SIST EN 13312-5:2002

Overview

EN 13312-5:2001 (CEN) is a European Standard that defines performance criteria for valves used in biotechnological processes where the presence of hazardous or potentially hazardous microorganisms creates risks to workers or the environment. The standard applies when valve use involves containment or when exposure to microorganisms is restricted for safety reasons. It focuses on ensuring valves meet safety, containment and hygienic requirements within biotechnology piping and instrumentation systems.

Key topics and requirements

While EN 13312-5:2001 is a performance-oriented document rather than a prescriptive design code, it addresses a set of technical topics and requirements relevant to biotech valves, including:

• Containment and leakage control - performance criteria to minimise release of microorganisms to workers or the environment.
• Cleanability and sterilizability - requirements to ensure valves can be effectively cleaned, sterilised or decontaminated in-process or during maintenance.
• Materials and surface finish - considerations for material compatibility with bioprocess media and resistance to cleaning/sterilisation agents.
• Sealing and closure performance - expectations for reliable seals under process conditions to prevent cross-contamination and leaks.
• Operation and actuation - functional criteria for manual, pneumatic or automated actuation compatible with containment strategies and process control.
• Maintenance, inspection and testing - performance-based requirements for validation, routine testing and maintenance intervals to sustain safe operation.
• Documentation and traceability - expectations for marking, technical documentation and records to support qualification and regulatory compliance.

(Note: EN 13312-5 defines performance criteria in the context of biotechnological safety; it does not prescribe specific designs or numeric test thresholds in this summary.)

Applications

EN 13312-5:2001 is directly applicable to:

• Manufacturers of valves and valve assemblies intended for biotech and pharmaceutical processes.
• Process, piping and instrumentation engineers designing bioprocess plants where containment of microorganisms is required.
• Validation, quality assurance and safety teams responsible for equipment qualification, cleaning validation and risk assessment.
• Procurement and maintenance departments selecting valves for aseptic or containment applications.

Use cases include containment of hazardous cultures, sterile transfer lines, bioreactor feed and waste lines, and any piping where worker/environmental exposure to microbes must be controlled.
