(Main)Pipe threads where pressure-tight joints are not made on the threads - Part 1: Dimensions, tolerances and designation (ISO 228-1:2000)
Pipe threads where pressure-tight joints are not made on the threads - Part 1: Dimensions, tolerances and designation (ISO 228-1:2000)
This part of ISO 228 specifies the requirements for thread form, dimensions, tolerances and designation for
fastening pipe threads, thread sizes 1/16 to 6 inclusive. Both internal and external threads are parallel threads,
intended for the mechanical assembly of the component parts of fittings, cocks and valves, accessories, etc.
These threads are not suitable as jointing threads where a pressure-tight joint is made on the thread. If assemblies
with such threads must be made pressure-tight, this should be effected by compressing two tightening surfaces
outside the threads, and by interposing an appropriate seal.
NOTE 1 For pipe threads where pressure-tight joints are made on the threads, see ISO 7-1.
NOTE 2 ISO 228-2 gives details of methods for verification of fastening thread dimensions and form, and recommended
gauging systems.
Rohrgewinde für nicht im Gewinde dichtende Verbindungen - Teil 1: Maße, Toleranzen und Bezeichnung (ISO 228-1:2000)
Dieser Teil der ISO 228 legt die Anforderungen an die Gewindeform, Masse, Toleranzen und Bezeichnung von Rohrgewindeverbindungen der Gewindegrössen 1/16 bis einschliesslich 6 fest. Beide, Innen- und Aussengewinde, sind zylindrische Gewinde und dienen zur mechanischen Verbindung der Teile von Fittings, Hähnen und Ventilen, Zubehör usw.
Filetages de tuyauterie pour raccordement sans étanchéité dans le filet - Partie 1: Dimensions, tolérances et désignation (ISO 228-1:2000)
La présente partie de l'ISO 228 spécifie les exigences relatives à la forme, aux dimensions, aux tolérances et à la
désignation des filetages de tuyauterie pour raccordement, de dimensions de filetage 1/16 à 6 comprises. Les
filetages intérieurs comme les filetages extérieurs sont des filetages cylindriques qui s'appliquent aux assemblages
mécaniques des pièces de raccords, de robinetterie, d'accessoires, etc.
Ces filetages ne conviennent pas comme filetages avec étanchéité dans le filet. Si des assemblages les utilisant
doivent être rendus étanches, cela se fera par le serrage de deux surfaces d'étanchéité en dehors du filetage, et
en interposant un joint d'étanchéité approprié.
NOTE 1 Pour les filetages de tuyauterie pour raccordement avec étanchéité dans le filet, voir ISO 7-1.
NOTE 2 L'ISO 228-2 donne des précisions sur les méthodes de vérification des dimensions et de la forme des filetages de
raccordement, et sur les systèmes de calibrage recommandés.

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 3.
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 part of ISO 228 may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
International Standard ISO 228-1 was prepared by Technical Committee ISO/TC 5, Ferrous metal pipes and
metallic fittings, Subcommittee SC 5, Threaded or plain end butt-welding fittings, threads, gauging of threads.
This fourth edition cancels and replaces the third edition (ISO 228-1:1994), which has been technically revised.
ISO 228 consists of the following parts, under the general title Pipe threads where pressure-tight joints are not
made on the threads:
— Part 1: Dimensions, tolerances and designation
— Part 2: Verification by means of limit gauges
Annex A of this part of ISO 228 is for information only.

Dimensions, tolerances and designation
1 Scope
This part of ISO 228 specifies the requirements for thread form, dimensions, tolerances and designation for
fastening pipe threads, thread sizes 1/16 to 6 inclusive. Both internal and external threads are parallel threads,
intended for the mechanical assembly of the component parts of fittings, cocks and valves, accessories, etc.
These threads are not suitable as jointing threads where a pressure-tight joint is made on the thread. If assemblies
with such threads must be made pressure-tight, this should be effected by compressing two tightening surfaces
outside the threads, and by interposing an appropriate seal.
NOTE 1 For pipe threads where pressure-tight joints are made on the threads, see ISO 7-1.
NOTE 2 ISO 228-2 gives details of methods for verification of fastening thread dimensions and form, and recommended
gauging systems.
