4、This Technical Report was drawn up by the Non-metallic Material Domain of AECMA-STAN. The reason which led to the publication of the document as a Technical Report is explained in the foreword. Page 2 TR 7000-2: 06-02 Foreword The main task of AECMA-STAN is to prepare EN standards. In exceptional ci
5、rcumstances, however, the publication of a Technical Report of one of the following types may be proposed : - type 1, the subject is still under technical development requiring wider exposure ; - type 2, a Technical Committee has collected data of a different kind from that which is normally publish
6、ed 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.
