Industrial: Procurement-Ready Attribute Fill

Derive attribute values only from {specifications} and {description} for {product_name}; never infer a figure that is not present. Prioritize the attributes a procurement engineer filters and compares on: exact dimensions, capacities and ratings (with consistent units), material/construction, operating conditions, model/reference identifiers, and any certification or standard explicitly stated. Express each value in its most precise, machine-comparable form — normalize units, keep tolerances intact, and split compound specs into discrete attributes so they can be filtered independently. Where a value is a range, preserve both bounds. Leave an attribute empty rather than approximating. Consistency and traceability matter more than completeness: a buyer must be able to cross-reference every value against a datasheet.
