Frequently Asked Questions
ASTM D785 uses a Rockwell hardness tester to measure the indentation hardness of plastics and electrical insulating materials. It helps evaluate the material's resistance to deformation.
The Rockwell hardness test describes how resistant the plastic material is to indentation. This data is helpful for quality control and performance evaluation when choosing a material for manufacturing processes.
Edge clearance is critical in avoiding damage to the specimen during testing and ensuring that results are not affected by inaccuracies in a test machine due to its proximity to the specimen's edge.
If it is too deep, the manufacturer should use a lower load scale to avoid damaging the specimen with more profound induction. It may also show that the material is softer than expected, which can influence the outcome.
ASTM D785 provides the hardness value and information related to the relative toughness, wear resistance, and elastic deformation of material regarding load, which are vital issues in selecting various materials.
