TEST:TPA
TRIGGER: XXX.X g
DEFORMATION: XXX.X mm
SPEED: XX.X mm/s
Figure III.19
The operator depresses the start button to begin the test. In a TPA test the compression and return
strokes of both cycles occur at the programmed test speed. Target deformation for both cycles begins
atthetriggerpositionoftherstcycle.
Duringthetesttherunningscreenisseenasshownbelow:
TEST: TPA CYCLES: 02
DEFORMATION: XXX.X mm
LOAD: XXXX.X g
Figure III.20
TPA cycles will count down to show the number of cycles remaining. Deformation and Load will
remain live displays during the test.
Testresultsareshownonthereportingscreen:
HARDNESS1: XXXX.X g
HARDNESS2: XXXX.X g
COHESIVENESS: XXX.XX
SPRINGINESS: XX.X mm
ADHESION: XXXX.X mJ
TEMP: XXX.X F
Figure III.21
Hardness1isthepeakloadoftherstcompressioncycle.
Hardness2 is the peak load of the second compression cycle.
Cohesiveness is the ratio of A2/A1. A2 is the area under the compression stoke of the second cycle
andA1istheareaunderthecompressionstokeoftherstcycle.Ifthestructureofthesampleis
completelydestroyedontherstcompression,thisratioiszero.Ifthesampleisperfectlyelasticand
notdamagedatallbytherstcompressionthisratiois1.0Mostfoodproductswillfallsomewhere
in between 0 and 1.
Springiness is a measure of how far the sample returns after being compressed to the target deformation.
Adhesiveness is a measure of stickiness and is calculated as the area under the negative peak as
probewithdrawsaftertherstcompression.
TENSION TEST – this test can be used to pull apart a sample, usually using grip xtures to
apply tension load on the sample.
