This European Standard specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment and establishes procedures for the operation, maintenance and repair of refrigerating systems and the recovery of refrigerants.The term "refrigerating system" used in this European Standard includes heat pumps.This Part 2 of this Standard is applicable to the design, construction and installation of refrigerating systems including piping, components and materials. It includes ancillary equipment not covered in FprEN 378-1:2016, FprEN 378-3:2016 or FprEN 378-4:2016 which is directly associated with these systems. It also specifies requirements for testing, commissioning, marking and documentation. Requirements for secondary heat transfer circuits are excluded except for any protection requirements associated with the refrigerating system. Ancillary equipment includes, for example, fans, fan motors, electrical motors and transmission assemblies for open compressor systems.This standard applies:a) to refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard, e.g. ISO 13043;b) to secondary cooling or heating systems;c) to the location of the refrigerating systems;d) to replaced parts and added components after adoption of this standard if they are not identical in function and in the capacity.Systems using refrigerants other than those listed in Annex E of FprEN-378 1:2016 are not covered by this standard.This standard does not apply to goods in storage.This standard is not applicable to refrigerating systems which were manufactured before the date of its publication as a European Standard except for extensions and modifications to the system which were implemented after publication.This standard is applicable to new refrigerating systems, extensions or modifications of already existing systems, and for existing stationary systems, being transferred to and operated on another site.This standard also applies in the case of the conversion of a system to another refrigerant type, in which case conformity to the relevant clauses of parts 1 to 4 of the standard shall be assessed.

This European Standard specifies the requirements for the safety of persons and property, provides guidance for the protection of the environment and establishes procedures for the operation, maintenance and repair of refrigerating systems and the recovery of refrigerants.The term "refrigerating system" used in this European Standard includes heat pumps.This part of EN 378 specifies the classification and selection criteria applicable to refrigerating systems. These classification and selection criteria are used in parts 2, 3 and 4.This standard applies:a) to refrigerating systems, stationary or mobile, of all sizes except to vehicle air conditioning systems covered by a specific product standard e.g. ISO 13043;b) to secondary cooling or heating systems;c) to the location of the refrigerating systems;d) to replaced parts and added components after adoption of this standard if they are not identical in function and in the capacity;Systems using refrigerants other than those listed in Annex E of this European Standard are not covered by this standard.Annex C specifies how to determine the amount of refrigerant permitted in a given space, which when exceeded, requires additional protective measures to reduce the risk.Annex E specifies criteria for safety and environmental considerations of different refrigerants used in refrigeration and air conditioning.This standard is not applicable to refrigerating systems and heat pumps which were manufactured before the date of its publication as a European Standard except for extensions and modifications to the system which were implemented after publication.This standard is applicable to new refrigerating systems, extensions or modifications of already existing systems, and for existing stationary systems, being transferred to and operated on another site.This standard also applies in the case of the conversion of a system to another refrigerant type, in which case conformity to the relevant clauses of parts 1 to 4 of the standard shall be assessed.Product family standards dealing with the safety of refrigerating systems takes precedence over horizontal and generic standards covering the same subject.

This document specifies the requirements and test procedures for 360° visibility of sit on self-propelled industrial variable-reach trucks (herein after referred to as trucks) without a load, with a capacity greater than 10 000 kg in accordance with ISO 5053-1 and it is intended be used in conjunction with EN 16842 1.Where specific requirements in this part are modified from the general requirements in EN 16842 1, the requirements of this part are truck specific and to be used for sit-on self-propelled industrial variable-reach trucks with a capacity greater than 10 000 kg.This part of EN 16842 deals with all significant hazards, hazardous situations or hazardous events, relevant to the visibility of the operator for applicable machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.This document does not deal with rough-terrain variable-reach trucks (see EN 15830).

This document specifies the requirements and test procedures for 360° visibility of stand-on counterbalance trucks with a capacity up to and including 10 000 kg in accordance with ISO 5053 1 (herein after referred to as trucks) without a load and it is intended to be used in conjunction with EN 16842-1.Where specific requirements in this document are modified from the general requirements in EN 16842 1, the requirements of this document are truck-specific and are to be used for stand-on counterbalance trucks with a capacity up to, and including, 10 000 kg.This part of EN 16842 deals with all significant hazards, hazardous situations or hazardous events, relevant to the visibility of the operator for applicable machines when used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer.

This document specifies the requirements for safety systems which protect a vessel, a system of vessels, piping, accessories or assemblies from exceeding operating conditions.It is also applicable to safety related indicators and alarms, signals and warning devices when used in safety systems.Equipment connected together by piping of adequate capacity, free from potential blockages and which does not contain any valve that can isolate any part from the safety system, may be considered as a single pressure system when considering the requirements for overpressure protection.Safety systems include the interconnections between the equipment to be protected and any discharge location. This location can either be an outlet to atmosphere or the entry into a closed disposal system.NOTE The scope of this document and its relationship to the safety accessories and other protective devices described in the Pressure Equipment Directive are shown in Annex E.

This European Standard specifies the method for the strength calculation of the shell with respect to internal pressure of the valve.

This document defines classification criteria, test conditions and test procedures for performance testing of packaged refrigerating units for stationary cold room applications. This includes ductless units for cold storage applications at medium temperatures (MT) and low temperatures (LT) in either compact or split designs, fitted with electrically driven compressors, which work according to the vapour compression cycle.

This standard applies to rough-terrain slewing variable-reach trucks (herein-after referred to as ‘trucks’) as defined in ISO 10896-2 that have a specific seated operator’s position, on the left hand side of the boom, or centre position (excluding operator position on the right side of the boom).This standard specifies a static test method for determining and evaluating the operator’s visibility on a rectangular 1 m boundary close around the slewing rough-terrain variable-reach truck and on a 12 m visibility test circle. Performance requirements for visibility are specified in this standard.It applies to trucks for operation on work sites.

This standard specifies the requirements, also known as "relifing requirements", for the planned, intentional storage, control, and removal from storage of electronic, electrical and electromechanical parts which are intended to be used for space applications.This standard covers the relifing of all components as defined by ECSS-Q-ST-60 and ECSS-Q-ST-60-13.The relifing process is a lot quality control activity. The inspections and tests defined do not constitute an up-screening or up-grading of components to a higher level of quality than procured to.In line with ECSS-Q-ST-60, this standard differentiates between classes of components through different sets of standardization requirements.The classes provide levels of trade-off between assurance and risk. The highest assurance and lowest risk is provided by Class 1 and the lowest assurance and highest risk by Class 3. Procurement costs are typically highest for Class 1 and lowest for Class 3. Mitigation and other engineering measures can decrease the total cost of ownership differences between the three classes. The project objectives, definition and constraints determine which class or classes of components are appropriate to be utilised within the system and subsystems.- Class 1 components are described in Clause 4, 5 and 6- Class 2 components are described in Clause 4, 5 and 6- Class 3 components are described in Clause 4, 5 and 7The requirements of this document apply to all parties involved at all levels in the integration of EEE components into space segment hardware and launchers.This standard is applicable to all EEE parts covered by ECSS-Q-ST-60 and used in space programmes.This standard is not applicable to dice.This standard may be tailored for the specific characteristic and constrains of a space project in conformance with ECSS-S-ST-00.
