determination for high‑carbon wire rod)
• Quality system & documentation: Requirements for inspection documents, marking and dispute handling.
• Normative references: Incorporates general technical delivery requirements from ISO 404 and references specific test and sampling standards (e.g., ISO 377, ISO 6892‑1, ISO 10474).

Applications

EN ISO 16120-1:2017 is used by professionals involved in the steel and wire supply chain who require consistent, auditable specifications for wire-rod feedstock intended for wire production:

• Steel mills and rod producers - to define product characteristics and production controls.
• Wire-drawing and cold-rolling manufacturers - to ensure feedstock is suitable for downstream processing.
• Procurement and quality assurance teams - to write purchase orders and verify conformance.
• Testing laboratories and inspectors - to apply standardized sampling and test methods.
• Design and manufacturing engineers - to select appropriate wire-rod grades for components.
