22、 semiconductor devices (discrete devices and integrated circuits) and establishes provisions common to all the other parts of the series. In the case of contradiction between this standard and a relevant procurement specification, the latter should govern. 2 Normative references The following refere

23、nced documents are indispensable for the application of this document. For dated references, only the edition cited applies. For undated references, the latest edition of the referenced document (including any amendments) applies. IEC 60050 (all parts), International Electrotechnical Vocabulary (IEV

25、 (VEI) series. 4 Standard atmospheric conditions 4.1 All tests and recoveries, unless otherwise specified, shall be carried out under standard atmospheric conditions for testing: temperature: 15 C to 35 C; relative humidity: 45 % to 75 %, where appropriate; air pressure: 86 kPa to 106 kPa. 4.2 All e

26、lectrical measurements, as well as recoveries followed by measurements, shall however, be carried out under the atmospheric conditions: temperature: (25 5) C; relative humidity: 45 % to 75 %, where appropriate; air pressure: 86 kPa to 106 kPa. Page5 EN607491:20034.3 Before the measurements are made

27、, the specimens shall be stored until temperature equilibrium is reached with a view to stabilization. The ambient temperature during the measurements shall be stated in the test report. 4.4 During measurements, the specimens shall not be exposed to draughts, illumination or other influences likely

28、to cause error. 5 Electrical measurements 5.1 For environmental testing, the characteristics to be checked shall be selected from the “Acceptance and reliability” clause of the relevant part of the IEC 60747 or the IEC 60748 series; they are specified for each device category . 5.2 Measurement condi

29、tions: refer to the table “Conditions for the endurance tests” in the “Acceptance and reliability” clause of the relevant part of the IEC 60747 or the IEC 60748 series. 5.3 Initial measurements If upper specification limit and/or lower specification limit criteria are required only, it is left to th

30、e discretion of the manufacturer whether initial measurements are made or not. Initial measurements shall be made where individual values for an individual device are a criterion. 5.4 Measurements monitored during environmental testing To be stated, where appropriate. 5.5 Final measurements When the

31、 test is called for in the relevant specification as part of a sequence (sub-group) of tests, measurements are required only at the end of the sequence. 6 Use of electrically defective devices For certain tests, such as solderability or lead fatigue, electrically defective devices may be used.
