5、sequent to the publication of this Prestandard, the technical content shall not be changed to 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 prE
6、N will be submitted as a draft European Standard (prEN) to CEN (European Committee for Standardization) 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 b
7、y withdrawing any national standards conflicting with the EN. ASD-STAN Technical Committee approves that: “This document is published by ASD-STAN for the needs of the European Aerospace Industry. The use of this standard is entirely voluntary and its applicability and suitability for any particular
8、use, including any patent infringement arising therefrom, is the sole responsibility of the user.” ASD-STAN reviews each standard and technical report at least every five years at which time it may be revised, reaffirmed, stabilized or cancelled.

After inquiries and
13、votes carried out in accordance with the rules of ASD-STAN defined in ASD-STANs General Process Manual, this standard has received approval for Publication. Introduction This standard is co-owned standard and a functional equivalent of AS5865. There should be no technical objection to use AS5865 as
14、replacement of EN 4836 parts. Table 3 shows the equivalent cross reference of EN 4836 part numbers to AS5865 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 aer
15、ospace 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
16、, 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 doe
17、s not constitute general acceptance of measurement systems other than SI within European Standards. prEN 4836:2017 (E) 4 1 Scope This standard specifies the dimensions, tolerances, required characteristics and the mass of a reducer, flareless tube end EN 6123, ring locked type, for use in 35 000 kPa
