Similarly, each raw material batch shall be traceable to all products at all stages of manufacture and delivery. 4.1.3 Freedom from defects
36、 All products shall be free from defects not complying with the requirements of the material standard or order and this technical specification, or which may be prejudicial to the subsequent manufacture and/or use of the products. The requirements for freedom from defects are given in Annex B of thi
37、s specification. Marking media to be used for the identification of defects on textiles shall conform to the requirements of Annex C 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 conformity wi
38、th any European, National or local lawdregulations. 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 5.5. If loomstate fabric is subs
39、equently to be processed, e.g. scoured, dyed or coated, allowance should NOTE be made for the consequent shrinkage. 4.1.5.2 Overall width When measured in accordance with the test method listed in Annex A, the width of the fabric shall be not less than that specified in the individual textile specif
40、ication. The variation in width shall not exceed 15 mm. 4.1.5.3 Length When measured in accordance with the EN 1773 the length of the product shall conform to the following. a) Fabric for coating shall consist of continuous lengths without gross defects and with not more than one butt seam per 200 m
41、 length. No part shall be less than 40 m long. b) For other fabrics the minimum length of the loomstate piece shall be 100 m for those having a mass per unit area of 450 g/m2 or less, and 50 m for those having a mass per unit area of more than 450 g/m2. Not more than 5 % of the pieces shall be in th

NOTE Certain weaving processes generate selvedges that may b
44、e slightly thicker than the body of the fabric. Any difference in thickness should be kept to a minimum so as not to hinder the accurate cutting of panels from multiple layers of fabric. 4.1.6.3 The fabric shall lie flat on a table. 4.1.6.4 lengthways tension, and weft skew and bow shall conform to
