Part 2 simplifies Geometric Dimensioning and Tolerancing (GD&T) by creating general classes for structural features. Instead of four classes, Part 2 uses three tolerance classes denoted by capital letters: K (Medium) L (Low) 1. Straightness and Flatness
ISO 2768-1 divides tolerances into four classes, ranging from very fine to coarse: For high-precision parts. iso 2768 general tolerances pdf exclusive
