Tere.
Saadame infoks, vastust ei ole vaja saata.
Aastate jooksul oleme täheldanud Päästeameti töös (piirdetarindite
normatiivdokumentide loome valdkonnas) stagneerumist. Mingeid märke, et
ametnikke huvitaks teatud euroopalike tehniliste põhimõtete
harmoniseerimine Eestis pole näha. Sellekohane kriitiline telesaade on ka
eetris olnud. Balti Päästeametnike foorumitel puuduvad Eesti esindajad.
Eesti Päästeamet ei tunne mingit huvi Euroopa juhtivate
tulekaitsespetsialistide tasuta täiendõppekoolituste vastu Eestis.
Eesti stagneerunud regulatsioonide tõttu pole osaliselt võimalik
rakendada Euroopas levinuid tehnilisi lahendusi (fassaadid, katused,
passiivsed tulekaitsemeetmed metallile ja puidule). Sellekohastele
tähelepanu juhtimistele tavaliselt ei reageerita. Kui üldse on võimalik
kellegagi kontakti saada, siis teatatakse, et Päästeamet töötab Eestis
kehtiva seaduste raames.
Situatsiooni tunnetavad enamus piirdetarindite ja metall- ning
puitkonstruktsioonide projekteerijaid. Meie kohalik olukord on silma
hakanud ka Euroopa suurriikides, vastav kiri rahvusvaheliselt
kontsernilt lisas ja manuses
Eesti on otsustanud piirdetarindite ja metall- ning puitkonstruktsioonide
tulekaitse regulatsioonide valdkonnas ülejäänud Euroopast eraldi käia.
Selle iseseisvaks loomiseks puudub aga vastav insener-tehniline
võimekus, mistõttu normatiivdokumendid on kohati süsteemitud ja auklikud.
Lisaks on olukord protektsionistlik, kui euroopalikke lahendusi ei ole
võimalik lokaalsete bürokraatlike barjääride tõttu rakendada.
Kaotajaks on Eesti kodanikud.

Dear all,
Time by time I am getting inquiries from Estonian companies with such
cases (see example below)
* 1st example. I have x solution which has fire class of EI60 but the
requirement is EI120, so they think that EI60 + EI60 and total we will
have EI120.
* 2nd example. I have a requirement for EI180. The client is saying
that I have already a concrete wall which is EI60 + if I add maybe
mineral wool it will be EI120 so Linas give me the solution for wall only
for fire requirement EI60 because after sum up we will have EI180.
Colleagues, it cannot be like that, it is ridiculous, it is not
professional, such project should not be submitted and cannot be
discussed. If you have such inquiries then please send the letter which
we prepared (see attached file).
I send already a letter to Estonian rescue board because these kind of
inquiries are coming only from Estonia and I assume on many cases somehow
it is accepted. If its accepted it means that the technical supervisor or
fire expert are not professional and dont have the competences to work in
such field.
Note: in a simple words if there is a requirement on X solution for EI120
it means you should test for EI120, if you have for EI180 it means you
have to test for EI180 and you cannot sum up!

Ref: fire protection of steel structure
Promat is an international company with over 60 years of experience in passive
fire protection. During these years, we have carried out thousands of fire tests in
accredited laboratories around the world.
Fire tests in Europe (also in Estonia) are carried out in accordance with European
Standards created by CEN. Fire tests simulate the physicochemical conditions of a fire.
There is no European standard that allows for the possibility of "adding up" the fire
resistance of individual tested elements, even if they are built in series.
Fire resistance is not a linear function. It cannot be concluded that if the thickness
of the protection is doubled in a given solution, the fire resistance will be doubled. One
of the reasons for this is the heating process inside the furnace. In accordance with
EN1363-1 (Fire resistance tests - Part1: General requirements), the standard
temperature /time curve is as follows:
Where T - temperature ° C
t - time in minutes
The temperature conditions are different in the first hour of the test compared to
the second or third hour of the test.
If there is a requirement for protection with EI120 fire resistance, then a solution
with this fire resistance should be used, not two times EI60 solutions built in series.
Sincerely,
Magdalena Stuczka-Sidor
