The work
6、 of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmen
7、tal, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The ma
8、in task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. At
9、tention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 18695 was prepared by Technical Committee ISO/TC 38, Textiles, Subcommittee SC 2, Cleansing, finish
10、ing and water resistance tests. BS ISO 18695:2007blank1Textiles Determination of resistance to water penetration Impact penetration test 1 Scope This International Standard is applicable to any textile fabric, which may or may not have been given a water-resistant or water-repellent finish. It measu
11、res the resistance of fabrics to the penetration of water by low impact, and thus can be used to predict the probable rain penetration resistance of apparel fabrics. The test is best suited for fabrics of medium to loose construction where the Bundesmann rain-shower test (ISO 9865), or Rain Test (IS
12、O 22958) is too severe. Fabrics that do not lie flat under tension are not applicable. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of
13、 the referenced document (including any amendments) applies. ISO 139, Textiles Standard atmospheres for conditioning and testing 3 Terms and definitions For the purposes of this document, the following terms and definitions apply. 3.1 water resistance characteristic of resisting wetting and penetrat
14、ion by water 4 Principle A volume of water is allowed to spray from a height of (610 10) mm against a taut surface of a test specimen backed by a weighed blotter. The blotter is then reweighed to determine water penetration and the specimen is classified accordingly. 5 Safety Precautions Good labora
15、tory practises should be followed. Wear safety glasses in all laboratory areas. NOTE These safety precautions are for information purposes only. The precautions are ancillary to the testing procedures and are not intended to be all inclusive. It is the users responsibility to use safe and proper tec
16、hniques in handling materials in this International Standard. Manufacturers should be consulted for specific detail such as material safety sheets and other manufacturers recommendations.

Clamp another (152 10) mm clamp, of (0,45 0,05) kg total weight, to the free end of the test specimen. Weigh a standard paper blotter (152 10) mm (229 10) mm to the nearest
20、 0,1 g and insert beneath the specimen. 10.2 Pour (500 10) ml of distilled water (6.1) into the funnel of the tester and allow to spray on to the test specimen. The water should be poured into the funnel without imparting any swirling motion to the water in the funnel. 10.3 Upon completion of the sp
21、raying period (2 s after continuous flow stops), carefully lift the test specimen, remove the blotter, then quickly reweigh to the nearest 0,1 g. 1) Impact Penetration Tester is the name of a suitable product available from AATCC, P O Box 12215, Research Triangle Park, NC 27709-2215 (tel: 1-919-549-
