THERMAL SHOCK TESTING

Standardised Cooling Tanks, suitable for determining the resistance to thermal shock in accordance to the UNI EN ISO 10545-9. According to the standard, each sample must undergo 10 heating and cooling cycles.

The sample must be heated in a thermostatically controlled drying oven and cooled in accordance with one of two methods, depending on the water absorption of the samples examined.

Tiles with a low porosity (water absorption of less than 10%) are immersed in water (VR/60/A tank).

Glazed tiles with water absorption of over 10% are indirectly cooled without immersion (VR/60/B tank).

Standardized tank, model VR/60/A.
  • Designed for cooling ceramic tiles by immersing them in water;suitable for sizes of up to 60x60 cm.
  • Entirely made of stainless steel. The water supply is adjustable thanks to the provision of a flowmeter with a scale of 0 to 5 litres/min, (the standard mentions a flow rate of 4 litres/minute).
  • Water drainage outlet with pipe fitting.
  • Stainless steel bucket for samples, featuring 4 vibrationdamping feet, adjustable height.
  • Overall dimensions: 85x38x93 cm.Gross weight: 38 kg.

Standardized tank, model VR/60/B

  • Designed for the indirect cooling of ceramic tiles, without immersion; suitable for sizes of up to 50x50 cm.
  • Tank structure made of stainless steel.
  • Top aluminium plate with adjustable feet made of stain-less steel, handles and raised edge for retaining the aluminium granules. The water supply is adjustable thanks to the provision of a flowmeter with a scale of 0+5litres/min. (the norm mentions a flow rate of 4 litres/minute).
  • Water drain-age outlet with pipe fitting. 4 vibration-damping feet, adjustable height.
  • Supplied complete with a 5 kg pack of aluminium granules of different diameters (from 0.3 to 0.6 mm).
  • Overall dimensions 74x57x26 cm. Gross weight 21 kg.
