30、am or one continuously woven length not exceeding 20 000 metres, provided that weft yarn of consistent and proven quality has been used NOTE If a fresh delivery of weft yarn of unproven quality is introduced during weaving the warp, a fresh batch has been created. 1) Published as AECMA Prestandard a
31、t the date of publication of this standard. 2) Published as AECMA Technical Report at the date of publication of this standard. EN 4415:20066 3.1.2 piece treated fabric Finishers Batch is that which comprises one or more loomstate Production Batches, possibly comprising more than one type of fabric,
32、 subject to piece treatment under the same conditions, within the same operation An Inspection Batch is the quantity of fabric of the same type, from one loomstate Production Batch. NOTE If several loomstate Production Batches are brought together during the finishing process to form one large Finis
33、hers Batch, due note should be taken of the need to maintain identification of each individual batch. 3.2 defect fault that would reduce the expected performance of the fabric or, if it appeared in a prominent position in an article made from the fabric, would readily be seen and rejected by a prosp
34、ective purchaser For definitions of specific defects refer to ISO 8498. 3.3 fabric manufactured assembly of fibres and/or yarns that has substantial surface area in relation to its thickness and sufficient mechanical strength to give the assembly inherent cohesion 3.4 manufacturer firm making the ma
35、terial into the form (yarn, loomstate fabric, finished fabric, etc.) in which it is consigned to the purchaser 3.5 narrow woven fabric fabric woven at 450 mm width or less between selvedges and not obtained by slitting wide fabric 3.6 product in this document the word product refers to all forms of
36、narrow woven fabric 3.7 purchaser body which purchases the product from a manufacturer or a stockist in accordance with the requirements of the user NOTE The purchaser may also be the user. 3.8 supplier firm consigning the material to the purchaser NOTE The supplier may be either the manufacturer or
37、 the stockist. 3.9 textile any fabric (however constructed), sewing thread or cordage made from natural or man made fibres and/or yarns, and blends of these EN 4415:20067 4 Requirements 4.1 General requirements 4.1.1 Manufacturing schedule The product shall be manufactured to fulfil the requirements
38、 of the relevant material standard and this technical specification. The manufacturer shall define the raw material, processes and inspection requirements in a manufacturing schedule. 4.1.2 Traceability All products shall be traceable to the raw material batches at all stages of manufacture and deli
39、very. Similarly, each raw material batch shall be traceable to all products at all stages of manufacture and delivery. 4.1.3 Freedom from defects All products shall be free from defects not complying with the requirements of the material standard or order and this technical specification, or which m
40、ay be prejudicial to the subsequent manufacture and/or use of the products. The requirements for freedom from defects are given in Annex B of this specification. 4.1.4 Health and safety It is the responsibility of the supplier to establish satisfactory health and safety information to ensure conform
41、ity with any European, National or local laws/regulations. 4.1.5 Dimensions 4.1.5.1 General Dimensions and tolerances shall conform to the requirements of the order or drawing and unless otherwise specified in the individual material standard, with subclauses 4.1.5.2 to 4.1.5.4. NOTE If loomstate fa
42、bric is subsequently to be processed, e.g. scoured, dyed or coated, allowance should be made for the consequent shrinkage. 4.1.5.2 Width When measured in accordance with the test method listed in Annex A, the width of the fabric shall be as specified in the individual material standard, with the tol
43、erances given in Table 1. Table 1 Nominal width mm Tolerance mm Less than 12 12 to less than 55 55 and over 1,0 1,5 4 % aa Rounded up to nearest 1,0 mm EN 4415:20068 4.1.5.3 Length The length of each roll of the product shall be: not less than 100 m for fabric weighing 50 g/m or less; not less than
44、50 m for fabric weighing more than 50 g/m NOTE Length measurement by means of a roller counter has been found suitable. In each roll there shall be not more than four cuts per 100 m which shall not be joined by pins, metal fasteners or other means. No individual part shall be less than 10 m long. Th
45、e total number of cuts in a consignment shall not exceed four times the number of rolls for fabrics of 50 g/m or less, or twice the number of rolls for fabrics exceeding 50 g/m. 4.1.5.4 Warp bow When measured in accordance with the test method listed in Annex A, the warp bow shall not exceed 10 mm/m
46、 length. 4.1.6 Manufacture 4.1.6.1 The narrow woven fabric shall be uniformly manufactured. 4.1.6.2 The edges shall be straight and even. 4.1.6.3 If the edge structure is not specified in the material standard, the edges shall not be substantially thicker than the body of the fabric. NOTE Certain we
47、aving processes generate selvedges that may be slightly thicker than the body of the fabric. Any difference in thickness should be kept to a minimum so as not to hinder the subsequent manufacturing process. 4.1.6.4 The weaving process shall be as specified in the material standard and shall be one o
48、f the following approved for aerospace use: a) Conventional (i.e. woven on a shuttle loom); b) Shuttleless with the weft locked by a thread inserted from a “bobbin”, the locking thread engaging with the weft within the body of the webbing at not less than 8 warp ends from the selvedge; c) Shuttleles
49、s with the weft knitted at one selvedge with a locking thread; d) Shuttleless with the weft secured at one selvedge by two knitted locking threads. NOTE The suitability of a weaving process for a narrow woven fabric for a particular equipment application is the responsibility of the equipment design authority. 4.1.6.5 In fabric of multi-ply construction containing binder warp threads, the binders shall be uniformly spaced in t
