: The 2010 update changed the "envelope criterion" (how form is controlled) to align with broader Geometrical Product Specification (GPS) standards, making it more compatible with modern digital measuring tools.

Fits are rated at standard reference temperatures (typically 20°C). An interference fit will act very differently on a hot summer shop floor compared to a cold inspection room.

A designer creating plastic parts on an FDM printer might use IT13 (very loose tolerances). A CNC machinist creating a metal valve spool might use IT5 (very tight). The ISO 286 PDF helps you justify to management why one part costs $2 and the other costs $200.
