Overview

EN 14617-9:2005 - Agglomerated stone: Test methods - Part 9: Determination of impact resistance is a CEN standard that specifies a controlled drop‑weight test to determine the impact resistance of agglomerated flat stone products. The method uses a steel sphere dropped from increasing heights onto specimens buried on a sand bed, with results expressed as fracture work (joules). This test is intended for quality control, product development and comparative assessment of agglomerated stone panels and tiles.

Key topics and technical requirements

• Test principle: Impact resistance is measured by dropping a spherical steel ball onto specimens until breakage, then calculating fracture work.
• Apparatus:
  • Steel sphere: mass 1.0 kg ± 0.1 kg, diameter ≈ 6.3 cm.
  • Electromagnet and release switch mounted on a vertical graduated stick (0–120 cm, 5 cm divisions).
  • Sand‑filled box (min. 40 × 40 cm section, ≥30 cm high) with dry sand bed ≥20 cm deep; sand grain size 1.0–1.5 mm.
• Specimen preparation:
  • Minimum of four specimens, nominal size 20 × 20 cm.
  • Thickness between 0.5 cm and 3 cm, equal to final product thickness.
  • Main faces parallel; tested face finished as in final product (sand‑blasted, gauged or polished) - no chemical surface treatment.
• Test procedure:
  • Specimen centred and fully buried in sand with top face horizontal.
  • Sphere released (initially at 6 cm reference) and drop height increased in 5 cm increments until breakage.
  • Record any visible surface damage and the drop height that causes fracture.
• Result expression:
  • Fracture work L = M × h × g (M in kg, h in m, g = 9.806 m/s²).
  • Report the value for each specimen and the average across at least four specimens.
• Test report content: Unique report ID, standard reference, laboratory and client details, specimen description (size, surface finish, binders), dates, observed damage, individual and average fracture work, deviations, and signatures.

Applications and users

• Manufacturers of agglomerated stone for product development, performance verification and production quality control.
• Testing laboratories performing standardized mechanical tests and issuing conformity reports.
• Specifiers, architects and engineers assessing suitability of agglomerated stone for floors, claddings and worktops where impact resistance matters.
• Purchasing and compliance teams verifying supplier claims and ensuring products meet procurement or regulatory requirements.

Related standards

• Other parts of EN 14617 (e.g., Part 1 density/water absorption, Part 2 flexural strength, Part 4 abrasion resistance, Part 10 chemical resistance, etc.).
• EN 14618 (Agglomerated stone - Terminology and classification) and EN 12440 (Natural stone - Denomination criteria) are relevant references for classification and material identification.
