European bodies update coil coating

standards

CEN, the European Committee for Standardization, hasEurope-wide membership, work procedures and role. Thisorganization and its associated standards body, ECISS, theEuropean Committee for Iron and Steel Standardization, areintroduced, as is its growing cooperation with ISO, theInternational Organization for Standardization. Over the pastmonths a three-part standard on coil coated steel productshas been published. A number of standardized test methodsfor coil coated metals are also available.Bernd Meuthen.Against the background of recent activities, it seemsappropriate to refer to the relevant international

standardization institutions and committees, and summarizetheir way of working. Standardization of coil coated productsand test methods are also among the key objectives of theEuropean Coil Coating Association (ECCA) of Brussels.

CEN - the European Committee for StandardizationCEN was founded in 1961 by the national standards bodiesin the European Economic Community and European FreeTrade Association (EFTA) countries as an independent legalorganization with its Central Secretariat in Brussels.The principal issue is the European standard (EN) thatexists in three official languages (English, French andGerman). CEN national members are bound to comply withthe CEN Internal Regulations. These stipulate the conditionsfor giving a standard the status of a national standardwithout any alteration or by endorsement within six months

and that any pre-existing national standard in conflict bewithdrawn. German versions are prefixed as in DIN EN,corresponding to BS EN and NF EN. A version in any otherlanguage made by translation under the responsibility of aCEN member into its own language and notified to theManagement Centre (CMC) has the same status as thethree official versions.New work items start with a working document prepared bya Working Group. The working document becomes a draftEuropean Standard (prEN) and, following a customaryadministrative route via the CEN Management Centre, in theend a European Standard (EN). CEN members are granteda six-month enquiry of the drafts and a two-month deadlineof cognisance of the final texts but without any technicalchanges to them. This procedure is completed by theratification by CEN.

CEN membership and relationsNational Members (Figure 1) are the national standardsbodies (NSB) of the enlarged European Union, EFTA andsome Central and Eastern European (CEE) countries. They(1) make up the delegations to the technical committees byfinding expertise in each country; (2) vote for and implementEuropean standards as national standards; (3) provide thesecretariats of the committees; and (4) finance more than 50% of the work. In turn they are largely financed by industry,sales of standards and government grants.CEN presently comprises in all 28 NSB (listed with theiracronyms) compared with only 18 in 1996. There are 25from the EU: Austria (ON), Belgium (IBN/BIN), CzechRepublic (CSNI), Cyprus (CYS), Denmark (DS), Estonia(EVS), Finland (SFS), France (AFNOR), Germany (DIN),

Greece (ELOT), Hungary (MSZT), Ireland (NSAI), Italy(UNI), Latvia (LVS), Lithuania (LST), Luxembourg (SEE),Malta (MSA), The Netherlands (NEN), Poland (PKN),

Portugal (IPQ), Slovakia (SUTN), Slovenia (SIST), Spain(AENOR), Sweden (SIS), and the United Kingdom (BSI). Inaddition, Iceland (IST), Norway (NSF) and Switzerland(SNV) are members from EFTA.

Counsellors, affiliates and partnersCounsellors are the European Commission and the EFTASecretariat. Affiliates are other national standards bodies ofCentral and Eastern Europe, which can in principle becomemembers of the Union or EFTA, and which therefore canbecome full National Members of CEN by meeting certaincriteria.

Present affiliates are Albania (DPS), Bulgaria (SASM),Croatia (DZNM), Romania (ASRO), the former YugoslavRepublic of Macedonia (FYROM), and Turkey (TSE).Partner Standardization Bodies (correspondingorganizations) are Egypt (EOS), Serbia and Montenegro(SZS), South Africa (SABS), and Ukraine (DSSU).

ECISS - the European Committee for Iron and SteelStandardizationSince 1986 ECISS has taken over the standardizationactivities of COCOR, the Coordinating Committee on thenomenclature of iron and steel products, a committeeoriginally set up under the ECSC (European Coal and SteelCommunity). ECISS, a CEN Associated Standards Body.(ASB), is administered by, but independent of, CEN. Internalrules are in accordance with those of CEN. ECISS develops

draft standards for the definition, classification, testing,chemical analysis and technical delivery requirements forthe products of the steel industry which are then submittedto CEN for further launching.The origins of ECISS and its precursor go back to the early1950s and the foundation of ECSC as the very first of theEuropean communities. The process of Europeanintegration began with coal and steel (Treaty of Paris,ratified in 1952). The Euronorms issued since 1953 hadmerely an optional status.

ECISS and CEN functionsFunctions of the two standards bodies are performed byTechnical Committees (TC), which are responsible for theprogramming and planning, monitoring and execution of thetechnical work, and Subcommittees (SC), which are

responsible for a defined portion of the scope of the relevantTC.Working Groups (WG) are appointed by a TC or SC to dealwith a special and limited area of work. They are composedof individual members (experts) from CEN/ECISS membersand organizations.All the CEN national members are entitled to nominatedelegates to ensure a balance of all interested parties.Strategies identified as achieving CEN- and ECISS-definedobjectives may include, among others:- Use of available national, regional or international sourcedocuments (such as ISO standards) on which to baseEuropean Standards;- Where appropriate, cooperation and liaisons with otherCEN committees and international committees;- information that directly demonstrates the possible use and

acceptance of the standards by the affected businesscommunity.

The work programmeThe ECISS work programme is dealt with by 21 TechnicalCommittees. Among others, these include:- TC 13: Flat products for cold working - Qualities,dimensions, tolerances and specific tests (uncoated hot orcold-rolled steels and cold-rolled steel sections); chairman,J. Dawance; secretariat held by D. Jacobs, IBN/BIN;- TC 27: Surface coated flat products - Qualities,dimensions, tolerances and specific tests; chairman, P.Fnders; secretariat held by H.-F. Hach, FES im DIN; and- TC 27/SC 1: Continuously organic coated (coil coated)steel flat products; chairman, B. Meuthen.

European standardization and the role of CENCEN is contributing to the objectives of the EuropeanEconomic Area with technical standards which promote freetrade, the safety of workers and consumers, interoperabilityof systems and technologies, environmental protection,exploitation of research and development programmes, andpublic procurement. The foremost aim is to facilitate theexchange of goods and services through the elimination oftechnical barriers to global trade, thus ensuring theinteroperability and interchangeability of safe and highquality products and systems.The use of standards by industry and the social andeconomic partners is always voluntary; however, Europeanstandards are sometimes related to European legislation(Directives), and conformity to such standards mayconstitute a presumption of conformity to the legalrequirements of the Directives which must be met bymanufacturers before certain products can be traded legallywithin the Single Market. A European standard embodiesthe essential principles of global openness andtransparency, consensus, technical coherence and nationalcommitment.

ISO - International Organization for StandardizationOne cannot report on standardization without mentioningISO, the worldwide federation of national standards bodies,constituted as far back as 1947, with its Central Secretariatin Geneva, Switzerland. Its current membership comprisesnational standards institutes from 148 countries, working inpartnership with international organizations, governmentsand industry, business and consumer representatives.Official languages are English and French. Final DraftInternational Standards (FDIS) become Standards (ISO).Implementation is, however, optional only.

A growing cooperationISO and CEN work closely together according to theirVienna Agreement (1991): Technical cooperation under theVA, where the work is done by CEN following a formalnotification of interest received by CEN from ISO (VA CENlead) or vice versa (VA ISO lead). Parallel synchronizedprocedures are applied in either organization for theapproval processes.The growing cooperation between CEN and ISO may becharacterized by CEN/TC 139 "Paint and varnishes"(secretariat held by DIN) established in 1988 and itscounterpart ISO/TC 35 "Paint and varnishes" established in1947. Over the past years, an increasing number of ISOstandards, particularly on terminology (SC 1) and testmethods (SC 9) have already been transposed into the CENnetwork (as EN ISO). (EN) ISO standards are referred to,whenever applicable.However, the specific work on test methods for coil coatedmetals has since 1995 been the responsibility of CEN/TC139/WG 9 "Coil coated metals - Test methods" (convenors,F. Ferron / H. Hughes) in cooperation with and supported by

ECCA. 25 Parts have already been published (Table 1).

An update on coil coated steel standardizationThe EN 10169 standard for coil coated steel consists ofthree parts: EN 10169-1:2003, Continuously organic coated(coil coated) steel flat products - Part 1: General information(definitions, materials, tolerances, test methods),superseding the 1996 issue; prEN 10169-2:2004, Part 2:Products for building exterior application, replacing ENV10169-2:1999; and EN 10169-3:2003, Part 3: Products forbuilding interior applications.ECISS/TC 27/SC 1 began work in 1992 tasked withupdating the Euronorm EU 169-85 for continuously organiccoated steel flat products. This Euronorm was prepared by aWorking Group established in the late 70s and was the firststandard of its kind. It is common practice for existingstandards to be reviewed about every five years todetermine whether any need exists for some major editorialor technical amendments. The transposition into EN (Part 1since 1996) did not pose any problems.Work was then started on compiling supplements Parts 2and 3, governing building exterior and interior applications,since these are the prime sales markets. WG 2 and WG 3were founded for this purpose, with B. Creton and J.Mnigault, BNS (Bureau de Normalisation de la Sidrurgie),Paris, since renamed BN Acier, acting as convenors.WG 2 (Exterior applications) applied considerable effortsbetween 1992 and 2003 in developing, first of all, apre-standard (ENV 10169-2:1999). This was only recentlytransposed into prEN 10169-2:2004. The final standard isdue to be published in 2005. In the period 1997 to 1999, WG3 (Interior applications) succeeded in drafting the new EN10169-3:2003. In their source English versions, the threestandards together have some 60 pages.

What's in the standardsThe usual contents are: Foreword, Scope, Normativereferences, Terms and definitions, Designation, Informationto be supplied by the purchaser, Substrates and organiccoatings, Requirements, Inspection and testing, Marking,Packing and dispatch, Storage, Disputes, Annex, andBibliography.Regarding "Scope" (Part 1): The standard is not applicableto organic coated tin mill products, electrical steels and steelstrapping. Alongside the updated standards for the steelsubstrates, all three parts now include many of the newparts of the EN 13523 series, Coil coated metals - Testmethods (Table 1). "Terms and definitions" list altogether 45definitions for the coil coating process, coating systems,building applications etc.
