ASTM D3574 Step By Step
- Measure the specimen thickness.
- Place the specimen on the lower platen in the compression tester.
- Bring the upper compression platen down to touch the specimen 75-80% of the original thickness at a rate of 250 mm per minute.
- Allow the specimen to rest for 6 minutes with no contact from the platen to specimen.
- Bring the platen down into contact with the specimen at 50 mm per minute and determine the thickness at a force of 4.5 N.
- Indent the specimen at 50 mm per minute by 25% of thickness. Determine the force after 60 seconds.
- Increase the deflection to 65%. Determine the force after 60 seconds.
- Compress the specimen 25% of this thickness at 50 mm per minute.
- Analyze the results with MTGenius Test Software.
