What is the ISO Tolerance Chart and How to Use it?

Published

on

Tolerance” is a term in manufacturing that defines accuracy and precision control, the allowable dimensional deviation for any mechanical part or system. For uniformity and efficient quality control, engineers and manufacturers use the ISO Tolerance Chart for this. It is ISO ISO-standardized chart illustrating linear, angular, form, and positioning tolerances for various geometrical features(shaft, holes, fits, etc).

ISO tolerance chart is an essential tool to decide whether manufactured parts are up to the desired specifications and standards or not. We will discuss the use of the ISO tolerance chart, its components, and its significance in manufacturing quality control.

Iso Standard Tolerance Chart- 2768

ISO 2768 tolerance is the worldwide used tolerance for linear and angular tolerances, widely applicable in CNC machining tolerances. Designers include ISO 2768 tolerance guidelines in their designs, whereas manufacturers understand and machine the designs to meet specified standard tolerances. This way, consistency can be maintained in the production.

Tolerance class is another factor you need to understand before moving on to chart components; Linear and angular tolerance are presented as fine, coarse, medium, and very-coarse tolerances, whereas positioning tolerances involve H, K, and L classes to define the tolerance levels.

The ISO Tolerance chart-2768 involves metric tolerances for geometrical and positioning dimensions; nominal length in the rows and crossbanding tolerances in the column.

Furthermore, there are two categories of ISO 2768 standards for tolerancing; ISO 2768- 1 and ISO 2768-2.

ISO 2768-1

ISO standard chart 2768- 1 deals with the general tolerances for linear and angular dimensions. It outlines the tolerances for length, angles,  external radius, and chamfer heights. Meanwhile, the tolerances are divided into fine, coarse, medium, and very coarse.

The typical ISO tolerance table/chart of 2768-1 is given below;

 

Type Nominal Length Range (mm and º) f (Fine) m (Medium) c (Coarse) v (Very Coarse)
Linear Dimensions 0.5 up to 3 ±0.05 ±0.1 ±0.2
Over 3 up to 6 ±0.05 ±0.1 ±0.3 ±0.5
Over 6 up to 30 ±0.1 ±0.2 ±0.5 ±1.0
Over 30 up to 120 ±0.15 ±0.3 ±0.8 ±1.5
Over 120 up to 400 ±0.2 ±0.5 ±1.2 ±2.5
Over 400 up to 1000 ±0.3 ±0.8 ±2.0 ±4.0
Over 1000 up to 2000 ±0.5 ±1.2 ±3.0 ±6.0

Angular Dimensions Up to 10º ±1º ±1º ±1º30′ ±3º
Over 10 up to 50º ±0º30′ ±0º30′ ±1º ±2º
Over 50 up to 120º ±0º20′ ±0º20′ ±0º30′ ±1º
Over 120 up to 400º ±0º10′ ±0º10′ ±0º15′ ±0º30′
Over 400º ±0º5′ ±0º5′ ±0º10′ ±0º20′

ISO 2768-2

ISO 276-2 involves positioning tolerance of geometrical features, like symmetry, flatness, perpendicularity, and run out. It also provides tolerances under three classes, H, K, and L. Furthermore, it also provides tolerances over nominal length. 

Here is a typical example of an ISO tolerance chart under the 2786-2 standard;

Type Nominal Length Range (mm) H K L
Flatness Up to 10 0.02 0.05 0.1
Over 10 up to 30 0.05 0.1 0.2
Over 30 up to 100 0.1 0.2 0.4
Over 100 up to 300 0.2 0.4 0.8
Over 300 up to 1000 0.3 0.6 1.2
Over 1000 up to 3000 0.4 0.8 1.6
Perpendicularity Up to 100 0.2 0.4 0.6
Over 100 up to 300 0.3 0.6 1
Over 300 up to 1000 0.4 0.8 1.5
