SIST EN 12207:2017

Overview

SIST EN 12207:2017 is a European Standard developed by CEN that specifies the classification method for air permeability of windows and doors. This standard applies to fully assembled windows and external and internal pedestrian doorsets made from any materials after being tested according to EN 1026. The classification is based on quantifiable air permeability test results, providing a reliable metric to assess how airtight these building components are.

This standard replaces EN 12207:1999, offering clarified procedures without changing existing classification evidence. It is mandatory for CEN member countries to adopt this standard as their national norm, ensuring harmonized air permeability classification across Europe.

Key Topics

• Scope: Classification of air permeability for windows, external and internal pedestrian doorsets after testing per EN 1026.
• Test Basis: Air permeability is measured under defined pressure differences, primarily at 100 Pa, with calculations adjusted by pressure.
• Classification Criteria:
  • Based on overall specimen area (m³/h·m²)
  • Based on length of opening joints (m³/h·m)
• Classes Defined:
  • For windows and external doors: Classes 1 to 4, with class 4 being the most airtight.
  • For internal doors: Classes A to D with D being the highest airtightness.
• Evaluation Method:
  • Average classification derived from both overall area and joint length measurements.
  • Specimens must meet minimum class requirements (class 1 or A).
  • No separate classification for positive or negative air pressure; both must be evaluated.
• Classification Report: Must include classifications based on overall area, joint length, and final combined classification.

Applications

SIST EN 12207:2017 is essential in the building and construction industry for:

• Quality Assurance: Assessing air permeability performance of windows and doors to ensure energy efficiency and ventilation control.
• Product Certification: Helping manufacturers demonstrate compliance with European air leakage standards.
• Building Regulations Compliance: Supporting the fulfillment of local or national energy codes requiring airtight building envelope components.
• Specification and Procurement: Assisting architects, engineers, and builders in selecting windows and doors with certified air permeability performance.
• Research and Development: Guiding the design improvements of windows and pedestrian doorsets to achieve better airtightness classifications.

By standardizing air permeability classification, SIST EN 12207:2017 helps reduce energy loss and improve indoor comfort by minimizing uncontrolled air leakage through building openings.
