    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.

See examples in EN 7000-2 onwards. 4.5.3 Tables 2 to 4 This form shall be filled in accordance with the relevant part of this standard (see EN 7000-2 on

    47、wards). If all the characteristics covered by that particular table are not required, keep the table heading and write: - I NO requirements I If the characteristics covered by table 2 are the same as table 3 (.e. delivery condition is final condition of use) then keep the table 2 heading and write:

    48、- I No requirements: see table 3. I NOTE: Test requirements shown in the technical specification are only mandatory when referenced in the material standards.
