The SN EN 206+A2:2021 standard defines the specifications, performance, and conformity requirements for concrete materials used in construction. Published by the Société suisse des ingénieurs et des architectes (SIA), this standard applies to a wide range of construction activities, ensuring that concrete products meet rigorous quality and safety benchmarks.

Purpose and objectives

The primary objective of the SN EN 206+A2:2021 standard is to ensure that concrete used in construction meets specific durability and performance criteria. This standard aims to provide a clear framework for the production, testing, and conformity assessment of concrete, thereby facilitating consistency and reliability in construction practices. It supports the construction industry in achieving high-quality outcomes by outlining essential requirements that guide manufacturers and specifiers in their processes.

Scope: who must comply

The SN EN 206+A2:2021 standard applies to a diverse range of stakeholders in the construction industry, including:

• Concrete manufacturers producing ready-mixed and prefabricated concrete.
• Construction companies involved in building and civil engineering projects.
• Engineers and architects who specify concrete materials for their designs.
• Quality control and testing laboratories assessing concrete compliance.

This standard is crucial for ensuring that all concrete products used in construction meet the required durability and safety standards, promoting a safe built environment.

How SN EN 206+A2:2021 relates to other standards

The SN EN 206+A2:2021 standard is closely related to several other important standards in the construction industry:

• EN 206:2013+A2:2021: This is the European standard that SN EN 206+A2:2021 builds upon, providing foundational specifications for concrete.
• SIA 262.051+A2: This standard complements SN EN 206+A2:2021 by detailing additional Swiss regulations for concrete in construction.
• ISO 9001: This international standard for quality management systems is relevant for organizations seeking to ensure consistent quality in their concrete production processes.

Revision history and current status

The SN EN 206+A2:2021 standard is published by the Société suisse des ingénieurs et des architectes (SIA) and represents the latest revision of the standard, reflecting changes made in 2021. Key updates in this revision include improved guidelines on durability requirements and enhanced conformity assessment procedures, ensuring that the standard remains relevant and effective in today's construction landscape.
