Introduction

Why do you need a certification??

Quality!

The Market ask for it!

Product Safety!

In international markets you need always a certification!

Definitions (1)

Sectors regulated by lawIn Bezug auf Akkreditierung, Zertifizierung und Prüfung gelten als gesetzlich geregelt die Bereiche, in denen durch Rechtsvorschriften Regelungen festgelegt sind. Dazu gehören Akkreditierungen, die im Rahmen von Notifizierungsverfahren durchgeführt werden sowie Akkreditierungen, Zertifizierungen, Prüfungen und mit ähnlichen Begriffen beschriebene Verfahren, die in nicht harmonisierten Rechtsvorschriften enthalten sind.

Sectors non-regulated by lawIn Bezug auf Akkreditierung, Zertifizierung und Prüfung gelten als gesetzlich nicht geregelt die Bereiche, in denen keine Rechtsvorschriften der EU oder nationale Rechtsvorschriften existieren und alle Aktivitäten freiwillig auf Vertragsbasis geregelt werden.

IAFINTERNATIONAL ACCREDITATION FORUM(see www.iaf.nu)

IAF Multilateral Recognition Arrangement (MLA)

The primary objective of conformity assessment is to give its users confidence thatrequirements applicable to products, services, systems, processes and materials have been met.

One purpose of the IAF MLA is to provide users in countries with accreditation bodies, that are IAF MLA members, assurance that equivalent certification / bodies in othercountries operate to the same standard as those in their own country.

Accreditations granted by IAF Multilateral Recognition Arrangement (MLA) accreditationbody members are recognised worldwide based on their equivalent accreditationprogrammes, therefore reducing costs and adding value to industry and consumers.

The number of IAF MLA Signatories at November 2007 is as follows:

• IAF QMS MLA: • Three Regional Accreditation Groups (EA, PAC & IAAC) and 39 Accreditation Bodies

• IAF EMS MLA: • Two Regional Accreditation Groups (EA & PAC) and 36 Accreditation Bodies

• IAF Product MLA: • Two Regional Accreditation Groups (EA & PAC) and 28 Accreditation Bodies

Once an accreditation body is a member of the MLA it is required to recognize the certificates issued bycertification/registration bodies accredited by all other members of the MLA.

You will find the complete list under: www.iaf.nuwww.iaf.nu

National requirements: Germany

Wind turbines will certify according the german building law:Type Approval acc. DIBT

Reports– Loads– Safety Equipments– Rotorblades– Machinery, Nacelle cover– Comissioning

Civil engineering check– Tower– Foundation

Relevant: Type Approval isn‘t the same as Type Certificate!!Only official duties have to carry out the Type Approval! TUV NORD are one of them.

National requirements: Asia (1)

IndiaResponsible for permissions:

C-WET (Center for Wind Energy Technology)Ministry of Non-conventional Energy Sources

Requirements: Guideline TAPS-2000 (ammended 2003)IEC WT01 only in combination with IEC 61400-1, ed.3 (2005) or(momentary) possible: GL-Guideline, DS or NVNExtreme Wind speed acc. IS875 (Part 3)-1987Temperature from - 5°C to 60°C99% humidityMay be EarthquakesMinimum 350 power failures per year have to be calculated in the design

TUV NORD had certified wind turbines for the indian market according theTAPS-2000 Guideline.

P.R.China

IEC WT01 and GL-Guideline will be acceptedThe permit procedure is not clear

TUV NORD is still working in certification of different wind turbines from chinesemanufacturers.


34

National requirements: North America (1)

U.S.A.No problems with the IEC-Certificates

No regulatory permit procedure. Every state has his own procedure.

Towers and Foundations have to fullfil some checks through a local Design Certifying Engineer

Often there are special requirements regarding the environmentalconditions (e.g. low temperature, - 30°C and lower)

Manufacturers from abroad have to check and compare the materials (e.g. steel and concrete)

You have to fullfil the UL-Standards (www.ul.com)

Conclusions (1)

Certification is a requirement for a successfullymarket entry and is relevant for:

CustomersFinancing InstitutsInsurance companiesBuilding permissions

19


37

Conclusions (2)

Only authorities / companies which have the accreditationmay arrange the certification (e.g. TUV NORD)

The IEC-Certification is important for the international markets

Nationals Guidelines will adjust in the near futureBut: There is no real international standard today!

The customer need consulting!

Bigger modifications because of new guidelines:IEC 61400-1, ed. 3 (2005)IEC WT01 (2001) will be substituted throughIEC TS 61400-22 (2007) Committee Draft (CD)
