Overview
EN 13501-2:2023/prA1 is a key European standard developed by CEN (European Committee for Standardization) that specifies procedures for the fire classification of construction products and building elements. Focusing on fire resistance and smoke control (excluding ventilation services), this standard plays a critical role in ensuring fire safety in buildings across Europe. It defines how products and building elements are classified based on data from fire resistance, smoke leakage/control, and mechanical tests, as well as the procedure for extended application of test results.
This amendment (prA1) updates important provisions of EN 13501-2:2023, reflecting regulatory, procedural, and terminology changes to keep pace with evolving fire safety best practices.
Key Topics
- Scope of Application: Covers a wide range of construction elements including loadbearing and non-loadbearing walls, floors, roofs, beams, columns, balconies, walkways, stairs, ceilings, partitions, facades, fire resisting doorsets, shutters, smoke control solutions, and fire protective coverings.
- Fire Resistance and Smoke Control: Specifies classification procedures based on fire resistance and smoke leakage/control tests, incorporating updated mechanical and extended application protocols.
- Exclusions: Specifically excludes ventilation services and certain lift landing doors, ensuring the focus remains on building components related to compartmentation, escape, and structural performance in fire.
- Regulatory Update: Incorporates alignment with Commission Delegated Regulation (EU) 2024/1681, ensuring fire resistance classes use consistent and regulated designation letters.
- Testing and Classification:
- References standardized fire testing and smoke control test methods.
- Stipulates procedures for expressing classification results (e.g., EI 60-S200), including aspects of extended and direct application.
- Details the classification of closing devices in fire and/or smoke conditions, and the criteria for “self-closing” (C) performance.
- Offers comprehensive rules for evaluating both single and double element products or assemblies, considering gaps, air flow rates, and the effect of seals at door thresholds.
Applications
EN 13501-2:2023/prA1 is directly applicable to a wide array of stakeholders in the construction and building safety sector:
- Manufacturers of fire-resistant construction products and systems who require harmonized classification for marketing, certification, and regulatory purposes.
- Architects, Engineers, Designers specifying compliant products for new buildings or renovations, particularly where fire compartmentation and smoke control are critical.
- Testing Laboratories and notified bodies performing fire and smoke control testing and subsequent performance classification in line with current European legislation.
- Building Regulators and Inspectors enforcing fire safety requirements in building codes and approving products for use within fire-resistant building designs.
- Specifiers and Procurement Professionals selecting products with verified fire and smoke performance credentials in line with European standards for public and private procurement.
Related Standards
EN 13501-2:2023/prA1 references and is complemented by several important related European fire and smoke test standards, including:
- EN 1634-1 & EN 1634-3: Test methods for assessing fire resistance and smoke control of doors, shutters, and windows.
- EN 15269 series: Extended application (EXAP) standards covering fire resistance and smoke control extensions for door and shutter assemblies.
- EN 17020 series: Durability for self-closing mechanisms.
- EN 12605: Mechanical test methods for industrial, commercial, and garage doors and gates.
Other relevant standards within the EN 13501 family address reaction to fire, classification of building materials, and additional aspects of fire behavior, supporting a holistic approach to fire safety in the built environment.

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"

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 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
