Full title and description

STB BS EN 15167-2-2024 — Ground granulated blast furnace slag for use in concrete, mortar and grout — Part 2: Assessment and verification of constancy of performance. This document defines the scheme for assessment and verification of constancy of performance (AVCP) and the certification procedure applicable to ground granulated blast-furnace slag (GGBFS) used as a cementitious addition or constituent in concrete, mortar and grout.

Abstract

EN 15167-2:2024 specifies technical rules for factory production control, autocontrol testing of samples taken at the manufacturing plant, initial inspection and ongoing surveillance of production, audit testing, reporting and actions in case of non-conformity. It provides the AVCP scheme (including certification of constancy of performance) for GGBFS and is intended to be used together with the product standard EN 15167-1 (definitions, specifications and conformity criteria).

Scope

This part of EN 15167 specifies the scheme for assessment and verification of constancy of performance (AVCP) of ground granulated blast furnace slag for use in concrete, mortar and grout. It covers the tasks and procedures for certification bodies and manufacturers required to demonstrate and maintain constancy of performance, including factory production control, autocontrol testing, initial inspection, continuing surveillance, audit testing of samples, reporting and actions to be taken in case of non‑conformity; requirements for depots are also included. The document is to be applied in conjunction with EN 15167-1 (product definitions, specifications and conformity criteria).

Key topics and requirements

• Assessment and verification of constancy of performance (AVCP) scheme for GGBFS (including certification of constancy of performance).
• Factory production control (FPC) requirements and manufacturer responsibilities for internal quality control and documentation.
• Autocontrol testing procedures for samples taken at the manufacturing plant and required testing frequency.
• Initial inspection of the manufacturing plant and FPC, and continuing surveillance procedures for certification bodies.
• Audit testing of factory/depot samples and evaluation of representativeness and accuracy of key test results (e.g., 28‑day activity index — evaluation procedure in annex).
• Rules for reporting, handling non‑conformities and corrective actions.
• Requirements for depots/dispatching centres and their roles in conformity assessment.
• Alignment with AVCP tasks defined in the CPR Delegated Regulation and numbering/terminology updates vs. previous edition.

Typical use and users

Primary users are manufacturers of ground granulated blast‑furnace slag, quality/production managers at slag processing works, concrete and mortar producers, third‑party certification bodies, testing laboratories, and regulatory authorities responsible for construction product conformity under the Construction Products Regulation (CPR). The standard is used to demonstrate and certify the constancy of performance (durability, reactivity/activity index, chemical limits and other declared properties) of GGBFS when it is placed on the market.

Related standards

Commonly referenced and related documents include EN 15167-1 (Ground granulated blast furnace slag — Part 1: definitions, specifications and conformity criteria), EN 196‑7 (Methods of testing cement — sampling and preparation of samples), and other cementitious/additive product standards and CPR (Regulation (EU) No 305/2011) requirements for AVCP and CE marking. National implementations (BS EN, DIN EN, UNE‑EN, SFS‑EN, etc.) provide local forewords and adoption details.

FAQ

Q: What is this standard?

A: EN 15167-2:2024 is the European standard that defines the assessment and verification of constancy of performance (AVCP) and certification procedures for ground granulated blast‑furnace slag used in concrete, mortar and grout. It sets out how manufacturers and certification bodies demonstrate ongoing conformity of declared performance.

Q: What does it cover?

A: It covers factory production control, autocontrol testing, sampling and testing regimes, initial inspection and ongoing surveillance by certification bodies, audit testing, reporting, actions for non‑conformity and depot requirements. The document is intended to be applied together with EN 15167‑1 (product definitions and criteria).

Q: Who typically uses it?

A: Manufacturers of GGBFS and their quality managers, concrete and mortar producers who use slag as a constituent, testing laboratories, notified/certification bodies performing AVCP, and regulators administering construction product conformity under the CPR.

Q: Is it current or superseded?

A: EN 15167-2:2024 is the current edition published in 2024 and supersedes EN 15167-2:2006. National bodies implemented the 2024 text during 2024; users should refer to their national adoption (BS EN, DIN EN, UNE‑EN, etc.) for the officially published national text and any national foreword.

Q: Is it part of a series?

A: Yes — it is Part 2 of EN 15167. Part 1 (EN 15167‑1) covers definitions, specifications and conformity criteria for GGBFS. Part 2 defines the AVCP and certification scheme to be used together with Part 1.

Q: What are the key keywords?

A: Ground granulated blast‑furnace slag (GGBFS), AVCP, factory production control, certification, activity index, conformity assessment, concrete additives, CE marking, construction products.
