INITIAL SURFACE ABSORPTION TEST APPARATUS (ISAT)

Model Number : TM-252

The Initial Surface Absorption Test (ISAT) apparatus is used to measure the rate of water absorption on the surface of concrete. This test provides an indicator of the permeability of the concrete surface, which directly relates to its durability. High initial absorption can indicate low durability and higher susceptibility to freeze-thaw cycles, chloride ingress, or carbonation. As per BS 1881: Part 208:1996.

Techincal Specification

AS PER BS 1881 PART 208:

This apparatus is used to assess the surface absorption characteristics of concrete. The rate of flow of water per unit area into a concrete surface when subjected to a constant head of 200 mm is measured. The unit consists of a capillary tube mounted on a scale, a water reservoir & connecting tubes. Easy to use, mounted on a stand. As per BS 1881: Part 208:1996
