26、 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. T

27、his 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 c

28、ollectively 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 onboa

29、rd 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 app

30、ropriate 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 ne

31、twork 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 relia

32、ble 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

33、 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 requirement

34、s of any other standards for system or equipment functionality. EN 61162-402:2005 6 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 oper

35、ating 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

36、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 procedu

37、res and test tools themselves. 2 Normative references The following referenced documents are indispensable for the application of this document.

44、ng 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 func

45、tional 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 sof

46、tware 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

47、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

48、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

49、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.
