FOREWORD DET NORSKE VERITAS (DNV) is an autonomous and independent foundation with the objectives of safeguarding life, property and the environment, at sea and onshore. DNV undertakes classification, certification, and other verification and consultancy services relating to quality of ships, offshore units and installations, and onshore industries worldwide, and carries out research in relation to these functions. Standards for Certification Standards for Certification (previously Certification Notes) are publications that contain principles, acceptance criteria and practical information related to the Society's consideration of objects, personnel, organisations, services and operations. Standards for Certification also apply as the basis for the issue of certificates and/or declarations that may not necessarily be related to classification. All publications may be downloaded from the Society s Web site http://webshop.dnv.com/global/. The Society reserves the exclusive right to interpret, decide equivalence or make exemptions to this Standard for Certification. This issue supersedes Approval Programme 6-800.00-1 of December 1995. Main Changes The technical requirements are moved to appendices. Technical requirements are updated in accordance with applicable IEC standards or other relevant rules.

Standard for Certification - No. 2.9, April 2010 Type Approval Programme No. 6-800 Page 4 1. DNV TYPE APPROVAL 1.1 Scope This type approval programme gives the requirements on which Det Norske Veritas bases its type approval of products or systems specified in appendix A. In general the conditions outlined in this programme and in the Standard for Certification No. 1.2 Type Approval shall be fulfilled before the type approval certificate is issued. 1.2 Documents to be submitted Application for type approval (form no. 90.01a) is to be submitted. Further documents and number of copies to be submitted are specified in the relevant programmes listed in Appendix A. 2. Design Requirements The product or system is to comply with the rules and regulations as specified in the relevant programmes listed in Appendix A. 3. Elements of Type Approval 3.1 Procedure Type approval procedure consists of the following elements: Initial Survey Design Assessment Type Testing Issuance of Type Approval certificate. 3.2 Initial Survey An initial survey will normally have to be carried out in order to confirm that the manufacturer has a production line and quality control for consistent production of the products for which type approval is requested. The initial survey at the manufacturer may be omitted if products are frequently certified by DNV, periodical audits are carried out or if the manufacturer is certified to ISO 9001 by an accredited body. In those cases the product is manufactured at other companies/ locations than the designer of the product, the initial survey has to be carried out at both designer and manufacturer. A report will be made after the initial survey, and a copy of the report shall be part of the type approval documentation. 3.3 Design Assessment The design assessment is to assess that the design of the product conforms to the requirements specified in 2. Design Requirements above. 3.4 Type Testing (TT) The main objective of the testing is to verify the ability of a material, product or system to meet specified requirements which cannot be verified by analyses and calculations with reasonable reliability. The tests referred to in the documents in 2. Design requirements shall be carried out initially. The type testing can be carried out at the manufacturer's premises when he has suitable facilities available to undertake the testing as required. The testing shall be carried out and witnessed by a DNV surveyor as required and described in the DNV Rules or in the relevant programmes listed in appendix A. A type testing programme shall be worked out by the manufacturer, sent to DNV and agreed upon prior to the commencement of the testing. The test programme shall among others include information on which tests that shall be carried out in the presence of the DNV surveyor. Further, the test programme shall define the acceptance criteria for the testing. Type testing may be carried out by laboratories recognized for the kind of type testing that is required for the different products according to the DNV Rules or in the relevant programmes listed in appendix A. DNV may base its acceptance on the test reports issued by the recognized laboratory confirming compliance with the requirements. 3.5 Recognition of Test laboratory Testing in accordance with the regulations and standards required by the DNV type approval programmes as stated in Appendix A will be accepted when carried out either: 1) at an European Laboratory accredited by an EA (European Accreditation) member, or 2) at a non-european laboratory accredited by an organization who has signed an MLA (multilateral agreement) with EA (examples are: HOKLAS/Hong Kong and NATA/ Australia), or 3) at a laboratory having the quality system approved by DNV based on ISO/IEC/EN 17025. A Statement of Recognition shall be issued, or 4) at a laboratory recognized/certified by an IMO Member State's Marine Administration 5) at a non-recognized/certified laboratory when testing is witnessed by a DNV Surveyor. For detailed test requirements see relevant programmes listed in Appendix A. 3.6 Product Marking The product or packing is to be marked with the name of the manufacturer, type designation and technical rating, as specified in Appendix A. The marking should be carried out in such a manner that it is visible, legible and last throughout the anticipated life of the equipment, and traceable to the type approval certificate. 3.7 Issuance of type approval certificate The type approval certificate will be issued to the applicant in question when compliance with the requirements for the design is confirmed. The type approval certificate will be given a validity of 4 years. 3.8 Retention of Type Approval The objective of the retention survey is to verify that the conditions for the type approval are not altered since the type approval certificate was issued. The scope of the retention survey will normally include: verification of the manufacturer's production line and quality control review of the TA documentation and that this is still used as basis for the production review of possible changes to the design, the material and the performance verification of the product marking. A report is to be made and submitted to the client after a certificate retention survey has been carried out. Survey Report Form 90.02a shall be used. 3.9 Renewal of Type Approval Certificate A reminder letter will be sent to the certificate holder at least 3 months prior to the expiry of the certificate by the local DNV station. The certificate holder may then apply to the local DNV station for renewal of the certificate. DET NORSKE VERITAS

Upon receipt of the request for renewal, the local DNV station will arrange with the certificate retention survey as stated in 3.8 above. The certificate retention survey report will constitute the basis for renewal of the type approval certificate. DET NORSKE VERITAS
