The evaluation of explosion-proof electrical equipment for certification is particularly important given the risk of explosion and must be minimized. This in order to ensure the safety of life, health of workers, to prevent damage to goods and the environment when they meet the essential security requirements at European level. Directive 2014/34 / EU states that equipment used in explosive atmospheres must be designed to operate without endangering the environment for which it is intended. This paper presents a comparison between the different types of cable glands for electrical apparatus by comparing some common characteristics that are important for maintaining the integrity of explosion protection. Consequently, this paper intends to be the precursor of a practical guide for the selection and implementation of different types of protection on the apparatus intended for use in areas with hazard of explosive atmospheres, both for designers and manufactures. This state of fact is negatively more emphatic because, lately, the groups of standards from this field in the world, Europe and Romania have a peculiar dynamic caused especially by the homogenisation and generalisation process opened and maintained by IEC.

Представлена разработанная блок-схема автоматизированной системы по сбору и обработки данных, а также структурная схема стенда для испытаний электрических машин постоянного и переменного тока. Предложено спроектированное устройство, которое защищает электродвигатель от превышения предельно допустимых параметров, указанных в паспорте на электрооборудование. Приведён пример работы на автоматизированном стенде с помощью виртуального прибора, созданного в программе LabVIEW. Установлено, что стенд позволяет получать визуализацию всех измеряемых параметров в реальном времени и сохраняет полученные данные в память компьютера. Таким образом, автоматизация стенда диагностики судовых электрических машин позволяет повысить эффективность проводимых на нём работ, путём сокращения трудоемкости и повышением качества выполняемых операций.The paper presents one of the options for increasing the efficiency of diagnostics of ship electrical equipment that has undergone repair by automating the test bench. The developed block diagram of an automated system for collecting and processing data, as well as a block diagram of a test bench for testing DC and AC electric machines, is presented. A designed device is proposed that protects the electric motor from exceeding the maximum permissible parameters indicated in the passport for electrical equipment. An example of work on an automated stand using a virtual device created in the LabVIEW program is given. It was found that the stand allows you to get a visualization of all measured parameters in real time and saves the data in computer memory. Thus, the automation of the diagnostic stand of marine electrical machines allows you to increase the efficiency of the work carried out on it, by reducing the complexity and improving the quality of operations.

Purpose The purpose of the paper is to present a framework for moving cross-border ePrescription (eP) and Patient Summary (PS) services forward, bearing in mind the needs and requirements of the European e-health space for cross-border eP and PS services, the limitations of the already developed solutions, as well as outcomes available from other domains. Design/methodology/approach The outcomes of previous and current large-scale pilot projects, aiming toward the delivery of electronic cross-border services, are examined. Integration of generic building blocks (BBs) is considered for the further development of cross-border eP and PS, in line with the European Directive on patients’ rights in cross-border health care. Findings The e-health domain is expected to greatly benefit from mitigating non-domain concerns such as those for electronic identification, end point detection, non-repudiation and the use of electronic signatures and trust establishments for basic cross-border public services in Europe. Research limitations/implications Research limitations are related to the fact that electronic identification, electronic signature and semantic issues have not been fully addressed yet at a European level to support cross-border services. Practical implications Practical implications are related to the cooperation, European level compatibility and sustainability of the underlying national infrastructures required to support reliable and secure exchange of medical data, as well as the readiness to address continuously evolving interoperability, legal and security requirements in a cross-border setting. Originality/value The need for consolidating the existing outcomes of non-health specific BBs is examined for two high-priority e-health services. Ongoing progress is presented, together with related issues that need to be resolved for improving technical certainty and making it easier to use health-care services abroad in cases of emergency.

Evaluation of explosion-proof protected electrical equipment in scope of certification is extremely important considering the risk of explosion that has to be minimized in order to ensure life safety and health of workers and to prevent damaging of property and the environment, as well as free movement of goods when they meet the essential safety requirements at European level. Most of the equipment operating in potentially explosive atmospheres is represented by electric motors, which in most situations act on various other elements (e.g. pumps, valves, fans etc.). Even if electric motors for explosive atmospheres are designed and manufactured following some of the same principles as the ones used for other electric machinery, they have certain particularities related to their field of use. Thus, a series of specific restrictions and tests are required to be considered in their case. The purpose of this paper is to present the importance of the specific tests for electric motors with type of protection increased safety „e” designed to be used in explosive atmosphere.

Explosion Risk

The explosion danger in all industries where explosive atmospheres generated by the mixture of combustible dusts or flammable gases with air may form, must be treated as a major hazard, as the explosions that may occur can seriously affect both health and safety people, as well as the environment. It is therefore necessary to assess the explosion risk and to establish appropriate measures to reduce it to acceptable levels in accordance with the requirements of the European Directives. An essential element in the assessment of the explosion risk for electrical and non-electrical equipment intended for use in potentially explosive atmospheres is the way in which an appropriate normal degree of protection is provided through the equipment housing (protection against touching of dangerous parts inside the equipment housing and protection against the ingress of dust and water inside it). The aim of the paper is to highlight compliance with the requirements of the ATEX Directive, given that this protection is a basic requirement for explosion protection and to present the important elements to be considered for the assessment of the normal degree of protection and the development of harmonized test methods with the requirements of European standards.

Solid Bodies

Carcasses of electrical or non-electrical equipment operating in potentially explosive atmospheres must provide a certain degree of protection against access to hazardous parts, penetration of solid bodies and/or water penetration, which must be tested according to the specifications of the Ex protection types. Normal protection classes are indicated by the international IP code followed by two characteristic digits referring to the protection against penetration of solid foreign bodies and water protection, followed by optional letters if required by the beneficiary according to the imposed conditions of use. Within the ENExEMEIP laboratory, have been developed laboratory tests to verify the first characteristic figure of the standard degree of protection according to the standardized European method. In the paper is presented the test stand of the large gauge equipment, a stand made with state-of-the-art equipment that provides the necessary performance for the accreditation of the test according to the standardized requirements. Checking dustproof protection to equipment used in areas where explosive atmospheres generated by combustion dust may occur is particularly important for assessing compliance with the requirements of the ATEX Directive [5], as this protection is a basic requirement for explosion protection.
