  2. Dimensions Tolerance Test on Bricks  

This test helps us to find the dimension of our bricks and also to check whether the brick we are using has a standard size or not.

 

  2.1. Required Material  

a. 20 Bricks

 

Dimensions Tolerence Test

 

  2.2. Procedure  

Dimensions Tolerance Test on Bricks are carried out in the following ways:

(a) Take twenty bricks at random.

(b) Separate any loose particles of clay and projecting blisters, if present in the bricks.

(c) Manage the bricks on a smooth level ground surface in a straight series in such a way that the adjoining surfaces are in touch with each other.

The arrangement will be performed in accordance with the dimension of the bricks that are being checked. Thus,
