IEC 60079-0:2007/ISH1:2008

Interpretation sheet 1 - Explosive atmospheres - Part 0: Equipment - General requirements

Applies to encapsulated semiconductor integrated circuits, including multichip integrated circuits, but excluding hybrid circuits. Gives details of the Quality Assessment Procedures, the inspection requirements, screening sequences, sampling requirements, test and measurement procedures required for the assessment of semiconductor integrated circuits, including digital, analogue and interface circuits.

Feuille d'interprétation 1 - Atmosphères explosives - Partie 0: Matériel - Exigences générales

S'applique aux circuits intégrés à semiconducteurs en boîtier, y compris les circuits intégrés polylithiques, mais à l'exclusion des circuits hybrides. Donne des détails sur les procédures d'assurance de la qualité, les exigences de contrôle, les séquences de sélection, les exigences pour les prélèvements, les essais et les mesures exigés pour tous les circuits intégrés à semiconducteurs, comprenant les circuits logiques, analogiques et d'interface.

INTERPRETATION SHEET
This interpretation sheet has been prepared by committee 31: Equipment for explosive
atmospheres, of IEC.
The text of this interpretation sheet is based on the following documents:
ISH Report on voting
31/768/ISH 31/779/RVD
Full information on the voting for the approval of this interpretation sheet can be found in the
report on voting indicated in the above table.
___________
Subclauses 26.8 and 26.9 of IEC 60079-0 (2007)
Following the discussions by the TC 31/WG 22 Task Group addressing the repeatability of the
thermal endurance to heat and thermal endurance to cold tests it was proposed that a
tolerance be clarified for the test periods in Edition 6, 31/744/DC was issued and comments
received and resolved as 31/752A/INF.
These interpretations are made available for edition 5 of this standard due to the current use
of that standard by manufacturers, conformity assessment schemes and national bodies by
means of this “Interpretation Sheet” as follows:
Details of interpretation:
Interpretation of subclause 26.8 Thermal endurance to heat and 26.9 Thermal endurance
to cold of IEC 60079-0 (2007):
Question: As it is unreasonable to consider them to be the exact test time, are the time
frames for the 24 h, 336 h (2 weeks) or 672 h (4 weeks) tests considered to be the minimum
times? If so, what is the maximum time?

Interpretation: The 24 h, 336 h and 672 h values are considered the minimum number of
+2
hours for each of the tests. It is practical that the time periods should not extend beyond 24
+30 +30
h, 336 h, 672 h.
0 0
It is intended that this interpretation will be introduced in IEC 60079-0 Edition 6 and therefore
an Interpretation Sheet will not be required for this or future editions.
