Sec.1. Scope Page 5 1. Scope The type approval programme is for certifying that the equipment under test conforms to the predetermined set of standards. The requirements are based on relevant IMO performance standards and IEC test standards as amended. Underlaying standards may be used when referred to in main standard. The procedure for assessment of conformity of manufactured products (production) is part of the scope for the type approval programme. 2. Conformity Assessment of Design of Product type 2.1 Procedure Type approval procedure consists of the following elements: application for type examination of the product design assessment type testing initial survey certificate retention survey. 2.2 Documents to be submitted for Indicators The following documentation is to be submitted for approval (email or CD) using a common electronic format and protocol (e.g. Acrobat(.pdf) or MS Word format (.doc) and AutoCad): 1) Drawings, schematics and functional descriptions necessary to describe the functionality of all parts of the equipment. 2) Drawings and specification of physical/electrical and logical interfaces including signal format, cabling, converters, I/O cicuits, protective circuitry, data protocol and appropriate configuration of sensors. 3) Information on data handling and built-in data security and monitoring measures if provided. 4) A list of software modules installed comprising function, name, version number and HW residence. 5) Drawings and/or pictures the user interface of display units and user input devices and colour coding of alarms and warnings. 6) Description of power supply, including details on transformers, rectifiers, monitoring circuits, capacity(ies), power consumption, battery(ies). 7) Environmental test program and Performance test program and specification of test site(s). Note: The Manufacturer is to submit the draft test programmes to DNV for approval prior to any environmental and performance type testing commence. A certificate of accreditation for the selected laboratory(ies) is generally a demand (ref. 2.5.3). ---e-n-d---of---n-o-t-e--- 8) Environmental- and Performance type test reports. 9) Description of additional functions incorporated in the equipment, (if any). 10) Operation manual. 11) Installation manual including commissioning specification. 12) Documentation about the Production quality assurance system. 13) Product marking. All the documentation submitted shall be marked in accordance with the manufacturer s QA-system and is to be prepared for easy reference of the various elements asked for. 2.3 Design Requirements for Indicators The indicators is to comply with relevant requirements of the following publications as amended: IMO Resolution A.694(17) (1991): -General requirements for shipborne radio equipment forming part of the GMDSS and for electronic navigational aids. IMO Resolution A.830(19) (1995): -Code on alarms and indicators. IMO Resolution MSC 191(79) Annex (2004): -Performance standards for the presentation of navigationrelated information on shipborne navigational displays.

Publications may be obtained at: www.dnv.com/maritime, Rules & guidance www.imo.org, IMO Publications www.iec.ch, IEC Publications. 2.4 Requirements for Identification of Product with Certificate The manufacturer is to specify type, type number, model, etc., which completely identifies the equipment and its components according to drawings/equipment specification. All optional features are to be listed and those for which type approval is requested are to be marked, either by separate type numbers or by suffixes to the equipment's basic type number. All drawings and descriptions are to be marked with drawing reference number, item name, issue date, etc., which identify the documentation completely. In addition all main software modules installed per hardware unit shall be specified with names and version numbers. The final product shall be provided with visible marking, giving at least the following information: identification of manufacturer equipment type number or model identification serial number safe distance to magnetic compass power consumption and/or supply voltage. 2.5 Elements of Type Approval 2.5.1 Application for type approval The initial stage includes filling in a DNV application form requesting DNV type examination of the product(s). The application form is to be forwarded to the local DNV station together with product documentation and proposed test programs. 2.5.2 Design assessment The second stage involves DNV assessment of the documentation requested in 2.2 is to verify that the design of the product is in conformance with the regulations and standards described in 2.3. 2.5.3 Type testing (TT) When design assessment has been completed by the DNV, including approval of test programmes, the type testing may commence. The type testing comprises: visual inspection performance type testing environmental type testing. The type testing is either to be done in the presence of a DNV surveyor or to be conducted by a recognized laboratory holding a valid accreditation for the relevant tests. Alternatively, the presence of an independent expert from a recognised Authority may be accepted subsequent to approval by DNV Responsible Approval Centre.

Sec.2. Conformity Assessment of Design of Product type Page 7 The type testing shall be reported in accordance with EN 45001 (ISO 17025). It is the manufacturer s responsibility to make sure that the type testing is performed in accordance with approved test programs so being acceptable to DNV. 2.5.3.1 Performance type testing Tests are to be carried out to verify that the performance of the test sample conforms to the applicable requirements. The performance type tests shall as a minimum include those specified in the relevant test standards as amended listed in appendix A. 2.5.3.2 Environmental type testing Tests are to be carried out to verify that the test sample is fit-for-purpose in the marine environment as required by IMO performance standards. The environmental type testing shall be done in accordance with the requirements of IEC 60945. The performance testing to be conducted during relevant environmental tests are to be specified in the test program and sent to DNV for approval. It is the manufacturer s responsibility to ensure that the environmental type testing is performed at an accredited laboratory accepted by DNV. A laboratory accepted by DNV with the presence of a qualified DNV surveyor might be used. 2.5.4 Routine tests (RT) The routine tests, including commissioning tests on board, constitute the final production control and the manufacturers standard RT are to be described in the submitted documentation. These tests are normally to be carried out by the manufacturer or his representative unless otherwise is stated in the type approval certificate 2.5.5 Initial Type Approval Survey An initial TA survey may have to be carried out to confirm that the manufacturer has a production line and quality control for consistent production of the equipment for which TA is requested. 2.5.6 Type approval certificate When the design assessment and type testing are successfully completed a type approval certificate may be issued to the manufacturer verifying the conformity of the design of the product. 2.5.7 Certification retention survey Periodical certificate retention surveys at least every second year are required to maintain the validity of the certificate. The objective is to verify that a consistent production quality control system is implemented and that the product has not been altered with respect to design and functions covered by the type approval. 2.5.8 Renewal of type approval certificate At least three months before the period of validity expires, the certificate holder has to apply for renewal of the certificate. Upon receipt of the request for renewal, DNV will perform a certificate retention survey as stated above. The periodical certificate retention survey report will constitute the basis for renewal of the type approval and the issuance of a new certificate.

Sec.3. Table of Type Tests for Indicators Page 8 3. Table of Type Tests for Indicators The manufacture shall submit a procedure of how to carry out the test described in this table of type tests. Tests are to be carried out at recognized laboratories or alternatively test sites approved by DNV (described in 2.5.3).
