The "flakiness index" is retained as a term, but the test method/equipment is new and there is no correlation with the BS 812 Test which will be withdrawn. PD 6682-1 gives guidance on recommend values. The new test for "shape index" effectively replaces the BS 812 elongation test, which again will be withdrawn, and assesses the Flakiness Gauge for Classification of Aggregate Particles . Suitable Standard: Meets BS 812 . Application: For determining flakiness index. Particle is flaky when its thickness (smallest dimension) is less than 0.6 of the mid-size of the sieve fraction.
