Full title and description

St ISO 14644-5-2025 — Cleanrooms and associated controlled environments — Part 5: Operations. This second-edition standard defines requirements for establishing and maintaining an Operations Control Programme (OCP) to ensure consistent, documented control of cleanroom operations, including personnel management, gowning, material and equipment transfer, cleaning, maintenance and monitoring activities necessary to maintain specified cleanliness levels.

Abstract

ISO 14644-5:2025 specifies operational requirements and provides requirements for development and implementation of an Operations Control Programme (OCP) that supports the effective day-to-day operation of cleanrooms and associated controlled environments. The standard addresses policies and procedures for personnel and material flow, gowning and training, cleaning and maintenance programmes, installation and servicing of equipment, and establishment of monitoring and verification activities. Informative annexes give additional guidance on personnel management, gowning, training and cleaning. The document does not specifically address biocontamination control and excludes topics unrelated to contamination control or industry‑specific process requirements.

Scope

The standard applies to the operation and routine management of cleanrooms and associated controlled environments across industries. It requires organizations to develop and implement an Operations Control Programme (OCP) that documents the policies, procedures and supporting programs needed to maintain specified cleanliness levels. ISO 14644-5:2025 covers personnel management and gowning, movement of materials and portable equipment, installation and maintenance of fixed equipment, cleaning and special cleaning, and monitoring/verification activities. It does not set industry‑specific process requirements, replace health and safety regulations, or provide detailed equipment design specifications; biocontamination control is addressed in ISO 14698 series.

Key topics and requirements

• Establishment of an Operations Control Programme (OCP) linked to contamination control objectives and the facility's Contamination Control Strategy.
• Impact assessment methodology to identify operational risks and controls before implementing changes or new processes.
• Personnel management, training and qualification requirements, including documented gowning programmes and access control.
• Procedures and controls for transfer, receipt and movement of materials, portable equipment and stationary equipment installation/maintenance.
• Cleaning and maintenance programmes covering routine and special cleaning, selection of cleaning agents and cleaning frequencies.
• Monitoring and verification programmes for routine operational activities, including periodic reviews of OCP effectiveness.
• Documentation, record keeping and change control for operational procedures and corrective/preventive actions.
• Informative guidance on gowning, training, personnel management and cleaning provided in annexes.

Typical use and users

Used by facility managers, contamination control engineers, quality and compliance personnel, validation specialists and contractors responsible for cleanroom operation in sectors such as pharmaceuticals and biotechnology, medical device manufacture, semiconductor and microelectronics, aerospace, optics, and advanced manufacturing. It is applied when developing operational procedures, training programmes, cleaning regimes, material flow controls, maintenance schedules and monitoring plans to demonstrate and sustain required cleanliness levels.
