4、oses” (Secretariat: BSI, United Kingdom) in collaboration with Technical Committee ISO/TC 45 “Rubber and rubber products”, Subcommittee SC 1 “Hoses (rubber and plastics)”, in accordance with the Agreement on technical cooperation between ISO and CEN (Vienna Agreement). The responsible German body in
5、volved in its preparation was the Normenausschuss Feuerwehrwesen (Firefighting and Fire Protection Standards Committee), Technical Committee NA 031-04-04 AA Schluche und Armaturen. DIN EN ISO 14557 has been published as a consolidated edition incorporating Amendment A1:2007 into DIN EN ISO 14557:200
6、3-03. The beginning and end of text passages that have been added or modified by Amendment A1:2007 are indicated by ! and “, respectively. Together with DIN EN 694, DIN EN 1947 and DIN EN 14540, this standard is one of a four-part series of firefighting standards that have been developed by CEN/TC 1
7、92/WG 1. Since 2001 this series has been gradually adopted at national level, whereby all conflicting national standards have had to be withdrawn. Because this series of European Standards takes into consideration all suction hoses currently in use in Europe, rubber and plastics suction hoses as in
8、this standard have been classified into two types, and fourteen possible inside diameters are given. During the next revision of this European Standard, a review based on market considerations will show whether or not this extensive classification will continue to be necessary. DIN designation EN IS
9、O 14557:2002 + A1:2007 does not specify a designation. The following designation of hoses as in this standard is recommended: EXAMPLE Designation of a suction hose as in DIN EN ISO 14557, type A, with an inside diameter of 110 mm, an unassembled length of 1 500 mm, with couplings (K): Hose DIN EN IS
10、O 14557 A 110 1500 K National Annex NA lists which hoses as in this European Standard should be used to replace hoses as in the former DIN 14810 (withdrawn); the couplings to be used with such hoses are given in National Annex NB. The DIN collective mark may be applied to hoses complying with this s
11、tandard if they have been registered by DIN CERTCO. NOTE 1 Use of the collective mark requires registration by DIN CERTCO Gesellschaft fr Konformitts-bewertung mbH, Alboinstr. 56, 12103 Berlin. NOTE 2 is a registered trademark of DIN. The DIN Standards corresponding to the International Standards re
12、ferred to in clause 2 of the EN are as follows: ISO 176 DIN EN ISO 176 ISO 1307 DIN EN ISO 1307 ISO 1402 DIN EN ISO 1402 ISO 1746 DIN EN ISO 1746 ISO 4672 DIN EN ISO 4672 DIN EN ISO 14557:2008-01 3 ISO 7233 DIN EN ISO 7233 ISO 7326 DIN EN 27326 ISO 8033 DIN EN ISO 8033 ISO 8330 DIN EN ISO 8330 ISO 1

DIN shall not be held responsible for identifying any or all such patent rights. Amendments This standard differs from DIN EN ISO 14557:2003-03 as follows: a) T
14、he National Foreword and the CEN Foreword have been modified. b) A note has been added to the effect that the bending resistance test is only suitable for hoses with an ID up to 80 mm. c) The term “type approval test” has been replaced by the term “type test”. d) Repeat type tests are now to be carr
15、ied out every five years. e) Annex F specifying type, production and batch tests has been divided into two annexes: 1) Annex F (normative) “Type testing and production testing”, and 2) Annex G (informative) “Batch testing”, which serves as a guideline only.

To ensure the compatibility of all fire extinguishing components used in Germany, the following couplings are to
21、be used with hoses as in this European Standard. In Germany, suction hoses not included in the preferred series given in Table NA.1 shall also be compatible with the couplings in Table NB.1, or where the internal diameter deviates from those in Table NA.1 couplings shall be selected that are suitabl
22、e to that diameter or they shall be altered to fit the hose so that a secure coupling and proper functioning of the suction line is ensured in all cases.
