Automatic steam traps - Production and performance characteristic tests (ISO 5117:2023)
This document specifies the production and performance relevant test requirements for automatic steam traps used for condensate removal/recovery services for optimized utilization of energy, in refinery, power generation or other general applications where steam is used as a medium of heat transfer.
The tests can be classified as production tests and performance characteristic tests and can be conducted to ensure the correct functioning of a steam trap or to evaluate the performance of a particular design. This document specifies the tests performed relative to each one of these two categories and briefly describes the corresponding test methods.
Kondensatableiter - Fertigungsprüfung und Prüfung der Funktionsmerkmale (ISO 5117:2023)
Dieses Dokument legt die Anforderungen an die fertigungsbegleitende und leistungsfähigkeitsbezogene Prüfung von Kondensatableitern fest, die zur Kondensatableitung/ rückgewinnung für eine optimierte Energieausnutzung in Raffinerien, bei der Stromerzeugung oder anderen allgemeinen Anwendungen eingesetzt werden, bei denen Dampf als Medium zur Wärmeübertragung verwendet wird.
Die Prüfungen lassen sich in fertigungsbegleitende Prüfungen und Prüfungen von Funktionsmerkmalen einteilen und können durchgeführt werden, um die korrekte Funktion eines Kondensatableiters sicherzustellen oder um die Leistung einer bestimmten Ausführung zu bewerten. Dieses Dokument legt die Prüfungen fest, die in Bezug auf jede dieser beiden Kategorien durchgeführt werden, und beschreibt die entsprechenden Prüfverfahren in Kürze.
Purgeurs automatiques de vapeur d'eau - Essais de production et essais des caractéristiques de fonctionnement (ISO 5117:2023)
Le présent document spécifie les exigences d’essai de production et d'essai des caractéristiques de fonctionnement applicables pour les purgeurs automatiques de vapeur d’eau utilisés pour des services d’évacuation/de récupération de condensat pour une utilisation optimisée de l’énergie, dans les raffineries, les centrales électriques ou d’autres applications générales où la vapeur d’eau est utilisée comme un moyen de transfert de chaleur.
Les essais peuvent être classés comme des essais de production et des essais de caractéristiques de performance et peuvent être conduits afin de s’assurer du fonctionnement correct d’un purgeur de vapeur d’eau ou pour évaluer les performances d’une conception particulière. Le présent document spécifie les essais à effectuer pour chacune de ces deux catégories et décrit brièvement les méthodes d’essai correspondantes.
Avtomatični izločevalniki kondenzata - Tehnološko in funkcijsko preskušanje (ISO 5117:2023)
Ta dokument določa zahteve, pomembne za proizvodnjo in lastnosti avtomatičnih izločevalnikov kondenzata, ki se uporabljajo za odstranjevanje/rekuperacijo kondenzata za optimalno uporabo energije v rafinerijah, pri proizvodnji električne energije ali drugih vrstah splošne uporabe, pri katerih se para uporablja kot medij za prenos toplote.
Preskuse je mogoče razvrstiti med tehnološke in funkcijske preskuse, izvede pa se jih lahko za zagotovitev pravilnega delovanja izločevalnika kondenzata ali ocenjevanje delovanja določene zasnove. Ta dokument določa preskuse za vsako od teh dveh kategorij in vsebuje kratek opis ustreznih preskusnih metod.

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.

Introduction
Testing of steam traps provides conformance of product performance to the intended function. This
document addresses the requirements for production testing and performance testing of steam traps.
Production test ensures the shell integrity to the maximum working pressure while the performance
test ensures the functional requirement of steam traps. Performance test should be considered as type
test.
Testing is the most reliable method to validate a product including design, material selection and
manufacturing processes. It may also serve as a guide for
