This document specifies the constructional and operational characteristics, the safety requirements, test methods and the marking of regulators and automatic change-over devices having a maximum regulated pressure of 4 bar, with a maximum capacity of 150 kg/h, for use with butane, propane and their mixtures in the vapour phase. The maximum supply pressures for devices covered by this standard are 7,5 bar for butane and 16 bar for propane and LPG. This document also applies to the safety devices which are included within regulating devices covered by this document. This document also includes requirements for: — adaptors for connecting to self-closing valves; — integral or auxiliary safety devices. This document covers devices used in locations where the temperature likely to be reached during use is between −20 °C and +50 °C Additional requirements for devices to be used at temperatures down to −30 °C and/or up to +80 °C are defined in Annex C. This document gives special requirements for: — devices intended to be used in caravans and motor caravans (Annex D); — devices intended to be used in boats (Annex M); — specific connections which are not defined in other standards (e.g. EN 15202:2012 for cylinder valve connections). NOTE: Boats considered in this document are recreational crafts covered by European Directive 2013/53/EU.

Orlaivių pagalbinė antžeminė įranga. Ypatingieji reikalavimai. 20 dalis. Antžeminiai elektros maitinimo įrenginiai

This European Standard specifies the technical requirements to minimise the hazards listed in Clause 4 which can arise during the commissioning, operation and maintenance of ground power equipment, when carried out in accordance with the specifications given by the manufacturer or his authorised representative. It also takes into account some performance requirements recognised as essential by authorities, aircraft and ground support equipment (GSE) manufacturers as well as airlines and service companies. This European Standard applies to: - ground power units either self-propelled or towable (Examples see Annex A); - ground power equipment when mounted on other GSE; - ground power accessories intended for ground power equipment (including accessories for fixed equipment). This European Standard does not apply to: - the electrical characteristics of the supply, the type of power supply system and related measures against contact; - any electrical supply system not intended for aircraft use; - the on-board electrical system of the aircraft. This European Standard does not establish requirements for noise and vibration. Noise and vibration are dealt with respectively in EN 1915 4 and EN 1915 3. This European Standard does not deal with hazards in respect to a standard automotive chassis and from other vehicles on the apron. This Part of EN 12312 is not applicable to ground power equipment which is manufactured before the date of publication of this European Standard by CEN. This part of EN 12312 is intended to be used in conjunction with EN 1915-1, EN 1915-2, EN 1915-3 (for vehicles) and EN 1915-4.

Kranai. Sauga. Projektavimas. Įrangos reikalavimai

This document specifies requirements for the design and selection of electrical, mechanical, hydraulic and pneumatic equipment used in all types of cranes and their associated fixed load lifting attachments with the objectives of protecting personnel from hazards affecting their health and safety and of ensuring reliability of function. NOTE Specific requirements for particular types of cranes, and for load lifting attachments, are given in the appropriate European Standard. The electrical equipment covered by this document commences at the point of connection of the supply to the crane (the crane supply switch) including systems for power supply and control feeders situated outside the crane, e.g. flexible cables, conductor wires or bars, electric motors and cableless controls. The principles to be applied for cranes transporting hazardous loads are given in this document. Particular requirements are given for cranes transporting hot molten metal. This document does not cover the detail design of individual items of equipment except with regard to their selection for specific aspects of use. The proof of competence calculations and related strength requirements or safety margins of equipment and components are not covered by this document. NOTE Some safety margins are given here for issues not covered in the EN 13001 series. Hazards due to noise are not covered by this document. They are addressed in safety standards specific to each type of crane. The specific hazards due to potentially explosive atmospheres, ionising radiation, and operation in electromagnetic fields beyond the range of EN 61000-6-2 are not covered by this document. The significant hazards covered by this document are identified in Annex A. This document is not applicable to cranes manufactured before the date of its publication.
