Automatic dual-head abrasion tester NIP-DH2800 - Application

The professional Automatic Dual‑Head Rotary Abrasion Tester NIP‑DH2800 is for the High-precision assessment of surface durability, abrasion resistance and coating integrity Developed according to standardized rotary abrasion processes. The device generates controlled abrasion via two independently driven abrasion heads, through which simultaneous examinations Identical or different samples can be tested under identical load and speed conditions. This dual-head configuration increases the Repeatability, reduces the Operator influence and supports advanced comparative tests.

ASTM Test Method Description (Taber Abrasion – ASTM D4060 / ASTM D1044 / ASTM D3884)

The ASTM rotational wear standards quantify the Abrasion resistance of coatings, plastics, laminates, floor coverings and industrial surfaces, by measuring the material loss after a defined number of abrasion cycles. The method simulates long-term mechanical stress through controlled rotational friction.

ASTM process using the NIP-DH2800

Sample preparation

• The test specimen is cut to the required ASTM dimensions.

• The surface is cleaned and conditioned to remove dust, oils, or contaminants.

• The sample is securely fixed to the abrasion platform using the precise clamping system.

Selection of abrasion wheels

• Abrasion wheels are selected according to the ASTM material category (e.g. CS-10, CS-17, H-18, H-22).

• The NIP-DP2800 enables quick wheel changes and parallel dual-head testing.

Load configuration

• Standard ASTM loads (typically 250 g, 500 g or 1000 g per wheel) are applied using calibrated weights.

• The dual-head system ensures identical loading on both test stations.

Rotary wear cycle

• The test starts with the programmed number of cycles (e.g., 100, 500, 1000 cycles).

• The sample rotates under the abrasion wheels at the ASTM-defined speed.

• The wheels generate a through continuous contact uniform abrasion path.

Measurement of material loss

After completion of the cycles, the sample is taken and cleaned. The abrasion is determined by:

• Mass loss (mg)

• Wear Index

• Visual surface changes

The dual-head configuration of the NIP-DP2800 enables direct comparison tests between two materials or two coatings under identical conditions.

ASTM results

• Wear Index (WI)

• Mass loss per cycle

• Visual abrasion classification

• Comparative durability assessment

These results support Quality assurance, R&D and Material certification.

ISO test method description (ISO 5470-1 – Rotary abrasion)

ISO 5470-1 defines a standardized procedure for the evaluation of Abrasion resistance of flexible and rigid materials by rotary abrasion. The method ensures globally comparable abrasion performance data for coatings, polymers, textiles and industrial surfaces.

ISO workflow with the NIP-DH2800

Sample conditioning

• The sample is conditioned under ISO-specified temperature and humidity conditions.

• The stable platform of the NIP-DP2800 ensures precise sample positioning.

Selection of abrasion wheels

• ISO wheels (e.g. CS-10, CS-17, H-18) are installed according to the material type.

• Dual-head operation enables parallel ISO testing.

Applied load

• ISO loads are applied using calibrated weights.

• The device ensures precise vertical force distribution on both heads.

abrasion cycle

• The sample rotates under the wheels at the ISO-defined speed.

• The abrasion heads generate a through continuous friction standardized abrasion path.

• The automatic cycle control of the NIP-DP2800 ensures exact ISO compliance.

Abrasion rating

After the test, the sample is cleaned and evaluated. The ISO abrasion performance is determined by:

• Mass loss

• Thickness reduction

• Surface changes

• ISO Wear Index calculations

ISO results

• Mass loss (mg)

• Wear Index

• Surface classification

• Internationally comparable abrasion data
