Endorsement notice The text of ISO 9073-17:2008 has been approved by CEN as a EN ISO 9073-17:2008 without any modification. 1 Scope This part of ISO 9073 specifies a method for measuring the resistance of fabrics to the penetration of water by impact. The water penetration (spray impac
23、t) test is applicable to fabrics that are expected to exhibit a degree of water resistance or water repellency. The results obtained with this method depend on the water repellency of the fibres or the treatment applied to the finished material, as well as on the construction of the material. 2 Norm

26、 and definitions For the purposes of this document, the following terms and definitions apply. 3.1 water resistance of nonwoven materials fabric characteristics which are resistant to wetting and penetration by water 4 Principle This method measures the resistance of fabrics to the penetration of wa
27、ter by impact and can thus be used to predict the probable rain-penetration resistance of the fabric. The sample is used as a protective barrier covering a sheet of pre-weighed absorbent blotting paper. A specific volume of distilled or deionized water is then sprayed onto the sample and the blotter
28、 weighed again. The difference in the two weights is a measure of the amount of water passing through the barrier. The greater the difference, the more water that has passed through, i.e. the less water repellent the fabric. Thus, higher numbers indicate lower water resistance. See Annex A for gener
29、al information on reproducibility. 4 DIN EN ISO 9073-17:2008-09EN ISO 9073-17:2008 (E) 5 Materials and reagents 5.1 Blotting paper2)for spray impact penetration, 150 mm 225 mm, meeting the following parameters: a) no visible distortion in the paper when wetting while testing; b) have an absorbent ra
30、te of 5 s or less (see ISO 9073-6); c) have a minimum absorbent capacity of 480 % (see ISO 9073-6); d) exhibit uniform sheet formation; e) be traceable back to a production lot; f) have a sheet density of (0,24 0,05) g/cm3; g) have a basis weight of (124 6) g/m2; h) have a sheet thickness of 0,500 m
31、m to 0,560 mm at 10 kPa foot pressure. 5.2 Water, distilled, at a temperature of (27 1) C. 5.3 Balance, a laboratory balance capable of weighing the specimen to an accuracy of 0,01 g. 5.4 Stopwatch. 5.5 Baffle, 100 mm 100 mm cut from 6 mm thick polymethyl methacrylate plastic or an equivalent inert
32、material, to be positioned in the funnel to eliminate liquid swirling. 5.6 Drip catcher, e.g. standard blotting paper or any type of absorbent material to catch the last large drops and keep them from hitting the test specimen. 6 Apparatus 6.1 Impact penetration apparatus (impact penetration tester)
33、, as shown in Figure 1 (spray head) and Figure 2 (complete unit minus the weighed clamp). 6.2 Clamp that will clamp across the width of the specimen and which has been modified to provide a total weight of 454 g. 7 Procedure 7.1 Specimens should be sampled in accordance with ISO 3951-5. 7.2 Bring th
34、e specimens and the blotting papers from the prevailing atmosphere to moisture equilibrium for testing in the standard atmosphere as specified in ISO 139. These blotting papers should be exposed to the atmosphere on all sides (hanging on a clothes line is satisfactory). Care in handling should be ob
35、served so that specimens do not contact any contaminants, such as soap, salt, oil, etc., which might facilitate or hinder water penetration. 2) Such paper is available, for example, from Hollingsworth and Vose, Cheltenham, United Kingdom, under the reference ERTFF3. This information is given for the
36、 convenience of users of this part of ISO 9073 and does not constitute an endorsement by ISO of the product. Equivalent products may be used if they can be shown to lead to the same results. 5 EN ISO 9073-17:2008 (E) DIN EN ISO 9073-17:2008-097.3 Specimens should be cut 175 mm 325 mm, with the long
37、dimension in the machine direction. NOTE The accuracy of this procedure is highly depended on the care taken when calibrating the apparatus. 7.4 Weigh a 150 mm 225 mm piece of blotting paper to the nearest 0,01 g and designate this as the initial mass (m1). 7.5 Clamp one end of the test specimen und
38、er the 150 mm spring clamp at the top of the inclined stand. 7.6 Affix a second 150 mm clamp, modified to provide a total mass of 454 g, to the other end of the fabric specimen. 7.7 Position the pre-weighed blotting paper beneath the clamped fabric as shown in Figure 2. 7.8 Pour 500 ml of distilled
39、water, at a temperature of (27 1) C, into the funnel of the tester and allow it to spray onto the test specimen. 7.9 Upon completion of the spraying period, and at the proper time (2 s after the continuous flow stops), insert the “drip catcher” blotting paper to stop the remaining water from hitting
40、 the test area. 7.10 Lift the test specimen carefully and remove the blotting paper beneath it. 7.11 In order not to allow any evaporation loss, immediately weigh the blotting paper to the nearest 0,01 g (m2). 8 Calculation The increase in mass from m1to m2of the blotters is calculated in grams, and
41、 the individual, average and standard deviation results for each test sample are reported. 9 Test report The test report shall include the following: a) a reference to this part of ISO 9073, i.e. ISO 9073-17; b) type or designation of material tested; c) number of test pieces tested; d) testing cond
42、itions; e) individual spray impact, expressed in grams, to an accuracy of 0,01 g; f) the average and standard deviation of the spray impact, expressed in grams; g) any deviation from the standard procedure. 6 DIN EN ISO 9073-17:2008-09EN ISO 9073-17:2008 (E) Dimensions in millimetres Key 1 25 holes,

45、two types of blotting paper. The two blotting papers were type A, blotting paper that met all the test-procedure parameters, and type B blotting paper that was supplied as “routine” but did not meet any of the test-procedure requirements. It was more dense, more variable, had a slow absorbent rate a
46、nd distorted greatly when wet. Table A.1 illustrates what the six laboratories found and how the two blotting papers compared. All the observations are taken by well-trained operators using specimens randomly tested from one lot of standard material specification (SMS) material. This procedure requi
47、res the use of a blotting paper with very tight control standards, as stated in 5.1.
