European foreword
This document (EN 4834:2018) has been prepared by the Aerospace and Defence Industries
Association of Europe - Standardization (ASD-STAN).
After enquiries and votes carried out in accordance with the rules of this Association, this Standard has
received the approval of the National Associations and the Official Services of the member countries of
ASD, prior to its presentation to CEN.
This European Standard shall be given the status of a national standard, either by publication of an
identical text or by endorsement, at the latest by February 2019, and conflicting national standards
shall be withdrawn at the latest by February 2019.
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. CEN shall not be held responsible for identifying any or all such patent rights.
According to the CEN-CENELEC Internal Regulations, the national standards organizations of the
following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria,
Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia,
France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta,
Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden,
Switzerland, Turkey and the United Kingdom.
Introduction
This European Standard is co-owned standard and a functional equivalent of AS5551. There should be
no technical objection to use AS5551 as replacement of EN 4834 parts. Further revisions to this
standard shall be coordinated with the SAE committee.
European standards use the International System of units (SI); however, large segments of the
aerospace industry make use of other measurement systems as a matter of common working practice.
All dimensions and units used in this standard are given in SI units, with other units also indicated for
the convenience of the user.
The decimal sign used in European standards is the comma (“,”); however, the comma is not used in
common working practice with non-SI dimensions. Therefore, in common with many other aerospace
standards, the decimal point (“.”) is used in this standard when providing dimensions in inch-pound
units.
NOTE The use of non-SI units and the decimal point in this standard does not constitute general acceptance
of measurement systems other than SI within European standards.
1 Scope
This European Standard specifies the dimensions, tolerances and requirements of a port for a fluid
connection with ring locked fitting, for use in aircraft systems at nominal operating pressure of
35 000 kPa (5 080 psi) maximum and temperature range of −54 to +135 °C (−65 to +275 °F).
