Overview

SIST EN 1253-4:2016 is a European Standard developed by CEN that specifies requirements for access covers used in drainage systems inside buildings. This standard classifies access covers based on their loading strength and outlines specifications related to design, construction, marking, testing, and conformity evaluation. It is part of the EN 1253 series, which comprehensively addresses gullies for buildings, including trapped floor gullies and roof drains.

Importantly, SIST EN 1253-4:2016 applies exclusively to internal building drainage access covers, and excludes those intended for external use, which fall under the EN 124 series.

Key Topics

• Classification by Loading Strength
  Access covers are categorized based on their ability to withstand loads, with classes ranging from H 1.5 (no load expected) to P 400 (extra-heavy industrial use). This classification ensures the right type of cover is selected for specific environments such as residential areas, commercial premises, industrial sites, or heavy-duty zones for forklift or vehicular traffic.

• Design and Construction Requirements

  • Access covers must feature compatible frame and cover design to prevent dislodgement yet allow ease of opening.
  • Surfaces must be flush and free from sharp edges or defects to ensure safety and functionality.
  • Special edge protection is required for reinforced concrete covers using galvanized steel or equivalent materials.

• Tightness Classes
  The standard defines three tightness classifications for access covers:

  • Watertight (Class Wt): Prevents ingress of surface water without hydrostatic pressure.
  • Odourtight (Class Ot): Stops foul air from escaping.
  • Backflow tight (Class Bt): Prevents water backflow under pressure up to 50 kPa, ensuring watertightness and odourtightness as well.

• Testing and Evaluation
  Access covers must undergo rigorous testing to verify load capacity, tightness, appearance, and dimensional accuracy. Conformity evaluation follows EN 1253-3 procedures to certify compliance.

• Marking Requirements
  Covers and frames should have visible, durable markings including the standard reference (EN 1253-4), load and tightness class, manufacturer’s identification, certification bodies when applicable, and manufacture date. Proper marking ensures traceability and standard compliance.

Applications

SIST EN 1253-4:2016 applies broadly within internal building environments for drainage system access covers, with key applications including:

• Residential Buildings: Selection of lower load classes (H 1.5, K 3) for non-vehicular, pedestrian areas such as dwellings and apartments.
• Commercial Premises: Medium load classes (L 15, R 50) suitable for areas with light vehicular traffic or public walkways.
• Industrial Facilities: Use of higher load classes (M 125, N 250, P 400) for environments exposed to heavy machinery, forklifts, and vehicle movement in warehouses, factories, and food processing plants.
• Safety-Critical Areas: Access covers designed with odour and backflow tightness to prevent environmental contamination and ensure hygiene in sanitary systems.

By adhering to SIST EN 1253-4:2016, specifiers and manufacturers can ensure access covers meet safety, durability, and functionality requirements critical to efficient drainage operations within buildings.

Related Standards

SIST EN 1253-4:2016 is part of the wider EN 1253 series and references several essential standards:

• EN 1253-1:2015: Trapped floor gullies with a water seal of at least 50 mm.
• EN 1253-2:2015: Roof drains and floor gullies without traps.
• EN 1253-3: Procedures for evaluation of conformity of gullies and access covers.
• EN 124 series: Covers and gully tops for vehicular and pedestrian areas, applicable to external use only.
• EN 476: General requirements for components used in drains and sewers.

These interconnected standards provide a comprehensive framework ensuring standardized, reliable drainage system components across European markets.
