Used to determine if aggregate particles are to be considered flaky, i.e. their thickness is less than 0.6 of their nominal size. Each sieve is made from heavy gauge steel. To evaluete the thickness and the elongation index of the aggregates particles, thickness gauge code 47-D0540 and length gauge code 47-D0541 can be used.
