6、 BSI 10-1999 Foreword This British Standard is one of a series for textiles of a quality suitable for aerospace purposes and constitutes a revision of BS 2F116:1975, which is withdrawn. It differs from the previous edition in that the quality requirements specified in the latest edition of BS F100 h
7、ave been identified. NOTEThe latest revision of an Aerospace Series standard is indicated by a prefix number. This standard specifies pentachlorophenyl laurate (PCPL) as a rot-proofing treatment. Alternative treatments are under development, and this standard will be updated to delete PCPL as soon a
8、s a suitable alternative treatment for aerospace materials is available. WARNING. This standard calls 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 suitability and in no way absolves either the supp
9、lier or the user from statutory obligations relating to health and safety at any stage of manufacture or use. 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
10、 Standard does not of itself confer immunity from legal obligations. Summary of pages This document comprises a front cover, an inside front cover, pagesi andii, pages1 and2, an inside back cover and a back cover. This standard has been updated (see copyright date) and may have had amendments incorp
11、orated. This will be indicated in the amendment table on the inside front cover.BS3F116:1995 BSI 10-1999 1 1 Scope This British Standard specifies requirements for a range of mercerized cotton fabrics for aerospace purposes, primarily for parachute canopies. 2 References This standard incorporates,
12、by dated or undated reference, provisions from other publications. These normative references are made at the appropriate places in the text and the cited publications are listed on the inside back cover. For dated references, only the edition cited applies; any subsequent amendments to or revisions
13、 of the cited publication apply to this standard only when incorporated in the reference by amendment or revision. For undated references, the latest edition of the cited publication applies, together with any amendments. 3 General In addition to the requirements specified in clauses4 to10 of this s
14、tandard, the requirements and tests of BS F100, as listed in Table 1, shall apply. 4 Yarn 4.1 The fabric shall be manufactured from unsized cotton yarn. 4.2 The yarn shall be two-fold and shall be mercerized. NOTEYarn plied from singles of104 dtex has been found suitable for both warp and weft. 5 We
15、ave The weave shall be plain. 6 Finish The fabric, or the yarns from which it is to be woven, shall be rendered rot-resistant by treatment with pentachlorophenyl laurate (PCPL) in accordance with BS2087-1:1992, normal process. 7 Construction and properties The finished fabric shall conform to Table
16、2.

20、Table 3, or shall conform to8.2. NOTEIt is most desirable that the average permeability of the fabric be as near as possible to the relevant mean figure shown in Table 3, and that the variation between the individual readings be low. Table 3 Air permeability test requirements 8.2 If the average perm
21、eability does not conform to Table 3 but is equal to the relevant lower value or the relevant higher value given in Table 4, then two further series of ten readings each shall be taken in different locations on the same piece. The average of each series shall be not less than the relevant lower valu
22、e, nor more than the relevant higher value, given in Table 4. All individual readings included in any of the averages shown in Table 4 shall be within the respective limits given in Table 4. 8.3 The proportion of fabric which does not conform to Table 3 shall not exceed5% of any batch tested. 8.4 Th
23、e manufacturer shall maintain quality-control sheets to provide evidence that the average level and the variability of air permeability meet the requirements of8.1 to8.3. 9 Packaging The fabric shall be made up at full width, on poles longer than the width of the fabric or on suitable tubes having a
24、 length equal to the width of the fabric. It shall be made up in continuous pieces without joins, rolled tightly and free from creases. 10 Identification The following information, supplied by the purchaser to identify the fabric for ordering purposes, shall be fully documented: a) the number of thi
25、s British Standard, i.e.BS3F116; b) the relevant designation given in Table 2. NOTEThis identification may be codified; e.g.fabric no.633 may be identified as BS 3F116633.
