EN 15889:2011 (E) 4 Foreword This document (EN 15889:2011) has been prepared by Technical Committee CEN/TC 192 “Fire service equipment”, the secretariat of which is held by BSI. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by January 2012, and conflicting national standards shall be withdrawn at the latest by January 2012. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This European Standard details hose and hose assembly test methods collated mainly from published EN fire hose standards. Although no technical changes have been introduced, some changes to the format of the test methods had to be made to enable them to be included in this European Standard. The published EN fire-fighting hose standards will be revised to remove the test method annexes following the publication of this European Standard. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and the United Kingdom.

EN 15889:2011 (E) 5 1 Scope This European standard specifies test methods for lay-flat fire-fighting hoses for fixed systems, semi-rigid fire-fighting hoses for both fixed systems and vehicles and fire-fighting suction hoses for vehicles. These test methods are required for the standards for fire-fighting hose product standards developed by CEN/TC 192. Consequently, the applicable test methods are selected and the requirements and test values defined in the relevant fire-fighting hose product standards and normatively referenced in those standards. This European Standard does not cover test methods for lay-flat fire-fighting hoses for vehicles for which no European standard exists. NOTE Annex R (informative) lists the existing published ISO and EN hose test methods standards that are specified within fire-fighting hose standards. 2 Normative references The following referenced documents are indispensable for the application of this document.

Make two parallel cuts at right angle to the hose axis (25 ± 0,5) mm apart, taking care not to cut through the yarns. Separate a layer for a distance sufficient to enable the separated end to be held in the grips of the test machine (see Figure B.1). Dimensions in millimetres

Kink pressure test (lay-flat and semi-rigid fire-fighting hoses) C.1 Test piece Cut a test piece of 2,0 m length from the hose. C.2 Apparatus C.2.1 Source of hydrostatic pressure, with water as the test medium, capable of maintaining the specified pressure. C.3 Procedure Connect the test piece to the pressure source and fill with water, expelling all air before securely clamping shut the free end of the hose. Maintain a pressure of 0,07 MPa in the test piece while bending it through 180° at a point approximately midway along its length. Tie the free end of the hose back on itself, as close as possible to the secure end, so as to form a sharp kink, ensuring that the tie does not prevent subsequent expansion of the diameter of the test piece. Raise the pressure in the test piece to the specified pressure over a period of 60 s. Maintain the pressure for 60 s. Examine the test piece for any sign of leakage or damage prior to releasing the pressure. C.4 Test report The test report shall include the following information:  full description of the hose tested;  reference to this test method;  any evidence of leakage or damage observed;  date of the test.

Accelerated ageing test D.1 Lay-flat fire-fighting hoses D.1.1 Test piece Cut four test pieces from the hose each of 1 m in length. NOTE It is recommended that the test pieces should be taken from the same hose sample from which the test pieces for the burst pressure tests and adhesion tests were taken. This will allow an exact comparison to the changes before and after the artificial ageing. D.1.2 Apparatus D.1.2.1 A temperature controlled oven as specified in ISO 188:2007. D.1.3 Procedure Bend three of the test pieces through 180° at a point approximately midway along their length and tie in this flaked position. Loosely coil the remaining test piece. Age all four test pieces in air for 14 days at a temperature of (70 ± 1) °C in a temperature controlled oven as specified in ISO 188:2007. After ageing, straighten out the three flaked test pieces and subject them to the burst pressure test as specified. Subject the remaining test piece to the adhesion test as specified in relevant fire hose standard.

The three test pieces subjected to the burst pressure test shall conform to the requirements of relevant fire hose standard. The resultant adhesion of the fourth test piece shall be in accordance with the requirements in relevant fire hose standard.

Age the test pieces in air for 7 days at a temperature of (70 ± 1) °C in a temperature controlled oven as specified in ISO 188:2007. After ageing, subject three of the test pieces to the burst pressure test as given in the relevant fire hose standard. Subject the remaining test piece to the adhesion test as given in the relevant fire hose standard.

Surface abrasion resistance test (semi-rigid fire-fighting hoses) E.1 Test pieces Cut five test pieces of hose, each 0,35 m in length. E.2 Apparatus E.2.1 Test machine (see Figure E.1) for abrading the surface of a pressurized rotatable test piece with a laterally moveable abrading strip which is continually renewed. The driven rotating coupling is fixed in the axial direction whereas the other coupling can be moved axially in a guide. The abrasion arm is in the form of a rocker pivoted to swivel upwards, and the weight of the arm is such that a force of 105 N acts on the test piece when it is set horizontally. This abrasion arm reciprocates along the hose axis at a rate of between 18 mm/s to 20 mm/s over a distance of 80 mm with the direction of travel being changed automatically. The pause time at the reversal points shall not exceed 0,1 s in each case. The abrasion arm carries the abrading strip which moves 4 mm along the hose length for each double stroke, and the test piece is supported midway along its length by plain rollers. E.2.2 Air pressure vessel with a capacity of at least 2 l fitted to the test machine to retain the pressure in the event of a loss of water. E.2.3 Abrasive material consisting of a roll of corundum twill abrasive cloth measuring 50 mm wide and approximately 50 m long. The abrasive used for this abrasive material shall be synthetic 15, good quality fused aluminium oxide (Al2O3) with a minimum Al2O3 content with mass fraction of 70 %. It shall have a grain size of 60P as specified in the Grain Size Standard (43-1984 rev 1993) of the Federation of European Producers of Abrasive Products (FEPA). SIST EN 15889:2012
