Brick size, Dimension test for Standard brick

Determine the Standard brick size in mm (Length, Width and Height) as per Standard. Tolerance of brick size Visual Examination for brick dimension.

Test Standard : IS 1077-199, Reaffirmed 2011

Test Appratus : A steel tape.

Test Procedure :

  1. Selected random 20 Nos of bricks for testing.
  2. Examine for surface defects like cracks, flaws and nodules of free lime.
  3. Take twenty brick sample. Remove all blisters, loose particles, clay and small projections from brick.
  4. Arrange all brick lengthwise in contact with each other and in a straight line at a level surface.
  5. Measure overall length of the assembled bricks a steel tape.
  6. Measure width and height of assembled bricks.
