Using product information

Keep the page boundary clear

  • Typical data supports technical discussion; it is not a purchasing specification.
  • Material-level information is not finished-device approval. Suitability depends on the exact code, contact conditions and final device validation.
  • Lot documents apply to a specific production lot. Confirm current documents before design or acceptance.

From code to device validation
