The use of ISO 286-1:2010 provides several benefits, including:
Use this guide to understand when to use these tolerances and how to read the chart.
The shorter side of the angle (leg length) determines the tolerance.
The standard provides detailed tolerance tables that list the tolerance limits for different nominal sizes, ranging from 0 to 1000 mm (or 0 to 39.37 inches). The tables provide the tolerance limits for each tolerance class (f, m, c, and v). iso 2768 m tolerance chart
This guide explains the tolerance standard.
You have a plate with a chamfer dimension of 2 mm .
ISO 2768-m to:
General tolerances for angular dimensions are based on the length of the shorter leg of the angle in question. Length of Shorter Leg (mm) Tolerance Limit (Degrees/Minutes) Over 10 to 50 ± 0° 30' Over 50 to 120 ± 0° 20' Over 120 to 400 ± 0° 10' 📍 Understanding the Designations
| Nominal Dimension (mm) | Tolerance (± mm) | | :--- | :--- | | | ± 0.1 | | Over 3 up to 6 | ± 0.1 | | Over 6 up to 30 | ± 0.2 | | Over 30 up to 120 | ± 0.3 | | Over 120 up to 400 | ± 0.5 | | Over 400 up to 1000 | ± 0.8 | | Over 1000 up to 2000 | ± 1.2 | | Over 2000 up to 4000 | ± 2.0 |
The ISO 286-1:2010 tolerance chart provides a comprehensive guide to tolerance limits for linear sizes. The standard defines four tolerance classes: The use of ISO 286-1:2010 provides several benefits,
The standard defines tolerance zones based on a series of fundamental tolerances, which are calculated based on the nominal size of the feature. The tolerance zones are:
| Nominal Size (mm) | Tolerance Class | Lower Limit (mm) | Upper Limit (mm) | | --- | --- | --- | --- | | 10 | f | -0.012 | 0.012 | | 10 | m | -0.020 | 0.020 | | 10 | c | -0.040 | 0.040 | | 10 | v | -0.080 | 0.080 |
