What is EN ISO 14405-2: 2021 ?

Title: What is EN ISO 14405-2: 2021?

The International Organization for Standardization (ISO) is a global organization that develops and publishes a wide range of standards. One of these standards is EN ISO 14405-2: 2021, which is an international standard focused on providing guidelines for specifying geometrical product specifications (GPS) for dimensional and geometrical tolerances in technical product documentation.

EN ISO 14405-2: 2021 is specifically focused on linear sizes and dimensions and aims to ensure consistency and accuracy in specifying tolerances for various products. It establishes a clear framework for communicating tolerance requirements between manufacturers, designers, and customers. By adhering to this standard, companies can avoid misunderstandings and ensure that products meet the desired standards and quality levels.

Key Features of EN ISO 14405-2: 2021:

EN ISO 14405-2: 2021 provides a comprehensive framework for accurately representing and communicating the desired dimensions and tolerances on technical drawings. The standard consists of several key components, including:

Technical Product Documentation (TPD): This component outlines the specific tolerances and requirements for a product. It provides a clear and consistent way to communicate the desired dimensions and tolerances between different stakeholders.

Geometrical Product Specifications (GPS): This component defines the criteria for the dimensions and tolerances of a product. It provides a standardized method for specifying the size and shape of a product, including its dimensions, angles, and other relevant measurements.

Tolerance Limits: This component defines the maximum and minimum tolerances that can be allowed for each dimension of the product. It provides a clear and consistent way to specify the maximum and minimum tolerances for a product.

Expressions of Tolerance: This component defines the mathematical expressions that can be used to calculate the tolerance limits. It provides a clear and consistent way to specify the mathematical formula for calculating the tolerance limits.

Conclusion:

EN ISO 14405-2: 2021 is an international standard that provides guidelines for specifying geometrical product specifications for dimensional and geometrical tolerances in technical product documentation. It is focused on ensuring consistency and accuracy in specifying tolerances for various products. By adhering to this standard, companies can avoid misunderstandings and ensure that products meet the desired standards and quality levels.
