Fibre cables international standards
The pace of development of innovations is increasing every day. Since in the context of global processes, the exchange of technologies between countries very often occurs, it is necessary to understand that the inconsistency of the level of development between some states can cause certain problems when creating a single successfully functioning system. That is why, with the accelerated development of technology, more and more international documents are being created. Some of the institutions that regulate these issues are ISO, CEN, IEC organizations. These organizations create international standards that create conditions for the maximum harmonious development of technology exchange processes as well as their operation, implementation, production and sales at the international level. Today we introduce you to the key international standards in the process equipment industry and related devices.
Optical fibre cables - Part 1-2: Generic specification - Basic optical cable test procedures - General guidance
EN IEC 60794-1-2:2021
A large number of technologies require an appropriate number of regulatory legal acts that regulate their implementation in production processes, and also describe all the specifics of their use. One of such international standards describing the features of operation and cables as well as the materials from which it is made is EN IEC 60794-1-2: 2021.
IEC 60794-1-2:2021 is available as IEC 60794-1-2:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60794-1-2:2021 applies to optical fibre cables for use with telecommunications equipment and devices employing similar techniques, and to cables having a combination of both optical fibres and electrical conductors. An objective of this document is to define general requirements and methodology guidance applicable to all of the cable test methods of IEC 60794-1 (all parts). A second objective of this document is to provide the end user with an overview of the different test methods contained in the different parts of the IEC 60794-1 series. This fifth edition cancels and replaces the fourth edition published in 2017. This edition constitutes a technical revision. This edition includes the following significant technical change with respect to the previous edition: - addition of cross-reference tables listing the new test method numbers and the previous test method numbers.
This standard has several parts. Each part is responsible for a certain type of the above-mentioned device, which is why we recommend that you study all the technical parameters in detail by clicking on the link attached above.

Optical fibre cables - Part 1-211: Generic specification - Basic optical cable test procedures - Environmental test methods - Sheath shrinkage, method F11
As mentioned earlier, each document has a certain number of parts, each part has a set of technical characteristics, which can sometimes be partially similar, but at the same time have certain amendments. The next part to the previous cable management standard is IEC 60794-1-211: 2021.
It defines test procedures to measure the shrinkage of the sheath due to thermal exposure of cables. A first test method, F11A, is included for cables where the fibre or buffered fibre and the sheath of the cable are intended to be fully terminated into a connector at one or both cable ends. A second test method, F11B, is included in this document for sheath shrinkage testing for general purpose. See IEC 60794-1-2 for a reference guide to test methods of all types and for general requirements.

Optical fibre cables - Part 3-12: Outdoor cables - Detailed specification for duct and directly buried optical telecommunication cables for use in premises cabling
International standards regulating technologies are created not only for professional use, but also for technologies used in everyday life. One such international standard is IEC 60794-3-12: 2021.
IEC 60794-3-12:2021 is available as IEC 60794-3-12:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.
IEC 60794-3-12:2021 is a detailed specification for duct and directly buried optical telecommunication cables for use in premises cabling to ensure compatibility with ISO/IEC 11801-1. This document's requirements ensure that the ISO/IEC 11801-1 models work for generic cabling and system performances. Values in this document support these models. The requirements of the family specification IEC 60794-3-10 are applicable to cables covered by this document. Particular requirements detailed in Clause 5 either define a specific option relative to the requirements of IEC 60794-3-10 or define additional requirements. This third edition cancels and replaces the second edition published in 2012. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
addition of references to ISO/IEC 11801-1;
removal of references to ISO/IEC 24702;
incorporation of the OM5 cabled fibre performance category;
incorporation of the OS1a cabled fibre performance category;
cabled fibre performance categories OM1, OM2 and OS1 are no longer normative, and are retained for information.
Since this document can be used both in the professional production and operation of technologies, and in everyday life, we recommend that you pay attention to it if the mentioned technologies are applied in your field of activity, especially at a professional level.
Any statistical data is usually obtained by analyzing the results of an empirical approach to research. Measuring in the process of using technology is one of the subjects for regulation by international standards. One of the documents regulating measurement processes is IEC 60793-1-34: 2021.
This standard is available as IEC 60793-1-34:2021 RLV which contains the International Standard and its Redline version, showing all changes of the technical content compared to the previous edition.IEC 60793-1-34:2021 establishes uniform requirements for the mechanical characteristic: fibre curl or latent curvature in uncoated optical fibres, i.e. a specified length of the fibre has been stripped from coating. Fibre curl has been identified as an important parameter for minimizing the splice loss of optical fibres when using passive alignment fusion splicers or active alignment mass fusion splicers.Two methods are recognized for the measurement of fibre curl, in uncoated optical fibres:
method A: side view microscopy;
method B: laser beam scattering.
Both methods measure the radius of curvature of an uncoated fibre by determining the amount of deflection that occurs as an unsupported fibre end is rotated about the fibre's axis. Method A uses visual or digital video methods to determine the deflection of the fibre while method B uses a line sensor to measure the maximum deflection of one laser beam relative to a reference laser beam. By measuring the deflection behaviour of the fibre as it is rotated about its axis and understanding the geometry of the measuring device, the fibre's radius of curvature can be calculated from simple circular models, the derivation of which are given in Annex C. Both methods are applicable to type B optical fibres as described in IEC 60793 (all parts). Method A is the reference test method, used to resolve disputes. This third edition cancels and replaces the second edition published in 2006. This edition constitutes a technical revision. This edition includes the following significant technical changes with respect to the previous edition:
modification of several derivation equations for laser scattering;
change of angular increment from 10° to 30° to 10° to 45°;
change of Annex B from informative to normative.
This standard, due to its specificity, has a certain number of technological amendments and clarifications. That is why we recommend that you familiarize yourself with them in detail, because a detailed description will make it possible to avoid the mistakes of acquiring the wrong standard.
Since wires are made from different materials, depending on where they are used, therefore, an appropriate international standard is created for each of the types of materials. One of the standards governing the use of steel cords is EN 12385-3: 2020.
This document specifies the type of information for use and maintenance of steel wire ropes to be provided by the rope manufacturer or to be included in the manufacturer’s handbook that accompanies a machine, piece of equipment or installation of which the steel wire rope forms a part.
The particular hazards covered by this document are identified in Clause 4. For steel wire ropes conforming to Parts 8 and 9 used on cableway installations designed to carry persons, additional information for use and maintenance is given in EN 12927.
For steel wire rope slings, specific information on use and maintenance is given in EN 13414-2. This document is not applicable to steel wire ropes manufactured before the date of publication of this document by CEN.
International documents can be applied both globally and nationally. If your company operates within the framework of one state, we still recommend in any case to have international documents available that will allow you to further expand the scale of your activities.
International standards as a key indicator of high competitiveness level
In any industry of the modern world, an increasing number of companies are being created that provide each other, and whole separate subcategories are being created in existing industries. With an increase in the number of organizations and competitors, the demand for high-quality products increases significantly. In order to remain in the leading positions of the market in which your business operates, you need to be sure that each stage of production and implementation of new equipment is established as clearly as possible and in accordance with international norms and rules. That is why if you are worried about the quality of the final products produced at your enterprise, as well as about the safety of both financial and physical resources, we recommend that you have international standards without fail and follow their periodic updates in order to stay up to date with the latest market requirements.
