11、l, which may be a semi- finished product, such 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 condi
12、tions. NOTE: A material standard may also specify 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
13、 this standard Previous page is blank 3.2 Family of non-metallic 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 polym
14、erizable compounds; - honeycombs; - paints; - reinforcement fibre; - preimpregnates; - textiles. 3.3 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: - adhes
15、ives where one delivered condition may be a two-part mix and the 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. 3.4 Type of semi-finished products Semi-finished p
16、roduct forms (sheets, rolls, tube, cloths, liquids, paste etc.) associated with the relevant family of non-metallic materials. 3.5 Final condition of use The condition of the material in which no further processing (except machining or shaping) is required before use. 3.6 Abbreviations Abbreviations
17、 shall be taken from IS0 31. The following are typical abbreviations used: - “a“ for thickness; - “b“ for width; - “I“ for length; - “Dl for outside diameter; - “d“ for inside diameter; - “0 for temperature; - “Y for time. NOTE 1: The abbreviation “min.“, for minimum shall not be used. When it is ne
18、cessary to state a minimum or maximum value this shall be done using the symbols I, , alternatively the word shall be written in full. The exception to this in when “min.“ and “max.“ are defined for other uses within abbreviations, e.g. Rmax. or Rmin NOTE 2: Values shall be preceded by a sign depend
19、ing on whether they are minimum or maximum values, (I, ); Symbols for sizes and units: see IS0 31-1, IS0 31-3, IS0 31-4, IS0 31-11 and IS0 1000.

20、 frame, are listed below for the different clauses of the material standard and are mandatory. When necessary, information in the frame, indicated in italics, shall be completed or reworded. 4.1 Page 1: Title of the material standard The title shall give sufficient information to unambiguously ident
21、ify the finished or semi-finished product, in the delivery condition or use condition where applicable. Consequently: 1 The same title shall not be used for different material standards 2 Overlapping of material physical or mechanical characteristics for otherwise identical material standards shall
22、not normally be permitted. Each part of the title shall form one or several different lines: - Aerospace series; - 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 and/or final
23、use; - dimensions if appropriate; - relevant mechanical or physical limits if appropriate. 4.2 Page 2 Blank in principle: foreword or contents list if necessary. 4.3 Page 3, onwards 4.3.1 Clause O: Introduction When required this clause shall read: O Introduction This standard is a level 3 document
