Measurement standards have only been developed to any degree of sophistication in the US, UK and Germany. There is considerable commonality between the US and UK standards which are to be found in use throughout the world. The German standard is unlikely to be encountered outside of Germany and some other parts of Europe.

The decision on which specification to choose is usually dependant on the country of origin and there are three main floor flatness specifications used internationally.

In addition, there are two basic types of floors:

1. Free Movement Floors
   Free movement floors refer to areas where materials handling equipment operates in random, non-defined directions and have an infinite number of travel paths.
   
2. Defined Movement Floors
   Floors in very narrow aisle racking systems have materials handling equipment that runs in defined and fixed paths between the racking, such as very narrow aisles.

What is SuperFlat?

SuperFlat is the most stringent of three flatness specifications for Defined Movement Floors as stated in the UK Concrete Society's Technical Report No. 34, 2003.

A Defined Traffic path occurs when material handling equipment moves up and down the floor in precisely the same wheel position each time. Very Narrow Aisle warehouses are the most common application for defined traffic specifications.

TR34 controls three flatness properties in each classification. Two are measured parallel to the direction of travel, and the third perpendicular to.

The properties are:

1. Slope measured over two points 300mm apart.
   
2. Difference between two consecutive slopes, each measured over two points 300mm apart.
   
3. Slope measured across the vehicles wheel track.

Although described in 300mm measurements, the three properties are applied and measured continuously along the floor as they would occur to the rolling tyre of material handling equipment.
