ISO 14644-18:2023

Overview

ISO 14644-18:2023 - "Cleanrooms and associated controlled environments - Part 18: Assessment of suitability of consumables" provides guidance for assessing whether personal and non-personal consumables are appropriate for use in cleanrooms, clean zones and controlled zones. The standard focuses on matching customer intended use requirements with supplier designed-use data, addressing cleanliness attributes (particles and chemicals in air or on surfaces), and treating biocontamination (viable particles, microorganisms, pyrogens) as a special property. ISO 14644-18 complements cleanroom operation standards such as ISO 14644-5.

Key topics and requirements

• Cleanliness attributes: assessment of particulate and chemical contamination potential of consumables in air and on surfaces.
• Special properties: identification and consideration of biocontamination risks (microorganisms, viable particles, pyrogens).
• Intended vs designed use: customers must specify intended functional and cleanliness requirements; suppliers must provide designed-use properties and supporting documentation.
• Assessment process: staged approach including initial comparison, detailed comparison, cleanroom suitability assessment, implementation and ongoing documentation.
• Documentation and traceability: requirements for customer documentation, supplier quality documentation and assessment records.
• Annexes and guidance: informative annexes provide examples of consumables, potential impacts on cleanroom cleanliness, verification/test methods and worked examples to support implementation.
• Scope exclusions: the standard does not cover design details of consumables, material functional performance testing (e.g., glove barrier properties), health & safety legal requirements, cleanability, raw process ingredients, transport containers, process media, or the functional performance of cleaning agents and lubricants.

Practical applications

ISO 14644-18 is used to:

• Select and qualify consumables (e.g., wipes, gloves, packaging, sample swabs) for contamination-sensitive processes.
• Define supplier requirements for cleanliness attributes and special properties.
• Perform risk-based assessments of consumable impacts on airborne and surface contamination.
• Support procurement, quality control, and validation activities to ensure consumables do not compromise cleanroom classifications.
• Inform cleaning agent and lubricant packaging requirements where packaging cleanliness affects controlled environments.

Who should use this standard

• Suppliers, manufacturers and distributors of consumables for controlled environments.
• Cleanroom operators, contamination control engineers and facilities managers.
• Quality, validation and procurement teams in aerospace, microelectronics, pharmaceuticals, medical devices, life sciences, cosmetics and food industries.
• Regulatory and compliance personnel who need documented suitability assessments for contamination control.
