EN 16057:2012 (E) 3 Foreword This document (EN 16057:2012) 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of an identical text or by endorsement, at the latest by November 2012, and conflicting national standards shall be withdrawn at the latest by November 2012. 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 European Standard is one of a series of test methods which support associated product standards. In respect of potential adverse effects on the quality of water intended for human consumption caused by metallic materials, attention is drawn to the fact that the relevant national regulations remain in force until the adoption of verifiable European acceptance criteria. Water intended for human consumption is hereafter referred to as "drinking water" and means the same as the definition given at Article 2(1) of the Council Directive 98/83/EC on the quality of water intended for human consumption. This document describes a test method to determine the presence of lead (Pb) on the surface of copper alloys. 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, France, Germany, Greece, Hungary, Iceland, Ireland, Italy, Latvia, Lithuania, Luxembourg, Malta, Netherlands, Norway, Poland, Portugal, Romania, Slovakia, Slovenia, Spain, Sweden, Switzerland, Turkey and the United Kingdom.

EN 16057:2012 (E) 4 Introduction During processing of lead containing copper alloys a lead film might be formed on the surface of the material. These lead layers depend on the individual manufacturing process at the different production sites. The lead film on the inner surface of products will cause a lead release into the drinking water in the first weeks after a new product comes in contact with drinking water (short term behaviour).
The lead release from the bulk material is not affected by the lead film on the surface and depends on the composition of the material. The bulk material can release lead for a long period (long term behaviour). It is possible to test materials for their lead release from the bulk material (EN 15664-1 and -2), so that products made of approved materials do not have to be tested for this characteristic. As the lead films on the surface depend on the individual manufacturing process, it is necessary to test the products or the manufacturing process. This test method is intended to be used as a process control method to assess the presence of lead films on the inner surface of products intended to come in contact with drinking water or to assess the efficiency of a manufacturing process to remove or minimise surface Pb, e.g. washing process to remove lead on surfaces. The implementation of an audit controlled process monitoring is an effective w
