European foreword
This document (EN 13501-2:2023/prA1:2025) has been prepared by Technical Committee CEN/TC 127
“Fire safety in buildings”, the secretariat of which is held by BSI.
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”
3 Modification to Clause 4, "Fire Scenarios"
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”.
In clause 5.2.2.1 in second sentence of first paragraph replace “may” with “can”
In clause 5.2.3.3 replace the word “doorsests” with “doorsets”.
In clause 5.2.4 in the last sentence replace “thermal insulation” with “radiation”
In clause 5.2.7, after the first sentence, delete all text and replace with the following:
“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 2 The classification S is defined in previous versions of this document.”

5 Modification to Clause 6, "Classification of characteristics related to fire
resistance performance”
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
