Description

Reference and test blocks are used for the quality analysis of the magnetic particle suspensions as well as for the estimation of MT overall performance. 

The reference block No.1 is a disc with 2 types of natural cracks on the surface. Coarse cracks are the result of the polishing, fine cracks are the result of stress corrosion. The block is permanently magnetized by central conductor through the hole. Estimation of magnetic particle suspensions is made by visual or other appropriated method of comparison of the indications.
