Two roles, two responsibilities
AS/NZS 61439 separates the original manufacturer — who designs the assembly system and carries out design verification — from the assembly manufacturer, who builds a specific board and performs routine verification. On many projects these are different companies, and the PM must confirm both sets of evidence exist.
Design verification
Design verification proves the design meets the standard. It can be done by test, by comparison with a tested reference design, or (for some characteristics) by assessment. Key characteristics include temperature rise, short-circuit withstand, dielectric properties, clearances and creepage, protection against electric shock, and mechanical operation.
Ask for the verification reports that match the actual ratings ordered: rated current (InA), rated short-time withstand current (Icw) and duration, form of separation and IP rating. A report for a different configuration is not evidence.
Routine verification
Every assembly must be routine-verified before dispatch: wiring and operation checks, dielectric test, protective circuit continuity, and confirmation of clearances, torque and labelling. Request the completed routine verification record for each board.
What to check at handover
Nameplate data consistent with the specification; declared rated values; the form of separation actually built; drawings and component schedules; the design and routine verification evidence; and installation and maintenance instructions. Missing items should be raised as non-conformances before acceptance.
