B) NABL calibration.

Tile Abrasion Testing Machine as per IS:1237, 1706 The tile sample is pressed under a specified load against a grinding path, strewen evenly with an abrasive powder, revolving at the rate of 30 ± 1 rpm. At the end of 100 revolutions of the disc, the second parallel side of the tile is subjected to wear an equal number of revolutions of the disc. The wear of the tile is measured using AIM48101 thickness measuring device (which is supplied at extra cost). The Abrasion Testing Machine consists of a replaceable grinding path, fitted on to a disc rotating about its vertical axis. The rotating disc and the grinding path are enclosed by a circular tray. A bracket holds the specimen. The loading is by a counterbalanced lever. A funnel is provided to facilitate charging the grinding path with abrasive powder. Supplied complete with automatic pre-set revolution counter and one 7.5 kg weight, but without abrasive powder and thickness measuring device. Suitable for operation on 415 V. 50 Hz, 3 Phase AC supply
