Gas welding equipment - Air-aspirated hand blowpipes - Specifications and tests (ISO 9012:2008)
ISO 9012:2008 specifies requirements and test methods for air-aspirated hand blowpipes.
ISO 9012:2008 applies to blowpipes for brazing, soldering, heating, fusion and other allied thermal processes, which use a fuel gas and aspirated air (injector-type blowpipes), and are intended for manual use.
ISO 9012:2008 is applicable to: air-aspirated hand blowpipes which are fed with a fuel gas in the gaseous phase, at a controlled pressure by a regulator, through a gas supply hose; air-aspirated hand blowpipes which are fed with a liquefied fuel gas in the gaseous phase at the container pressure, through a gas supply hose; so-called liquid-phase blowpipes which are fed with a fuel gas in the liquid phase, and where thermal evaporation takes place within the blowpipe.
Gasschweißgeräte - Handbrenner für angesaugte Luft - Anforderungen und Prüfungen (ISO 9012:2008)
Diese Internationale Norm legt Anforderungen und Prüfverfahren für Handbrenner für angesaugte Luft fest.
Diese Internationale Norm gilt für Brenner zum Hartlöten, Weichlöten, Wärmen, Schmelzen und für ähnliche thermische Verfahren, die mit Brenngas und angesaugter Luft betrieben worden (Düsenbrenner) und dazu eingerichtet sind, von Hand geführt zu werden.
Diese Internationale Norm gilt für:
- Handbrenner für angesaugte Luft, denen das Brenngas durch einen Brenngasschlauch mit einem bestimmten, durch Regler einstellbaren Druck in gasförmigem Zustand zugeleitet wird;
- Handbrenner für angesaugte Luft, denen Flüssiggas durch einen Brenngasschlauch mit dem im Behälter herrschenden Druck in gasförmigem Zustand zugeleitet wird;
- sogenannte Flüssiggasverdampfungsbrenner, denen Flüssiggas in flüssigem Zustand zugeleitet wird und bei denen thermisches Verdampfen innerhalb des Brenners erfolgt.
Sie gilt nicht für Brenner, bei denen das Brenngas in flüssiger Phase an der Düse austritt. Sie gilt ebenfalls nicht für sogenannte Kartuschenbrenner, bei denen der Brenngasbehälter (die Kartusche) unmittelbar mit dem Brenner verbunden ist und gegebenenfalls als Griffstück dient.
ANMERKUNG Bild 1 bis Bild 4 in dieser Internationalen Norm dienen lediglich der Erläuterung und einem besseren Verständnis der Begriffserklärungen. Es werden keine Einzelheiten der Konstruktion vorgeschrieben, diese bleiben dem Hersteller überlassen.
Équipement de soudage aux gaz - Chalumeaux manuels aéro-gaz à air aspiré - Spécifications et essais (ISO 9012:2008)
L'ISO 9012:2008 spécifie les exigences et les méthodes d'essai des chalumeaux manuels aéro-gaz à air aspiré.
L'ISO 9012:2008 s'applique aux chalumeaux destinés au brasage fort, au brasage tendre, au chauffage, à la fusion et aux autres procédés thermiques similaires, utilisant un gaz combustible et de l'air aspiré (chalumeau à air induit), conçus pour une utilisation manuelle.
L'ISO 9012:2008 s'applique également aux chalumeaux manuels aéro-gaz à air aspiré, alimentés par un gaz combustible en phase gazeuse, sous une pression régulée par un détendeur, à travers un tuyau d'amenée de gaz, aux chalumeaux manuels aéro-gaz à air aspiré, alimentés par un gaz combustible liquéfié en phase gazeuse sous la pression du réservoir, à travers un tuyau d'amenée de gaz et aux chalumeaux dits à phase liquide, alimentés par un gaz combustible en phase liquide et dans lesquels se produit une évaporation thermique.
Oprema za plamensko varjenje - Ročni gorilniki z vsesavanjem zraka - Popisi in preskusi (ISO 9012:2008)
ISO 9012:2008 določa zahteve za preskusne metode za ročne gorilnike z vsesavanjem zraka.
ISO 9012:2008 velja za gorilnike za trdo spajkanje, spajkanje, ogrevanje, spajanje in druge sorodne termične procese, ki uporabljajo kurilni plin in vsesani zrak (gorilniki injektorskega tipa) in so namenjeni ročni uporabi.
ISO 9012:2008 velja za: ročne gorilnike z vsesavanjem zraka, ki se napajajo s kurilnim plinom v plinski fazi pri tlaku, nadzorovanem z regulatorjem, prek cevi za plinsko oskrbo; ročne gorilnike z vsesavanjem zraka, ki se napajajo z utekočinjenim kurilnim plinom v plinski fazi pri tlaku vsebnika prek cevi za plinsko oskrbo; t. i. gorilnike na tekočo fazo, ki se napajajo s kurilnim plinom v tekoči fazi in pri katerih znotraj gorilnika poteka termično izparevanje.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 9012 was prepared by Technical Committee ISO/TC 44, Welding and allied processes, Subcommittee
SC 8, Equipment for gas welding, cutting and allied processes.
This third edition cancels and replaces the second edition (ISO 9012:1998), which has been technically
revised.
Requests for official interpretations of any aspect of this International Standard should be directed to the
Secretariat of ISO/TC 44/SC 8 via your national standards body. A complete listing of these bodies can be
found at www.iso.org.
