Refrigerating systems and heat pumps - Safety switching devices

1.1 This European standard establishes the requirements and tests applied to safety switching devices for limiting the pressure – here after called devices – to ensure that the maximum or minimum pressure, which is caused by a pressure generator in refrigerating systems and/or heat pumps, is maintained within the limits of the refrigerating system and/or heat pump. These devices are of special construction equipped with mechanically operated output contacts. NOTE: Devices may be wired directly into the control circuit of the compressor or may be connected through a relay or microprocessor/computer. Transducers/analogue devices are not covered by this standard. If more stringent specifications for special applications are necessary, these should be agreed between the customer and the manufacturer of the devices. 1.2 Different safety and control functions can be combined in one device. 1.3 This standard does not apply to devices used for control purposes.

Ventilation for buildings - Air diffusion - Aerodynamic testing and rating for mixed flow applicatio

This European Standard specifies methods for the laboratory aerodynamic testing and rating of air terminal devices for mixed flow applications, including the specification of suitable test facilities and measurement techniques. This standard applies to laboratory testing of ATD for technical characterisation. The standard gives only tests for the assessment of characteristics of the air terminal devices for mixed flow applications, under non-isothermal conditions with a cold jet. It does not cover the testing of isothermal or low velocity terminal devices which are covered by other published standards. This European Standard applies to ventilation or air conditioning systems designed for the maintenance of comfort conditions for buildings. It is not applicable in the case of systems for the control of industrial or other special process environments. In the latter case however, it may be referred to if the system technology is similar to that of the above mentioned ventilation and air conditioning systems. The principles described in this European Standard can also be used on site or in a lab for full-scale measurements.

Cranes and hoists — Selection of wire ropes, drums and sheaves

This International Standard specifies the minimum practical design factors, Zp, for the various classifications of mechanism, rope types, rope duties and types of spooling and demonstrates how these are used in the determination of the minimum breaking force of the wire rope. It specifies the selection factors for drums and sheaves for the various classifications of mechanisms, rope types and rope duties and how these are used in the determination of the minimum practical diameters of drums and sheaves that work in association with the selected wire rope. A list of types of cranes and hoists to which this standard applies is given in Annex A. Annex B gives factors, additional to those mentioned above, which might need consideration when selecting the wire rope and associated equipment.


Cranes — Wire ropes — Care and maintenance, inspection and discard

This document establishes general principles for the care and maintenance, and inspection and discard of steel wire ropes used on cranes and hoists. In addition to guidance on storage, handling, installation and maintenance, this document provides discard criteria for those running ropes which are subjected to multi-layer spooling, where both field experience and testing demonstrate that deterioration is significantly greater at the crossover zones on the drum than at any other section of rope in the system. It also provides more realistic discard criteria covering decreases in rope diameter and corrosion, and gives a method for assessing the combined effect of deterioration at any position in the rope. This document is applicable to those ropes used on the following types of cranes, the majority of which are defined in ISO 4306-1: a) cable and portal cable cranes; b) cantilever cranes (pillar jib, wall or walking); c) deck cranes; d) derrick and guy derrick cranes; e) derrick cranes with rigid bracing; f) floating cranes; g) mobile cranes; h) overhead travelling cranes; i) portal or semi-portal bridge cranes; j) portal or semi-portal cranes; k) railway cranes; l) tower cranes; m) offshore cranes, i.e. cranes mounted on a fixed structure supported by the sea bed or on a floating unit supported by buoyancy forces. This document applies to rope on cranes, winches and hoists used for hook, grabbing, magnet, ladle, excavator or stacking duties, whether operated manually, electrically or hydraulically. It also applies to rope used on hoists and hoist blocks. NOTE In view of the fact that the exclusive use of synthetic sheaves or metal sheaves incorporating synthetic linings is not recommended when single-layer spooling at the drum, due to the inevitability of wire breaks occurring internally in large numbers before there is any visible evidence of any wire breaks or signs of substantial wear on the periphery of the rope, no discard criteria are given for this combination.
