12、d repellent properties of protection sleeve for electrical cable and cable bundles. It shall be used together with EN 6059-100. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.

14、e - Specification and test methods 1) 3 Terms and definitions A specimen with a length of 40 mm to 60 mm shall be used. For tubular sleeves only, the specimen shall be prepared as a flat part by cutting through the sleeve in longitudinal direction. The cutting area shall be fixed by application of t

15、ape or adhesive to avoid debraiding of the specimen (if applicable). If water is used, it shall be distilled or demineralised water according to ISO 3696 Type 2. 4 Apparatus To achieve a controlled drip a bottle or a pump shall be used. It shall be provided with a minimum drip aperture of 2,5 mm. Th

16、e fixture to apply the specimen and bottle or pump with a drip aperture as given in figure 1 shall be used. The distance between the aperture and the specimen shall be minimum 70 mm. The number of drops delivered per minute should be comprised between 20 to 25 and the volume of water delivered per m

17、inute of a minimum of 1,35 ml. 1) Published by: International Organization for Standardization (ISO), https:/www.iso.org/ prEN 6059-305:2017 (E) 4 Key 1 Specimen under test 2 Piece of absorbing material under the specimen 3 70 mm minimum between aperture and specimen Figure 1 Equipment for fluid abs

18、orption test 5 Method The test shall be carried out with fluids specified in the product standard. The specimen shall be placed on exposure table which is covered with a dry piece of absorbing material. At the place of dripping, the specimen shall contact the piece of absorbing material with a load

19、as less as possible. The specimen shall be maintained flat and in contact on the absorbing material in the dripping area by applying pressure on both sides of the specimen but no specific pressure in the dripping area. Piece of absorbing material used to record water intake should change colour or s

20、hade on contact with water. The drip frequency shall be adjusted between 20 and 25 drips/min. If a bottle is used, it shall be filled regularly. 6 Requirements The piece of absorbing material shall be free of the fluid after the drip time which is specified in the product standard. The results shall be recorded within 5 minutes following the end of the dripping. Except otherwise specified in product standard, when marking on cores is performed, each core shall be marked with its own designation.
