Why an ASSEMBLY standard IEC61439?
Regarding ASSEMBLIES,
safety of persons and property, and availability of electrical power depends on:
● Designing the overall “system” according to the relevant standards
●Controlling various interactions
●Protecting persons against any hazards
due to the ASSEMBLIES themselves
●Providing operating, maintenance
and modification capabilities

Evolutions of the ASSEMBLY Standard

10. Schneider Electric 10
- LoB LV – Nov 2010
The International ASSEMBLY standards
From IEC 60439-1 to IEC 61439-12
● Compared to the old IEC 60439-X, the new IEC 61439-X standards aim at:
● Better covering all ASSEMBLIES, especially the ASSEMBLIES based on ASSEMBLY Systems
● Improving safety by clarifying or increasing many requirements
● IEC 61439-2 is to be read in conjunction with IEC 61439-1, instead of IEC 60439-1 alone
● Tests identical to those in IEC 60439-1 do not need to be repeated
● Transitional periods may apply when implemented as regional, e.g. European (*), or national standards

Why a new standard ?
● 80% of the ASSEMBLIES worldwide do not comply with the
standard
● Requirements not always clear
● Role of Switchboard System manufacturer and Panel Builder not clear enough
●A Partially Type Tested ASSEMBLY (PTTA) concept abused and
misused
IEC61439-12 Standard
13. Schneider Electric 13
- LoB LV – Nov 2010
Main Changes
● Recognition of Original Manufacturer (Switchboard
System manufacturer) and ASSEMBLY Manufacturer
(Panel Builder)
● PTTA/TTA concepts replaced with (tested) ASSEMBLY
● Many clarified reinforced requirements
