How we handle documents

  • A product code (like KR-R3-10) identifies the item. A lot number identifies the batch. They are never the same thing.
  • Documents are published as we receive them. If a lot has no report online yet, the search says so plainly.
  • We only state what the report states. Methods and figures come from the document itself.
  • Need a document that isn’t listed? Write to us with the lot number.
