ISO 20457 places heavy emphasis on injection molded fittings. The tolerances here are tighter than for pipes because molds are machined to high precision.

CNC machining accuracy, steel type selection, wear over time, and the integration of moving cores directly impact the tool-dependent ( ) tolerance limits.
Wall thickness tolerances in ISO 20457 are derived from a calculation based on the nominal wall thickness ($e_n$). This is often presented in Table 4 of the standard.
