Table 1 -Tests 15 I Moisture content 1% I EN IS0 3344 I For assembled aramid fibre filament yams the determination of the differences
31、in length of the individual yarns shall be determined according to the method described in annex A of this standard. 4.2 Visual properties The para-aramid fibre filament yarns shall be free from oil, grease and other contaminants as well as from partial tow breakage and fluffy debris on the surface
32、of or within the bobbin, which are incompatible with required processing conditions. 4.3 Other properties Spikes Distinction shall be made between blown splices and bonded splices. Type and number shall be agreed between the yam manufacturer and the customer. 5 Quality inspection The tests to be per
33、formed on a lot (or batch) of para-aramid fibre filament yarn will be different depending whether they are for a reception lot or a production lot. One production lot is obtained by a fabrication campaign of limited duration in time on basis, for example, on the basis of one given amount of raw mate
34、rial. One reception lot, as received by a customer can be made from one part or the whole of one production lot. It may also originate from several production lots.

35、mpiing and criteria for acceptance In the context of this standard, the sampling method by ATTRIBUTES is proposed, though it is also possible to use sampling by variables. The evaluation of a lot of para-aramid fibre filament yarn is based on the sampling that is described in the standard EN IS0 188
36、6 or IS0 2859-1 and on the acceptance quality level (AQL) of 13 % for the physical properties and 2,5 % for the visual properties. Depending on the circumstances, the control for the evaluation of a lot, may be either with a “normal” inspection level (for the qualification of a product or in the cas
37、e of problems), or with a “reduced” inspection level, when a minimum of three successive controls have given an acceptable result. Tables 2 and 3 show the procedure for inspection by attributes with the normal test plan (Table 2) and the reduced test plan (Table 3). Table 2 - Test plan - normal insp

NOTE For batches or more than IO o00 elementary units. sampling shall be- the subject of an agreement between the yam manufacturer and lhe customer. 5.2 Ttsing at manufacturer The manufacturer s
40、hall ensure that the shipped product meets a given specification. Therefore he has to define a quality control system which will generally include process control (SPC) and testing of final and semi products with adequate test frequency. On the basis of the knowledge of the process and implementatio
41、n of SPC, possibly combined with the use of automated production equipment, the testing at the manufacturer will generally be done using a reduced sampling compared with that used for the reception of lots, with a trend toward testing of process variables in 5.3 Certificate The supplier may at the r
42、equest of the customer issue a certificate for any shipment. This can be: - a certificate of conformance, which is a document confuming that the material has been controlled and meets the requirements of the specification; - a certificate of analysis, which, besides the statement above also includes
43、 the test result on the applicable material; - a draft of a certificate of analysis is given in annex B of this standard. 6 Mode of delivery 6.1 Packaging Unless otherwise explicitly specified, the para-aramid fibre filament yarns shall be shipped in boxes, adequately supported and protected to prev
44、ent damage during normal transit and storage. O BSI 09-1999 Page 8 EN 13003-2:1999 6.2 Marking of packages Para-aramid fibre filament yams shall be marked in a clearly visible and legible way on each bobbin and on the exterior package with the following information: - on each bobbin: trade designati
45、on; - on the packed unit: - trade designation; - net weight; - name of manufacturer; - manufacturers production and traceability reference, including the lot No. 7 Storage Para-aramid fibre filament yams in their original packaging shall be stored in dry locations at a storage temperature of 23 OC f
46、 5 OC and a relative humidity of 60 % r.h. f 5 % r.h Under these storage conditions the shelf life of the para-aramid fibre filament yarns will be a minimum of 3 years, counted from the production date. The advice of the manufacturer should be sought on the expected shelf life under other storage co
47、nditions. Annex A (normative) Para-aramid fibre filament yarns: Determination of the differences in length of multiple-wound yarns A.l Scope and field of application This test method specifies a procedure for the determination of the differences in length of individual yams in multiple-wound aramid
48、fibre filament yams. A.2 Denition The difference in length is evaluated on the basis of the difference in sagging (a on Figure A. 1) between the maximum and minimum sag of the individual aramid fibre filament yams. This difference in sagging is measured and expressed in mm. This property can also be
49、 identified by the term: “catenary”. A3 Prlncfple of the method 15 m of yam taken from the bobbin under test are arranged horizontally and stressed to 12,7 mN/tex at one end. The differences in yam length are given by the difference between the maximum sag of the individual aramid fibre filament yarns. A.4 Apparatus The test apparatus consists of the following parts to be arranged as shown in Figure A. 1 : - two stands, approx. 1 200 mm high. A rubber-faced clamp is fixed to one stand and a pulley attached to the other; - movable rubbergaced clamp, capable o
