Vicat Heat Deflection Tester
Confirm to ASTM D1525 ISO 306 GB T1633 Standard

QC-655 Vicat softening of temperature (VST) is the specimen was measured by the fixed load 1kg (or 5kg). When the cross-sectional 1mm² of standard needle punctures into surface 1mm deep of temperature, the testing specimen of ambient temperature should be 50 degrees per hour in rise speed steady. The specimen requires 3mm ~6.5mm (thickness) and size will be 10x10mm or dia. 10mm at least.
