What is EN ISO 14468-2: 2021 ?

Title: What is EN ISO 14405-2: 2021 and Its Importance?

The International Organization for Standardization (ISO) is a worldwide 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. It is designed to eliminate errors and inconsistencies in the specification of tolerances, which can lead to disputes and errors in the manufacturing process.

EN ISO 14405-2: 2021 is divided into several sections, each of which covers a specific aspect of tolerance specification. These sections include:

* Section 1: Requirements for Tolerance, which provides the general principles for specifying tolerances and establishes the basis for the selection of tolerance criteria.

* Section 2: Tolerance Limits, which provides the maximum and minimum tolerances that can be used for each dimension.

* Section 3: Tolerance Units, which provides the units of measurement used for tolerance values.

* Section 4: Special Tolerances, which provides the tolerance criteria for specific dimensions, such as deep grooves and recesses.

* Section 5: Expressions of Tolerance, which provides the mathematical expressions used to calculate tolerance values.

Conclusion:

EN ISO 14405-2: 2021 is an important standard that provides a clear framework for specifying geometrical product tolerances in technical product documentation. By adhering to this standard, companies can ensure consistency and accuracy in the specification of tolerances, which can lead to better products and improved customer satisfaction. It is important for companies to carefully review the requirements and key features of EN ISO 14405-2: 2021 to ensure that their products meet the desired quality standards.
