Footwear for firefighters
This standard specifies minimum requirements and test methods for the performance of three types of footwear for use by firefighters for general-purpose rescue, fire rescue and hazardous materials emergencies.
This standard does not cover special personal protective equipment used in high-risk situations (for example, the conditions described in ISO 15538).
Schuhe für die Feuerwehr
Diese Norm legt Mindestanforderungen und Prüfverfahren für die Leistung von drei Typen von Schuhen für
Feuerwehrleute fest: Schuhe für Brandunterdrückung, für allgemeine Nutzung im Feuerwehrdienst, Schuhe
für die Brandbekämpfung und für Gefahrstoffeinsätze.
Diese Norm gilt nicht für spezielle persönliche Schutzausrüstung für den Einsatz in Situationen mit sehr
hohem Risiko (z. B. Bedingungen nach ISO 15538).
ANMERKUNG Die Auswahl des Typs von Schuhen für Feuerwehrleute (siehe 4.3 und Tabellen 3 und 4) sollte nach
einer umfassenden Risikobewertung erfolgen (siehe Anhang A).
Chaussures pour pompiers
La présente norme fixe les exigences minimales et les méthodes d’essai permettant de déterminer les performances de trois types de chaussures destinées aux pompiers, dans le cadre de l’extinction d’un feu, d’opérations générales de sauvetage, de la lutte contre les incendies et de situations d’urgence en présence de matériaux dangereux.
La présente norme ne traite pas des équipements de protection individuelle spéciaux utilisés dans les situations à niveau de risque élevé (par exemple, dans les conditions décrites dans l’ISO 15538).
NOTE 1 Il convient que le choix du type de chaussures (voir en 4.3 et dans les Tableaux 3 et 4) pour pompiers soit fait à la suite d’une évaluation complète des risques (voir l’Annexe A).
Obutev za gasilce
Ta evropski standard določa najmanjše zahteve in preskusne metode za zmogljivosti treh vrst (glejte 4.3) obutve za gasilce za gašenje ognja, splošno reševanje, reševanje iz ognja in nujne primere, ki vključujejo nevarne materiale. Ta evropski standard ne zajema posebne osebne varovalne opreme, ki se uporablja v situacijah z visokim tveganjem (na primer pod pogoji, opisanimi v standardu ISO 15538). Glavne razlike med to izdajo in izdajo EN 15090:2006 so naslednje: a) Dodana je odpornost proti zdrsu (sklicevanje na EN ISO 20345, 5.3.5). b) Vrste obutve za gasilce (4.3) so bile spremenjene v skladu s tveganji. c) Zahteve in preskusne metode za toplotno sevanje (6.3.2 in 7.2) so bile spremenjene. d) Zahteva v zvezi z odpornostjo na kemikalije (6.5) je bila delno spremenjena. e) Zahteve za zunanje podplate z visoko električno odpornostjo (6.6.4 v stari različici) in ustrezni znaki iz tabele 9 so bili odstranjeni. f) Dodatek B (normativen) je bil prestrukturiran. Merila za oceno stanja obutve so našteta ločeno: »Izolacija pred toploto«, »Toplotno sevanje« in »Odpornost proti plamenu«. g) Dodatek D »Preskušanje vezalk« je bil izbrisan.

EN 15090:2012 (E) 5 Introduction The purpose of this standard is to provide minimum performance requirements and test methods for footwear for firefighters which is intended for use for fire fighting and associated activities. A risk assessment should be used to determine whether the footwear covered by this standard is suitable for the intended use for the expected exposure. Firefighters should be trained in the use, care and maintenance of the footwear covered by this standard, including an understanding of its limitations. SIST EN 15090:2012
EN 15090:2012 (E) 6 1 Scope This European standard specifies minimum requirements and test methods for the performance of three types (see 4.3) of footwear for use by firefighters for fire suppression, general-purpose rescue, fire rescue and hazardous materials emergencies. This European standard does not cover special personal protective equipment used in high-risk situations (for example, the conditions described in ISO 15538). 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

Description Class I Footwear made from leather and other materials, excluding all-rubber or all-polymeric footwear Class II All-rubber (i.e. entirely vulcanized) or all-polymeric (i.e. entirely moulded) footwear
4.2 Design Footwear shall conform to one of designs B to E of Figure 3 of EN ISO 20345:2011.
4.3 Type The types of footwear for firefighters shall be as follows: Type 1: Outdoor interventions, fire and wildland firefighting; no protection against penetration, no toe protection, no protection against chemical hazards; Type 2: All fire suppression and rescue interventions where protection against penetration, and toe protection are needed, no protection against chemical hazards; Type 3: All fire suppression and rescue interventions where protection against penetration and toe protection are needed, including protection against chemical hazards. 5 Sampling and conditioning The minimum number of samples shall be that specified in Clause 6 of EN ISO 20344:2011, together with the minimum number of test pieces taken from each sample, as given in Table 2. Wherever possible, test pieces shall be taken from the whole footwear unless otherwise stated in this standard and in EN ISO 20344. If it is not possible to obtain a large enough test piece from the footwear, then a sample of the material from which the component has been manufactured may be used instead and this shall be noted in the test report. Where samples are required from each of three sizes, these shall comprise the largest, smallest and a middle size of the footwear under test. All test pieces shall be conditioned in a standard atmosphere of (23 + 2) °C and (50 + 5) % relative humidity for a minimum of 48 h before testing, unless otherwise stated in the test method. The maximum time which shall elapse between removal from the conditioning atmosphere and the start of testing shall be not greater than 10 min, unless otherwise stated in the test method. Each test piece shall individually satisfy the specific requirement, unless otherwise stated in the test method. NOTE The uncertainty of measurement for each test method described in the present standard may be assessed. One of the two following approaches should be used:
− a statistical method, e.g. that given in ISO 5725-2 [20]; SIST EN 15090:2012
EN 15090:2012 (E) 8 − a mathematical method, e.g. that given in ENV 13005 [3]. Table 2 — Minimum number of samples and test specimens or test pieces Property to be determineda Reference Number of samples Number of test pieces from each sample Test only on the final footwear Radiant heat 6.3.2

The applicability of a requirement to a particular classification is indicated in the table by the following: X means that the requirement has to be met. In some cases the requirement relates only to particular materials within the classification, e.g. value of leather components. This does not mean that other materials are precluded from use. O means that if the component parts exists, the requirement shall be met: - means not allowed * means that if the property is claimed, the requirement given in the appropriate clause shall be met. x means that one of the three requirements shall be chosen. N/A means the requirement is not applicable. The absence of X, -, or O means that no requirement is made. SIST EN 15090:2012
