Tannery machines - Rotating process vessels - Safety requirements
This European Standard specifies safety requirements for design, construction, operation, adjustment, setting, cleaning and maintenance of a machine. This standard covers the following machines (see annex C and Figures 1 and 2 for typical configurations): a) horizontal rotating vessels; b) inclined rotating vessels. This standard does not apply to machines using substances containing solvent, that would generate fume and/or vapour detrimental to health, or that may lead to fire or explosive atmosphere. This standard takes account of intended use, foreseeable misuse, component and systems failure. The machines are for fixed installation. This document is not applicable to the rotating vessels which are manufactured before the date of its publication as EN." This standard does not establish any requirements for electromagnetic disturbances.

1.4 Diese Norm befasst sich mit der bestimmungsgemäßen Verwendung, vorhersehbarem Missbrauch und möglichem Versagen der Bauteile und des Systems.
Diese Maschinen sind Festinstallationen.
1.5 !Dieses Dokument gilt nicht für rotierende Gefäße, die vor dem Datum seiner Veröffentlichung als Europäische Norm gebaut werden."
1.6 Diese Norm legt keine Anforderungen für elektromagnetische Verträglichkeit fest.
ANMERKUNG Die Richtlinie 94/9/EG zu Ausstattung und Sicherheitssystemen in potentiell explosionsfähiger Atmosphäre kann für die in dieser Europäischen Norm behandelten Arten von Maschinen oder Ausrüstung Anwendung finden. Die derzeitige Norm entspricht jedoch nicht in allem der Richtlinie 94/9/EG. In eine zukünftige Überarbeitung müssen zur Erfüllung der Richtlinie 94/9/EG möglicherweise zusätzliche Sicherheitsanforderungen aufgenommen werden.

Strojarski stroji - Vrteče se procesne posode - Varnostne zahteve
Ta evropski standard opredeljuje varnostne zahteve za načrtovanje, gradnjo, obratovanje, prilagoditev, nastavitev, čiščenje in vzdrževanje stroja. Ta standard vključuje naslednje stroje (glej Prilogo C in Sliki 1 in 2 za značilne konfiguracije): a) horizontalne vrteče se posode; b) vrteče se posode z naklonom. Ta standard ne velja za stroje, ki uporabljajo snovi z vsebovanim topilom, katero bi povzročalo nastanek zdravju škodljivih plinov in/ali hlapov, ali ki bi lahko vodilo k nastanku požara ali eksplozivne atmosfere. Ta standard obravnava predvideno uporabo, predvidljivo napačno uporabo ter okvaro komponent in sistemov. Stroji so namenjeni fiksni namestitvi. Ta dokument se ne nanaša na vrteče se posode, ki so proizvedene pred datumom, ko je dokument objavljen kot EN. Ta standard ne vzpostavlja nikakršnih zahtev za elektromagnetne motnje.

For hazards which are to be reduced by the application of a type B-standard such as EN 294, EN 953,
EN ISO 13850, EN 60204-1 etc., the manufacturer shall carry out a risk assessment to establish the requirements of the B-standards which are to be applied." SIST EN 13114:2003+A1:2010

On release of the force no detectable distortion of the guard shall remain. 5.2.1.4 !Where the above measures cannot be applied the following protective devices shall be provided which will shutdown the hazardous motion before the danger point is reached." !Suitable protective devices are: movable interlocking guards which satisfy EN 953, EN 1088, 5.3.2.3 of EN ISO 12100-2:2003 and the distances given in the appropriate table (1 or 3) of EN 294:1992,; trip devices, such as: electrosensitive protective devices satisfying EN 61496-1, CLC/TS 61496-2 and EN 999; pressure sensitive protective device satisfying EN 1760-2 type 3.1 or 3.2." 5.2.2 High pressure fluid and burst component part ejection If a machine is fitted with hydraulic/pneumatic equipment a loss of fluid under high pressure may arise and result in a hazard of impact either directly or by impelled objects. For liming and vegetable retanning drums it is necessary to provide the machine with a device to vent the inside of the rotating body. For maintenance of the venting device !see 7.3.5 d)" of this standard. The risk of injury caused by escaping spurts/jets of fluid or impelled objects shall be reduced to the lowest practical level by the provision of fixed enclosing guards or solid screens.
