Main features:
When a laboratory has to prove that every cube, cylinder and brick meets specification, the accuracy of the compression frame decides whether the results are trusted. The KASON CTM206F answers that requirement with a 2000 kN capacity, Class 1 accuracy and fully closed-loop force control.
The machine is built to EN 12390-3 and EN 12390-4, and its measurement chain is verified against ISO 7500-1, ASTM E4, EN 10002-2, BS 1610 and DIN 51220; Test procedures follow BS 1881, ASTM C39, AASHTO T22, NF P18-411 and UNE 83304. It therefore covers compressive and flexural strength Testing of cement, concrete and bricks at a constant load rate or constant stress rate.
A high-precision digital servo valve and PID closed-loop control hold the selected rate within ±1% of the indicated value over the 2%–100% measuring range. The motorised leadscrew adjusts the test space electrically to 320 mm, so 100 mm, 150 mm and 200 mm cubes, 400×200×400 mm blocks and Ø150×300 mm cylinders can all be tested on one frame. Column clearance is 280 mm, the platens are 320 mm and piston stroke is 30 mm.
Operation is automatic: the microcomputer measures the load, detects fracture, calculates strength and prints the report, while overload protection stops the pump motor once force exceeds 3% above maximum. The set is supplied complete with oil console, industrial computer, A4 printer, hydraulic force sensor, compression shield, manual and certificate of conformity. The mainframe measures 550×550×1200 mm, the cabinet 1100×750×900 mm, total weight is about 1100 kg and power demand is only 1.1 kW at AC 380 V.
