Overview - EN ISO 14644-7:2004 (Separative devices)
EN ISO 14644-7:2004, published by CEN and identical to ISO 14644-7:2004, sets the minimum requirements for separative devices used with cleanrooms and associated controlled environments. Separative devices include clean air hoods, gloveboxes, isolators and mini-environments. The standard covers where these devices differ from conventional cleanrooms (see ISO 14644-4 and -5) and provides a generic framework for design, construction, installation, testing and approval of separative devices across industries.
Note key limitations: user requirements are agreed between customer and supplier; application-specific processes and regulatory matters (fire, safety, national rules) are not specified; the standard does not apply to full-suits.
Key topics and technical requirements
The standard addresses practical and testable elements for separative devices, including:
- Design and construction principles that differentiate separative devices from standard cleanrooms (rigid or soft-walled isolators, mini-environments, movable devices).
- Access devices (manual gloves, gauntlets, half‑suits, robotic interfaces) and guidance on their use and selection.
- Transfer devices and methods for moving product or materials in and out (pass‑throughs, airlocks, pods), including fail‑safe design considerations.
- Siting and installation recommendations for positioning devices within facilities.
- Testing and approval procedures:
- Glove breach test
- Operating differential pressure verification
- Leak testing and methods for demonstrating containment or classification
- Periodic testing and ongoing verification to maintain performance
- Informative annexes that expand on the separation continuum concept, air‑handling and gas systems, access devices, transfer-device examples, leak testing methods (including a Parjo leak test method) and related test details.
Applications and who uses this standard
EN ISO 14644-7 is relevant to organizations designing, manufacturing, validating or operating separative devices in industries where particle, chemical, gaseous or biological control is critical. Typical users include:
- Pharmaceutical and medical device manufacturers (isolators, aseptic processing)
- Biotechnology and life‑sciences labs (containment and sterile handling)
- Semiconductor and electronics manufacturers (mini‑environments, clean air hoods)
- Nuclear and hazardous-material handling operations (gloveboxes, containment)
- Cleanroom designers, facility engineers, validation and quality assurance teams, and suppliers of separative-device equipment
