Report 242 Rev. 2 lists 19 December 2025 – 18 December 2028. Confirm current conformity and order applicability separately; no perpetual certification badge is assigned.
A dated audit scope does not replace a quotation, material test report or current order-specific certificate check.
Build one written requirement before comparing companies. Confirm the contracting legal entity and the actual producing factory for the requested item, then request a dated material specification and lot evidence. A company record, parent group and product-family description are different parts of that requirement.
