In exceptiona

6、l circumstances, 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 pub

7、lished 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.

The general organisation of this se

10、ries is described in EN 4385. This document is a level 2 document as defined in EN 4385. 1 Scope This standard specifies the general rules for the drafting and presentation of non-metallic material standards, for aerospace applications. It is supported by additional rules specific to each family, de

11、fined in TR 7000-2 onwards. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the next and the publications are listed hereafter. For dated references, subseq

16、h as: - one or more delivery conditions, - one reference set of processing conditions for acceptance test and qualification purposes which may differ from the use condition intended by the user, - series of technical requirements for these different conditions NOTE A material standard may also speci

17、fy one or more than one use condition, providing that the variants are not interconvertable. Such cases shall be clearly identified by the designation system given in the material standard. 1) Published as AECMA Prestandard at the date of publication of this standard 2) Published as AECMA Technical

19、c material a group of non-metallic materials characterised by basic descriptions generally in semi-finished product forms such as but not exclusively: - rubbers, - sealants, - transparent plastics, - glass, - adhesives, - anaerobic polymerizable compounds, - honeycombs, - paints, - reinforcement fib

20、re, - preimpregnates, - textiles 3.1.3 semi-finished products a generic term used to indicate that the material as delivered is in an intermediate form to that occuring in the final component This term may refer to the following: - adhesives where one delivered condition may be a two-part mix and th

21、e final use condition is the cured adhesive; - preimpregnates, which are subsequently shaped to produce a part with specified characteristics; - honeycomb which may be shaped and formed. 3.1.4 type of semi-finished products semi-finished product forms (sheets, rolls, tube, cloths, liquids, paste etc

22、.) associated with the relevant family of non-metallic materials 3.1.5 final condition of use the condition of the material in which no further processing (except machining or shaping) is required before use 3.2 Symbols and abbreviations For the purpose of this standard, the following symbols and ab

23、breviations shall apply: Abbreviations shall be taken from IS0 31. The following for sizes and units shall be taken from IS0 31-1, IS0 31-3, IS0 31-4, IS0 31-11 and IS0 1000. The following are typical symbols used: - %”for thickness; - ”b”for width; - lfor length; - Dfor outside diameter; - “”for in

24、side diameter; - “afor temperature; - “f”for time; - “RH”for relative humidity. NOTE The abbreviation “min.”, for minimum shall not be used. When it is necessary to state a minimum or maximum value this shall be done using the symbols , , alternatively the word shall be written in full. The exceptio

25、n to this in when “min.” and ”max.” are defined for other uses within abbreviations, e.g. Rmax. or - The family of the non-metallic material; - Form or forms, written in singular or plural, in conformity with the language used and, if appropriate, the method of production andlor final use; - Dimensi

26、ons if appropriate; - Relevant mechanical or physical limits if appropriate. 4.2 Clause O: Introduction When required, this clause shall read: O Introduction This standard is part of the series of EN non-metallic materials standards for aerospace applications. The general organisation of this series

27、 is described in EN 4385. This standard is a level 3 document as defined in EN 4385.
