EN 14987:2006 (E) 3 Foreword This document (EN 14987:2006) has been prepared by Technical Committee CEN/TC 249 "Plastics", the secretariat of which is held by IBN/BIN. 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of an identical text or by endorsement, at the latest by May 2007, and conflicting national standards shall be withdrawn at the latest by May 2007. According to the CEN/CENELEC Internal Regulations, the national standards organizations of the following countries are bound to implement this European Standard: Austria, Belgium, Cyprus, Czech Republic, Denmark, Estonia, Finland, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland and United Kingdom.



EN 14987:2006 (E) 4 1 Scope This European Standard specifies test methods and criteria which are to be applied in order to verify if a solid plastic material can be considered as disposable in waste water treatment plants, i.e. it does not create problems for the environment and for the drainage systems. In order to reach this conclusion it needs be verified that the plastic material under evaluation is biodegradable under aerobic conditions (i.e. susceptible to mineralization) and water soluble or water dispersible. NOTE Plastic materials which are shown to be in compliance with this European Standard can be used to produce items which, for their characteristics of water solubility or water dispersibility and biodegradability, can be eventually disposed of in municipal or industrial waste water treatment plants, through the sewage. 2 Normative references The following referenced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies.
