Purpose and objectives

SN EN ISO 14644-4:2022 provides comprehensive guidelines for the design, construction, and start-up of cleanrooms and associated controlled environments. Its main objectives are to ensure that cleanroom facilities meet specific performance criteria and comply with necessary regulations. The standard outlines procedures for planning, execution, verification, and maintenance, enabling organizations to effectively manage airborne particle concentration and other critical parameters that impact product quality and safety. By adhering to this standard, organizations can enhance their cleanroom operations, ensuring they meet both industry expectations and regulatory requirements.

Scope: who must comply

The SN EN ISO 14644-4:2022 standard applies to a wide range of industries where cleanrooms are essential for maintaining product quality and safety. Typical sectors include pharmaceuticals, biotechnology, electronics, aerospace, and healthcare. Organizations involved in the design and construction of cleanroom facilities must comply with this standard to ensure that their environments are appropriately controlled. Additionally, compliance is crucial from an Environment, Health & Safety (EHS) perspective, as it helps mitigate risks associated with airborne contamination and ensures the health and safety of personnel working in these environments.

How SN EN ISO 14644-4:2022 relates to other standards

This standard is part of the broader ISO 14644 family, which includes several related standards that address various aspects of cleanroom technology. For instance:

• ISO 14644-1 defines the classification of air cleanliness in cleanrooms and controlled environments.
• ISO 14644-2 outlines the monitoring of cleanroom performance and procedures for testing compliance.
• ISO 14644-5 focuses on the operations of cleanrooms, providing guidelines for maintaining ongoing compliance.

Revision history and current status

The SN EN ISO 14644-4:2022 was published by the International Organization for Standardization (ISO) and represents the latest revision in the series. The current status reflects updated methodologies and practices in cleanroom technology that enhance compliance and operational efficiency. Changes in this revision include improved guidelines for energy management in cleanroom design and more detailed performance parameters to ensure consistent verification and maintenance of cleanroom operations.
