25、is International Standard should be familiar with normal laboratory practice. This standard does not purport to address all the safety problems, if any, associated with its use. It is the responsibility of the user to establish appropriate health and safety practices and to ensure compliance with an
26、y national regulatory conditions. 1 Scope This International Standard specifies the requirements for three types of general-purpose textile-reinforced rubber water hose with an operating temperature range of 25 C to +70 C and a maximum working pressure of up to 25 bar 1). These hoses are not intende
27、d to be used for conveyance of potable (drinking) water, for washing-machine inlets, as firefighting hoses, for special agricultural machines or as collapsible water hoses. These hoses may be used with additives which lower the freezing point of water. 2 Normative references The following referenced

32、ns For the purposes of this document, the terms and definitions in ISO 8330 apply. 4 Classification Hoses are designated as one of the following types depending on their pressure rating: Type 1: Low pressure Designed for a maximum working pressure of 6 bar. Type 2: Medium pressure Designed for a max
33、imum working pressure of 10 bar. Type 3: High pressure Designed for a maximum working pressure of 25 bar. 5 Materials and construction The hose shall consist of: a rubber lining; a reinforcement of natural or synthetic textile, applied by any suitable technique; a rubber cover. The lining and cover
34、shall be of uniform thickness, concentric to comply with the minimum thickness specified, and free from holes, porosity and other defects. The cover finish may be smooth, fluted or fabric-marked. 6 Dimensions 6.1 Internal diameters and tolerances When measured in accordance with ISO 4671, the intern
35、al diameters and their tolerances shall conform to the values specified in Table 1. 6.2 Concentricity When determined in accordance with ISO 4671, the concentricity, based on a total indicator reading between the internal diameter and the outside surface of the cover, shall be no greater than 1,0 mm
36、 for hoses of internal diameter up to and including 76 mm, and no greater than 1,5 mm for hoses of inside diameter greater than 76 mm. 6.3 Tolerance on length When measured in accordance with ISO 4671, the tolerance on cut lengths shall be as specified in ISO 1307. 6.4 Minimum thickness of lining an
37、d cover When measured in accordance with ISO 4671, the minimum thickness of the lining plus cover shall be 1,5 mm. If the cover is fluted, the depth of the flutes shall not be greater than 50 % of the cover thickness. 5 DIN EN ISO 1403:2010-04 EN ISO 1403:2008 (E) Table 1 Internal diameters and tole
