Electricity, equipment, cables - their regulation at the international level

Despite the fact that the world is developing at an accelerated pace and the number of applied technologies is increasing, the issue of their regulation and implementation in production processes is becoming more and more urgent. In the modern world, interaction between different states is a common phenomenon, and as a result, there is an integration and interchange of existing technologies. To reduce the distance and the possible inconsistency of certain aspects, international standards are being introduced, which in a certain way unify all systems. Today we will tell you about the main standards in the field of electrical engineering and documents regulating the use of equipment in this industry.

Food processing machinery - Filling machines and interchangeable equipment - Safety and hygiene requirements

EN 12463:2021

When it comes to the food industry, it is necessary to pay attention not only to the aesthetic characteristics of the final products manufactured, but also to the aspects of quality and suitability for consumption. After all, it is this area as well as each stage of production that is responsible for human health. One of the international standards governing food processing equipment is EN 12463: 2021.

This document applies to:

-   filling machines with cylinder and piston;

-   filling machines with feed intake hopper;

-   filling machines with vacuum hopper;

hereafter referred to as filling machines which process e.g. meat, cheese and other pasty substances, excluding dry or frozen materials. They pump foodstuff into casings or bring it to a following process. This document applies also to the interchangeable equipment for filling machines with which a wide range of additional functions can be implemented. For example: portioning, depositing, mincing, co-extruding, dividing and forming.

This document deals with all significant hazards, hazardous situations and events relevant to filling machines and interchangeable equipment (hereafter referred to as machines), when they are used as intended and under the conditions foreseen by the manufacturer and also the reasonable foreseeable misuse (see Clause 4).

These significant hazards, hazardous situations and events can arise during all the life phases including transportation, assembly, dismantling, disabling and scrapping of the machines.

This document is not applicable to machines which were manufactured before the date of publication of this document by CEN.

This international standard, like most other technological documents, has a certain number of amendments and clarifications, which is why we recommend that you familiarize yourself with them in detail before applying it in the activities of your organization.

International standards are a combination of safety and successful promotion

When scaling the activities of an organization, it is necessary to take into account that an increase in production capacity or the pursuit of the goal of increasing financial results should be carried out in conjunction with the structuring of the existing system. When it comes to the introduction of innovative technologies, it is necessary to have in place such international standards that will help to carry out this process as efficiently as possible. At first glance, in the globalizing world of technology, it may seem that the regulatory framework is only a complicating factor in the development process. Nevertheless, following the recommendations specified in the documents of the ISO and CEN standards institutes will help not only enter new international markets, but also significantly reduce the amount of possible financial losses. Therefore, think about having international standards in your company structure now.
