- September 2011 - Quality of water intended for human consumption.

In 1998 the European Union published Council Directive 98/83/EC “On the quality of water intended for human consumption”, commonly known as the Drinking Water Directive or DWD. The objective of the DWD is to protect the health of the consumers in the European Union and to make sure the water is wholesome and clean. To make sure drinking water everywhere in the EU is healthy, clean and tasty, the DWD sets standards for the most common substances (so-called parameters) that can be found in drinking water. In the DWD a total of 48 microbiological and chemical parameters must be monitored and tested regularly. The limits will be enforced in 2013. Many metallic elements are covered by the DWD, including lead and nickel. According to the Directive, the maximum concentration of lead in drinking water will be reduced to 10 µg/l from the current limit of 25 µg/l. This is a significant development: in order to be prepared, the European brass rod industry has coordinated its efforts to present to the regulators responsible for drinking water a list of alloys (to be known as the Hygienic Copper Alloys List) that will respect the DWD 2013 limits. This list contains many alloys already in use and a few new ones. In order to comply with the new limits of the Drinking Water Directive, every alloy in the list, whether in current use or a new alloy, must pass a migration test. The test is carried out in three different types of water and takes about 6 months to be completed. On the regulators side, the country that plays a key role is Germany under the mandate of the 4MS Group (the four Member States are: France, Germany, Netherlands and United Kingdom), and the German Environmental Agency (Umweltbundesamt) acts as the coordinator of the whole project. Furthermore, the next revision of the German Standard DIN 50930-6 “Corrosion of metals - Corrosion of metallic materials under corrosion load by water inside of tubes, tanks and apparatus. Part 6: Influence of the composition of drinking water” will soon be in Europe. The idea is that this DIN Standard will not mention specific alloys but will make reference to the “Hygienic Copper Alloys List”. The advantage of this approach is that in case there is a need to add a new alloy, it will not be necessary to revise the DIN 50930-6 Standard. The draft of the Hygienic Copper Alloys List in German is available here: >Hygienic Copper Alloys List

- - May 2011 - NSF Certification

Trafilerie Carlo Gnutti announces a change in its NSF International Approval in relation to California Health and Safety Code 116875 concerning the content of Lead (also known as AB 1953) for its alloys named CW509L 02 (OT60-USA), CW510L (OT57-USA) and CW511L (ADZ-USA). Starting May 2011 above alloys are certified according to NSF/ANSI Standard 372 – 2010 Drinking Water System Components - Lead Content instead of the previous/ANSI Standard 61, including Annex G.

- 14/3/2011 – Environmental certification UNI EN ISO 14001/2004

We are proud to inform that the company Trafilerie Carlo Gnutti obtained the Certification of the Environmental Management System according to the International Standard UNI EN ISO 14001/2004 for our facilities in Chiari, Via S,Bernardino 23/a and Via Silvio Pellico 38. Such Certification has been issued by the Italian Institution RINA, accredited Sincert and concerns all the environmental aspects in both facilities.

- 14/3/2011 – Regulation REACh (CE) n.1907/2006

The regulation REACh (CE) n. 1907/2006, that concerns the Registration, Evaluation, and Authorization of the Chemical substances, entered in force officially on June 1st, 2008. In accordance to the dispositions of REACh, the manufacturer or the importer from Extra-EU countries of a substance, on its own or in preparations, for more than one ton per year has the obligation to register such substance at the EChA (European Chemical Agency), with different procedures and timing depending on the produced/imported quantity and on its danger. After the necessary foreword we want to declare that we are aware of the obligations arising from the REACh Regulation and that we are proactive in supporting the scope of this Regulation, keeping our customers and suppliers duly informed. We point out that we do not manufacture or import Chemical Substances, but it may happen that we purchase some of them; in this case the registration as per REACh instructions must be done by our suppliers. In order to respect the law we have duly verified that our suppliers have already registered such substances. Furthermore we declare that our products do not contain, above the limits defined in the same Regulation, any substance listed in the Candidate List of the up-to-dated SVHC published in the EChA website. In addition, our products do not contain any Organic Substances as per annex XIV (substances subject to authorization) included in the Regulation 143/2011. Please do not hesitate to contact us in case of doubts. The contact person is Ing. Marcello Capuzzi, tell +39 03070061, fax +39 0307001670, e-mail gestione@gnuttichiari.it

Trafilerie Carlo Gnutti is proud to announce NSF/ANSI 61 (NSF 61) – Drinking Water System Components – Health Effects NSF International approval for the alloys named CW509L 02 ( OT60-USA ), CW510L ( OT57-USA ) e CW511L ( ADZ-USA ). The certification to American National Standard for public water supply products is necessary to respect California Waterworks Standards The certification to NSF/ANSI Standard 61 , including Annex G demonstrates compliance with California’s Health and Safety Code Section 116875 (commonly known as AB 1953).

- Binary brass alloys for parts in contact with drinking water

The evolution of legal and technical standards concerning materials in contact with drinking water will impose more restrictive specifications for the content and the release of Lead (Pb) in copper alloys. In order to meet already existing requirements and to anticipate the evolution of the European ones, we are proud to introduce, with the enclosed brochure, the new family of Binary alloys. Binary means just Copper and Zinc, and thanks to this “simplicity” the new alloys offer many positive features: • No content of Silicon, Bismuth, Selenium or other rare elements, so turnings can be mixed with the normal leaded scrap without downgrading the whole quality • Fair to good machinability • Mechanical properties similar to the normal leaded brass • Available DRZ version On top of the above mentioned features, last but not least, we can mention that Binary alloys look to be the less expensive alternative in the field of no-lead alloys. We are then confident that Binary alloy will soon become the first choice to consider for pieces in contact with drinking water.
