23、57:2002 (E) 4 Foreword This document (EN ISO 14557:2002) has been prepared by Technical Committee CEN/TC 192 “Fire service equipment“, the secretariat of which is held by BSI, in collaboration with Technical Committee ISO/TC 45 “Equipment for fire protection and fire fighting“. This European Standar
24、d shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by June 2003, and conflicting national standards shall be withdrawn at the latest by June 2003. Recommendations on the frequency at which tests specified in this standard s
25、hould be carried out are given in annex F. Users of this standard are advised to consider the desirability of independent certification of product conformity with this standard based on testing and continuing surveillance, which may be coupled with assessment of a suppliers quality systems against E
26、N ISO 9001. The annexes A to E and Z are normative. Annex F is informative. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Czech Republic, Denmark, Finland, France, Ge
27、rmany, Greece, Iceland, Ireland, Italy, Luxembourg, Malta, Netherlands, Norway, Portugal, Spain, Sweden, Switzerland and the United Kingdom. Introduction This European Standard is mainly concerned with fire service suction hoses for fire-fighting, used manually to supply unpressurized water to the p
28、ump. Licensed Copy: sheffieldun sheffieldun, na, Sat Nov 18 02:20:23 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN ISO 14557:2002 (E) 5 1 Scope This European Standard gives requirements and test methods for rubber and plastics suction hoses for fire-fighting purposes. NOTE 1All pressures are express
29、ed in megapascals. 1 MPa = 10 bar. Additional requirements are specified for hose assemblies, that is, hoses with couplings already fitted, where this is carried out by the hose manufacturer (see clause 8). Type A (Rubber) hoses are intended for use at a minimum temperature of -20 ?C and Type B (The
30、rmoplastics) hoses are intended for use at a minimum temperature of -10 ?C. NOTE 2Hoses for use at temperatures lower than those specified above can be supplied by agreement between the manufacturer and purchaser. In this case, the low temperature flexibility test (see 6.3) should be carried out at
31、the specified temperature. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text, and the publications are listed hereafter. For dated references, subseq
32、uent amendments to or revisions of any of these publications apply to this European Standard only when incorporated in it by amendment or revision.

36、at Nov 18 02:20:23 GMT+00:00 2006, Uncontrolled Copy, (c) BSI EN ISO 14557:2002 (E) 6 3 Terms and definitions For the purposes of this European Standard, the terms and definitions for working pressure, proof pressure and burst pressure given in ISO 8330 apply. 4 Classification 4.1 Type (hose constru
37、ction) Type A hoses shall consist of: a) a rubber lining uniform in thickness, reasonably concentric and free from holes, porosity and other defects; b) a textile reinforcement applied uniformly by any suitable method; c) an embedded wire helix or helices evenly and uniformly applied and made from m
38、etallic material that allows the hose to meet the specification requirements; d) a rubber cover, ozone resistant, uniform in quality and thickness and free from defects. Type B hoses shall consist of a flexible, thermoplastics material supported in its mass by a helix of rigid polymeric material. Th
39、e reinforcement and flexible components of the hose wall shall be fixed and free from cracks, porosity, foreign inclusions or other defects. 4.2 Hose ends The hose ends shall be compatible with suction hose couplings conforming to the relevant national standards. NOTEWhere soft ends or wire-free end
40、s are used for type A hoses, they should have an additional rubberized textile reinforcement applied as a cuff over the wire-free portion and the first turn of the embedded wire helix. The hose ends should be capped or sealed to prevent ingress of water. Specifying the dimensions of the soft or wire
41、-free ends may be the subject of an agreement between the manufacturer and the purchaser. 5 Dimensions, tolerances and maximum mass 5.1 Inside diameter and maximum mass The dimensions of the hose and tolerances, when measured in accordance with ISO 4671, shall conform to the requirements given in Ta
42、ble 1. The mass per metre length of the hose shall be in accordance with Table 1.

Tolerances on length shall be in accordance with ISO
45、1307. Tolerances for fixed hose lengths shall be specified by agreement between the purchaser and the manufacturer. 6 Performance requirements of finished hose 6.1 Hydrostatic requirements NOTEThe hydrostatic requirements given below are for suction hoses only. Hoses intended for use in discharge du
46、ties as well, require higher burst and proof pressures to be specified by agreement between the purchaser and the manufacturer. 6.1.1 Deformation under proof pressure When tested in accordance with ISO 1402 at temperatures and pressures shown in Table 2, the hose shall not burst or show any evidence
47、 of leakage, cracking, abrupt distortion or other signs of failure.
