International standardization for electrical systems

IMAGE 2021-06-10 16:23:50.jpg

The automation process is increasingly being integrated into modern production processes, as well as into the management system of organizations. Nevertheless, the mechanisms used in most organizations, and even more so in manufacturing companies, cannot be sharply adapted without significant losses. That is why all processes occur smoothly. Since the presence of various mechanical systems implies constant control over the implementation of production activities, to facilitate the implementation of each process, special international documents are created, namely international standards. Today we introduce you to some of the key international ISO documents for electrical and mechanical systems.

Small craft - Remote mechanical steering systems (ISO 8848:2020)

EN ISO 8848:2021

Despite the fact that innovative technologies are increasingly being automated and, as a result, human intervention in industrial processes is minimized, today even remote control cannot be completely made independent. That is why, to regulate these processes, technological recommendations are created in the form of international standards, one of which is EN ISO 8848: 2021.

This document specifies design, construction, installation and test requirements for remote mechanical cable steering systems and the output ram interface point to rudders, jet drives, outboard and sterndrive engines for small craft. It is applicable to three distinct classes of steering systems for use on various types of craft:

— standard duty steering systems, for small craft with single and twin installations of outboard engines with a total over 15 kW power, and with rudders, sterndrives, and water-jet drives; — light duty steering systems, for small craft with a single outboard engine of 15 kW to 40 kW power; — mini-jet steering systems, excluding personal watercraft.

NOTE Standard and light duty steering systems are mechanically interchangeable. A standard duty steering system can be used on a craft designed for a light duty system. However, a light duty steering system cannot be used on a craft that requires a standard duty steering system. Mini-jet steering systems are mechanically differentiated from the previously mentioned systems and can only be used on mini-jet craft as defined in this document. This document does not address emergency means for steering the craft.

Since this standard is narrow-profile and is suitable only for specific categories, we recommend that you familiarize yourself in more detail with all its parameters and areas to which it applies for correct use and implementation in the future.

Small craft - Non-fire-resistant fuel hoses (ISO 8469:2021)

EN ISO 8469:2021

Electric modes of transport as well as analogues of gasoline and combustible substances are being actively introduced into the technological areas of human activity, nevertheless, the use of combustible substances has not been canceled, and as a result, this category is one of the most demanded from the point of view of regulating safety issues by international standards. One of the most relevant international standards on this issue is EN ISO 8469: 2021.

This document specifies general requirements and physical tests for non-fire-resistant hoses for conveying petrol or petrol blended with ethanol, and diesel fuel or diesel fuel blended with FAME, designed for a working pressure not exceeding 0,34 MPa for hoses with inner diameter up to and including 10 mm, and 0,25 MPa for hoses up to 63 mm inner diameter in small craft. It applies to hoses for small craft with permanently installed fuel systems.

Specifications for fire-resistant hoses are given in ISO 7840:2021. Specifications for permanently installed fuel systems are given in ISO 10088:2013.

If you are interested in purchasing this document, we strongly recommend that you familiarize yourself with the related standards that are mentioned in the annotation to this document, because they can become a quality addition that will allow you to build a full complex in accordance with the latest requirements and norms of the international market.

Small craft - Electrical systems - Alternating and direct current installations (ISO 13297:2020)

EN ISO 13297:2021

Electrical systems, as well as the introduction of innovative technologies in them, is a rather complex concept and has a number of certain subcategories and specific equipment. It is for each of the categories that separate international standards are created, one of which is EN ISO 13297: 2021.

This document specifies the requirements for the design, construction and installation of the following types of DC and AC electrical systems, installed on small craft either individually or in combination:

extra-low-voltage direct current (DC) electrical systems that operate at nominal potentials of 50 V DC or less;

b) single-phase alternating current (AC) systems that operate at a nominal voltage not exceeding AC 250 V.

This document does not cover the following:

— electrical propulsion systems of direct current less than 1 500 V DC, single-phase alternating current up to 1 000 V AC, and three-phase alternating current up to 1 000 V AC, which are addressed by ISO 16315;

— any conductor that is part of an outboard engine assembly and that does not extend beyond the outboard engine manufacturers supplied cowling;

— three-phase AC installations that operate at a nominal voltage not exceeding 500 V AC, which are addressed by IEC 60092-507.

Amendments about which areas are not regulated by this standard make it possible to understand which equipment used in production can be regulated in accordance with this document, and which not.

Small craft - Waste systems - Part 2: Sewage treatment systems (ISO 8099-2:2020)

EN ISO 8099-2:2021

Despite the fact that most international standards are primarily associated with more global companies, corporations and international activities, they are also created for small and medium-sized businesses, describing each separate category and specific type of equipment. One such international standard is EN ISO 8099-2: 2021.

This document specifies requirements for the design, construction and installation of sewage treatment systems on small craft. It does not address waste retention systems, nor accidental discharge prevention of pollutants (e.g. oil, fuel) overboard.

First of all, this international standard can be perceived as global for a certain type of activity. However, it should be noted that it is adapted to the European Union market and excludes some points that are required for a more global scale.

Metallic tube connections for fluid power and general use - Test methods for hydraulic fluid power connections (ISO 19879:2021)

EN ISO 19879:2021

The test methods used for metal structures and products are one of the most critical stages, because the wrong approach in this particular category of activity can entail significant negative consequences in the financial aspect. That is why one should clearly adhere to the recommendations specified in such international documents as EN ISO 19879: 2021.

This document specifies uniform methods for the testing and performance evaluation of metallic tube connections, stud ends for ports and flange connections for use in hydraulic fluid power applications. This document does not apply to the testing of hydraulic quick-action couplings, which is covered by ISO 18869.

Tests outlined in this document are independent of each other and document the method to follow for each test. See the appropriate component International Standard for indications of which tests to conduct and for performance criteria.

For qualification of the connector, the minimum number of samples specified in this document is tested, unless otherwise specified in the relevant connector standard or as agreed upon by the manufacturer and the user.

To build a certain system, it is necessary not only to have qualified employees, but also to have an appropriate scientific and technological base, which will allow you to create an organization with clear and well-established interaction between departments, and will also allow you to get the final high-quality result in the form of a finished product or service in demand.

New ways for increasing the productivity of results

Electrical mechanical systems are one of the most commonly regulated by international standards. If in the previous stages of your activity you did not think about acquiring international standards, this stage can become a new level of development for your organization, moreover, you can make sure in a practical way that the introduction of this particular type of documents allows you to minimize both physical and financial risks, bringing your organization to new qualitative levels of development. If in this list of standards you have not found a suitable one specifically for your activity, but related in a category, you can go to our website and familiarize yourself with all the available standards. After all, it is there that you can find the document that will become the beginning of a new way of developing your business.
