Maritime navigation and radiocommunication equipment and systems - Digital interfaces -- Part 402: Multiple talkers and multiple listeners - Ship systems interconnection - Documentation and test requirements

This standard series, IEC 61162-400 and upwards, specifies a communication protocol for use in integrated ship systems. It also specifies an interface description language for use together with the protocol, a set of rules for the use of this language and a set of standard interfaces described in the language. This part of the standard specifies a minimum set of tests to be done, test results to be achieved and documents that shall be available for all implementations of general protocol software and applications that are compliant with the IEC 61162-4 standard. Although this set of standard documents is collectively referred to as IEC 61162-4, the actual part numbers are in the 400-series (see 1.4 of IEC 61162-400). The tests and documentation requirements do not cover electrical, physical or environmental requirements that may apply to the use of software or computers onboard ships. Such requirements may be covered by IEC 60945 or IEC 60092-504. Other standards may also be applicable. This standard does not necessarily cover all requirements from classification societies or other authorities. It is the responsibility of the user of this standard to ensure that all appropriate regulations are addressed. This standard contains tests to check that an application using the IEC 61162-4 protocol adheres to its advertised interface specification. These tests cannot guarantee the correct functionality of that application beyond the possibility of connecting it to the network and with a limited degree of accuracy in the messages transferred. This standard does not cover the system in which the IEC 61162-4 communication standard is used. Additional requirements will normally apply to the total system configuration. Fundamental requirements relating to ensuring reliable and timely transfer of data across data communication links are included in other standards associated with the integration of equipment such as IEC 60092-504 and IEC 61209. This standard does not contain tests to verify compliance with these requirements. In addition, specific equipment related standards may also contain requirements for correctness and timeliness of data transmissions. Neither does this standard contain any tests to verify such requirements. Thus, results from tests carried out in accordance with this standard cannot be used to demonstrate compliance with the requirements of any other standards for system or equipment functionality. The test plan only specifies general tests of the protocols and a limited set of other general properties (black box tests). The test procedures will not generally cover tests of operating systems, communication libraries or other software components that are used to implement the standard. Neither does this standard specify any tests related to the way the system is implemented (white or glass box testing). The test procedures are general in nature and do not generally specify detailed test programs and procedures. The procedures specify a minimum set of functional aspects that need to be tested, with, in some cases, a minimum required set of excitations and corresponding required responses. The testers must develop the detailed procedures and test tools themselves.

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 provides no marking procedure to indicate its approval and cannot be rendered responsible for any
equipment declared to be in conformity with an IEC Publication.
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.
IEC 61162-402 has been prepared by Technical Committee 80: Maritime navigation and
radiocommunication equipment and systems.

1 Scope
1.1 General
This standard series, IEC 61162-400 and upwards, specifies a communication protocol for
use in integrated ship systems. It also specifies an interface description language for use
together with the protocol, a set of rules for the use of this language and a set of standard
interfaces described in the language.
This part of the standard specifies a minimum set of tests to be done, test results to be
achieved and documents that shall be available for all implementations of general protocol
software and applications that are compliant with the IEC 61162-4 standard. Although this set
of standard documents is collectively referred to as IEC 61162-4, the actual part numbers are
in the 400-series (see 1.4 of IEC 61162-400).
1.2 Limitations in scope
The tests and documentation requirements do not cover electrical, physical or environmental
requirements that may apply to the use of software or computers onboard ships. Such
requirements may be covered by IEC 60945 or IEC 60092-504. Other standards may also be
applicable.
This standard does not necessarily cover all requirements from classification societies or
other authorities. It is the responsibility of the user of this standard to ensure that all
appropriate regulations are addressed.
This standard contains tests to check that an application using the IEC 61162-4 protocol
adheres to its advertised interface specification. These tests cannot guarantee the correct
functionality of that application beyond the possibility of connecting it to the network and with
a limited degree of accuracy in the messages transferred.
This standard does not cover the system in which the IEC 61162-4 communication standard is
used. Additional requirements will normally apply to the total system configuration.
Fundamental requirements relating to ensuring reliable and timely transfer of data across data
communication links are included in other standards associated with the integration of
equipment such as IEC 60092-504 and IEC 61209. This standard does not contain tests to
verify compliance with these requirements. In addition, specific equipment related standards
may also contain requirements for correctness and timeliness of data transmissions. Neither
does this standard contain any tests to verify such requirements. Thus, results from tests
carried out in accordance with this standard cannot be used to demonstrate compliance with
the requirements of any other standards for system or equipment functionality.

1.3 Limitations in test coverage
The test plan only specifies general tests of the protocols and a limited set of other general
properties (black box tests). The test procedures will not generally cover tests of operating
systems, communication libraries or other software components that are used to implement
the standard. Neither does this standard specify any tests related to the way the system is
implemented (white or glass box testing).
1.4 Limitations in degree of detail
The test procedures are general in nature and do not generally specify detailed test programs
and procedures. The procedures specify a minimum set of functional aspects that need to be
tested, with, in some cases, a minimum required set of excitations and corresponding
required responses. The testers must develop the detailed procedures and test tools
themselves.

3 Definitions
For the purposes of this document, the following definitions apply.
3.1
black-box testing
testing that ignores the internal workings and internal structure of a component and focuses
on the responses generated as a result of controlled stimuli and execution conditions.
Typically used to evaluate the compliance of a component with specified functional
requirements. See also white-box testing
3.2
defect
latent faults in a component ("bug" in software), that either represent or can cause an error
and by that a failure
3.3
error
that part of the system state that is liable to lead to a failure (IEC 61508-4) IEC 61508-4 does
not classify a software defect as an error, but as a fault. In this standard, the term defect will
be used to mean also software defects. The term fault will not be used.
3.4
fault
see error and defect
3.5
failure
occurs when a delivered service deviates from the intended service. It is the effect of an error
on the service (IEC 61508-4)
3.6
memory leak
situation where a program is not able to reclaim dynamically allocated memory that should be
released as a result of the removal of an internal object. It typically occurs during sequences
of connect and disconnect
3.7
safety integrity level
discrete level (one out of a possible four) where safety integrity level 4 has the highest level
of safety integrity and safety integrity level 1 has the lowest. Safety integrity is the probability
of a safety-related system satisfactorily performing the required safety functions under all the
stated conditions within a stated period of time (see IEC 61508-4).
3.8
white-box testing
testing that uses knowledge of the internal structure and internal workings of a component to
exercise, for example selected internal execution paths or sub-component interactions in the
component. See also black-box testing.

4 Overview and basic principles
4.1 Introduction
This part of IEC 61162 covers test and documentation requirements. Proper testing, based on
a test plan, and the availability of documentation are factors that are important in ensuring the
correctness of a protocol or application software module. This document specifies general
requirements to testing and documentation for both protocol and application modules. This
document only specifies the tests that have to be made and the required test results. It does
not specify the tools or mechanisms that are used to perform the test. This is the
responsibility of the tester.
Documentation requirements are more specific and define the minimum requirements for
documentation that follows protocol or application modules. The user should take care to
supplement the minimum requirements with whatever extra documentation that it is felt to be
necessary to use the module in question. Of particular importance is software documentation
in the case where there is the possibility to modify the module.
Annexes summarise the test requirements in a form that can be used as a test log.
4.2 Purpose of this standard
This standard shall help to ensure that important aspects of an implementation of IEC 61162-
4 basic software does what
