STANDARDIZED TESTS FOR CERAMIC TILES AND BRICKS
''VR'' COOLING TANKS
Suitable for determining the resistance to thermal shock.
UNI EN ISO 10545-9 European norm.
According to the norm, each sample must undergo 10 heating and cooling cycles. The sample must be heated in a thermostatic stove and cooled in accordance to 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 a water absorption of over 10% are indirectly cooled without immersion (VR/60/B tank).
