ISO IEC 10025-1-1995 PDF

Full title and description

St ISO IEC 10025-1-1995 — (likely a mis‑designation). The correct, commonly referenced title for this subject is "Hot rolled products of structural steels — Part 1: General technical delivery conditions" (EN/ISO style designation EN 10025-1 / ISO 10025-1). This Part 1 sets out general delivery, inspection and testing requirements that apply across the EN 10025 series for hot‑rolled flat and long structural steel products (plates, sections, bars, strips), excluding structural hollow sections and coated products.

Abstract

This document summarizes the purpose and main content of Part 1 of the EN/ISO 10025 series: it defines purchaser information, product designation and marking, general technical delivery conditions, required properties (chemical and mechanical), sampling and testing rules, factory production control, evaluation of conformity and tolerances applicable to hot‑rolled structural steels. Part 1 provides the overarching rules that are then applied together with the specific technical requirements given in Parts 2–6 for particular steel groups and grades.

General information

• Status: In common practice the EN 10025-1 text is maintained as a European standard (harmonized in the EN system); earlier 1990s editions have been superseded by later revisions.
• Publication date: EN 10025-1:2004 (published November 2004) is the widely referenced edition of Part 1; the EN 10025 series was later consolidated/revised (reference edition EN 10025:2019 — users should check their national standards body for the formally current national implementation and any amendments).
• Publisher: European Committee for Standardization (CEN) for EN editions; national standards bodies publish national adoptions. (The ISO/IEC prefix in the user title appears to be a mis‑label — this steel standard is normally an EN/CEN product rather than ISO/IEC.)
• ICS / categories: 77.140.10 (Heat‑treatable steels); 77.140.50 (Flat steel products and semi‑products).
• Edition / version: Commonly cited edition: EN 10025-1:2004 (Part 1). The EN 10025 series has later consolidated editions — see EN 10025:2019 for series‑level revision. National adoptions (e.g., BS EN, DIN, SIST, etc.) may show their own edition references and amendment history.
• Number of pages: Typical published EN 10025-1:2004 documents are about 30–40 pages (the BS/EN published PDF version lists 36 pages for the 2004 edition).

Scope

Part 1 gives the general technical delivery conditions for hot‑rolled structural steels intended for welded, bolted and riveted structures. It applies to flat and long products (plates, sheets, strips, bars, sections, profiles) and covers: purchaser information and options, designation system, general manufacturing and delivery conditions, chemical and mechanical property verification, sampling and testing procedures, evaluation of conformity and marking. It excludes structural hollow sections and products covered by other specific standards or coating standards.

Key topics and requirements

• Information to be supplied by the purchaser (mandatory data and selectable options).
• Designation and classification of steel grades and qualities (links to EN 10027 and the grade system such as S235, S275, S355, etc.).
• General technical delivery conditions: supply conditions (+AR, +N, +M, +SR, etc.) and permitted manufacturing routes.
• Chemical composition requirements and product/ladle analysis rules.
• Mechanical property requirements (yield strength, tensile strength, elongation) and toughness/impact testing options and temperatures.
• Sampling, preparation of test pieces and testing methods; acceptance criteria for tests.
• Factory production control (FPC), initial type testing, supplementary testing and documentation.
• Evaluation of conformity, marking, shipment documentation and inspection certificates (requirements equivalent to EN 10204 inspection documents).
• Dimensional tolerances, mass tolerances and surface condition rules relevant to delivery.

Typical use and users

Used by steel producers (mills), steel stockholders, fabricators, structural engineers, procurement/specification teams, quality and inspection personnel, testing laboratories and regulators. Typical applications include building and bridge construction, offshore structures, heavy machinery, and any project where hot‑rolled structural steel supply and verification must be specified.

Related standards

Commonly referenced companion standards include EN 10025‑2 through EN 10025‑6 (the specific parts for non‑alloy, normalized, thermomechanically rolled, weathering and quenched & tempered steels), EN 10027 (designation), EN 10204 (inspection documents), EN ISO test method standards (impact, tensile, chemical analysis), and Eurocode EN 1993 (design of steel structures). National adoptions and equivalents (BS EN, DIN EN, SIST EN, etc.) are also closely related.

FAQ

Q: What is this standard?

A: It is Part 1 of the EN/10025 family covering general technical delivery conditions for hot‑rolled structural steels (general rules that apply across the series).

Q: What does it cover?

A: It covers purchaser information requirements, product designation, general delivery and manufacturing conditions, chemical and mechanical property verification, sampling and testing procedures, factory production control, conformity evaluation, marking and dimensional tolerances for hot‑rolled structural steel products.

Q: Who typically uses it?

A: Steel producers, stockholders and suppliers; structural designers and engineers; fabricators; quality/inspection teams and testing laboratories; procurement and standards compliance officers for construction and heavy engineering projects.

Q: Is it current or superseded?

A: The "1995" element in the user title appears to be a mis‑designation. The widely referenced Part 1 edition is EN 10025‑1:2004 (published November 2004). The EN 10025 series has been reviewed and consolidated in later revisions (series consolidated as EN 10025:2019 at series level). For purchase, application or legal/harmonization purposes, check with your national standards body for the officially current national adoption and any amendments as of the date you need to apply the standard.

Q: Is it part of a series?

A: Yes — it is Part 1 of the EN 10025 series (Parts 1–6). Part 1 provides general rules that must be used together with Parts 2–6, which contain the specific delivery conditions for particular groups of structural steels.

Q: What are the key keywords?

A: Hot rolled, structural steels, delivery conditions, EN 10025‑1, chemical composition, mechanical properties, sampling, testing, conformity, S235, S355.
