ISO code system for tolerances on linear sizes

ISO 286 is a foundational international standard for the mechanical engineering and manufacturing sectors, defining the . It ensures the interchangeability of mass-produced parts by providing a standardized method for specifying the allowable variations in size (tolerances) and the relationship between mating parts (fits). Structure of the Standard The standard is divided into two primary parts:

Establishes the fundamental terminology, symbols, and mathematical bases for the code system. ISO 286-2: Tables of standard tolerance classes iso 286 pdf
