Glass in building - Security glazing - Testing and classification of resistance against explosion pressure

This European Standard specifies a test method, performance requirements and classification for explosion pressure resistant glazing for use in buildings.
The explosion pressure resistant glazing is intended to offer resistance against explosives with respect to human safety.
This European Standard concerns a method of test against blast waves generated using a shock tube or similar facility to simulate a high explosive detonation.
The classification is only valid for tested glass sizes of about 1 m2. Based on theoretical considerations and/or experimental work, the results can be used for estimating the explosion-pressure-resistance of other glass sizes.
NOTE 1   The resistance classes are not assigned to specific situations. For each individual case the individual who specifies, if necessary with the help of experts in the field of explosion, should be consulted.
NOTE 2   The protection provided by explosion-resistant-glazing not only depends on the product itself, but also on the design and fixing of the glass.

Glas im Bauwesen - Sicherheitssonderverglasung - Prüfverfahren und Klasseneinteilung des Widerstandes gegen Sprengwirkung

Diese Europäische Norm legt ein Prüfverfahren, Leistungsanforderungen und die Klasseneinteilung von sprengwirkungshemmenden Sicherheitssonderverglasungen für das Bauwesen fest.
Die Hauptanforderung an sprengwirkungshemmende Verglasungen ist es, Menschen gegen Explosionsdruck-wellen zu schützen.
Diese Europäische Norm beschreibt ein Verfahren zur Prüfung der sprengwirkungshemmenden Eigenschaften von Ver¬glasungen, bei denen der erforderliche Druckstoß in einem Stoßrohr oder einer ähnlichen Einrichtung erzeugt wird, um die Detonation einer Sprengladung nachzuahmen.
Die Klasseneinteilung gilt nur für die geprüften Verglasungsgrößen von etwa 1 m2. Aufgrund theore¬tischer Über¬legungen und/oder experimenteller Erkenntnisse können die Ergebnisse jedoch für Aussagen über die Sprengwirkungshemmung anderer Verglasungsgrößen verwendet werden.
ANMERKUNG 1   Die Widerstandsklassen sind nicht speziellen Anwendungsfällen zugeordnet. In jedem Einzelfall sollte der Planer, gegebenenfalls unterstützt durch Sprengstoffexperten, hinzugezogen werden.
ANMERKUNG 2   Der Schutz durch sprengwirkungshemmende Verglasungen hängt nicht nur vom Erzeugnis selbst, sondern auch vom Aufbau und Einbau des Glases ab.

Verre dans la construction - Vitrage de sécurité - Mise à essai et classification de la résistance à la pression d'explosion

La présente norme européenne spécifie une méthode d'essai, des exigences de performance et la classification des vitrages résistant à la pression des explosions utilisés dans le bâtiment.
Les vitrages résistant à la pression des explosions sont destinés à résister au souffle d'explosions en vue d'assurer la sécurité des personnes.
La présente norme européenne traite d'une méthode d'essai contre les ondes de choc engendrées par un tube à onde de choc ou un dispositif similaire simulant une détonation à haut pouvoir explosif.
La classification n'est valable que pour des dimensions de vitrage d'essai d'environ 1 m2. Les résultats correspondants peuvent être utilisés pour une appréciation de la résistance à la pression des explosions d'autres dimensions de vitrages en s'appuyant sur des considérations théoriques et/ou des travaux expérimentaux.
NOTE 1   Les classes de résistance ne sont pas conçues pour des situations spécifiques. Pour chaque cas particulier, il convient de consulter le demandeur, si nécessaire avec l'aide d’experts dans le domaine de l'explosion.
NOTE 2   La protection apportée par un vitrage résistant à la pression des explosions ne dépend pas uniquement du produit lui-même, mais également de la conception et du mode de fixation du vitrage.

Steklo v gradbeništvu - Varnostna zasteklitev - Preskušanje in razvrščanje odpornosti proti zvočnemu tlaku pri eksploziji

Ta evropski standard določa preskusno metodo, zahtevane lastnosti in razvrščanje za zasteklitev, odporno proti zvočnemu tlaku pri eksploziji v gradbeništvu. Zasteklitev, odporna proti zvočnemu tlaku pri eksploziji, je namenjena zagotavljanju odpornosti proti eksplozijam, da se zagotovi varnost ljudi. Ta evropski standard zajema preskusno metodo za ugotavljanje odpornosti proti udarnim valovom, ki nastanejo pri uporabi detonacijskih cevi ali podobnih naprav za simulacijo izjemno eksplozivne detonacije. Klasifikacija je veljavna le za preskušene velikosti stekla s površino približno m2. Rezultati se lahko na podlagi teoretičnih predpostavk in/ali poskusov uporabljajo za oceno odpornosti stekla drugih velikosti proti zvočnemu tlaku pri eksploziji.

Overview

EN 13541:2012 - "Glass in building - Security glazing - Testing and classification of resistance against explosion pressure" is a CEN European Standard that defines a laboratory test method, performance requirements and a classification system for explosion pressure resistant glazing (blast-resistant/security glazing) used in buildings. The standard specifies shock-tube based blast testing to simulate high-explosive detonation effects, and assigns classes (ER1–ER4) based on the reflected peak overpressure, positive specific impulse and overpressure duration.

Key topics and technical requirements

• Scope: Test method and classification for glazing intended to protect human safety against explosive blast loads; classification is valid for tested glass sizes of about 1 m².
• Test method: Use of a shock tube or similar device to generate a plane shock wave normal to the specimen’s attack face to simulate a spherical detonation.
• Classification basis: Maximum reflected overpressure (Pr), positive specific impulse (i+) and duration of the positive overpressure phase (t+). Four classes (ER1 to ER4) are defined with increasing load levels.
• Specimen requirements:
  • Nominal dimensions: 1100 × 900 mm (± 5 mm).
  • Sample size: three test pieces per attack face and per class (one extra recommended for transport damage).
• Performance criteria:
  • No through-holes allowed after test.
  • No openings between frame and specimen that penetrate full thickness.
  • Test pieces achieving a class automatically achieve all lower classes.
  • Optional notation S/NS to indicate splintering (S) or no splintering (NS) of the protected rear face.
• Test apparatus and conditions:
  • Rigid specimen holder, clamped on all edges over (50 ± 10) mm with rubber strips (50 ± 2 mm × 4 ± 1 mm; 50 ± 10 IRHD).
  • Clamping pressure: (14 ± 3) N/cm².
  • Specimen temperature: surface/mass (18 ± 5) °C; stored at this temperature ≥12 h prior to test.
  • Measuring devices must determine reflected overpressure-time history with ±5% accuracy.

Applications and users

EN 13541:2012 is used by:

• Glazing manufacturers and product developers to design and certify blast-resistant glazing.
• Independent testing laboratories performing shock-tube blast tests.
• Façade engineers, architects and security consultants specifying explosion pressure resistant glazing for critical infrastructure, government buildings, transportation hubs and high-risk sites.
• Building owners and authorities assessing glazing options for anti-terrorism, public safety and protective construction projects.
