Gas cylinders - Refillable seamless steel gas cylinders and tubes - Acoustic emission examination (AT) and follow-up ultrasonic examination (UT) for periodic inspection and testing (ISO 16148:2016)
ISO 16148:2016 gives procedures for the use of acoustic emission examination (AT) and ultrasonic examination (UT) follow-up during the periodic inspection and testing of seamless steel cylinders and tubes with a water capacity of up to 3 000 l used for compressed and liquefied gases. This examination provides acoustic emission (AE) indications and locations that are evaluated by a secondary examination using UT for a possible flaw in the cylinder or tube. Methods other than UT for the secondary examination are not covered by this International Standard.
ISO 16148:2016 does not cover composite cylinders.
CAUTION ? Some of the tests specified in this International Standard involve the use of processes which could lead to a hazardous situation.
Gasflaschen - Wiederbefüllbare nahtlose Gasflaschen und Großflaschen aus Stahl - Schallemissionsprüfung und nachfolgende Ultraschallprüfung für die wiederkehrende Inspektion und Prüfung (ISO 16148:2016)
Diese Internationale Norm gibt Verfahren für die Anwendung der Schallemissionsprüfung (AT) und der nachfolgenden Ultraschallprüfung (UT) während der wiederkehrenden Inspektion und Prüfung von nahtlosen Flaschen und Großflaschen aus Stahl mit einem Fassungsraum bis zu 3 000 l für verdichtete und verflüssigte Gase an. Diese Prüfung ergibt AE-Befunde (AE) und -Ortungen, die durch eine weitere auf Ultraschallprüfung basierende Untersuchung auf eine mögliche Kerbe in der Flasche oder Großflasche bewertet werden. Neben der Ultraschallprüfung könnten andere Verfahren als weitere Prüfung angewendet werden, welche jedoch nicht in den Anwendungsbereich dieser Internationalen Norm fallen.
Diese Internationale Norm gilt nicht für Verbundflaschen.
VORSICHT — Einige der in dieser Norm beschriebenen Prüfungen beinhalten die Anwendung von Verfahren, die zu einer Gefährdungssituation führen können.
Bouteilles à gaz - Bouteilles à gaz rechargeables en acier sans soudure et tubes - Essais d'émission acoustique et examen ultrasonique complémentaire pour l'inspection périodique et l'essai (ISO 16148:2016)
ISO 16148:2016 décrit des modes opératoires de l'essai d'émission acoustique (EA) suivi du contrôle par ultrasons (UT) lors du contrôle et des essais périodiques des bouteilles et tubes en acier sans soudure, d'une capacité en eau allant jusqu'à 3 000 l, utilisés pour les gaz comprimés et liquéfiés. Cet examen par émission acoustique (EA) fournit des indications et des localisations qui sont évaluées par un deuxième examen utilisant les ultrasons (UT) pour déterminer un éventuel défaut dans la bouteille ou le tube. Pour ce deuxième examen, les méthodes autres que le contrôle UT ne sont pas couvertes par l'ISO 16148:2015.
ISO 16148:2016 ne couvre pas les bouteilles composites.
Plinske jeklenke - Ponovno polnljive plinske jeklenke in velike jeklenke iz celega - Preskus z akustično emisijo in ultrazvočni preskus pri periodičnem pregledu in preskušanju (ISO 16148:2016)
Ta mednarodni standard določa postopke za uporabo preskusa z akustično emisijo (AT) in ultrazvočnega preskusa (UT) med rednim pregledom in preskušanjem jeklenk in velikih jeklenk iz celega jekla z vodno prostornino do 3000 l za stisnjene in utekočinjene pline.
S tem preskusom se zagotovijo vrednosti in lokacije akustičnih emisij, ki so ovrednotene s
sekundarnim ultrazvočnim preskusom za ugotavljanje morebitne napake v jeklenki ali veliki jeklenki. Druge metode sekundarnega preskusa v tem mednarodnem standardu niso zajete.
Ta mednarodni standard ne zajema kompozitnih jeklenk.
POZOR – Nekateri preskusi, podani v tem mednarodnem standardu, vključujejo uporabo postopkov, ki lahko vodijo v nevarno stanje.

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 documents 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).
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. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation on the meaning of ISO specific terms and expressions related to conformity
assessment, as well as information about ISO’s adherence to the WTO principles in the Technical
Barriers to Trade (TBT) see the following URL: Foreword - Supplementary information
The committee responsible for this document is ISO/TC 58, Gas cylinders, Subcommittee SC 4,
Operational requirements for gas cylinders.
This second edition cancels and replaces the first edition (ISO 16148:2006), which has been technically
revised. The changes include
a) expansion of the scope to include tubes of water capacity up to 3 000 l used for compressed and
liquefied gases, and
b) addition of procedures for ultrasonic examination (UT) follow-up during periodic inspection, as
described in the new Annex A.
