Railway applications - Braking - Brake blocks

This European Standard gives the requirements for the design, dimensions, performance, and testing of a brake block (otherwise known as brake shoe insert) that acts on the wheel tread as part of a tread brake system. This European Standard does not cover cast iron brake block requirements.
This European Standard is applicable to brake blocks of either "K", "L", or "LL" friction level designed to be fitted to tread braked rail vehicles.
This European Standard contains the requirements for interfacing the brake block with the rail vehicle, the testing procedures in order to confirm that it satisfies the basic safety and technical interchangeability requirements, the material control procedures to ensure product quality, reliability and conformity and considers health and environmental needs.

Bahnanwendungen - Bremse - Bremsklötze

Diese Europäische Norm enthält Anforderungen an Auslegung, Abmessungen, Leistung und Prüfung eines Bremsklotzes (auch bekannt als „Bremsklotzsohle“), die auf die Lauffläche als Teil eines Klotzbremssystems wirkt. Diese Norm behandelt keine Anforderungen an Bremsklötze aus Gusseisen.
Diese Europäische Norm ist für Bremsklötze der Reibungsklassen „K“, „L“, oder „LL“ anwendbar, die für den Einbau in Schienenfahrzeuge mit Klotzbremse ausgelegt sind.
Diese Norm enthält die Anforderungen für die Schnittstelle zwischen Bremsklotz und Schienenfahrzeug, die Prüfverfahren zur Bestätigung, dass die grundlegenden Sicherheitsanforderungen und technischen Anfor¬derungen der Austauschbarkeit erfüllt werden, Kontrollverfahren für Werkstoffe zur Sicherstellung der Pro¬duktqualität, Funktionssicherheit und Konformität und berücksichtigt gesundheits- und umweltrelevante Bedürfnisse.

Applications ferroviaires - Freinage - Semelles de frein

La présente Norme européenne spécifie les exigences relatives à la conception, aux dimensions, aux performances et aux essais d’une semelle de frein (également appelée « semelle de freinage ») qui agit sur la table de roulement de la roue dans le cadre d’un système de frein sur roue. La présente Norme européenne ne traite pas des exigences relatives aux semelles de frein en fonte.
La présente Norme européenne s’applique aux semelles de frein à coefficient de frottement de niveau « K », « L » ou « LL » conçues pour être montées sur des véhicules ferroviaires à freins sur roue.
La présente Norme européenne spécifie les exigences relatives à l’interface de la semelle de frein avec le véhicule ferroviaire, les modes opératoires d’essai pour confirmer la satisfaction des exigences de base en matière de sécurité et d’interchangeabilité technique, les modes opératoires de contrôle des matériaux pour s’assurer de la qualité, de la fiabilité et de la conformité des produits, et tient compte des besoins en matière de santé et d'environnement.

Železniške naprave - Zavore - Zavorne ploščice

Ta evropski standard podaja zahteve za zasnovo, mere, zmogljivost in preskušanje zavornih ploščic (imenovanih tudi vložek zavorne čeljusti), ki deluje na tekalni profil kot del zavornega sistema s tekalnim profilom. Ta evropski standard ne zajema zahtev za zavorne ploščice iz litega železa.
Ta evropski standard se uporablja za zavorne ploščice s stopnjo trenja »K«, »L« ali »LL«, ki so zasnovane za namestitev na železniška vozila z zavornim sistemom s tekalnim profilom.
Ta evropski standard vsebuje zahteve za stik zavorne ploščice z železniškim vozilom, preskusne postopke za potrditev izpolnjevanja osnovnih zahtev glede varnosti in tehnične zamenljivosti, postopke nadzora materiala za zagotavljanje kakovosti, zanesljivosti in skladnosti izdelkov ter upošteva zdravstvene in okoljske zahteve.
