Overview

EN 13501-2:2023/prA1 is a CEN amendment to the European classification standard for fire performance of construction products and building elements. It defines the procedure to generate fire classifications using data from fire resistance tests, smoke control/air flow tests and applicable mechanical tests - excluding products used in ventilation systems. The standard covers direct and extended application of test results and clarifies classification formats used across a wide range of building elements.

Key topics and requirements

  • Scope of products and elements: loadbearing and non-loadbearing walls, floors, roofs, beams, columns, balconies, walkways, stairs, partitions, facades (curtain walls), ceilings, raised floors, chimneys, penetration/linear joint seals, service ducts/shafts, air transfer grilles, fire-resisting doorsets and shutter assemblies, smoke control doorsets, conveyor closures and wall/ceiling coverings.
  • Classification basis: uses measured data from fire resistance tests and/or smoke control (air flow) tests and relevant mechanical tests within the direct field of application of the referenced test method. Extended application of test results (EXAP) is included.
  • Smoke control (S) classification updates: clarifies air flow terminology and provides S-class variants (e.g., S200, S200L, Sa3, Sa4) including thresholds. Example thresholds in the amendment: maximum air flow limits of 20 m3/h for single-leaf and 30 m3/h for double-leaf doorsets; 50 m3/h option for large industrial doorsets (>9 m2 leaf area). S-class indicators (3 or 4) denote whether the bottom gap was taped during testing.
  • Doorsets and closing devices: specific provisions for testing and classifying fire doorsets, shutter assemblies and openable windows (tests per EN 1634-1 and EN 1634-3). Self-closing durability and extended application references include EN 15269 and EN 17020 series; operability/closing tests reference EN 16034.
  • Classification procedure: detailed requirements for test evidence, test report identification and how classifications (e.g., E, EI, REI plus S and C indicators) are expressed, including inside/outside exposure markers (i→o, o→i, i↔o).

Applications and users

This standard is essential for:

  • Manufacturers of construction products and fire-rated building elements who need harmonized fire classification
  • Notified test laboratories and certification bodies preparing classification reports
  • Fire safety engineers, architects and specifiers selecting assemblies for compliance with building regulations
  • Contractors and façade/doorset suppliers implementing extended application (EXAP) of test evidence

Related standards (examples)

  • EN 1634-1, EN 1634-3 (doorset fire and smoke tests)
  • EN 16034 (operability and self-closing)
  • EN 15269, EN 17020 (extended application / EXAP and durability)
  • EN 12605 (mechanical test methods for industrial/commercial doors)

Keywords: EN 13501-2:2023/prA1, fire classification, fire resistance, smoke control, doorsets, construction products, EXAP, fire safety compliance.

This document is currently submitted to the CEN Enquiry.
1 Modification to “Introduction”
Replace
“CEN, CENELEC and EOTA committees preparing technical specifications which contain performance
requirements against fire resistance tests are expected to refer to the fire resistance classification given
in this document and not refer directly to any specific fire test method.”
with
“Commission delegated regulation (EU) 2024/1681 of 6 March 2024 specifies performance and classes
regarding fire resistance. These classes are identified by designation letters, each of which refers to an
important characteristic of fire resistance behaviour.”
2 Modification to Clause 2, "Normative References"
Replace
“EN 12604, Industrial, commercial and garage doors and gates — Mechanical aspects — Requirements and
test methods”
with
“EN 12605: 2000, Industrial, commercial and garage doors and gates —Mechanical aspects — Test
methods”

Replace the word “doors” with “doorsets” throughout Clause 4.
In clause 4.6 bullet point 1 replace “leakage” with “air flow”.
In clause 4.6 bullet point 2 replace “leakage” with “air flow”.
At end of section 4.6 add the following note:
“NOTE Instead of air flow rate, the term leakage rate was used to describe the evaluation of ambient and medium
temperature for smoke control doorsets in former versions of this document.”
4 Modification to Clause 5, "Resistance to fire performance characteristics"
In clause 5.1, at end of second sentence, add “/control” after “smoke leakage”.

“S is the classification related to the air flow rate at ambient temperature and in the case the doorset
a3
was tested with the bottom gap taped over.
S is the classification related to the air flow rate at ambient temperature and in the case the doorset was
a4
tested without the bottom gap taped over.
S is the classification for the air flow rate at both ambient temperature and at 200°C.
S is the classification for the air flow rate at both ambient temperature and at 200°C and may be used
200L
for large industrial doorsets only. Large industrial doorsets have an overall door leaf area of more than
9m .
NOTE 1 The classification S is defined in previous versions of this document.

In clause 6.6.2 replace the text for S definition with the following:
“for elements with particular limitations on smoke leakage/control;
For fire resistant elements the S shall be added to the fire resistance classification (e.g. EI 60-
S ). Where no fire resistance classification is relevant, the element shall simply be classified S
as defined in this document for the particular product and classification;”
6 Modification to Clause 7, "Classification procedure for fire resistance”
In clause 7.1.1 a) “load level (see 3.26)” is to be a separate bullet point
In clause 7.1.1 c) replace the word “doorsests” with “doorsets”.
In clause 7.1.1 d) add “/control” after “smoke leakage” and “/air flow” after “limiting leakage” and before
“rate”.
In clause 7.2.2.3 replace the word “both” with “one”.
In section 7.3.2.4 move “With external fire exposure, the classification shall be given as REI 30-ef, or
REI 60-ef (o→i).” to the end of the paragraph above.
nd
In table 4 in clause 7.3.4.4 delete the 10-minute classification column (2 column) for both RE and REI.
In clause 7.5.2.1 delete “EN 15254-6 and”.
In clause 7.5.2.2 delete “and EN 15254- 6” and insert “EN 15254-3” between “EN 15254-2” and “EN 15254-
4”, and insert “and” between “EN 15254-4” and “EN 15254
