What is EN ISO 22768-1:2014?

EN ISO 22768-1:2014, also known as the "Geometrical Product Specifications (GPS) - General tolerances - Part 1: Tolerances for linear and angular dimensions without individual tolerance indications," is an international standard that provides guidelines for dimensional tolerances in technical drawings.

Importance of EN ISO 22768-1:2014

The standard is crucial in various industries, especially manufacturing and engineering, as it ensures uniformity and accuracy in product design and production processes. By specifying tolerances for linear and angular dimensions, it helps maintain consistency and facilitates interchangability of components.

Key elements of EN ISO 22768-1:2014

The standard introduces several key elements to ensure effective use and interpretation of tolerances:

GPS Principles: The standard provides a brief of the Geometrical Product Specifications principles which are based on the ISO/TC 213 standards series. These principles guide the application of tolerances.

Linear Dimensions: It defines the tolerance zones and grades for linear dimensions without individual tolerance indications. These tolerance zones determine the acceptable deviation of size for a given dimension.

Angular Dimensions: The standard also specifies tolerance zones and grades for angular dimensions. It helps control variations in angles between surfaces or features.

Boundary Calculations: Calculations for boundaries and limits are provided to evaluate whether a component falls within the specified tolerance range or if it requires further action.

Conclusion

EN ISO 22768-1:2014 plays a vital role in ensuring standardized and accurate manufacturing processes. By defining tolerances for linear and angular dimensions, it helps facilitate efficient production, reduce errors, and promote component interchangeability. Manufacturers, engineers, and designers should adhere to this standard to achieve optimal quality control and consistency in their products.
