3 HDT/VICAT TESTING Vicat standards HDT standards ISO 306, ASTM D 1525 and equivalent ISO 75, ASTM D 648, DIN and equivalent Vicat softening temperature (VST) The Vicat softening temperature is the temperature at which a standard indenter penetrates 1mm into the surface of a plastic test specimen, under a constant load, when the temperature is raised at a uniform rate. A distinction is drawn between: Method A = 10 N load, Method B = 50 N load, and rates of increase in temperature from 50 C/h or 120 C/h Heat deflection temperature (HDT) The temperature at which a sample subject to a three point bending under load occurs a specified deflection, while the temperature is raised at uniform rate (120 C/h) A distinction is drawn between three different methods: HDT Method A: Flexural stress s = 1.8 N/mm² = const., HDT Method B: Flexural stress s = 0.45 N/mm² = const., HDT Method C: Flexural stress s = 8.0 N/mm² = const., 3

4 WHAT IS HDT TEST? HDT = HEAT DEFLECTION TEMPERATURE TEMPERATURE OF DEFLECTION UNDER LOAD 4

5 WHAT ARE THE HDT TEST STANDARDS? ISO 75-1 (plus -2 and -3) ASTM D648 Geometry + span between support: 64mm-100/101,6 mm Stress (1,8 0,45 8 MPa) (1,82 0,455) Temperature ramp (120 C/h) (120 C/h) Deflection (function of thickness) (0,25 mm) Flatwise Position Edgewise Position 5

6 HDT TEST RESULTS Typical graph from a test: deformation vs temperature (or time). 6

7 WHAT IS THE VICAT TEST? VICAT = Temperature at which a thermoplastic starts to soften quickly A VICAT test station 7

8 WHAT ARE THE VICAT TEST STANDARDS? ISO 306 ASTM D1525 Geometry penetration of 1 mm Force (10N for method A or 50N for method B) Temperature rate (50 C/h or 120 C/h) Geometry of the indenter (1 mm 2 ) circular cross section Results always refer to A50 or B50 or A120 or B120 8

10 DIFFERENCE BETWEEN HDT AND VICAT HDT Station VICAT Station 10

11 HDT-3 & HDT-6 : test station One station for both HDT and Vicat : only the head is changed to switch from HDT to Vicat (pieces 12 & 13) the station is calibrated in house and thermal compensation due to station thermal expansion is already taken into account (all CEAST test stations are having thermal expansion correction) 11

12 HDT AND VICAT INSTRUMENTS Traditional oil systems HDT 3 Vicat HDT 6 Vicat HDT Vicat Auto and Autoplus 12

13 Why should we cool the unit? At the end of the test, we need to cool down the oil bath to be able to restart another test either we cool down using tap water circulation or we connect to a chiller (faster and saving water) 13

Limits of traditional systems Temperature limitations (< 300 C) Not safe at high temperature (fire hazard, pollution, ) Variation of homogeneity depending on grades Can not be used for testing the

14 Limits of traditional systems Temperature limitations (< 300 C) Not safe at high temperature (fire hazard, pollution, ) Variation of homogeneity depending on grades Can not be used for testing the new families of materials (PEEK, PEI, highly reinforced grades, tailored nanocomposites, ecc ) Oil needs to be handled and replaced Physical properties are different after a high number of cycles Environment-unfriendly (1 kg is able to cover a water surface of 1000 m 2 ) 14
