In addition the following definitions are appl
24、icable. 3.1.1 Batch 3.1 .I .I loomstate fabric for loomstate fabric, both a Production Batch and an Inspection Batch are the quantity of fabric produced from one weavers beam or one continuously woven length not exceeding 20 O00 metres, provided that weft yarn of consistent and proven quality has be
25、en used If a fresh delivery of weft yarn of unproven quality is introduced during weaving the warp, a fresh NOTE batch has been created. 3.1.1.2 piece treated fabric a Finishers Batch is that which comprises one or more loomstate Production Batches, possibly comprising more than one type of fabric,
26、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. If several loomstate Production Batches are brought together during the finishing process to form one NOTE large Finis
27、hers Batch, due note should be taken of the need to maintain identification of each individual batch. 1) Published as AECMA Prestandard at the date of publication of this standard 2) In preparation at the date of publication of this standard 3) Published as AECMA Technical Report at the date of publ

If loomstate fabric is subsequently to be processed, e.g. scoured, dyed
39、or coated, allowance should NOTE 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 tolerances given in Table 1. 4.1.5.3 Length The length
40、of each roll of the product shall be: - not less than 100 m for fabric weighing 50 g/m or less; - not less than 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
41、shall not be joined by pins, metal fasteners or other means. No individual part shall be less than 10 m long. The 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 Wa

If the edge structure is not specified in the material standard, the edges shall not b

Any difference in thickness should be kept to a minimum so as not to hinder the subsequent manufacturing process. 4.1.6.4 approved for aerospace use: a) Conventional (.e. woven
45、 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) Shuttleless with the weft knitted at one selvedge with a locking thread. d) Shuttl
