Standard

This standard specifies built-in safety measures aimed at preventing unexpected machine start-up (see 3.2) toallow safe human interventions in danger zones (see Annex A).This standard applies to unexpected start-up from all types of energy source, i.e.: Power supply, e.g. electrical, hydraulic, pneumatic.  Stored energy due to, e.g., gravity, compressed springs.  External influences, e.g. from wind;

IEC 60068-2-64:2008+A1:2019 demonstrates the adequacy of specimens to resist dynamic loads without unacceptable degradation of its functional and/or structural integrity when subjected to the specified random vibration test requirements. Broadband random vibration may be used to identify accumulated stress effects and the resulting mechanical weakness and degradation in the specified performance. This information, in conjunction with the relevant specification, may be used to assess the acceptability of specimens. This standard is applicable to specimens which may be subjected to vibration of a stochastic nature resulting from transportation or operational environments, for example in aircraft, space vehicles and land vehicles. It is primarily intended for unpackaged specimens, and for items in their transportation container when the latter may be considered as part of the specimen itself. However, if the item is packaged, then the item itself is referred to as a product and the item and its packaging together are referred to as a test specimen. This standard may be used in conjunction with IEC 60068-2-47:2005, for testing packaged products. If the specimens are subjected to vibration of a combination of random and deterministic nature resulting from transportation or real life environments, for example in aircraft, space vehicles and for items in their transportation container, testing with pure random may not be sufficient. See IEC 60068-3-8:2003 for estimating the dynamic vibration environment of the specimen and based on that, selecting the appropriate test method. The major changes with regard to the previous edition concern the removal of Method 1 and Method 2, replaced by a single method, and replacement of Annex A with suggested test spectra and removal of Annex C. Also included in this revision is the testing of soft packed specimens.

IEC 60068-2-2:2007 Deals with dry heat tests applicable both to heat-dissipating and non heat-dissipating specimens. For non heat-dissipating specimens, Tests Bb and Bd do not deviate essentially from earlier issues. The object of the dry heat test is limited to the determination of the ability of components, equipment or other articles to be used, transported or stored at high temperature. These dry heat tests do not enable the ability of specimens to withstand or operate during the temperature variations to be assessed. In this case, it would be necessary to use IEC 60068-2-14 Test N: Change of temperature. The dry heat tests are subdivided as follows:- Dry heat test for non heat-dissipating specimens with gradual change of temperature, Bb.- Dry heat tests for heat-dissipating specimens with gradual change of temperature, Bd. with gradual change of temperature, specimen powered throughout, Be. The procedures given in this standard are normally intended for specimens that achieve temperature stability during the performance of the test procedure. The main changes from the previous edition are as follows: Tests Ba and Bc have been deleted since they were more severe tests than Test Nb, IEC 60068-2-14: Change of temperature. Secondly it was considered justified to delete the 3 % value on the temperature difference between the chamber air and the wall temperatures. Thirdly it is proposed that the test specimen be powered throughout the test where required; and, finally, the annexes have been removed.

IEC 60068-2-1:2007 Deals with cold tests applicable to both non heat-dissipating and heat-dissipating specimens. For non heat-dissipating specimens, Tests Ab and Ad do not deviate essentially from earlier issues. Test Ae has been added primarily for testing equipment that requires being operational throughout the test, including the conditioning periods. The object of the cold test is limited to the determination of the ability of components, equipment or other articles to be used, transported or stored at low temperature. Cold tests cover by this standard do not enable the ability of specimens to withstand or operate during the temperature variations to be assessed. In this case, it would be necessary to use IEC 60068-2-14. The cold tests are subdivided as follows:- Cold tests for non heat-dissipating specimens: * with gradual change of temperature, Ab. - Cold test for heat-dissipating specimens: * with gradual change of temperature, Ad,* with gradual change of temperature, specimen powered throughout, Ae.The procedures given in this standard are normally intended for specimens that achieve temperature stability during the performance of the test procedure. Temperature chamber(s) are constructed and verified in accordance with specifications IEC 60068-3-5 and IEC 60068-3-7. Further guidance for dry heat and cold tests can be found in IEC 60068-3-1 and general guidance in IEC 60068-1. This sixth edition deals with cold tests applicable both to non heat-dissipating and heat-dissipating specimens. For non heat-dissipating specimens, Tests Ab and Ad do not deviate essentially from earlier issues. Test Ae has been added primary for testing equipment that requires being operational throughout the test including the conditioning periods.

IEC 60664-1:2020 deals with insulation coordination for equipment having a rated voltage up to AC 1 000 V or DC 1 500 V connected to low-voltage supply systems. This document applies to frequencies up to 30 kHz. It applies to equipment for use up to 2 000 m above sea level and provides guidance for use at higher altitudes. It provides requirements for technical committees to determine clearances, creepage distances and criteria for solid insulation. It includes methods of electrical testing with respect to insulation coordination. The minimum clearances specified in this document do not apply where ionized gases are present. Special requirements for such situations can be specified at the discretion of the relevant technical committee. This document does not deal with distances:– through liquid insulation. – through gases other than air. – through compressed air.This edition includes the following significant technical changes with respect to the previous edition:update of the Scope, Clauses 2 and 3,addition of 1 500 V DC into tables,new structure for Clauses 4 and 5,addition of Annex G with a flowchart for clearances,addition of Annex H with a flowchart for creepage distances,update of distances altitude correction in a new Table F.10.

This part of lEC 60320 sets the general requirements for appliance couplers for two poles andtwo poles with earth contact and for the connection of electrical devices for household andsimilar onto the mains supply.This document is also valid for appliance inlets/appliance outlets integrated or incorporated inappliances.The rated voltage does not exceed 250 V (AC) and the rated current does not exceed 16 A.Appliance couplers complying with this document are suitable for normal use at ambienttemperatures not normally exceeding +40 °C, but their average over a period of 24 h does notexceed +35 °C, with a lower limit of the ambient air temperature of −5 °C.Annex E provides test requirements for derating the operating current of an accessory whenused in ambient temperatures above +35 °C up to and including +90 °C.Appliance couplers are not suitable for:– use in place of plug and socket-outlet systems according to IEC 60884-1. – use in place of devices for connecting luminaires (DCLs) according to IEC 61995 orluminaire supporting couplers (LSCs). – use in place of installation couplers according to IEC 61535.
