Specifications

What Is the Riffle Sample Divider – BS Used For?

Before most aggregate tests the laboratory sample has to be reduced to a smaller test portion that still represents it, and a riffle box does this by dividing the material between alternate slots. The sample is tipped evenly across the slots and falls into two containers, giving two halves; one half is passed through again, and the process continues until the required mass remains. Reinforced partitions keep the slot widths unchanged in use, so the division stays even, and the slot size of the unit is matched to the largest particle size. The standard listed for it is BS 812.

What to Specify When Ordering

• Quantity — the number of BS riffle dividers required.
• Size — which divider in the 7 mm to 75 mm range is required for the material to be sampled.

Frequently Asked Questions

What is the Riffle Sample Divider – BS used for?
It is used for the rapid preparation of samples, dividing a quantity of material into two representative portions that can be reduced further or tested.

What material is it made from?
The dividers are constructed of heavy gauge sheet metal, and the partitions between the slots are reinforced so that the slot dimensions do not change.

What sizes are offered?
The range covers sizes from 7 mm to 75 mm, and the size is selected to suit the largest particles in the sample to be divided.

Why are the partitions reinforced?
If the partitions bend, the slots become uneven and one side receives more material than the other; reinforcement keeps the slot widths constant so the two portions stay alike.

What does the BS in the name refer to?
The standard listed for it is BS 812, and the BS in the product name refers to this British Standard for testing aggregates.
