Electrical equipment international standardization

In the process of industrialization, a large variety of technologies have emerged, automatically regulated. When forming the scientific and technological base of the organization, all aspects and parameters were taken into account, which were analyzed on the basis of empirical data. The tendency to build a well-functioning system based on analytical conclusions has remained popular to this day, but there has been a tendency for the globalization of production processes. One of the key issues in this context is the regulation and unification of the existing rules for the production and operation of equipment, not only to simplify the achievement of financial results, but also to increase the safety of the activities carried out. Regulation at the global as well as supranational level occurs thanks to the creation of CEN, ISO standards, with which we will introduce you today.

Machines for underground mines - Safety requirements for hydraulic powered roof supports - Part 1: Support units and general requirements

EN 1804-1:2020

Equipment used in heavy industry not only has a set of subcategories that need to be regulated both locally and globally, but is responsible for the safety of each employee who uses it. That is why it is very important to adhere to the recommendations described in such international standards as EN 1804-1: 2020.

This document stipulates the safety requirements for the use of support units intended by the manufacturer. Examples of support units are: frame supports, chock supports, shield supports, paired frames and push-pull support systems including the components of advancing and anchoring devices which provide support functions. This document excludes fixing elements on the conveyor, coal-winning equipment, power set legs and rams, valves, hydraulic and electro-hydraulic control units, lighting and signalling facilities and other ancillary equipment.

Some components are discussed in other parts of this series of standards. This document applies for support units that are used at ambient temperatures between −10 °C and 60 °C.

This document also applies to support components and support accessories which are provided if the support unit is fitted with stowing equipment. This document identifies and takes account of:

-   the hazards that can possibly be induced through operation of the support units;

-   the hazardous areas and the operating conditions that can cause any type of hazard;

-   the situations that can result in hazards that cause an injury or impair health;

-   dangers that can be caused through mine gas and/or flammable dusts.

This document describes methods for reducing these hazards. Clause 4 contains a list of the hazards discussed.

This document does not specify any additional requirements for:

-   a particularly corrosive environment;

-   risks associated with manufacturing, transport and decommissioning;

-   earthquake.

A complete hydraulic powered roof support consists of the support units (EN 1804-1:2020), legs and support rams (EN 1804-2:2020) and the hydraulic and electro hydraulic controls (EN 1804-3:2020). Each part of this multipart document addresses the safety requirements of the components mentioned in the scopes of the respective parts of this multipart series. This document is not applicable to all support units manufactured before the date of its publication.

The use of the above-mentioned equipment is quite narrow-profile, which is why the standard is created specifically for the methods and possibilities of its use. If the aforementioned technologies are applied in your field of activity, we recommend that you think about purchasing this standard and also check if its previous version was used in your production, to be sure that the activity is carried out in step with the times and the latest trends in international markets.

Food processing machinery - Basic concepts - Part 2: Hygiene and cleanability requirements

EN 1672-2:2020

Hygiene issues have become some of the most popular and frequently discussed in the last two years. Since the issue of human health has undergone strict regulation both by most governments and by standardization institutions, a large list of regulatory documents regulating this area has been created. One of such international standard is EN 1672-2: 2020.

This document specifies common hygiene and cleanability requirements for machinery and machine components used in preparing and processing food for human (see informative Annex A) and, where relevant, animal feed processing to eliminate or minimize the risk of contagion, infection, illness or injury arising from this food to an acceptable level. It identifies the hazards which are significant to the use of such food processing machinery and describes design methods and information for use for the elimination or reduction of these risks.

Additional and/or deviant hygiene and cleanability requirements may be given in applicable C-standards for specific machines or categories of machinery.

Separate hygiene and cleanability requirements are contained in other EU-Directives or -Regulations (see Bibliography).

Examples of hygiene risks and acceptable solutions are given in the informative Annex B.

This document may also be used for machinery, components or other equipment used for other purposes than food preparing or processing, if cleanability is required.

Because of the high requirements on measurement conditions, grade 1 methods are normally not feasible for textile machinery.

Since the description of this document contains several possible areas of its application, we recommend that you familiarize yourself with their list in more detail by clicking on the link to our website. After all, it is possible that this document will become the beginning of a new way of development and achievement of the most productive results for your enterprise.

Physical processes and their international standardization

Considering the physical processes carried out in manufacturing enterprises as well as in various types of technological organizations, it is necessary to pay attention to safety aspects. After all, security considered from the side of enterprises can be not only financial, but also technical. In the 21st century, the issue of introducing international standards is becoming especially key, since economic systems are more and more exposed to globalization, and therefore technological interaction between countries is becoming more active. If you want your company to develop not only locally, but also globally, the availability of international standards is not a recommendation, but a strict necessity that will enable you to develop at a fast pace with the most productive results.
