As in Pharmaguideline SOP, the re-qualification period is defined as 1 year. Is there any reference guideline? Please specify the guideline and its chapter number.

Please clarify your question. Which re-qualification are you referring to?
Is it for manufacturing equipment, QC instrument, or utilities such as Water system, Air Handling system, Compressed air, Nitrogen generator, etc.?
