(c) The accuracy of all calculations performed by Inland ECDIS shall be independent of the characteristics of the output device and shall be consistent with the SENC accuracy.

(d) Bearings and distances drawn on the display or those measured between features already drawn on the display shall have accuracy no less than that afforded by the resolution of the display.

5. OPERATION

5.1. Information mode

(a) Information mode shall be used for information only and not for navigation.

(b) In information mode all kinds of chart orientation, rotation, zooming and panning are allowed. However, it is recommended to use the same fixed ranges as in the navigation mode and the chart orientation whether: — to north, or — to the fairway axis at the actual position, or — to the actual vessels heading.

(c) It shall be possible to scroll the chart manually on the screen with the fairway axis in line with the vertical screen axis.

(d) Inland ECDIS may be connected to a positioning sensor to scroll the chart picture automatically and to display the section of chart matching the actual surrounding, namely in the operator-selected range.

(e) Information regarding the position and orientation of other vessels, gathered by communication links like AIS, shall be only displayed if they are up-to-date (nearly real-time) and accurate. If the heading of other vessels is not available, the position and the orientation of those other vessels shall not be presented by: — a directed triangle, or — a true outline (to scale). In this case the usage of a generic symbol is recommended. The following time out values are recommended (from IEC 62388):



Category of vessel Nominal reporting interval Maximum time out value Nominal reporting interval Maximum time out value class A class A class B class B Vessel at anchor or moored and not moving faster than 3 knots (class B not moving faster than 2 knots) 3 min 18 min 3 min 18 min Vessel at anchor or moored and moving at more than 3 knots 10 s 60 s 3 min 18 min Vessel operating in SOLAS mode, moving 0 to 14 knots 10 s 60 s 30 s 180 s Vessel operating in SOLAS mode, moving 0 to 14 knots and changing course 3 1/3 s 60 s 30 s 180 s Vessel operating in SOLAS mode, moving 14 to 23 knots 6 s 36 s 30 s 180 s Vessel operating in SOLAS mode, moving 14 to 23 knots and changing course 2 s 36 s 30 s 180 s Vessel operating in SOLAS mode, moving faster than 23 knots 2 s 30 s 30 s 180 s Vessel operating in SOLAS mode, moving faster than 23 knots and changing course 2 s 30 s 30 s 180 s Vessel operating in inland waterway mode 2 – 10 s 60 s — — The AIS targets should be marked as outdated if the position information of moving vessels is older than 30 seconds. Information on the intention (blue sign) or the number of blue cones of other vessels, the status of signals, weather warnings (from Meteoalarm: www.meteoalarm.eu) and the water level received via Inland AIS may be displayed. The information on the intention (blue sign) shall only be displayed on the right side of the symbol, if the heading of the vessel is available. If no heading information is available the information shall only be displayed in a direction independent form. The following table is providing an example for the display:



Visualisation of Blue Sign status 0 to 2 and dangerous goods Blue sign Not connected or not available Not Set Set Blue cones no 1 to 3 no 1 to 3 no 1 to 3 Heading No Symbol Yes Symbol True shape

(f) Information regarding AIS base stations, AIS Aids to Navigation (ATON) and AIS Search and Rescue Transmitters (SART) may be displayed, if the symbols can be distinguished from other symbols (e.g. symbols 2.10 and 2.11 of IEC 62288 Ed. 2, Table A.2).

(g) Information received by an AIS device and required by local police regulations shall be displayed.

(h) It shall be possible to display all information transmitted by an AIS on user request.

5.2. Navigation mode

(a) In navigation mode, the Inland ECDIS display shall be integrated with the own vessel's radar information. The radar information shall be clearly distinguishable from the SENC information.

(b) The integrated display shall be in accordance with the requirements for radar on inland waterways as specified in Chapter 4.14 of Section 4 of this Annex.

(c) The chart and the radar image shall match in size, position and orientation within the limits as specified in Chapters 3.4 and 8.3.2 of Section 4 of this Annex.

(d) The integrated display shall only be presented in the head-up orientation. Other orientations are permitted in systems with an additional maritime ECDIS type approval. If such a system is used in true motion and/or north-up mode on European inland waterways, it is considered to be working in information mode.

(e) It shall be possible for the operator to adjust the off-set values between the positions of the position sensor and the radar antenna of the vessel so that the SENC display matches the radar image.

(f) It shall be possible to temporarily remove either the ECDIS or the radar information by a single operator action.

(g) The vessel's position shall be derived from a continuous positioning system, the accuracy of which is consistent with the requirements of safe navigation.

(h) Navigation mode shall provide an indication when the input from the position-fixing system is lost. Navigation mode shall also repeat, but only as an indication, any alarm or indication passed to it from a position fixing system.

(i) The positioning system and the SENC shall be based on the same geodetic datum.

(j) In navigation mode, the data referred to in Chapter 3.1, point (c), first to seventh indent of this Section, and the following elements shall always be visible and shall not be obscured by other objects: — Headline line (as required by ETSI EN 302 194-1, see document referred to in Chapter 2, point (f) of Section 1) — Bearing line (as required by ETSI EN 302 194-1, see document referred to in Chapter 2, point (f) of Section 1) — Range rings (as required by ETSI EN 302 194-1, see document referred to in Chapter 2, point (f) of Section 1) — Navigation lines (as required by ETSI EN 302 194-1, see document referred to in Chapter 2, point (f) of Section 1) — P-Lines — Buoys — Inland AIS symbols — Inland AIS labels (if displayed) — AtoN information. The transparency of the radar overlay shall therefore be user defined. It shall be possible to switch Inland AIS labels off either manually or on base of a configured timeout value.

(k) Information regarding the position and orientation of other vessels, gathered by other communication links than the own radar, may be displayed only if they are up-to-date (nearly real-time) and meet the accuracy that is required for the support of tactical and operational navigation. Position information of the own vessel that is received from a repeater station shall not be displayed.

(l) As tracking and tracing information (for example AIS) of other vessels is useful for the planning of the passing, but of no use during passing itself, tracking and tracing (AIS) symbols shall not disturb the radar image during passing and shall be faded out therefore. Preferably the application shall allow the skipper to define the area where the symbol is faded out.

(m) If the heading of other vessels is available, the position and the orientation of those other vessels may be presented by — a directed triangle, or — a true outline (to scale). In all other cases a generic symbol shall be used (an octagon is recommended, a circle shall not be used for applications which are certified according to maritime standards).

(n) Information that another vessel is carrying blue cones or lights may be displayed by a different colour of the vessel symbol. The number of the blue cones/lights shall only be displayed in the pick report.

(o) Information on the intention of another vessel to pass on starboard (blue sign) may only be displayed on the right side of the directed triangle symbol or of the scaled shape if the heading of this vessel is available. If no heading information is available the information shall only be displayed in a direction independent form.

(p) Information regarding the position of AIS base stations, AIS Aids to Navigation (ATON) and AIS Search and Rescue Transmitters (SART) may be displayed, if the symbols can be distinguished from other symbols (e.g. symbols 2.10 and 2.11 of IEC 62288 Ed. 2, Table A.1).

5.3. Operation and control elements

(a) Inland ECDIS shall be designed having regard to ergonomic principles for user-friendly operation.

(b) The Inland ECDIS equipment shall have a minimum of operation and control elements (see Section 4 of this Annex).

(c) Operation and control elements, and indicators for connected sensors, may be integrated in Inland ECDIS.

(d) Standard settings and user-defined settings shall be easily retrievable.

6. CONNECTION WITH OTHER EQUIPMENT

(a) Inland ECDIS shall not affect the performance of any connected equipment adversely. Similarly the connection of optional equipment shall not degrade the performance of Inland ECDIS.

(b) Inland ECDIS shall be capable of generating information to other systems, e.g. for the purpose of electronic reporting.

(c) The relevant requirements of controls and indicators to connected equipment shall be fulfilled.

7. INDICATIONS AND ALARMS

7.1. Built in Test Equipment (BITE)

Inland ECDIS in navigation mode shall be provided with the means for carrying out on-board tests of major functions either automatically or manually. In case of a failure, the module at fault shall be shown.

7.2. Malfunctions

(a) Inland ECDIS in navigation mode shall provide a suitable alarm or indication of system malfunctions (refer to Chapter 9 of Section 4 of this Annex).

(b) Inland ECDIS in information mode shall provide a suitable alarm or indication of missing input from – if connected – GNSS receiver, AIS and heading device.

(c) Inland ECDIS shall provide appropriate alarms or indications of malfunction of the equipment with respect to the displayed information

8. FALL-BACK ARRANGEMENTS

8.1. Insufficient accuracy of the SENC-positioning

3. DATA STRUCTURE

The description of the data structure in Part 3 of S-57 shall apply to the data structure of Inland ENCs and bathymetric Inland ENCs.

4. PRODUCT SPECIFICATIONS FOR INLAND ENCs AND BATHYMETRIC INLAND ENCs

The Product Specifications for Inland ENCs and for bathymetric Inland ENCs enable chart producers to produce a consistent Inland ENC or bathymetric Inland ENC, and manufacturers to use that data efficiently in an Inland ECDIS that satisfies the Performance Standard for Inland ECDIS set out in Section 1.

Data for ENCs shall be made available to all manufacturers of applications. An Inland ENC shall be produced in accordance with the rules laid down in the document referred to in point 2(h) of Section 1 of this Annex and shall be encoded using the following documents referred to therein:

(a) the Inland ENC Feature Catalogue and

(b) the rules described in the Inland ENC Encoding Guide.

A bathymetric Inland ENC shall be produced in accordance with the rules laid down in the document referred to in point 2(j) of Section 1 of this Annex and shall be encoded using:

(d) the rules described in the Inland ENC Encoding Guide referred to in point 2(h) of Section 1 of this Annex

Inland ENCs and bathymetric Inland ENCs approved for navigation mode shall be produced in accordance with the ‘Data Standard’ and the ‘Product Specification’ referred to in this Section.

SECTION 2A

CODES FOR PRODUCERS AND WATERWAYS (IN ADDITION TO IHO–S-62 ENC PRODUCER CODES

Codes for producers of Inland ENCs as well as the registration procedure are those mentioned in the document referred to in point 2(b) of Section 1 of this Annex (‘IHO S-62’).

Administrations or private companies which produce Inland ENCs and which are not mentioned in IHO-S-62 and administrations or private companies which decide to produce Inland ENCs shall register a producer code at the S-100 registry of IHO at http://registry.iho.int

Since a producer code alone is not sufficient to establish whether an Inland ENC is appropriate to be used in navigation mode, the competent authorities referred to in Article 8 of Directive 2005/44/EC shall maintain and provide via their official website an up-to-date list of Inland ENCs approved for navigation mode within their geographical area of responsibility. The list shall include the file name of the ENC cell, the stretch of the inland waterway that is covered, the edition number, the issue date and a list of available update files to the currently valid edition also with their issue dates. The list shall include all Inland ENC for which the cell complies with the requirements as regards the minimum content and is approved for navigation mode.

The notification of competent authorities in accordance with Article 8 of Directive 2005/44/EC shall include information on the geographical area of responsibility and the official website of the competent authorities. Member States shall notify the Commission immediately of any changes.

The following Codes for Waterways shall be used in the file name of IENCs:

SECTION 3

PRESENTATION STANDARD FOR INLAND ECDIS

1. INTRODUCTION

(a) This Presentation Standard for Inland ECDIS describes the technical specifications to be used for the presentation of Inland ECDIS data. The presentation shall take place in such a way that none of the information is lost.

(b) This Presentation Standard is based on the document referred to in point 2(c) of Section 1 (‘S-52’).

(c) This Presentation Standard describes the necessary additions and clarifications to S-52 and the application of S-52 for the purpose of use in Inland ECDIS applications.

(d) The presentation of Inland ECDIS data shall meet the requirements of the Presentation Standard described in Section 3 and the Presentation Library referred to in point 2(i) of Section 1.

(e) Definitions of terms may be found in: — Part 1, clause 5 of IHO-S-57, — the document referred to in point 2(g) of Section 1 of this Annex, — the ‘Glossary for Inland ECDIS’ in Section 5 of this Annex.

2. THE PRESENTATION LIBRARY FOR INLAND ECDIS

S-57 data sets describe the data standard for Inland ENCs, however, they do not contain any information about how the data is going to be presented. The chart presentation is generated online in the Inland ECDIS application. For that purpose, the Inland ECDIS application uses machine-readable symbolisation instructions for each feature, which is drawn on the screen. For the presentation of ENCs the IHO S-52 standard is mandatory. The S-52 standard contains all rules which are necessary for the symbolisation and presentation of ENCs on the screen.

Since the features, attributes and attribute values for ENCs were extended for Inland ENCs and bathymetric Inland ENCs, an extension of the S-52 standard is necessary in order to be able to display also the Inland specific features. All extensions apply to the document referred to in the fourth indent of point 2(c) of Section 1 of this Annex.

2.1. Components of S-52 and Inland ECDIS Presentation Library

2.1.1. The major components of the S-52 presentation library are: — a library of symbols, line styles and fill styles, — a colour coding scheme which includes the IHO colour tables for day, dusk and night time, — a set of symbology command words from which machine readable instructions can be assembled. The result is a symbology instruction, which is processed to symbolise ENC features in turn, — a set of conditional symbology procedures to decide the appropriate symbolisation in cases determined by the mariner's selection (e.g. safety contour) or for complex symbols (e. g. top marks on buoys and beacons), — a set of look-up tables that link feature descriptions from the ENC to the appropriate symbology instructions depending on whether: — the link is straight forward, i.e. a direct relationship between a feature's description and its presentation such as a buoy or a land area. In this case, the look-up table provides the symbology instruction to show a symbol, an area fill, or a line style, — the link is conditional, i.e. depending on circumstances, for example a depth area, whose colour fill depends on the choice of the safety contour. In this case the look-up table refers the decision to a conditional symbology procedure that selects the appropriate symbology instructions later.

2.1.2. Inland ECDIS shall use all S-52 components plus extensions in: — Lookup tables — Symbol library — Conditional symbology procedures. The extensions are described in the document referred to in point 2(i) of Section 1.

2.2. Look-up tables

2.2.1. For each geometry type (point, line, area) there is a separate look-up table. Each entry in a look-up table consists of the following fields: (a) 6-character code of the feature class (acronym); (b) Attribute combination; (c) Symbolisation instructions; (d) Display priority, 0-9 (comparable with drawing layers); (e) Radar code; (f) Display category (Display base, standard, all other); (g) ‘Viewing group’, more refined grouping of features than the display categories. Figure 1 Example entry of a look-up table "LNDMRK","CATLMK17|","SY(TOWERS01)","7","O","OTHER","32250" In this case the feature LNDMRK is shown by the symbol TOWERS01 with priority 7, if the attribute CATLMK equals 17. The feature lies over the radar. The presentation of features in a specific area that are contained in different cells of the same usage follows the entries in the look-up tables.

2.2.2. The Presentation Library provides five look-up tables: — paper chart point symbols, — simplified point symbols, — line symbols, — plain area boundary symbols, — symbolised area boundary symbols.

2.3. Conditional symbology procedures (CS)

CS procedures shall be generated for features of which the symbolisation

— depends on application settings, e.g. safety contour,

— depends on other features, e.g. top marks and their structure,

— is too complex to be defined in a direct look-up table entry.

CS procedures, which shall be modified or implemented in an Inland ECDIS additional to the CS procedures of S-52 are described in the document referred to in point 2(i) of Section 1.

2.4. Colours

Colours used in an ECDIS are defined in an absolute manner, independently from the monitor used (using CIE coordinates). This ensures that ECDIS charts look similar on monitors of different suppliers. CIE values are converted into RGB values by means of colour calibration software which must be used by the manufacturer.

Commercial displays usual in the trade are seen as matching those requirements.

Due to the fact that various light conditions might occur on the bridge of a vessel, it is necessary to offer presentations with different brightness levels. For each level a separate colour table exists.

The represented colour scheme shall be chosen on the basis of ergonomical and physiological factors and the representation of indications in different colours shall not result in mixed colours by superimposing.

2.5. Presentation of notice marks

Notice marks which are located at the river bank are presented in the chart displayed by generic symbols (notmrk01, notmrk02 and notmrk03). This does not apply to the notice marks on bridges.

Additionally, applications are required to be able to display the detailed symbol, which is similar to the real world indication, and the full set of object information of a user-selected notice mark.

Notice marks that are located at bridges, shall be symbolised according to the orientation of the bridge.

Notice marks which specify distances or a velocity shall not be symbolised with the number itself, but only with that symbol which gives the general regulation or information.

SECTION 4

OPERATIONAL AND PERFORMANCE REQUIREMENTS, METHODS OF TESTING AND REQUIRED TEST RESULTS

1. INTRODUCTION

This Section specifies the minimum requirements contained in Section 1 of this Annex and describes the test procedures and the required results concerning the hardware, the software, the functions, the operation, the display and the interfaces to other equipment on board of vessels.

(a) The Inland ECDIS technical specifications distinguish two operating modes: navigation mode and information mode.

(b) Inland ECDIS equipment designed for operating in navigation mode shall fulfil the requirements of this Annex and the standards on navigational radar equipment and rate-of-turn indicators. For Inland ECDIS in navigation mode a type approval is required by competent authorities referred to in point 2(q) of Section 1.

(c) For Inland ECDIS equipment designed for information mode only, the requirements of this Section 4 are to be understood as technical (operational and performance) requirements. The producer has to document the conformity with these technical requirements. A type approval is not required for Inland ECDIS in information mode. The documentation shall be made available to competent authorities and users on request.

2.2. System configurations

2.2.1. System configuration 1: Inland ECDIS equipment, stand-alone-system without connection to radar

In this system configuration only operation in information mode is possible (see Section 4B, Figure 1).

2.2.2. System configuration 2: Inland ECDIS equipment, parallel installation and connection to radar

This system configuration allows operation in information mode as well as in navigation mode (see Section 4B, Figure 2).

2.2.3. System configuration 3: Inland ECDIS equipment, monitor shared with connected radar equipment

In this system configuration, the monitor of the radar equipment is shared with the Inland ECDIS equipment. Prerequisite for this mode are matching graphic parameters for both video signals and a video switch, which allows a fast switchover of the video sources (see Section 4B, Figure 3).

This system configuration allows operation in information mode as well as in navigation mode.

2.2.4. System configuration 4: Radar equipment with integrated Inland ECDIS functionality

This system configuration is a radar installation with integrated Inland ECDIS functionality that can be operated in information mode as well as in navigation mode (see Section 4B, Fig. 4).

3. PERFORMANCE REQUIREMENTS

(b) In information mode the requirements of point 4.1(c) of Section 1 shall be applicable.

3.4.2. Display orientation

(a) A rectangular display may be mounted in landscape or in portrait orientation under the prerequisite that the minimum dimensions set out in Section 3.4.1 are fulfilled.

(b) Because of the limited space available in the typical wheelhouse of an inland vessel and the fact that a vessel usually follows the fairway-axis, the display shall be installed preferably in the portrait orientation.

3.4.3. Display resolution

A display resolution of 5 m in the 1 200 m range is required. This leads to a maximum pixel dimension of 2,5 m × 2,5 m, i.e. about 1 000 pixels at the short edge of the display.

3.4.4. Display colours

The system shall be able to display ergonomically proven colour combinations for day and night.

3.4.5. Display brilliance

The brilliance of the display shall be adjustable to every operational required value. This is especially valid for the lowest value during operation at night.

The information density shall be at least adjustable to the three switch steps: ‘Base’, ‘Standard’ and ‘All Information’. The latter displays all other features in addition to the ‘Standard’ display, individually on demand. All corresponding visible features are defined in the ‘Performance Standard’ and the ‘Presentation Standard’ (incl. the ‘Presentation Library for Inland ECDIS’) (Sections 1 and 3 of this Annex).

4.7. Ranges/Range rings

(a) In navigation mode the following fixed ranges and range rings are prescribed according to the radar regulations:



Range Range rings 500 m 100 m 800 m 200 m 1 200 m 200 m 1 600 m 400 m 2 000 m 400 m 4 000 m 800 m

(b) Smaller and larger ranges with a minimum of four and a maximum of six range rings are permitted.

(c) Inland ECDIS equipment in navigation mode shall have fixed range rings with the intervals set out in points (a) and (b) and at least one variable range marker (VRM).

(d) Switching on/off of fixed and variable range markers shall be independent of each other and their display shall be clearly distinguishable.

(e) The position of the VRM and the corresponding displayed distance shall use the same increments and resolution.

(f) The functions of the VRM and the electronic bearing line (EBL) may additionally be realised by a cursor and by a corresponding numerical display, showing range and bearing of the cursor position.

4.8. Picture brilliance in navigation mode

(a) The brightness of the display shall be adjustable to the operationally necessary value. This applies in particular to operation in darkness.

(b) Chart and radar picture shall have separate brightness controls.

(c) Because of the strongly different environment brightness of bright day and dark night, another control for the basic brightness of the display shall be available additionally to the colour tables in the menu.

4.9. Picture colours

4.10. Pick report

(a) It shall be possible to get all underlying textual and/or graphical information concerning user selections of the features that are displayed in the chart.

(b) This additional textual and/or graphical information shall not hamper the view of the waterway in the navigational chart.

4.11. Measuring features

(a) Measuring features for distances and bearings are required.

(b) Resolution and accuracy shall at least be the same as those of the display, but may not suggest better values than those of the chart data.

4.12. Input and editing of skippers' own chart entries

(a) Inland ECDIS equipment shall allow input, storing, modifying and deletion of additional chart information by the skipper (skippers' own features) in navigation mode as well as in information mode.

(b) These own chart entries shall be distinguishable from the SENC data, and shall not overlay or degrade the radar picture in navigation mode.

4.13. Loading and updating of SENCs

(a) All manual activities concerning loading or updating of charts shall be possible only outside the navigation mode.

(b) Automatic updating shall not downgrade the performance of the navigation display.

(c) A rollback function shall be implemented to allow restoring to the last working combination.

(a) The radar image representation is mandatory for operation in the navigation mode.

(b) The dimensions, resolution and attributes of the radar presentation shall fulfil the relevant radar requirements.

(c) The radar picture shall not be degraded by other contents of the picture (see also point 4.3(c) of this Section).

(d) Provided the functional requirements are fulfilled, overlaying of different information layers is permitted.

(e) The overlay of information regarding the position and orientation of other vessels is only allowed when: — the information is up-to-date (real-time), and — the age of information does not exceed the maximum time out values provided in the first table in point 5.1(e) of Section 1. The symbols shall be marked as outdated, if the age of the information exceeds 30 seconds for moving vessels. The position information of the own vessel shall only be displayed when the position is detected by an on board subsystem and not if the position is received from a repeater station.

(f) The overlaid information derived from tracking and tracing devices regarding the position and orientation of other vessels shall be faded out at a user-definable range. The activation of this feature and the selected range of the restricted area shall be indicated on the display.

(g) Only if the heading of other vessels is available, the position and the orientation of those other vessels may be presented by: — a directed triangle, or — a true outline (to scale). In all other cases a generic symbol shall be used (an octagon is recommended, a circle shall be used for inland applications only).

(h) It shall be possible to switch off the chart and any other information layer and to display only the radar picture by one easily accessible control element or menu area.

(i) If the quality and plausibility monitoring of the Inland ECDIS equipment detect that the chart cannot be oriented and/or positioned with the accuracy required by this Annex, an alarm shall be presented on the display and the chart shall be switched off automatically. If there is no radar signal, the information mode shall be displayed. In both cases a warning or an alarm shall be given. The switching shall always be possible by manual action.

4.15. Inland ECDIS functions with immediate access

(a) The following operational functions require direct access: — RANGE — BRILLIANCE — COLOURS — INFORMATION DENSITY

(b) These functions shall have either own control elements or own menu areas, which are arranged in the highest menu level and are permanently visible.

4.16. Permanently visible function parameters

The following function parameters shall always be visible:

The requirements of Chapters 5.1 to 5.3 are only applicable to navigation mode.

5.1. Static correction of the chart position

(a) The position of the mariner's own vessel shall be presented ‘centred’ or ‘off centred’ on the display in accordance with the radar requirements. The chart position shall match the radar image. Assuming an absolute position's input the permissible static difference between actual radar position and displayed radar centre shall not exceed 1 m.

(b) It shall be possible to correct an offset error (distance between the positions of the position sensor and the radar sensor).

5.2. Static correction of the chart orientation

(a) The difference between the heading line orientation and the vessel's axis shall not be greater than ± 1,0 degree.

(b) Chart and radar image shall have the same orientation. The static directional error between heading line and chart orientation shall be less than ± 0,5 degree.

5.3. Configuration of interfaces

(a) It shall be possible to configure interfaces for connected sensors, actors and signals.

6. HARDWARE TEST AND REQUIRED CERTIFICATES

(a) The test shall consist of a comparison between the Equipment Under Test (EUT) and the requirements of this Annex.

(b) Proved equivalent tests, and proved and documented test results shall be accepted without renewed tests.

(c) The entire Chapter 6 is valid for navigation mode, but the requirements that do not contain a specific reference to navigation mode are also valid for information mode.

6.1. Resistance to environmental conditions in navigation mode

(a) Inland ECDIS equipment, as described in Chapter 2.2.4 of this Section, shall fulfil the requirements of the document referred to in point 2(k) of Section 1 concerning the resistance to environmental conditions (humidity, vibration and temperature; the latter reduced according to Chapter 3.1 of this Section) and concerning electromagnetic compatibility.

(b) The provider or his representative shall submit a relevant conformity declaration of an accredited laboratory.

6.2. Equipment documentation
