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
41、) Subclause numbers of tests and performance requirements refer to the generic specification 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) I
42、n these tables: p is the periodicity (in months); n is the sample size; c is the acceptance 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 shal
43、l be measured is the temperature specified in the detail specification. This temperature shall 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”
44、. 6) The soldering tests (solderability and resistance to solder heat) shall only be applied 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 sh
45、all apply. 8) The thermistors shall be mounted by their normal means. 9) Vibration, bump, and shock tests are only conducted if required in the detail specification. The bump test and the shock test are alternatives. EN 62319-1-1:2005Licensed Copy: Wang Bin, ISO/EXCHANGE CHINA STANDARDS, 21/05/2010
