The reason which led to the publication of the document as a Technical Report is explained in the foreword. Page 2 TR 7000-9: 06-02 Foreword

5、The main task of AECMA-STAN is to prepare EN standards. In exceptional circumstances, however, the publication of a Technical Report of one of the following types may be proposed : - type I, the subject is still under technical development requiring wider exposure ; - type 2, a Technical Committee h

6、as collected data of a different kind from that which is normally published as a European Standard. The Non-metallic Material Domain decided to publish this document in the form of a Technical Report of type 2 in order to facilitate the updating of this document.
