Overview

EN 15254-3:2019, titled "Extended application of results from fire resistance tests - Non-loadbearing walls - Part 3: Lightweight partitions," is a European standard developed by CEN Technical Committee CEN/TC 127 focused on fire safety in buildings. This standard provides guidance and procedural rules for the extended application of fire resistance test results of lightweight non-loadbearing partitions.

The document specifically applies to lightweight partitions with a single steel framework, lined on both sides and optionally insulated with mineral wool. These partitions are tested according to EN 1364-1 fire resistance test protocols and classified per EN 13501-2. EN 15254-3:2019 enables variations in design parameters such as lining, metal framework, insulation, and partition dimensions to be confidently assessed without conducting new fire tests for each modification.

Key Topics

• Scope and Applicability
  Applies solely to non-loadbearing lightweight partitions consisting of a single steel frame with lining on both sides. Insulation with mineral wool within the partition cavity may or may not be present. Other types of non-loadbearing partitions covered by EN 1364-1 are excluded.

• Extended Application Principles
  Extended application predicts fire resistance performance for variations of the tested partition based on reference tests. It allows manufacturers to modify certain components or parameters while relying on prior tested fire resistance results, reducing the need for costly repeated tests.

• Parameters and Modifications Covered
  The standard details allowable modifications including:

  • Number of lining layers and dimensions (boards)
  • Orientation and position of boards
  • Thickness, shape, and dimensions of the steel framework (profiles)
  • Stud spacing adjustments
  • Mineral wool insulation density and thickness changes
  • Partition height and width increases within defined limits

• Fire Performance Classification and Limitations
  Modifications cannot increase the fire resistance classification time. Overrun time from the reference test is critical to validate any reductions in component parameters like insulation thickness or stud size.

• Use of Test Evidence
  Only owners or authorized parties of reference test data can apply the extended application procedure. Secondary test evidence can support but not replace main reference tests.

Applications

• Building Design and Construction
  Enables construction professionals and manufacturers to adapt and optimize lightweight partition systems without additional fire resistance testing, saving time and costs.

• Product Development and Certification
  Facilitates efficient product certification by allowing validated modifications. Design innovations around steel frameworks, linings, and insulation can be implemented within safety guidelines.

• Fire Safety Compliance
  Ensures that safety benchmarks are maintained while accommodating practical changes in materials or construction, assisting architects, engineers, and safety inspectors in compliance verification.

• Quality Control and Assessment
  Provides baseline criteria for assessing the impact of construction variations, ensuring fire resistance is maintained across different project conditions.

Related Standards

• EN 1364-1: Fire resistance tests for non-loadbearing elements - Part 1: Walls
  Defines fire resistance testing methods used as the basis for EN 15254-3 extended applications.

• EN 13501-2: Fire classification of construction products and building elements - Part 2
  Classification standard that interprets fire resistance test results, referenced for performance classification.

• EN 14195: Metal framing components for gypsum board systems
