SIST EN 1128:1996

Overview

EN 1128:1995 is a CEN (European) standard that specifies a test method for determining the hard body impact resistance of cement-bonded particleboards. The standard applies to boards with a nominal thickness of 9 mm or greater and defines how to assess resistance to localised impacts from a hard striker. EN 1128:1995 is used to characterise mechanical durability and to provide comparable data for quality control and product specification.

Key topics and technical requirements

• Scope and applicability: Applies specifically to cement-bonded particleboards (nominal thickness ≥ 9 mm).
• Specimen preparation and conditioning: The standard requires defined specimen preparation and environmental conditioning so results are repeatable and comparable.
• Test apparatus and striker: A hard-body striker and a defined support/fixture arrangement are required to deliver controlled impacts. The standard specifies the type of impact action and how the test is performed.
• Damage assessment and measurement: Test results are based on evaluation of impact damage (visual assessment and measured damage parameters). The standard sets out how to record and report damage.
• Reporting requirements: Test conditions, specimen details, test environment, observed damage and numerical results must be reported to allow comparison between products and laboratories.
• Repeatability and reproducibility considerations: Procedures for multiple specimens and reporting of statistical values are included so laboratories can assess consistency.

(Note: EN 1128:1995 defines the method and reporting; specific acceptance criteria for product performance are normally set by manufacturers, regulators or project specifications.)

Applications

• Manufacturer quality control: Routine production testing to monitor impact resistance during manufacturing of cement-bonded particleboards.
• Product development and R&D: Comparing formulations, densities or surface treatments to improve impact durability.
• Third‑party testing and certification: Independent laboratories use the standard for conformity assessment and material data sheets.
• Specification and procurement: Architects, engineers and buyers reference test data based on EN 1128 when specifying boards for floors, cladding, ceilings or other building elements where impact resistance is required.
• Regulatory compliance and building code support: Provides objective mechanical property data useful for compliance demonstrations.

Who uses this standard

• Board manufacturers and plant quality departments
• Independent testing laboratories and conformity assessment bodies
• Product certifiers and notified bodies
• Architects, structural engineers and specifiers evaluating material suitability
• Procurement specialists writing technical specifications
