Gamma Sterilization

Gamma irradiation is a processing method used for a defined product configuration. It does not, by itself, establish a cleanroom classification, cleaning efficacy, frame compatibility, shelf life or compliance with a site SOP. ISO 14644-1 addresses airborne particle classification; it is not a product sterilization standard. EU GMP Annex 1 and IEST-RP-CC018 provide contamination-control and housekeeping context, but the facility must still qualify its own cleaning workflow.

The evidence library records gamma irradiation only in the sterile Polyester Knit Mop rows. The corresponding non-sterile rows remain non-sterile even when their nominal size, weight or construction is similar. Never inherit a sterilization statement from a family name, photograph or competitor page.

The current MIDPOSI evidence library confirms six Polyester Knit Mop SKUs: MID-MOP-PK-40G-N, MID-MOP-PK-40G-S, MID-MOP-PK-55G-N, MID-MOP-PK-55G-S, MID-MOP-PK-65G-N and MID-MOP-PK-65G-S. Each record is scoped to its own part number. Confirmed common dimensions are 40 cm × 12 cm; confirmed nominal weights are 40 g (±10%), 55 g (±10%) or 65 g (±10%). Sterile rows are separately identified from non-sterile rows.

The public evidence set does not confirm a gamma dose, SAL, expiry period, bioburden limit or dose-audit result for these mop records. Those values belong in the ‘needs further confirmation’ section until a current, SKU-scoped document is approved for publication. A sterilization method statement is not a substitute for a batch-specific certificate or the buyer’s own release requirements.

For a qualification review, request the exact sterile SKU, packaging specification, applicable sterilization or release document, lot traceability and any storage or expiry conditions. The assessment should also cover how outer packaging is handled before the mop enters the controlled area.
