Full title and description

STB BS EN 12620:2013 — Aggregates for concrete. European standard (adopted as a British/contracting technical publication) that specifies properties, testing and designation of natural, manufactured and recycled aggregates and filler aggregates intended for use in concrete, including concrete for roads, pavements and precast products.

Abstract

This standard sets requirements and assessment procedures for aggregates used in concrete production. It covers geometrical, physical and chemical properties, rules for grading and density, limits for harmful substances, conformity assessment provisions and requirements for marking and designation. It also includes informative and normative annexes giving guidance on grading illustrations, description of coarseness/fineness, reduced grading tolerances and assessment of fines.

General information

• Status: Published (national adoption of EN 12620:2013). Note: some national bodies list the 2013 adoption as withdrawn or replaced by other national editions; national status may vary.
• Publication date: 31 May 2013
• Publisher: British Standards Institution (BSI) / European Committee for Standardization (CEN) (national adoption as BS EN)
• ICS / categories: 91.100.15 (Mineral materials and products); 91.100.30 (Concrete and concrete products)
• Edition / version: 2013 edition (BS EN 12620:2013)
• Number of pages: Approximately 60 pages

Scope

The standard specifies properties and requirements for aggregates and filler aggregates obtained from natural, manufactured or recycled materials and mixtures intended for use in concrete (including concrete conforming to EN 206). It covers aggregates having an oven-dried particle density greater than 2,00 Mg/m³ (2 000 kg/m³) and gives provisions for recycled aggregates with particle densities down to about 1,50 Mg/m³ (1 500 kg/m³) with appropriate caveats. The scope includes requirements on geometry, physical and chemical characteristics, and conformity assessment; it also addresses marking, designation and restrictions on dangerous substances.

Key topics and requirements

• Definitions and terms relevant to aggregates for concrete.
• Geometrical requirements: grading, particle size distributions and tolerances (including illustrative annexes).
• Physical requirements: particle density, water absorption, shape, resistance to fragmentation and wear, frost resistance and durability-related tests.
• Chemical requirements: limits on deleterious substances and guidance on assessment of potentially hazardous constituents.
• Requirements and procedures for evaluation of conformity of aggregates (links with EN 16236 for conformity assessment).
• Designation, marking and labelling rules to describe aggregate properties for specification and delivery.
• Annexes providing guidance on grading illustrations, coarseness/fineness description, reduced grading tolerances and assessment of fines.

Typical use and users

Used by aggregate producers and processors, concrete producers (ready-mix and precast), construction specifiers and engineers, testing laboratories, certification bodies and contractors. The standard is applied when specifying, producing, testing and accepting aggregates for structural and non-structural concrete, road pavements and precast concrete products.

FAQ

Q: What is this standard?

A: BS EN 12620:2013 (adopted nationally as indicated by the STB/BS prefix in the title) is the European technical standard that defines requirements and test criteria for aggregates and filler aggregates intended for use in concrete.

Q: What does it cover?

A: It covers geometrical, physical and chemical properties of natural, manufactured and recycled aggregates for concrete, grading and tolerances, limits on harmful substances, conformity assessment rules and marking/description conventions, plus annexes with guidance on common sizing and grading issues.

Q: Who typically uses it?

A: Aggregate producers, concrete manufacturers (ready-mix and precast), design engineers, specifiers, testing laboratories, certification bodies and contractors involved in concrete production and acceptance.

Q: Is it current or superseded?

A: The standard was published as the 2013 edition (31 May 2013). National adoption and status can vary: some national catalogues show the 2013 adoption as published, others list it as withdrawn or replaced by alternate national arrangements referencing EN 12620:2002+A1:2008. Always check the current status with your national standards body before relying on it for regulatory or contractual work.

Q: Is it part of a series?

A: It is part of the family of European standards covering aggregates and concrete testing and specification (e.g., EN 206 for concrete, EN 13055 for lightweight aggregates, EN 932/933/1097/1367/1744 test-series). National guidance documents (for example PD 6682‑1 in the UK) provide application guidance for BS EN 12620 in local practice.

Q: What are the key keywords?

A: Aggregates, concrete, grading, density, water absorption, recycled aggregate, conformity, marking, EN 12620.
