1.1 This document specifies requirements for design, performance, safety and hygiene of refrigerated bulk milk coolers and the related methods of test.

NOTE The informative Annex J gives some elements regarding the estimation and calculation of energy consumption.

This document deals with all significant hazards, hazardous situations and events relevant to bulk milk coolers on farm, when they are used as intended and under the conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).

It applies to refrigerated bulk milk tanks with air-cooled condensing units and automatic control intended for installation on farms or at milk collection points. It applies to tanks for two milkings (24 h), four milkings (48 h) and six milkings (72 h), in which the cooling takes place totally (non-pre-cooled milk) or partially (in case of pre-cooled milk) within the tank. It also applies to tanks in combination with a continuous system of milking (e.g. milking with robot).

1.2 This document does not cover:

— mobile tanks;

— tanks intended to be tilted for drainage;

— equipment for delivering the milk to the tank;

— equipment for pre-cooling of the milk;

— the hazards due to the use of other energy than electrical energy;

— pressure aspect of vacuum tanks (i.e. tanks where the inner part of the vessel is designed to operate at a pressure below atmospheric pressure).

1.3 Noise is not considered to be a significant hazard, but relevant for bulk milk coolers. This document therefore includes information in 7.1 and in Annex A concerning the manufacturer's declaration of the noise emission level of the cooler.

1.4 This document does not cover the calibration requirements for the tank to be used as a system for payment purpose.

1.5 This document is not applicable to bulk milk coolers on farm which are manufactured before the date of its publication as EN.

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 sy ...

This International Standard specifies safety requirements and/or protective measures, applicable to EDM equipment and EDM systems, such as

— manually controlled EDM die sinking or EDM drilling machines;

— numerically controlled EDM die sinking or EDM drilling machines, and

— numerically controlled EDM wire cutting machines.

intended to be adopted by persons undertaking the design, construction, installation and/or supply of such equipment. This International Standard also includes information to be provided by the manufacturer to the user.

This International Standard is not applicable to arc eroding and electro-chemical machining equipment.

This International Standard takes account of the precondition of the intended use as well as the reasonably foreseeable misuse, in normal workshop environments and non-explosive atmospheres, including transportation, installation, setting, maintenance, repair and dismantling for removal or disposal of EDM equipment and EDM systems.

This International Standard is also applicable to auxiliary devices essential for EDM processing.

This International Standard deals with all significant hazards, hazardous situations or hazardous events relevant to EDM equipment and EDM systems, where they are used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).

This International Standard is intended to apply to machines manufactured after the date of publication of this International Standard.

This document specifies the measurement method and conditions to obtain reproducible and comparable noise levels on-board all kinds of vehicles operating on rails or other types of fixed track, hereinafter conventionally called "unit", except for track maintenance vehicles in working modes.

NOTE For constant speed tests the concept of "comparability" needs further caution, as this term is used as well to classify the measurement precision grade related to track roughness and track decay rates given in this document. Nevertheless, the measurement may be acceptable as type test on a track of controlled acoustic quality, but not compliant to the track specification given in this document.

This document is applicable to type testing. It does not include all the instructions to carry out monitoring testing or evaluation of noise exposure of passengers or drivers over a whole journey.

This document is not applicable to guided buses.

It provides measurement procedures for vehicle interior noise:

— when the vehicle is moving at constant speed;

— when the vehicle is stationary;

— when the vehicle is accelerating or decelerating;

— in the driver's cab when an external warning horn is sounding.

NOTE In general, a vehicle type acceptance test would require only a selected subset of these tests to be performed.

It does not provide measurement procedures for:

— audibility or intelligibility of any audible signals;

— assessment of warning devices other than warning horns.

The assessment of noise exposure of train crew due to operational conditions is not in the scope of this document.

The results may be used, for example:

— to characterise the noise inside these units;

— to compare the internal noise of various units on a particular track section;

— to collect basic source data for units.

The test procedures specified in this document are of engineering grade (grade 2), that is the preferred one for noise declaration purposes, as defined in EN ISO 12001. If test conditions are relaxed for example as done for monitoring of in-service trains, then the results are no longer of engineering grade.

The procedures specified for accelerating and decelerating tests are of survey grade.

This document specifies safety and hygiene requirements of clipping machines (hereafter referred to as machine) for closing of casings filled with foodstuffs (hereafter referred to as product) by using a clip, and which are intended to be used in butcheries, meat processing factories, main kitchens and other food processing factories.

Clipping machines are used to close tubes with a single clip (one side) or a double clip (end locking and start locking).

The machines are equipped with closing tools (punch/die), which create the closure by deforming the locking element (clip).

This document deals with all significant hazards, hazardous situations and hazardous events relevant to machinery when it is used as intended and under conditions of misuse which are reasonably foreseeable by the manufacturer (see Clause 4).

This document covers the following types of machines:

— semi-automatic machine (see Figure 1 and Figure 2);

— automatic machine (see Figure 3).

This document does not cover any machines whose closing procedure is only performed manually.

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