The EN 1433 standard, published in November 2002, defines the scope of application and usage for drainage channels. It provides the definitions, determines the classes of use, the requirements for designing and testing and defines the markings and controls.

The standard defines two types of drainage channels


• Type I, which does not require any additional support to withstand vertical and horizontal service loads..

• Type M, which requires additional support to withstand vertical and horizontal service loads. It also determines the notion of contact surfaces and edges exposed to traffic, and imposes minimum values for D400 classes and higher.
 

The standard defines groups for installation locations


The accompanying document defined in appendix A-Z of the standard is available in the « Donwloads area. »
Group 1: A15 minimum
Areas that can be used only by pedestrians and cyclists.
Group 2: B125 minimum
Pavements, pedestrian areas and comparable areas, private parking lots and multi-storey car parks.
Group 3: C250 minimum
Pavement edges and non-traffic zones of hard shoulders and comparable areas.
Group 4: D400 minimum
Traffic lanes (including pedestrian streets), hard shoulders, parking lots for all types of road vehicles.
Group 5 : E600 minimum
Areas subjected to high axle loads (e.g.: ports and docks).
Group 6: F900 minimum
Areas subjected to particularly high axle loads (e.g.: surfaces for aircraft).
 

Tests


The purpose of the tests is to verify mechanical resistance and water tightness when 2 drainage channels are assembled.

Mechanical tests
The class determines a test load (for example D400 = 400 kN). Tests are performed on both elements of the system:
first of all on the grating, by measuring the permanence set after having applied 2/3 of the test load, then by applying the test load without defects.
then on the body of the mounted drain, by applying the test load (type I drainage channel without support and type M drain with support). The body of the drain must not have any defect that would undermine its ability to withstand the load.

Water tightness tests
A water tightness test is carried out with a watertight assembly of 2 drains according to the manufacturer's recommendations.
 

Markings


The standard also defines the markings that must be placed on the gratings and drain bodies. After expiry of the installation timeframe, all of drainage channels will have to marked CE.
