Units for use with additional ducting containing fluid to air heat exchangers and incorporating their own electrically powered fan system. For heating or cooling applications, the latter with or without dehumidification under frost-free conditions.
Deals with methods of carrying out thermal and volumetric tests on forced convection units containing fluid-to-air heat exchangers and incorporating their own fans. The units are for heating applications and the tests are to be carried out on units in an essentially clean condition.
This Standard applies to the cooling performance of portable air conditioners that have a rated cooling capacity of 19 000 W (65 000 Btu/h) or less and provide cooled air in one of the operating configurations described in Table 1. Note: The air conditioners described in this Clause include air...
This clause of Part 1 is replaced by the following. This part of IEC 60335 deals with the safety of electric heat pumps, including sanitary hot water heat pumps, air conditioners, and dehumidifiers incorporating motor-compressors and hydronic fan coils units, their maximum rated...
This Standard specifies requirements for automated eddy current test of seamless and welded tubes (except for submerged arc-welded tubes). The test employs the concentric coil technique or probe coil technique in which the full peripheral detection of the steel tubes is performed. The...
Diese Norm gilt für Maße, Ausführung und Werkstoffe von Halbrohrschlangen aus unlegierten, niedriglegierten oder nichtrostenden Stählen die vorwiegend an verfahrenstechnische
This part of IEC 60335 deals with the safety of electric HEAT PUMPS, including SANITARY HOT WATER HEAT PUMPS, AIR CONDITIONERS, and DEHUMIDIFIERS incorporating motor-compressors and HYDRONIC FAN COILS UNITS, their maximum RATED VOLTAGES being not more than 250 V for single phase...
This document specifies a procedure for the eddy current test with an encircling test coil for measuring defects on the outer surface of seamless round copper and copper alloy tubes. NOTE - The eddy current test method(s) required, together with the size range and acceptance level, are...
5.1 Absolute and comparative methods provide a means for sorting large quantities of ferrous parts of stock with regard to composition, condition, structure, or processing, or a combination thereof. 5.2 The comparative or two-coil method is used when high-sensitivity testing is required. The...
