Gas welding equipment - Air-aspirated hand blowpipes - Specifications and tests (ISO 9012:2023)
This document specifies requirements and test methods for air-aspirated hand blowpipes.
This document 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.
This document 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.
It does not apply to blowpipes in which the fuel gas leaves the injector in the liquid phase, or to so-called
“cartridge” blowpipes where the gas supply is fixed directly onto the blowpipe and possibly constitutes
the shank.
NOTE Figures 1 to 4 are given for guidance only, to facilitate the explanation of the terms. They do not
specify the construction details, which are left to the discretion of the manufacturer.
Gasschweißgeräte - Handbrenner für angesaugte Luft - Anforderungen und Prüfungen (ISO 9012:2023)
Dieses Dokument legt Anforderungen und Prüfverfahren für Handbrenner für angesaugte Luft fest.
Dieses Dokument ist anwendbar für Brenner zum Hartlöten, Weichlöten, Wärmen, Schmelzen und für ähnliche thermische Verfahren, die mit Brenngas und angesaugter Luft betrieben werden (Düsenbrenner) und dazu eingerichtet sind, von Hand geführt zu werden.
Dieses Dokument ist anwendbar 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.
Dieses Dokument ist nicht anwendbar für Brenner, bei denen das Brenngas in flüssigem Zustand an der Düse austritt. Es ist ebenfalls nicht anwendbar 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 dienen lediglich der Erläuterung und einem besseren Verständnis der Begriffserklärungen. Es werden keine Einzelheiten der Konstruktion vorgeschrieben, diese bleiben dem Hersteller überlassen.

Oprema za plamensko varjenje - Ročni gorilniki z vsesavanjem zraka - Popisi in preskusi (ISO 9012:2023)
Ta dokument določa zahteve in preskusne metode za ročne gorilnike z vsesavanjem zraka. Ta dokument se uporablja za gorilnike za postopke vsesavanja, spajkanja, segrevanja, spajanja in druge podobne toplotne procese, ki uporabljajo plinasto gorivo ali zrak za vsesavanje (gorilnik z vsesavanjem zraka s šobami) in so namenjeni ročni
uporabi.
Ta dokument se uporablja za:
– ročne gorilnike z vsesavanjem zraka, ki se polnijo s plinastim gorivom v plinski fazi pri tlaku, ki ga regulira regulator, prek dovodne cevi za plin;
– ročne gorilnike z vsesavanjem zraka, ki se polnijo z utekočinjenim plinastim gorivom v plinski fazi pri tlaku posode prek dovodne cevi za plin;
– tako imenovane gorilnike z vsesavanjem v utekočinjeni fazi, ki se polnijo s plinastim gorivom v tekoči fazi in kjer v gorilniku poteka
toplotno izhlapevanje.
Ta dokument se ne uporablja za gorilnike, kjer plinasto gorivo zapušča šobo v tekoči fazi, oziroma tako imenovane
gorilnike s »kartušo«, kjer je dovod plina neposredno usmerjen v gorilnik in lahko ustvarja
krak.

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.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO document should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use
of (a) patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed
patent rights in respect thereof. As of the date of publication of
