37、uirements should be specified only when essential. 2 Inspection requirements 2.1 Procedures 2.1.1 For qualification approval, the procedures shall be in accordance with the generic specification IEC 62319-1. 2.1.2 For quality conformance inspection, the test schedules (Tables 1 and 2) include sampli
38、ng, periodicity, severities and requirements. The formation of inspection lots is covered by 3.5.7 of the generic specification. The following list applies to the test schedules developed in Tables 1 and 2: 1) Subclause numbers of tests and performance requirements refer to the generic specification
39、 IEC 62319-1 and Clause 1 of this specification. 2) Number to be tested: sample size as directly allotted to the code letter for IL in Table IIA of IEC 60410 (single sampling plan for normal inspection). 3) In these tables: p is the periodicity (in months); n is the sample size; c is the acceptance
40、criteria (permitted number of non-conforming items); D indicates a destructive test; ND indicates a non-destructive test; IL is the inspection level. 4) The temperature at which the zero power resistance shall be measured is the temperature specified in the detail specification. This temperature sha
41、ll be stated, where required, in the test schedule. 5) The specimens used for this group may, at the discretion of the manufacturer, be used for any subsequent group which is identified as being “destructive”. 6) The soldering tests (solderability and resistance to solder heat) shall only be applied
42、 where the thermistor has terminations which are appropriate for soldering. 7) Where the terminations are stated to be suitable for printed wiring applications, the appropriate test conditions in IEC 60068 shall apply. 8) The thermistors shall be mounted by their normal means. 9) Vibration, bump, an
43、d shock tests are only conducted if required in the detail specification. The bump test and the shock test are alternatives. EN 62319-1-1:2005 7 10) 100 % production testing shall be followed by re-inspection by sampling in order to monitor outgoing quality level by non-conforming items per million
44、(106). The sampling level shall be established by the manufacturer. For the calculation of x 106values, any parametric failure shall be counted as a non-conforming item. If one or more non-conforming items occur in a sample, this lot shall be rejected. 11) The number of cycles for a high breaking cu
45、rrent device (Imax100 A) in the cycle life test shall be specified in the detail specification. 12) The duration for a high breaking current device (Imax100 A) in the trip endurance test shall be specified in the detail specification. 13) The subgroup B2 tests are only conducted if required in the d
