20、mittee 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 withd

21、rawn 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 assem

22、bly 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 rev

23、ised 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, C

25、e 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 standa

26、rds 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-fi

27、ghting 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

28、application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.

39、se cover thickness (lay-flat fire-fighting hoses) A.1 Test piece Cut a ring sample from the hose and measure the distance between the top of the yarns and the surface of the cover at four equidistant points around the ring using the optical magnifier. A.2 Apparatus A.2.1 Optical magnifier, with a sc

40、ale graduated in 0,01 mm divisions. A.3 Procedure Calculate the mean of the four measurements to obtain the cover thickness value. Where the cover is variable or ribbed, the measurements shall be made at the thinnest point. A.4 Test report The test report shall include the following information: ful

41、l description of the hose tested; reference to this test method; cover thickness; date of the test. BS EN 15889:2011EN 15889:2011 (E) 8 Annex B (normative) Adhesion test (lay-flat fire-fighting hoses) B.1 Test piece Cut a ring (50 2) mm wide from the hose at right angles to its longitudinal axis. Cu

42、t the ring transversely and open it to form a strip. 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)

B.3 Procedure When tested in accordance with type 1 of EN ISO 8033:2006 the adhesion between lining and jacket shall be as specified in the rele

44、vant fire hose standard. If an adhesion result is not possible because of tearing due to high adhesion, this shall be accepted as a pass. All adhesions shall be attempted and the results recorded.

46、ength 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

47、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 ex

48、pansion 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.
