EN 16094 Martindale Micro-Scratch Testing
Martindale Micro-Scratch Testing is a method for evaluating the durability and scratch resistance of various products, including coatings, films, paints, and surfaces. Using a specialized tool called a Martindale Abrasion Tester, it entails repeatedly subjecting a sample to mechanical abrasion. This device simulates real-world wear and tear by applying controlled pressure and abrasive action to the sample.

Overview
EN 16094 Martindale Micro Scratch Testing evaluates the scratch resistance and surface durability of coatings, laminates, and treated surfaces using a standardized reciprocating scratch methodology. The test quantifies the resistance of a surface to micro-scratching under defined loads, providing measurable data on coating quality and wear resistance.
This method is widely adopted in the flooring, furniture, and automotive surface coatings industries to differentiate product performance, guide formulation development, and support material quality assessment under real-world surface contact conditions.
Scope, Applications, and Benefits
Scope
EN 16094 scratch testing is used to assess the scratch resistance and durability of coated surfaces under controlled loading conditions. It helps determine how well a coating withstands mechanical abrasion, maintains its appearance, and adheres to the substrate when subjected to repeated scratch cycles.
The test typically evaluates:
- Micro-scratch resistance under defined normal loads to measure the coating’s ability to resist surface damage
- Surface gloss retention after scratch cycles to assess any loss in visual finish or aesthetic quality
- Coating integrity and delamination behaviour, identifying cracks, peeling, or separation from the substrate
- Comparative performance between coating systems, enabling benchmark analysis of different formulations or protective layers
Applications
- Hard floor coverings and laminate flooring
- Furniture and decorative panel surface coatings
- Automotive interior and exterior trim coatings
- Consumer electronics enclosure finishes
- Architectural glass and protective coatings
Benefits
- Standardised, reproducible scratch assessment
- Quantifies surface quality differences between coating formulations
- Identifies coating failure modes (gloss loss, delamination, cracking)
- Supports product development and quality control
- Applicable to flat, rigid, and semi-flexible substrates
Test Process
Specimen Preparation
Test specimens are conditioned at 23 °C and 50% RH for 24 hours; surface gloss is measured before testing using a glossmeter.
1Scratch Application
A defined stylus or abrasive pad reciprocates over the surface under controlled load per EN 16094 parameters for a set number of cycles.
2Post-Test Assessment
The surface is re-examined under standard lighting, with gloss measured and scratches documented.
3Classification & Reporting
Scratch resistance is rated (MS0–MS2) based on gloss retention and visual changes per EN 16094.

Frequently Asked Questions
EN 16094 uses a reciprocating Martindale motion to simulate real-use micro-scratching under low loads, while conventional scratch tests (e.g., pencil hardness) apply a single directional stroke under higher loads. EN 16094 is better suited for fine surface durability differentiation.
The standard is primarily designed for hard floor coverings and their surface treatments but is also widely applied to furniture coatings, laminates, and any flat coating system requiring scratch resistance classification.
Scratch class is assigned by comparing pre- and post-test gloss values and visually assessing scratch visibility under defined illumination. MS0 indicates no visible change; MS2 indicates clearly visible scratches under normal lighting conditions.
Yes. It is highly effective for comparative studies, allowing formulators to rank coatings by scratch resistance and optimize coating chemistry, film thickness, and surface treatment.
Specimens should be clean, free of surface contamination, and conditioned at standard atmospheric conditions (23 °C/50% RH) for a minimum of 24 hours prior to testing.
