ASTM D1044 (Haze), ASTM D4060 (Weight Loss) Taber Abrasion

Evaluation of a plastic material’s resistance to abrasion is done by Taber Abrasion ASTM D1044 (Haze) and ASTM D4060 (Weight Loss) methods. The actual abrasion occurred is easily assessed in terms of haze and weight loss.

Overview

The Taber abrasion test provides data on the surface abrasion resistance of plastic materials, organic coatings, and surface treatments under controlled exposure to an abrasion wheel. ASTM D 1044 provides data on the abrasion resistance of transparent plastic materials, expressed as the percentage increase in haze, while ASTM D 4060 provides data on the abrasion resistance of coatings and surface materials, expressed as the percentage weight loss.

Scope, Applications, and Benefits

Scope

ASTM D 1044 tests transparent plastic materials for percentage increase in haze after specified taber abrasion wheel cycles using a calibrated hazemeter, while ASTM D 4060 tests coated materials for weight loss after specified abrasion cycles using a precision analytical balance.

Taber abrasion testing evaluates:

Percentage haze increase in transparent plastic materials following defined abrasion wheel cycles
Weight loss and abrasion resistance index of organic coatings and surface treatment systems
Comparative abrasion resistance of plastic materials, coatings, and surface treatment systems
Effect of coating thickness, surface hardness, and material formulation on abrasion performance
Compliance against the defined haze increase and weight loss abrasion resistance requirements

Applications

Optical lenses, transparent covers, and glazing materials requiring haze abrasion data
Automotive headlamp lenses, instrument panel covers, and transparent plastic components
Organic coatings, paints, varnishes, and industrial surface treatments requiring weight loss data
Floor coatings, deck treatments, and protective coating systems requiring abrasion assessment
Material suppliers and coating formulators requiring ASTM D 1044 and ASTM D 4060 test data

Benefits

Provides reliable optical and gravimetric abrasion resistance data for material and coating selection
Supports material specification compliance and supplier verification programs
Identifies abrasion resistance deficiencies in plastic surfaces and coating systems before production
Delivers traceable abrasion test records for engineering and research submissions
Reduces design risk by verifying abrasion performance early in the material approval cycle

Frequently Asked Questions

ASTM D1044 and ASTM D4060 test procedures use a rotating platform with wheels to test abrasion resistance by measuring haze or weight loss, assessing the durability of materials such as coatings, plastics, and surfaces.

ASTM D1044 measures abrasion resistance by checking the increase in haze on transparent materials after abrasion. ASTM D4060 measures abrasion resistance by looking at the weight loss of coated or solid materials.

Taber abrasion tests are used on plastics, coatings, laminates, painted surfaces, flooring materials, and clear panels. These materials are found in automotive, electronics, architectural glazing, and industrial applications.

In Taber abrasion testing, samples rotate on a platform. Abrasive wheels apply controlled pressure, gradually wearing down the surface. This method assesses resistance to abrasion.

These tests measure abrasion resistance in a controlled lab setting. They might not fully reflect real-world wear, where various abrasives, contact pressures, environmental factors, and multi-directional stresses affect surface durability.
