Overview

CR 12793:1997 (adopted as SIST CR 12793:2001) is a CEN-related standard for the measurement of the carbonation depth of hardened concrete. The published national version (Slovenian: Merjenje globine karbonatizacije strjenega betona) aligns with the original reference and targets assessment of concrete carbonation as part of durability evaluation. The formal scope text is not available in the extract, but the document title and indexing (ICS 91.100.30) indicate it defines procedures and requirements for determining carbonation depth in hardened concrete.

Key topics

Although the full text is not provided here, standards of this type typically address the following technical topics and requirements:

• Definitions and terminology related to carbonation and hardened concrete.
• Sampling and specimen preparation to ensure representative and reproducible results.
• Measurement procedures for determining carbonation depth on exposed concrete surfaces.
• Environmental and conditioning requirements before and during testing to avoid biased results.
• Accuracy, repeatability and reporting requirements including how to record results and relevant metadata (location, concrete cover, exposure conditions).
• Health and safety considerations for laboratory and field testing.
• Quality control and traceability for test equipment and personnel competence.

Note: The above topics reflect common content in standards on carbonation measurement; users should consult the official CR 12793:1997 / SIST CR 12793:2001 document for exact procedural details and mandatory requirements.

Applications

This standard is valuable for practical tasks including:

• Durability assessment and service-life estimation of reinforced concrete structures.
• Condition surveys to identify carbonation penetration and risk of reinforcement corrosion.
• Quality control on new concrete works to verify cover and resistance to carbonation.
• Maintenance planning and repair specification where measured carbonation depth informs intervention timing.
• Research and comparative testing where standardized measurement enables consistent datasets.

Who should use it

• Materials and concrete testing laboratories
• Structural and civil engineers focused on durability and asset management
• Construction quality managers and contractors
• Infrastructure owners and facility managers
• Academics and researchers studying concrete carbonation and long-term performance

Related standards

CR 12793:1997 sits within the body of European and national standards on concrete durability and testing methods. Users often apply it alongside other CEN/EN and national standards covering concrete sampling, cover measurement, and corrosion assessment. For definitive procedures and cross-references, obtain the full official standard from the national standards body (SIST) or CEN.
