A standard is not neutral. What it includes—and omits—reflects judgments about acceptable risk, cost, and performance. Engineers and policymakers negotiate these tradeoffs. DIN 17243, like all standards, sits at the intersection of safety and economy: tighter tolerances raise costs but lower failure likelihood. The standard’s clauses are the result of committees balancing those tensions. is a withdrawn German standard that specifies the
