7、 Committee, is one of a series of a quality suitable for aerospace purposes. It is a revision of BS8F1:1975 which is withdrawn. During its preparation changes have been made to the technical requirements: primarily, the maximum mass per unit area has been increased by10g/m 2for all fabric finishes.

8、The quality requirements specified in BSF100 have also been identified. The quality assurance authority referred to in this standard is as stated in the contract or order, or the accredited representative of the authority stated as instructed by the prime contractors. WARNING NOTE 1. This standard c

9、alls for the use of substances and/or test procedures that may be injurious to health if adequate precautions are not taken. It refers only to technical stability and in now way absolves either the supplier or the user from statutory obligations relating to health and safety at any stage of manufact

10、ure or use. WARNING NOTE 2. This standard specifies pentachlorophenyl laurate (PCPL) as the only approved rotproofing treatment for aerospace fabrics. Alternative treatments are under development, and this standard will be updated to delete PCPL as soon as an approved alternative treatment for aeros

11、pace fabrics is available. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Compliance with a British Standard does not of itself confer immunity from legal obligations. Summary of pag

21、 b) not less than 14% by boiling in the rove. 2.1.3 The yarn shall have a maximum residual alkali solubility of10.0%. 2.1.4 The weave shall be plain. 2.2 Finish The fabric shall be supplied in one of the following conditions: a) loomstate and cropped; or b) loomstate, cropped and singed; or c) finis

22、hed for doping; or d) scoured and dyed. NOTEThe finish required should be stated in the purchasers contract or order (seeA.1). 2.3 Finishing for doping NOTEIt will be necessary to obtain a standard sample from the quality assurance authority (see foreword) to carry out the required visual comparison

23、s. 2.3.1 The fabric shall be calendered to a smooth finish. 2.3.2 The doping properties shall conform to BSF100. 2.4 Dyeing Where dying is required, the colour of the fabric shall be specified either by reference to a British Standard, e.g. BS381C, or otherwise by pattern. NOTEThe requirement for dy

24、eing and the colour should be stated in the purchasers contract or order (seeA.1). 2.5 Properties of the finished fabric The finished fabric shall conform to the appropriate requirements ofTable 2. 2.6 Make up The fabric shall be delivered free from creases and either: a) lapped full width on drum b
