5、o an extent that interchangeability is affected, physically or functionally, without re-identification of the standard. After examination and review by users and formal agreement of ASD-STAN, the ASD-STAN prEN will be submitted as a draft European Standard (prEN) to CEN (European Committee for Stand
6、ardization) for formal vote and transformation to full European Standard (EN). The CEN national members have then to implement the EN at national level by giving the EN the status of a national standard and by withdrawing any national standards conflicting with the EN.

13、Ns General Process Manual, this standard has received approval for Publication. Introduction This standard is co-owned standard and a functional equivalent of AS5550. There should be no technical objection to use AS5550 as replacement of EN 4833 parts. Table 3 shows the equivalent cross reference of
14、 EN 4833 part numbers to AS5550 part numbers. 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 w
15、orking 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. Th
16、erefore, 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 with
17、in European Standards. prEN 4833:2017 (E) 4 1 Scope This standard specifies the dimensions, tolerances, required characteristics and the mass of an adaptor, flareless tube end EN 6123, ring locked type, for use in 35 000 kPa (5 080 psi) working pressure systems. 2 Normative references The following

48、this standard and qualification tests in accordance with the requirements of EN 9133 and EN 4832. The manufacturers operations shall be an approved production organisation for aerospace products and shall demonstrate that it has implemented and is able to maintain a quality system (e.g. according to
49、 EN 9100 or another in aerospace accepted and established quality management system). Unless otherwise specified, the supplier may use his own facilities or any commercial laboratory acceptable to the procuring activity. The purchaser reserves the right to perform any of the inspections set out in the procurement specification where such inspections are deemed necessary to ensure
