In commercially used premises, gratings may also be used with a maximum width of apertures up to 31 mm.
4.4 Resistance of trap in mechanical closure to pressure
4.4.1 Requirements
When tested in accordance with 4.4.2, the applied pressure which just causes passage of air shall be
+10
> 200 Pa.
0
4.4.2 Test method
Mount the floor gully in a test arrangement as illustrated in Figure 3, and run water through the gully
until the trap is filled.
+10
Close the flap and set a pressure of −200 Pa by means of the bypass valves. Open the flap and fill the
0
trap with water.
Close the flap and slowly open after about 5 ± 0,5 s. Repeat this procedure until the trap no longer loses
water, but no more than 5 times.
+0,2
Remove 4 mm of water height; this corresponds to the reduction in the depth of water seal due to
0
evaporation over a period of disuse.
Apply to the outlet side a positive pressure such that flow of air just occurs. Record the pressure. Record
+10
the pressure of at least−200 Pa.
0
Note With the flap closed, set the desired negative pressure with the bypass valves, and read the manometer.
The sensors in the trap are connected to the recording device. When the flap is closed rapidly, the desired vacuum
pressure is established immediately. By reversing the fan and securing the flap in the closed position, the
arrangement can be used also for the measurement of the resistance to positive pressure.

diameter ball.
4.5.3.2 Test method
+0
Pass a rigid ball of 8 mm diameter through the floor gully, with the grating/cover removed, from the
−0,5
inlet to the outlet using gravity, only by tilting the floor gully in appropriate directions. No other force
may be applied to the ball.
4.6 Places of installation
A guide for selecting the class of a floor gully appropriate to the place of installation is given below. The
selection of the appropriate class is the responsibility of the specifier.
a) Class H 1,5: Areas where load is only expected due to maintenance.
b) Class K 3: Areas without vehicular traffic, such as dwellings, commercial and some public buildings.
c) Class L 15: Areas with light vehicular traffic, such as in commercially used premises and public areas.
All gratings shall as a minimum meet the test requirements given in 4.10.1.2 for class H 1,5. More highly
rated gratings can be used if required.

Floor gullies made of materials which are not inherently corrosion-resistant shall be protected by
corrosion prevention treatment.
4.8 Thermal behaviour of floor gullies
4.8.1 General
This test simulates use under conditions of extreme water temperatures and establishes the integrity of
the complete product.
Floor gullies shall be classified as follows:
— Class A: Application in any place of installation;
— Class B: Application restricted to bathrooms in private dwellings, with connection to outlet pipes
DN 40 to DN 75.
4.8.2 Requirements
The floor gullies and their components shall show no visible deformation or change in the components'
surface structure which could affect their fitness for use.
The floor gullies shall satisfy the requirements for tightness (4.9.1 and 4.9.2).
4.8.3 Test method
Mount the floor gully in accordance with Figure 5. Connect a suitable pipe to the outlet of the floor gully
(the outlet shall be open all the time). When different versions of the same components exist, the test
shall be done for the least favourable of their combinations.
Admit water through the grating as follows:
a) (0,5 ± 0,05) l/s of hot water at (93 ± 2) °C for (60 ± 2) s;
b) pause for (60 ± 2) s;
c) (0,5 ± 0,05) l/s of cold water at (15 ± 10) °C for (60 ± 2) s;
d) pause for (60 ± 2) s.
Repeat this cycle 1 500 times (100 h) for class A products and 360 times (24 h) for class B products.
Check to ensure that there is no deformation or change in surface texture of any component which would
impair the fitness for use.
This test does not apply to floor gullies made exclusively of metallic materials.
4.8.4 Additional test for floor gullies for use with sheet floor coverings and liquid applied
membranes
This additional test shall be applied to floor gullies intended for installation in floor constructions where
the floor covering is a watertight material. The floor covering may be connected to the floor gully by
bonding, bonding and a clamping ring combination, or by a clamping ring alone.
Mount the floor gully in the test box in accordance with the manufacturer's instructions.
Cover the entire internal surface of the box with sheet floor covering of the thickness which the floor gully
manufacturer states is the thickness for which the floor gully is designed. If the floor gully is designed for
a number of different thicknesses of sheet floor covering, it may be necessary to carry out several tests.
When applying the covering the instructions of the sheet floor covering manufacturer are to be followed.

European Foreword
This document (prEN 1253-6:2020) has been prepared by Technical Committee CEN/TC 165 “Waste
water engineering”, the secretariat of which is held by DIN.
This document is currently submitted to the CEN Enquiry.
Within its program of work, Technical Committee CEN/TC 165 requested CEN/TC 165/WG 11
“Gratings, covers and other ancillary components for use inside buildings” to prepare the following
standard:
EN 1253-6, Trapped floor gullies with a depth water seal of less than 50 mm.
The EN 1253 series under the main title Gullies for buildings will actually consist of the following parts:
— Part 1: Trapped floor gullies with a depth water seal of at least 50 mm;
— Part 2: Roof drains and floor gullies without trap;
— Part 3: Evaluation of conformity;
— Part 4: Access covers;
— Part 5: Gullies with light liquids closure;
— Part 6: Trapped floor gullies with a depth of water seal less than 50 mm;
— Part 7: Trapped floor gullies with mechanical closure;
— Part 8: Trapped floor gullies with combined mechanical closure and water seal.
Since the versions of EN 1253-1 and EN 1253-2, the most significant technical changes are the
following:
a) grouping of “Requirements” and “Test method” articles for a test;
b) adding Annex B with examples of top view of the positioning of shape of test blocks applied on the
gratings;
c) adding tolerance.

4 Design and construction
4.1 General
Floor gullies shall be capable of being connected to the pipework system covered by relevant European
Standards, and, when installed in accordance with the manufacturer's instructions, shall form an
integral part of the building. There shall be no movement possible between the body and the floor,
which would impair the functioning of the installed gully.
In areas where pressure testing of the pipe system is necessary floor gullies for use in the ground floor
shall enable such test to be performed.
The upper surfaces of frame and grating shall be flush. When in position, it shall not be possible for
gratings and covers to be dislodged from the frame, but they shall be easy to be released for e.g.
maintenance and cleaning.
Traps shall be prevented, by design features such as fixings or weights, from uncontrolled floating or
becoming displaced.
Floor gullies and their components shall be resistant to normal actions of mechanical and thermal
character.
Floor gullies may be designed without side inlet.
Floor gullies shall be delivered with installation instructions.
All pipe joints to and from the floor gully shall be designed to be watertight in accordance with EN 476.

4.2 Appearance
Internal and external surfaces shall be free from sharp edges and imperfections which could impair
functioning of the floor gully or give risk of injury.
4.3 Apertures in gratings
Apertures can be holes or slots of any shape and may also be formed between grating and frame.
By means of suitable measuring instruments or balls of suitable sizes, the dimensions of apertures in
grating shall be as specified in Table 1.

In commercially used premises, gratings may also be used with a maximum width of apertures up to 31 mm.
b
Apertures of less than 4 mm width are permitted but shall not form part of the hydraulic tests.
4.4 Resistance of water seal to pressure
4.4.1 Requirements
The applied pressure which just causes passage of air shall be > 200 Pa.
4.4.2 Test method
Mount the floor gully in a test arrangement as illustrated in Figure 3, and run water through the gully
until the trap is filled.
Close the flap and set a pressure of −200 Pa by means of the bypass valves. Open the flap and fill the
trap with water.
Close the flap and slowly open after about 5 s. Repeat this procedure until the trap no longer loses
water, but no more than 5 times.
Remove 4 mm of water height; this corresponds to the reduction in the depth of water seal due to
evaporation over a period of disuse.
Apply to the outlet side a positive pressure such that flow of air just occurs. Record the pressure.
With the flap closed, set the desired negative pressure with the bypass valves, and read the manometer.
The sensors in the trap are connected to the recording device. When the flap is closed rapidly, the
desired vacuum pressure is established immediately.
By reversing the fan and securing the flap in the closed position, the arrangement can be used also for
the measurement of the resistance to positive pressure.

4.5.2 Self-cleansing capacity
4.5.2.1 Requirements
The self-cleansing capacity of floor gullies which cannot be cleaned by removing the trap, or by an
access for cleaning in accordance with 4.5.2.1, shall be tested in accordance with 4.5.2.2.
The expelled volume of glass beads for each of the flow rates in the interval between 0,3 l/s and 0,6 l/s
shall be greater than that indicated by the straight line between the two end points 0 % at 0,3 l/s and
50 % at 0,6 l/s. Expulsion of glass beads shall commence at a flow rate less than 0,3 l/s, and at least
50 % of the glass beads shall have been expelled at a flow rate of 0,6 l/s.
4.5.2.2 Test method
Supply cold water at (15 ± 10) °C at a rate of 0,2 l/s, 0,3 l/s, 0,4 l/s and 0,6 l/s to the test box.

At each of the water flow rates, supply the floor gully, with grating/cover removed, with 200 cm of
3 3
glass beads of (5 ± 0,5) mm diameter and a density of 2,5 g/cm to 3,0 g/cm . Supply the beads at a
3
steady and uniform rate for 30 s. Continue the flow of water for a further 30 s. Measure, in cm , the
volume of glass beads that has passed through the floor gully. Conduct the test three times at each
discharge rate. The average of the three results shall be taken.
4.5.3 Anti-blockage
4.5.3.1 Requirements
Floor gullies and their components shall not be liable to clogging.
Floor gullies with gratings or covers removed shall be capable of accommodating the passage of a 8 mm
diameter ball.
4.5.3.2 Test method
Pass a ball of 8 (−0,5/0) mm diameter through the floor gully, with the grating/cover removed, from the
inlet to the outlet merely by tilting the floor gully in the appropriate directions, no other force being
applied to the ball.
4.6 Places of installation
4.6.1 General
A guide for selecting the class of a floor gully appropriate to the place of installation is given below. The
selection of the appropriate class is the responsibility of the specifier.

shall be done for the least favourable of their combinations.
Admit water through the grating as follows:
1) (0,5 ± 0,05) l/s of hot water at (93 ± 2) °C for (60 ± 2) s;
2) pause for (60 ± 2) s;
3) (0,5 ± 0,05) l/s of cold water at (15 ± 10) °C for (60 ± 2) s;
4) pause for (60 ± 2) s.
Repeat this cycle 1 500 times (100 h) for class A products and 360 times (24 h) for class B products.
Check to ensure that there is no deformation or change in surface texture of any component which
would impair the fitness for use.
This test does not apply to floor gullies made exclusively of metallic materials.
4.8.4 Additional test for floor gullies for use with sheet floor coverings and liquid applied
membranes
This additional test shall be applied to floor gullies intended for installation in floor constructions
where the floor covering is a watertight material. The floor covering may be connected to the floor gully
by bonding, bonding and a clamping ring combination, or by a clamping ring alone.
Mount the floor gully in the test box in accordance with the manufacturer's instructions.

Cover the entire internal surface of the box with sheet floor covering of the thickness which the floor
gully manufacturer states is the thickness for which the floor gully is designed. If the floor gully is
designed for a number of different thicknesses of sheet floor covering, it may be necessary to carry out
several tests. When applying the covering the instructions of the sheet floor covering manufacturer are
to be followed.
A moisture indicator is fitted to the bottom of the box at the opening where the floor gully is placed.
Admit water to the floor gully via the floor covering and grating as shown in Figure 4.
Supply water as follows:
1) (0,5 ± 0,05) l/s of hot water at (60 ± 2) °C for (60 ± 2) s;
2) pause for (60 ± 2) s;
3) (0,5 ± 0,05) l/s of cold water at (15 ± 10) °C for (60 ± 2) s;
4) pause for (60 ± 2) s.
Repeat this cycle 1 500 times (100 h).
During the test the outlet of the floor gully shall be closed when water is being supplied, and open
during pauses. Water will back up by approximately 80 mm in the box.
The outlet of the floor gully shall be connected to a pipe of 1 m length of the same DN as the outlet, laid
at a gradient of (1,5 ± 0,1) % to the horizontal.
