Gullies for buildings - Part 5: Gullies with light liquids closure

This draft European Standard specifies requirements for the design, construction, performance, application and marking as well as test methods of factory made gullies with a light liquid closure for buildings.
Light liquid closures for buildings shall be applied to avoid uncontrolled discharge of light liquids into drainage systems in case of emergency.
This draft European Standard does not apply to installations for separation of light liquids covered by EN 858-1.

Abläufe für Gebäude - Teil 5: Abläufe mit Leichtflüssigkeitssperren

Diese Europäische Norm legt Anforderungen an die Ausführung, Konstruktion, Funktion, Anwendung und Kennzeichnung sowie Prüfverfahren für werkmäßig hergestellte Abläufe mit Leichtflüssigkeitssperre für Gebäude fest.
Leichtflüssigkeitssperren für Gebäude müssen eingesetzt werden, um im Notfall das unkontrollierte Ableiten von Leichtflüssigkeiten in die Entwässerungsanlage zu verhindern.
Diese Norm gilt nicht für Abscheideranlagen für Leichtflüssigkeiten nach EN 858-1.

Avaloirs et siphons pour bâtiments - Partie 5 : Siphons avec obturateur pour liquides légers

Le présent projet de Norme européenne spécifie des exigences relatives à la conception, à la fabrication, aux performances, à l'installation, au marquage ainsi que les méthodes d'essai applicables aux siphons avec obturateur pour liquides légers fabriqués en usine et destinés aux bâtiments.
Les obturateurs pour liquides légers destinés aux bâtiments doivent être utilisés pour éviter tout rejet non maîtrisé de liquides légers dans les réseaux d'évacuation en cas d'urgence.
Le présent projet de Norme européenne n'est pas applicable aux installations de séparation des liquides légers telles que spécifiées dans l'EN 858-1.

Odtoki v stavbah - 5. del: Odtoki z zaporo lahkih tekočin

Ta osnutek evropskega standarda določa zahteve za načrtovanje, izdelavo, učinkovitost, uporabo in označevanje ter preskusne metode za tovarniško izdelane odtoke z zaporo lahkih tekočin za stavbe.
Zaporo lahkih tekočin za stavbe je treba uporabiti za preprečevanje nenadzorovanega izpusta lahkih tekočin v kanalizacijske sisteme v nujnih primerih.
Ta osnutek evropskega standarda se ne uporablja za naprave za ločevanje lahkih tekočin, zajete v standardu EN 858-1.

Overview

SIST EN 1253-5:2017 is a European Standard developed by CEN that specifies the requirements for factory-made gullies with light liquid closures used in buildings. These gullies are designed to prevent the uncontrolled discharge of light liquids-such as petrol, diesel, or fuel oil-into drainage systems during emergencies. The standard covers the design, construction, performance, application, marking, and test methods for such gullies, ensuring safety and environmental protection in building drainage systems.

This standard excludes installations intended for the separation of light liquids, which are addressed by EN 858-1. SIST EN 1253-5:2017 forms part of the EN 1253 series, focusing exclusively on gullies with light liquid closure to enhance drainage safety in buildings where light liquid contamination risk exists.

Key Topics

• Scope and Application
  EN 1253-5 targets gullies equipped with devices that automatically close when a certain level of light liquid is detected, preventing it from entering sewage and drainage systems.

• Types of Gullies

  • Type A: Gullies with integrated light liquid closure suitable for unlimited use in gravity drainage systems.
  • Type B: Gullies where the light liquid closure is an accessory, allowing a reduction in flow rate for specific applications.

• Materials
  Components in contact with light liquids or wastewater must be resistant to degradation, ensuring long-term durability and safety.

• Design and Construction Requirements

  • Inflow is only permitted through a grating on top of the gully, prohibiting inlets that might compromise the closure device.
  • The closure device must maintain a security height of at least 30 mm between the sealing and the separation line for water and light liquid.
  • Tightness requirements enforce leakage to be less than 0.1 liters per hour under test conditions.
  • Closure units should be easily removable for maintenance.

• Flow Rates
  Minimum flow rates are specified based on the nominal diameter of the gully outlet, ensuring efficient drainage without compromising the closure’s function.

• Test Methods
  Includes assessments for closure ability, tightness, and security height, ensuring compliance with performance standards.

• Marking and Identification
  Each gully and its components must bear clear, durable markings including standard reference, manufacturer details, manufacture date, certification, and product specifications for traceability and verification.

Applications

SIST EN 1253-5:2017 is essential for:

• Building drainage systems where light liquids might accidentally enter the sewage network, such as in commercial garages, fuel stations, industrial facilities, and residential buildings.
• Safety installations preventing environmental contamination by automatically sealing off light liquid spills from entering drainage infrastructure.
• Planners and engineers specifying compliant gullies to meet regulatory and environmental protection requirements.
• Manufacturers designing and producing gullies that comply with rigorous European standards for safety, performance, and durability.
• Maintenance personnel ensuring proper servicing through easy removal features of closure devices as mandated by the standard.

Related Standards

• EN 1253-1:2015 – Specifies requirements for trapped floor gullies with a water seal of at least 50 mm, forming the foundational part of the EN 1253 series.
• EN 1253-3 – Provides guidelines for the evaluation of conformity related to gullies covered in this series.
• EN 858-1 – Covers separator systems for light liquids, focusing on product design, performance, and testing of light liquid separators, which are outside the scope of EN 1253-5.

By adhering to SIST EN 1253-5:2017, stakeholders ensure optimal design and safe operation of gullies with light liquid closures, protecting drainage systems from hazardous liquid discharge and contributing to sustainable wastewater management in buildings.
