Maritime navigation and radiocommunication equipment and systems Digital interfaces Part 402: Multiple talkers and multiple listeners Ship systems interconnection Documentation and test requirements (Edition 1.0)
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). 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. 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). 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.
