Ask: Does this feature need to slide, press, or simply exist?
The standard provides a framework for specifying tolerances that balance the need for precision with the practical limitations of manufacturing processes.
ISO 20457 provides the mathematical basis for dimensional control in the plastic piping industry. The tolerance tables are designed to balance manufacturing feasibility (allowing for shrinkage and molding variations) with functional requirements (ensuring leak-tight joints).
