ISO 3994:2007(E) iv © ISO 2007 – All rights reserved Foreword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. ISO 3994 was prepared by Technical Committee ISO/TC 45, Rubber and rubber products, Subcommittee SC 1, Hoses (rubber and plastics). This third edition cancels and replaces the second edition (ISO 3994:1998), which has been technically revised. SIST EN ISO 3994:2011

ISO 3994:2007(E) © ISO 2007 – All rights reserved vIntroduction This International Standard has been prepared to provide minimum acceptable requirements for the satisfactory performance of polymer-reinforced thermoplastics hoses for suction and discharge applications, conveying water, weak aqueous chemical solutions and abrasive solids and slurries. If there is a special requirement for resistance to deleterious chemicals, this shall be a matter for agreement between the supplier and the purchaser. SIST EN ISO 3994:2011

INTERNATIONAL STANDARD ISO 3994:2007(E) © ISO 2007 – All rights reserved 1Plastics hoses — Helical-thermoplastic-reinforced thermoplastics hoses for suction and discharge of aqueous materials — Specification WARNING — Persons using this International Standard should be familiar with normal laboratory practice. This standard does not purport to address all of 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 any national regulatory conditions. 1 Scope This International Standard specifies the requirements for three types of helical-thermoplastic-reinforced thermoplastics hoses for suction and discharge of water, weak aqueous chemical solutions and abrasive solids and slurries, for use in the ambient temperature range from − 10 °C to + 55 °C. The three types of hose are for light-, medium- and heavy-duty applications. The types of hoses covered in this International Standard are not intended for use with flammable or combustible materials, nor with aromatic solvents. NOTE Hoses of a similar construction for suction and discharge for fire-fighting are specified in ISO 14557, Fire-fighting hoses — Rubber and plastics suction hoses and hose assemblies. 2 Normative references The following referenced documents are indispensable for the application of this document.
