4、It is published for the needs of the European Aerospace Industry. It has been technically approved by the experts of the concerned Domain following member comments. Subsequent to the publication of this Prestandard, the technical content shall not be changed to an extent that interchangeability is a
5、ffected, 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 Standardization) for formal vote and transfor
6、mation 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. ASD-STAN Technical Committee approves that: “This document is publishe
7、d 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 use, including any patent infringement arising therefrom, is the sole responsibility of the user.” ASD-STAN reviews each standard a
8、nd technical report at least every five years at which time it may be revised, reaffirmed, stabilized or cancelled.

12、 4811:2015 (E) 3 1 Scope This standard specifies the characteristics of gasket seal with fluorocarbon seal on aluminium plate, 4 holes, for pipe couplings for inch series aerospace applications. Nominal pressure: Up to 21 000 kPa; depends on the associated tube material and tube wall thickness in th
13、e assembly (see EN 4814). Temperature range: 20 C to 200 C. NOTE Assembly in accordance with TR 4815. This part should not be resuse after disassembling. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its app
