Full title and description

Steel for the reinforcement of concrete — Headed bars — Part 1: Requirements. This International Standard specifies product requirements for steel headed bars used as reinforcement in concrete structures, covering headed bars with heads made of steel and providing classification, dimensional and material requirements, anchorage capacity criteria, tolerances and requirements for manufacture and qualification testing of continuously produced products.

Abstract

This part of ISO 15698 sets out the technical requirements for headed steel bars intended for use as reinforcement in concrete. It is a product standard (not an application standard) intended to cover a wide variety of products and to support development of new variants. The standard excludes headed bars with heads made from non‑steel materials, on‑site welded orthogonal end anchorages and tests for impact loading.

Scope

Specifies requirements for headed reinforcing bars with steel heads manufactured in continuous production and intended as reinforcement for concrete structures. The standard covers materials, head shape and dimensions, head bearing area, anchorage capacity, tolerances, classification of headed bars, qualification testing (including load transfer and head-to-bar robustness tests) and manufacturing-related requirements for welded, forged, threaded, swaged/extruded and other headed-bar types. It excludes heads or head‑bar connections using other materials, on‑site welded orthogonal end anchorages and tests for impact loading.

Key topics and requirements

• Material requirements for the bar and head (steel quality and compatibility).
• Head shape, dimensional limits and tolerances to ensure bearing area and fit.
• Specification of head bearing area and minimum anchorage capacity performance.
• Classification system and series of headed bars according to geometry and performance.
• Qualification testing: load transfer tests and robustness tests for the head‑to‑bar connection.
• Manufacturing requirements for different production methods (welded, forged, threaded, swaged, extruded, sleeve/bolted variants).
• Tolerances, marking and documentation required for product conformity and traceability.

Typical use and users

Used by manufacturers of headed reinforcing bars to define product design and quality, by structural and civil engineers specifying reinforcement for concrete elements requiring headed anchorage, by testing and certification laboratories performing qualification and batch testing, and by standards bodies and regulators adopting or referencing product requirements. Common applications include precast and cast‑in‑place concrete where mechanical headed anchorage is preferred or required.

Related standards

ISO 15698 is a multi‑part family; Part 2 covers test methods (ISO 15698-2:2012). ISO 15698 relates to the broader ISO series for steel reinforcement (for example the ISO 6935 series for plain, ribbed bars and welded fabric). National adoptions and related national standards (for example GB/T adaptations in China) exist that modify or adopt ISO 15698 content for local use. Users typically consult Part 2 (test methods) in conjunction with Part 1 (requirements) when specifying or verifying product performance.

FAQ

Q: What is this standard?

A: ISO 15698-1:2012 is an International Standard that specifies product requirements for steel headed bars used as reinforcement in concrete structures (headed bars with steel heads).

Q: What does it cover?

A: It covers material, dimensional and manufacturing requirements, classification, anchorage capacity, tolerances and qualification testing (load transfer and head‑to‑bar robustness tests) for continuously produced steel headed bars. It excludes non‑steel head materials, on‑site welded orthogonal end anchorages and impact‑loading tests.

Q: Who typically uses it?

A: Manufacturers of headed bars, structural/civil engineers specifying reinforcement, testing laboratories and certification bodies, product purchasers in precast and cast‑in‑place concrete markets, and standards/regulatory organizations.

Q: Is it current or superseded?

A: ISO 15698-1 was published in 2012 (Edition 1). According to ISO lifecycle information the publication is the 2012 edition and has been subject to ISO periodic review; users should check with ISO or their national standards body for any later confirmation, revisions or withdrawals before relying on it for new procurements.

Q: Is it part of a series?

A: Yes — ISO 15698 is a multi‑part product standard. Part 1 covers requirements (this document) and Part 2 covers test methods (ISO 15698-2:2012); other national or regional documents may implement or adapt the parts.

Q: What are the key keywords?

A: Headed bars, anchor plates, reinforcement steel, anchorage, load transfer test, head-to-bar connection, product requirements, ISO 15698-1:2012.
