What SN EN ISO 21920-2:2022 covers

SN EN ISO 21920-2:2022 specifies the terminology and parameters necessary for defining surface texture using tactile measurement methods. This standard encompasses a wide range of surface texture characteristics, including profile point characteristics and geometric features that are critical in various manufacturing processes. It provides a framework for understanding how to quantify surface texture effectively, ensuring consistency and clarity across different applications. Notably, the standard outlines relevant surface texture parameters and their definitions, which are essential for successful implementation in quality assurance and product specifications. However, it does not address the surface textures of materials that do not require precise measurements or those outside the scope of geometrical product specifications.

How to implement SN EN ISO 21920-2:2022

Implementing SN EN ISO 21920-2:2022 involves several key steps to ensure compliance and effective integration into existing quality management systems. Organizations should start with a gap analysis to identify areas needing alignment with the standard. Next, comprehensive documentation of current practices and procedures must be developed or updated. Following this, training sessions for relevant staff are crucial to ensure understanding and proper application of the standard's terms and parameters. Once training is completed, organizations should conduct an internal audit to evaluate adherence to the new practices. Finally, a certification audit can be pursued to obtain formal recognition of compliance with SN EN ISO 21920-2:2022.
