Overview

EN 13501-2:2023 specifies how to classify construction products and building elements using data from fire resistance and/or smoke control tests (ventilation services excluded). It updates and replaces the 2016 edition and defines the procedure to convert test results - including relevant mechanical tests and extended application of test data - into harmonized fire resistance and smoke-control classes used across Europe. The standard applies to a wide range of loadbearing and non-loadbearing elements, protective systems and wall/ceiling coverings.

Key topics and technical requirements

• Scope of classification: Classification is based on fire resistance tests, smoke leakage/control tests and directly related mechanical tests. Extended application of test results is included where justified.
• Covered elements: Includes (but is not limited to)
  • Loadbearing elements without fire-separating function: walls, floors, roofs, beams, columns, balconies, walkways, stairs
  • Loadbearing elements with fire-separating function: walls, floors, roofs, raised floors
  • Protection systems: ceilings without independent fire resistance, protective coatings, claddings, screens
  • Non-loadbearing elements: partitions, facades (curtain walls), ceilings with independent resistance, raised floors, fire doorsets, smoke control doorsets, conveyor closures, penetration and linear joint seals, service ducts/shafts, air transfer grilles, chimneys
  • Wall and ceiling coverings with fire protection ability
• Performance characteristics: The standard addresses resistance performance designations such as R (loadbearing), E (integrity), I (insulation), W (radiation), M (mechanical), C (self‑closing), S (smoke control), O, G, K, plus classification periods and designatory letters.
• Classification procedure: Rules for test selection, number of required tests, field of application, combinations of classes, and presentation/declaration of classification are provided. Normative test methods referenced are listed in Clauses 2 and 7.
• Exclusions/clarifications: Ventilation services are excluded. Lift landing doors tested to EN 81‑58 are excluded; if tested per EN 1634‑1 they are classified under the relevant clause.

Practical applications and users

EN 13501-2:2023 is essential for:

• Manufacturers of construction products and fire‑protection systems who need harmonized fire performance classification for product documentation and CE marking.
• Fire testing laboratories and certification bodies applying test results to produce classification reports.
• Architects, fire safety engineers and specifiers selecting elements that meet project fire performance requirements.
• Building control authorities and consultants verifying compliance with building codes and national fire safety regulations.

Introduction
The aim of this document is to define a harmonized procedure for the classification for fire resistance
of construction products and building elements. This classification is based on the test procedures
listed in Clause 2 and the relevant field of application procedures.
This document is prepared in support of the second basic requirement for construction works, in the
REGULATION (EU) No 305/2011 OF THE EUROPEAN PARLIAMENT AND OF THE COUNCIL of 9 March
2011 and is detailed in the Interpretative Document number 2 (ID2): Safety in case of fire (OJC62 Vol
37). It reflects the Commission Decision (EU) 2000/367/EC of 3 May 2000 amended by 2003/629/EC
of 27 August 2003 and 2011/232/EC of 11 April 2011 as regards the classification of the resistance
to fire performance of construction products, construction works and parts thereof.
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.
This document has been prepared under a Standardization Request given to CEN by the European
Commission and the European Free Trade Association.
This document provides for a common understanding for these requirements. It interprets the
functional requirements for the different groups of building elements and explains the method for
deriving their classification on the basis of test results (Direct field of application) and/or extended
application results for individual elements.
NOTE Test reports constitute the basis for extended application reports as explained in EN 15725.

1 Scope

elements using data from fire resistance and/or smoke leakage/control tests and/or mechanical tests
which are within the direct field of application of the relevant test method. Classification on the basis
of extended application of test results is also included in the scope of this document.
This document deals with:
a) loadbearing elements without a fire separating function:
— walls;
— floors;
— roofs;
— beams;
— columns;
— balconies;
— walkways;
— stairs;
b) loadbearing elements with a fire separating function, with or without glazing, services and
fixtures:
— walls;
— floors;
— roofs;
— raised floors;
c) products and systems for protecting elements or parts of the works:
— ceilings with no independent fire resistance;
— fire protective coatings, claddings and screens;
d) non-loadbearing elements or parts of works, with or without glazing, services and fixtures:
— partitions;
— facades (curtain walls) and external walls;
— ceilings with independent fire resistance;
— raised floors;
— fire resisting doorsets, shutter assemblies and openable windows and their closing devices;
— smoke control doorsets and shutter assemblies and their closing devices;
— conveyor systems and their closures;
— penetration seals;
— linear joint seals;
— combined penetration seals;
— service ducts and shafts;
— air transfer grilles;
— chimneys;
e) wall and ceiling coverings with fire protection ability;
f) lift landing doors which are tested according to EN 81-58 are excluded from this document. Lift
landing doors which are tested in accordance with EN 1634-1 are classified in accordance with
7.5.5.
Relevant test methods which have been prepared for these construction products are listed in
Clauses 2 and 7.

4 Fire scenarios
4.1 General
The second basic requirement for construction work of the Construction Products Regulation
addresses e.g. spread of fire and smoke and the loadbearing capacity of the construction. These
requirements are considered to be satisfied by proving fire resistance of loadbearing and/or
separating elements.
Fire resistance of loadbearing and/or separating elements shall be assessed using one or more of the
levels of thermal attack given in 4.2 to 4.6. Further clauses of this document identify which attack(s)
shall be used for which elements.
NOTE 1 The various levels of thermal action given in 4.2 to 4.6 reflect different fire scenarios and the
standards which prescribe their translation into practical tests give tolerances for their application.
NOTE 2 Other heating curves exist, for example the hydrocarbon curve. Also, for extreme fire scenarios (e.g.
traffic tunnels, nuclear plants), more severe conventional curves can be specified. These are not, however, used
for the classification of elements according to this document.
4.2 The standard temperature/time curve (post flash-over fire)
When applied as a basis for testing, the standard temperature/time relationship shall be applied for
the full duration of the test. The relationship, which is a model of a fully developed fire in a
compartment, is given by the following relationship:
T = 345 log (8t +1) + 20 (1)
where
t is the time from the start of the test in minutes (min);
T is the mean furnace temperature in degrees Celsius (°C).
NOTE Further details relating to the practical application of this curve and other test parameters,
e.g. tolerances, are given in EN 1363-1.
4.3 The slow heating curve (smouldering fire)
The smouldering fire test shall only be used if it is expected that the fire resistance performance of
the element may be reduced by exposure to temperatures associated with the growth stage of a fire.
It is, therefore, particularly relevant to elements whose performance may be dependent upon high
heating rates below approximately 500 °C (as provided during the standard temperature/time curve)
for achievement of their classifications (i.e. mainly reactive or intumescent products).
The slow heating curve is given by the following relationship:
for 0 < t ≤ 21
0,25
T 154t+ 20 (2)
for t > 21
T 345log 8 t− 20++1 20 (3)
( ( ) )
where
t is the time from start of test in minutes (min);
T is the mean furnace temperature in degrees Celsius (°C).
NOTE Further details relating to the practical application of this curve, and other test parameters
e.g. tolerances, are given in EN 1363-2.
4.4 The ‘semi-natural’ fire
During the ‘semi-natural’ fire test the temperature of the fire gases adjacent to the soffit of the ceiling
shall reach 1 000 °C within 10 min to 20 min of the start of the test.
Because of the difficulties in achieving the necessary thermal attack in a conventional furnace, the
attack shall be provided by fire from wooden cribs made from softwood.
NOTE 1 The ‘semi-natural’ fire is a fire which produces direct flame impingement with a high convective heat
transfer content which is not realized in furnace tests using the standard temperature/time curve. The term
‘semi-natural’ fire corresponds to the single burning item exposure required for ceilings in 4.3.1.3.4 (a) of the
Interpretative Document 2 (not to be confused with the “single burning item” test for reaction to fire). It is
relevant only for lightweight suspended horizontal protective membranes having a low thermal inertia.

=
NOTE 2 Further details relating to the practical application of this thermal attack, and other test parameters,
are given in EN 13381-1.
4.5 The external fire exposure curve
This is a temperature/time relationship which represents the exposure of the external face of a wall
to fire which may emerge from a window of a building, or from a free-burning external fire.
The curve is defined by the relationship:
-0,32t -3,8t
T = 660 (1-0,687e – 0,313e ) + 20 (4)
where
t is the time from start of test in minutes (min);
T is the mean furnace temperature in degrees Celsius (°C).
NOTE Further details relating to the practical application of this curve, and other test parameters e.g.
tolerances, are given in EN 1363-2.
4.6 Constant temperature attack
In addition to the heating regimes given above, the evaluation of some elements shall be made using
a notional constant value of temperature. The specified temperature depends upon the type of
element. The rate at which this temperature is achieved is specified in each relevant test standard.
The following temperatures shall be used for the elements indicated:
— 20 °C for evaluating the leakage rate of smoke control doors at ambient temperature;
— 200 °C for evaluating the leakage rate of medium temperature smoke control doors;
— 500 °C for evaluating the fire performance of raised floors;
— 1 000 °C for evaluating soot fire resistance of chimneys and chimney related products.
— Test temperatures depending on declared temperature class according EN 1443:2019, Table 2
for evaluating thermal resistance of chimneys and chimney related products or the relevant
product standard and for chimney components according to the appropriate dependent product
standard. The nominal working temperature shall be tested according to
