EN 1406:2017 (E) 4 European foreword This document (EN 1406:2017) has been prepared by Technical Committee CEN/TC 164 “Water supply”, the secretariat of which is held by AFNOR. This European Standard shall be given the status of a national standard, either by publication of an identical text or by endorsement, at the latest by May 2018 and conflicting national standards shall be withdrawn at the latest by May 2018. Attention is drawn to the possibility that some of the elements of this document may be the subject of patent rights. CEN [and/or CENELEC] shall not be held responsible for identifying any or all such patent rights. This document supersedes EN 1406:2009. The significant technical difference between this edition and EN 1406:2009 is a wider possible degree of substitution. The main modifications are as follows: — Subclause 3.1.4 empirical formulae; — Subclause 3.1.5 chemical formulae; — Subclause 3.3.2 density; — Subclause 3.3.3 solubility; — Subclause 4.2 composition of commercial product; — Subclause A.1.2 manufacturing process; — Subclause A.2.2 form in which it is used. Annex A is informative and gives some information on origin, use and handling of modified starches. According to the CEN-CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Bulgaria, Croatia, Cyprus, Czech Republic, Denmark, Estonia, Finland, Former Yugoslav Republic of Macedonia, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Serbia, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.
