Groups A and B are subject to lot-by-lot inspection and groups C and D are subject to periodic inspection. One additional assessment level (other than those specified above) may be added in the detail specification. In this case, it shall be designated by the capital letter X.
5.1.7 Normative reference extensions
Normative reference extensions are used to introduce integrated independent standard specifications or other reference documents into blank detail specifications.
Additional requirements imposed by normative reference extensions are mandatory, unless otherwise specified. Usage is primarily intended to merge associated components to form hybrid devices, or integrated functional application requirements that are dependent on technical expertise other than fibre optics.
Published reference documents produced by ITU, consistent with the scope statements of the relevant IEC specification series, may be used as extensions. Published documents produced by regional standardization bodies, such as TIA, CENELEC, JIS, may be referenced in an informative annex attached to the generic specification.
Some optical fibre splice configurations require special qualification provisions which shall not be imposed universally. These cases encompass individual component design configurations, specialised field tooling, or specific application processes. In these cases, requirements are necessary to ensure repeatable performance or adequate safety, and provide additional guidance for complete product specification. These extensions are mandatory whenever used to prepare, assemble or install an optical fibre splice either for field application usage or preparation of qualification test specimens. The relevant specification shall clarify all stipulations. However, design- and style-dependent extensions shall not be imposed universally.
In the event of conflicting requirements, precedence, in descending order, shall be for “generic” to prevail over “mandatory extension”, which latter prevails over “blank detail”, which latter prevails over “detail”, which latter prevails over “application specific extension”.
Examples of optical connector extensions are given as follows:
— using lEG 61754-4 and lEG 61754-2 to partially define a future IEC 60874 series specification for a duplex type “SC/BFOC/2,5” hybrid connector adapter;
— using IEC 61754-13 and IEC 60869-1-1 to partially define a future IEC 60874 series specification for an integrated type “FC” present attenuated optical connector;
— using lEG 61754-2 and lEG 61073-4 to partially define a future IEC 60874 series specification for a duplex “BFOC/2,5” receptacle incorporating integral mechanical splices.
Other examples of requirements to normative extensions are the following: some commercial or residential building applications may require direct reference to specific safety codes and regulations or incorporate other specific material flammability or toxicity requirements for specialised locations.
Specialised field tooling may require an extension to implement specific ocular safety, electric shock, burn hazard avoidance requirements, or require isolation procedures to prevent potential ignition of combustible gases.
5.2 Documentation
5.2.1 Symbols
Graphical and letter symbols shah, whenever possible, be Taken from IEC 60027 (all parts) and lEG 60617 unless superseded by this document.
5.2.2.2 Blank detail specification
The blank detail specification lists all the parameters and features applicable to power control devices including the type, operating characteristics, housing configurations, test methods and performance requirements. The blank detail specification is applicable to any power control device design and quality assessment requirement. The blank detail specification contains the preferred format for stating the required information in the detail specification.
5.2.2.3 Detail specification
A specific power control device is described by a corresponding detail specification, which is prepared by filling in the blanks of the blank detail specification. Within the constraints imposed by this generic specification, the blank detail specification may be filled in by any national committee of the IEC, thereby defining as an official lEG standard a particular power control device design.IEC 60869-1 pdf download.
