FOREWORD

1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising

all national electrotechnical committees (IEC National Committees). The object of IEC is to promote international

co-operation on all questions concerning standardization in the electrical and electronic fields. To this end and

in addition to other activities, IEC publishes International Standards, Technical Specifications, Technical Reports,

Publicly Available Specifications (PAS) and Guides (hereafter referred to as "IEC Publication(s)"). Their

preparation is entrusted to technical committees; any IEC National Committee interested in the subject dealt with

may participate in this preparatory work. International, governmental and non-governmental organizations liaising

with the IEC also participate in this preparation. IEC collaborates closely with the International Organization for

Standardization (ISO) in accordance with conditions determined by agreement between the two organizations.

2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international

consensus of opinion on the relevant subjects since each technical committee has representation from all

interested IEC National Committees.

3) IEC Publications have the form of recommendations for international use and are accepted by IEC National

Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC

Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any

misinterpretation by any end user.

4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications

transparently to the maximum extent possible in their national and regional publications. Any divergence between

any IEC Publication and the corresponding national or regional publication shall be clearly indicated in the latter.

5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity

assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any

services carried out by independent certification bodies.

6) All users should ensure that they have the latest edition of this publication.

7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and

members of its technical committees and IEC National Committees for any personal injury, property damage or

other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and

expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC Publications.

8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is

indispensable for the correct application of this publication.

9) Attention is drawn to the possibility that some of the elements of this IEC Publication may be the subject of patent

rights. IEC shall not be held responsible for identifying any or all such patent rights.

A PAS is an intermediate specification made available to the public and needing a lower level

of consensus than an International Standard to be approved by vote (simple majority).

IEC PAS 63343 has been processed by IEC technical committee 80: Maritime navigation and

radiocommunication equipment and systems.

of which it shall be published as another type of normative document, or shall be withdrawn.

5.1.1 Overview

This part specifies the minimum operational and performance requirements, methods of testing

and required test results for ASM Mobile station.

It takes into consideration the technical characteristics of shipborne AIS equipment, included in

recommendation ITU-R M.1371 and IEC 61993-2 (see 5.1.3.11).

ASM mobile station is intended to be used onboard any marine vessel that may operate globally

or regionally anywhere in the world. The main high-level functions of the ASM mobile station

are:

a) transmit through ASM VHF Data Link (ASM VDL) information which is input to ASM mobile

station by other onboard equipment through Presentation Interface (PI);
---------------------- Page: 11 ----------------------
– 10 – IEC PAS 63343:2021  IEC 2021

b) output all information received from ASM VDL applicable to own station, through PI so that

this information is available to other onboard equipment;
c) handle applicable ASM radio station duties.
In following text, term "Equipment" is used to refer to ASM mobile station.
5.1.2 General requirements

An ASM mobile station shall as a minimum fulfil requirements set in IEC 61193-2, with

exceptions as detailed in this document for interoperability between AIS and ASM transmission

and reception.
5.1.2.1 Marking and identification

Equipment shall be marked as required by IEC 60945:2002, Clause 15. In addition, the

markings shall include:

• details of the power supply from which the equipment is intended to be operated; and,

• if applicable, the date by which batteries need to be replaced.
5.1.2.2 Manuals

Manuals for Equipment shall comply with requirements set in IEC 60945:2002, Clause 14, as

applicable. In addition the manuals shall include:
• the type and details of all external connectors;
• the needed information for correct siting of the antennas;

• description for each alert that may be released by the equipment. The description shall

briefly explain the root causes for each alert, give guidance for users on what implications

the alert has for safe operation of ship and what actions may be necessary to rectify the

alert condition.
5.1.2.3 Quality assurance

The Administration shall require that the manufacturers have a quality control system audited

by a competent authority to ensure continuous compliance with the conditions of conformance

assessment. Alternatively, the Administration may use final product verification procedures

where a competent authority verifies conformance with the certificate of conformance before

the product is installed on board ships.
NOTE The ISO 9000 family standards, as applicable, meets this requirement.
5.1.2.4 Source of UTC

The Equipment shall be provided with a source of UTC, such as GNSS receiver, which is

required for synchronisation purposes.

The internal GNSS receiver shall meet the following requirements of IEC 61108 (all parts):

acquisition, re-acquisition, receiver sensitivity, RF dynamic range, effects of specific interfering

signals, status indications.
