The original DCR text shall be amended as follows:
Based on the review performed by the PSWG adhoc WG on ceramic capacitor generic specifications as implemented into ESCC3001 issue 2, the following modifications shall apply to this DCR:
a) All changes, including these modifications, have been implemented in the new DCR attachment 3001/033 draft 4E (which shall replace the original DCR attachment).
b) Ref. original DCR item 1) General:
The following additional editorial and technical amendments resulting from the changes made to the test requirements of the Generic Specification No. 3001, shall apply:
• Table 6: Climatic Test Sequence requirements are deleted.
• Table 6: Add notes applicable to Operating Life, to explain when the 1000h & 2000h measurements apply.
c) Ref. original DCR item 8) Para 4.4.3, Robustness of Termination: item is deleted (and replaced by item 6)
d) Ref. original DCR item 10) Table 2 & 6: units Gohm.nF are used for Insulation resistance (instead of sec)
e) Add new change items to this DCR as follows:
13) Appendix A for AVX (UK): replace the various specific document references for Microsectioning, and Internal and External Visual Inspection by “document as per PID.”
14) Para 4.2, Deviations to the Generic Spec: A new deviation is added to replace the Steady State Humidity test applicable to Chart F4 Group 1 testing (Qualification and Periodic Tests) by a Damp Heat Steady State test per IEC60068-2-78 (half no bias / half 100V bias, 40°C, 93%RH, 56days)(see 3001/033 draft 4D Para 2.1.1.2 for full details) (see note below)
Note: As has been agreed by the PSWG for ESCC 3009/034 (high Voltage type II ceramic chip capacitors) a similar deviation on Steady State Humidity has been applied in 3001/033 (also high voltage ceramic capacitors) on a similar basis.
i.e.
The PSWG-WG have suggested, since implementation of partial discharge requirements are still under discussion at CTB Passive WG level and could yet take some time, we should not make any major changes for AVX-NI (UK) in this ESCC Detail Specification (3009/034). Low Voltage Humidity test from Chart F4 being not applicable to high voltage, the PSWG-WG has therefore proposed to maintain, for the time being, the classical damp heat (half no bias / half 100V bias, 40°C, 93%RH, 56 days) from ESCC 3001 issue 1 for this high voltage ESCC detail specification (as a deviation to the latest 3001 issue 2).
15) Figure 2(a), VR Style, Variant 01: correct dimension Hmax to be 6.1mm (was 4.6mm)(this is a simple correction of a typographic error from previous revisions).
