Overview
EN 14158:2004 - published by CEN - specifies a standardized method for the determination of rupture energy by impact of natural stone. The standard covers procedures to assess how much energy a stone specimen absorbs before fracture when subjected to an impact load. EN 14158:2004 includes provisions for both an identification test and a technological test used in Factory Production Control (FPC) of finished products.
Key topics and requirements
The standard focuses on the following technical topics and requirements:
- Scope and purpose: Defines the objective of measuring rupture energy to characterize impact resistance of natural stone.
- Test types: Distinguishes between an identification test (for material characterization) and a technological test (for ongoing FPC of finished products).
- Specimen handling: Requirements for sampling, specimen preparation and conditioning prior to testing to ensure reproducibility.
- Test apparatus and instrumentation: General requirements for impact devices, measurement systems and calibration to obtain reliable energy readings.
- Test procedure and measurement: Method for applying an impact load, measuring the absorbed energy up to rupture, and calculating rupture energy values.
- Reporting and documentation: Minimum information to be recorded and reported, enabling consistent interpretation and traceability for quality control.
- Use in FPC: Guidance on how the technological test can be integrated into factory production control protocols for finished stone products.
Note: EN 14158:2004 sets procedural and reporting requirements but does not prescribe performance pass/fail criteria - these are typically determined by project specifications, product standards, or contractual rules.
Applications
EN 14158:2004 is practical and relevant for:
- Stone manufacturers and fabricators carrying out FPC for cladding, paving, countertops and other finished products.
- Materials testing laboratories performing impact resistance characterization and product certification.
- Quarry operators and product developers evaluating raw blocks and slabs for suitability in engineered applications.
- Architects, façade engineers and specifiers who need reliable data on impact behavior for design and safety assessments.
- Regulatory and conformity bodies that require standardized test evidence for acceptance, compliance or performance declarations.
Related standards
Complementary natural stone test methods typically used alongside EN 14158 include standards for:
- Flexural and compressive strength testing
- Water absorption and porosity assessment
- Freeze-thaw and frost resistance testing
- Abrasion and wear resistance methods
Using EN 14158:2004 together with these tests provides a comprehensive profile of natural stone performance for both design and quality control.
