Žemės ūkio mašinos. Priekiniai krautuvai. Sauga

This document specifies safety requirements and their verification for the design and construction of front loaders designed to be mounted on agricultural and forestry tractors (as defined in the Regulation EU 167/2013). It deals with all significant hazards, hazardous situations and events relevant to front loaders when used as intended and under the conditions of misuse which are reasonably foreseeable. This includes hazards related to the handling of unit loads during operations (for example, using bale forks), hazards related to mounting/demounting the lifting arms to/from the frame mounted on the tractor, and also hazards related to devices for mounting/demounting attachments to/from the lifting arms. In addition, it specifies the type of information on safe working practices. Hazards related to the mounted attachments with or without powered functions are excluded, as well as hazards related to visibility and those related to the mobile elevating work platform applications to a front loader, because the front loader is not designed to lift and/or transport people. Front loaders with fully or partially self-evolving behaviour or logic and/or with varying levels of autonomy are also excluded. Environmental aspects, other than noise, have not been considered in this document. Noise is not relevant for front loaders. This document is not applicable to front loaders which are manufactured before the date of its publication as EN.

This document specifies procedures to determine the thermal resistance of products whose thicknesses exceed the maximum thickness for guarded hot plate or heat flow meter apparatus. Most of the procedures described in this standard require apparatus that allows tests on specimens up to 100 mm thick . This document gives guidelines to assess the relevance of the thickness effect, i.e. to establish whether the thermal resistance of a thick product can or cannot be calculated as the sum of the thermal resistances of slices cut from the product, these guidelines complement the indications given in ISO 8302:1991[1] on the guarded hot plate apparatus. This document describes testing conditions which prevent the onset of convection which could take place in some products under the considered temperature differences and thicknesses.

This document defines product specific rules (PSR) for power electronic converter systems (PECS) and equipment. It specifies the process and requirements on how to conduct life cycle assessment (LCA) in the context of environmental product declarations (EPD) for PECS in the field of: — adjustable speed electrical power drive systems; — adjustable speed electrical power drive systems (PDS); — uninterruptible power systems (UPS); — static transfer systems (STS); — power supplies units (PSU); — central safety power supply systems (CSPSS); — bi-directional grid-connected power converters (GCPC). High voltage direct current (HVDC) equipment and other PECS (e.g. photovoltaic, windmills or e-vehicles) for which other dedicated product committees and specific standards exist are excluded from the scope. This document defines functional units and default scenarios in the product-specific context and common rules and guidelines for: a) the life cycle assessment (LCA), including the requirements for default scenarios; b) the Material Efficiency Assessment, including the requirements for default scenarios; c) the LCA report and Environmental Product Declaration (EPD). The LCA principles and framework are based on the ISO 1404x series (i.e. ISO 14040 and ISO 14044) and are therefore out of the scope of this document. In addition, this document defines specific Ecodesign assessment methods and specifications for the material efficiency aspects of PECS and equipment that are derived from published horizontal and generic standards for energy-related products (EN 45550 to EN 45559 series). This document specifies these generic standards in PECS context further through assessment requirements and default scenarios to support ecodesign and related customer information. Further, this includes definitions and specifications to enable material efficiency assessments at system level of PECS. It provides consistent and common criteria for considering material efficiency-related data to be operated by stakeholders along the lifecycle, supporting the building of digital product passport (DPP), data migration and interoperability of products and systems, including digital twins.

This document specifies dimensions, materials and performance requirements, including test methods, for combined temperature and pressure relief valves, of nominal sizes from DN 15 to DN 40, having working pressures ) from 0,3 MPa (3 bar) to 1,0 MPa (10 bar). Combined temperature and pressure relief valves control and limit the temperature and pressure of the water contained in a hot water heater to the valves rating pressure and a temperature not exceeding 100 °C and will prevent water to steam formation when other temperature controls fail. Combined temperature and pressure relief valves are classified having a maximum opening temperature range from 90 °C to 95 °C for class A and 75 °C to 80 °C for class B. They are not intended to act as an expansion valve and do not control cold water flow. Alone it does not constitute the control functions for a water heater. A combined temperature and pressure relief valve is an independently mechanically operating device, therefore operating without an external energy source. NOTE The use of the device specified in this document does not override the need to use controls (e.g. thermostats and cut-outs) which act directly on the power sources of water heaters (for more information, see Annex B).
