Foreword

This European Standard (EN 3155-022:2006) has been prepared by the AeroSpace and Defense Industries Association of Europe - Standardization (ASD-STAN)

After enquiries and votes carried out in accordance with the rules of this Association, this Standard has re-ceived 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of an identical text or by endorsement, at the latest by January 2007, and conflicting national standards shall be withdrawn at the latest by January 2007

Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights CEN [and/or CENELEC] 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, Cyprus, Czech Republic, Den-mark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxem-bourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzer-land and the United Kingdom

1 Scope

This standard specifies the required characteristics, tests and tooling applicable to rectangular male con-tacts 022, type A, crimp, class R, used in elements of connection according to EN 3155-002

It shall be used together with EN 3155-001

The associated female contacts are defined in EN 3155-023 They also mate with the female non-removable size 22 solder contacts of EN 3218-005 and EN 3218-006
