Purpose and objectives

The SN EN ISO 21920-2:2022 standard serves as a critical framework for defining surface texture specifications within geometrical product specifications (GPS). Its primary objective is to standardize the terminology and parameters associated with surface texture, ensuring consistency and clarity in product specifications across various industries. By establishing a common language, the standard aids manufacturers and consumers in understanding surface texture characteristics, ultimately enhancing product quality and performance. Compliance with ISO 21920-2:2021 is essential for companies aiming to meet international quality standards and improve their competitive edge.

Scope: who must comply

The ISO 21920-2:2021 compliance requirements apply broadly across several industries, including manufacturing, automotive, aerospace, and precision engineering. Organizations involved in the design, production, and quality control of products that require specific surface texture characteristics must adhere to this standard. Typical company profiles include manufacturers, quality assurance teams, and engineering firms that focus on geometric product specifications. By aligning with the general terms and definitions outlined in the standard, companies can ensure their products meet rigorous international quality benchmarks.

How SN EN ISO 21920-2:2022 relates to other standards

The SN EN ISO 21920-2:2022 standard is part of a broader framework of standards related to geometrical product specifications. Key related standards include:

• ISO 12085:1998 – This standard provides additional guidelines on the measurement of surface texture, complementing the specifications laid out in ISO 21920-2.
• ISO 4287:1999 – It focuses on the characterization of surface texture parameters, which are essential for understanding and applying ISO 21920-2 compliance.
• ISO 13565-2:1998 – This standard details methods for assessing surface texture, further supporting compliance efforts with ISO 21920-2.

Revision history and current status

The SN EN ISO 21920-2:2022 standard is published by the International Organization for Standardization (ISO), reflecting the latest revisions and updates in surface texture specifications. The current revision year is 2022, and this update has incorporated changes to improve clarity in terminology and measurement methods. The revisions also aim to align more closely with advancements in technology and industry practices, ensuring that organizations can effectively implement ISO 21920-2:2021 compliance requirements.
