Ta mednarodni standard določa zahteve za tri vrste s termoplastično spiralo ojačenih termoplastičnih cevi za sesanje in odvajanje vode, šibkih vodnih kemičnih raztopin in abrazivnih trdnih in tekočih zmesi, ki se uporabljajo v območju okoljske temperature med 10 °C in 55 °C. Tri vrste cevi so namenjene uporabi pri lahki, srednji in težki obremenitvi. Vrste cevi, ki jih zajema ta mednarodni standard, niso primerne za uporabo z vnetljivimi ali gorljivimi materiali in z aromatskimi topili.

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

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
