Hydraulic fluid power - Test methods for couplings actuated with or without tools

ISO 18869:2017 specifies methods for testing and evaluating the performance of quick-action couplings for use in hydraulic fluid power applications. This document does not apply to the testing of tube connections, stud ends for ports and flange connections, which are covered by ISO 19879.Test methods covered in this document are independent of each other and outline the method to follow for each test. See the respective connector standard for which tests to conduct and for performance requirements. It is not intended that all tests be carried out for every application; it is up to the user of this document to select the applicable tests.For qualification of the coupling, the minimum number of samples specified in this document is to be tested, unless otherwise specified in the relevant coupling standard or as agreed upon by the manufacturer and the user.

Hydraulic fluid power - Quick-action couplings - Part 2 : test methods

La présente partie de l'ISO 7241 spécifie différentes méthodes d'essai auxquelles peuvent être soumis les raccords rapides. NOTE L'utilisateur de la présente partie de l'ISO 7241 peut choisir uniquement la méthode d'essai adaptée à ses besoins. Il n'est pas prévu de réaliser tous les essais pour chaque application. La présente partie de l'ISO 7241 est applicable aux demi-raccords mâle et femelle, aux raccords assemblés, aux raccords avec ou sans systèmes d'étanchéité à l'état désaccouplé, et aux raccords accouplés et désaccouplés par un mouvement linéaire, par un mouvement de rotation ou par un mouvement combinant les deux précédents.

ZOOM ON ... the Requirements department
To comply with a standard, you need to quickly understand its issues in order to determine its impact on your activity.

The Requirements department helps you quickly locate within the normative text:
- mandatory clauses to satisfy,
- non-essential but useful clauses to know, such as permissions and recommendations.

The identification of these types of clauses is based on the document “ISO / IEC Directives, Part 2 - Principles and rules of structure and drafting of ISO documents ”as well as on a constantly enriched list of verbal forms.
