DIN 52347 - Testing of Glass and Plastics — Determination of Abrasion Resistance Using Abrasive Wheels and Measurement of Scattered Light

DIN 52347 defines a test method for assessing the abrasion resistance of glass and transparent plastics, particularly materials such as safety glass for motor vehicles. The standard evaluates surface durability by measuring the increase in scattered light caused by abrasion.

Scope:

Applicable Materials:

• Glass and transparent plastics, especially safety glass used in motor vehicles.

Testing Methodology:

• The test specimen is subjected to sliding abrasion using two rotating abrasive wheels on a rotary platform.

• The increase in scattered light due to surface damage is measured as an indicator of abrasion resistance.

Specimen Preparation:

• Samples are prepared to specified dimensions and conditions as outlined in the standard.

Assessment Parameters:

• Abrasion resistance is evaluated based on the amount of scattered light caused by surface changes.

Applications:

Automotive Industry:

• Used to assess the abrasion resistance of safety glass in vehicles.

Material Development:

• Helps manufacturers test the durability of new glass and plastic materials.

Quality Control:

• Ensures compliance with durability standards during production.

Standardization:

• Provides a consistent method for evaluating abrasion resistance of glass and plastic materials.
