Testing Equipment Required for ASTM D3574 Urethane Foam

ASTM D3574 (D 3574) applies to slab, bonded, and molded flexible cellular urethane foams.  There are many tests in this specification including tests for density, ball rebound, airflow, etc.  However, the most common tests in the specification are these mechanical tests:

1. Test B1 - Indentation Force Deflection Test (IFD) - Specified Deflection

2. Test B2 - Indentation Force Deflection Test (IFD) - Specified Force

3. Test C - Compression Force Deflection (CFD)

4. Test E - Tension Test

5. Test F - Tear Resistance Test

All of these tests are performed on a universal testing machine, often times referred to as a tensile testing machine.  The machine control software must be capable of segmented machine control testing profiles.  Not all testing machines will perform these tests correctly; All ADMET testing machines equipped with MTESTQuattro software are capable of these tests.

Other equipment needed to perform the tests described above are:

Tests B1, B2, C 

1. Circular 8" compression platen with a swivel joint

2. Square 16" x 16" (min.) compression platen with 6.5mm holes on 20mm centers

Tests E, F 

 1. Manual or pneumatic vise grips with serrated inserts

That is the end of the equipment requirements.
