Full title and description

Sterilization of health care products — Biological indicators — Part 1: General requirements. This international standard specifies general requirements for the production, labelling, test methods and performance characteristics of biological indicators (including inoculated carriers and suspensions) and their components, for use in validation and routine monitoring of sterilization processes.

Abstract

ISO 11138-1:2017 defines the basic and common requirements applicable across the ISO 11138 series. It covers manufacture, labelling, test procedures and performance characteristics for biological indicators used to assess sterilization effectiveness, and notes exclusions (for example, microbiological test systems that rely solely on physical removal such as filtration). National or regional regulations may also apply.

Scope

Specifies general requirements for production, labelling, test methods and performance characteristics of biological indicators (including inoculated carriers and suspensions) and their components, intended for validation and routine monitoring of sterilization processes. Provides baseline/common requirements applicable to all parts of ISO 11138; when no specific subsequent part exists for a particular sterilization process, ISO 11138‑1 applies. It does not apply to microbiological test systems that rely solely on physical removal of microorganisms (e.g., filtration), though some elements may be relevant.

Key topics and requirements

• Definitions and terminology relevant to biological indicators.
• Requirements for manufacture and quality control of biological indicators and their components.
• Labelling, packaging and storage instructions to ensure traceability and correct use.
• Test methods for establishing performance characteristics (e.g., resistance, recovery, and shelf life).
• Performance criteria and acceptance limits for use in validation and routine monitoring.
• Guidance on applicability across different sterilization processes and interaction with process‑specific parts of ISO 11138.
• Notes on exclusions and interplay with national/regional regulations and other sterilization standards.

(Summary based on the standard's stated requirements and abstract.)

Typical use and users

Used by manufacturers of biological indicators, medical device and healthcare product manufacturers, sterilization validation laboratories, hospital sterile services departments, third‑party sterilization providers, regulatory bodies and quality assurance personnel involved in sterilization process validation and routine monitoring.

Related standards

ISO 11138-1 is the general‑requirements part of the ISO 11138 series. Other parts in the series address process‑specific biological indicators and guidance, for example ISO 11138-2, ISO 11138-3, ISO 11138-4, ISO 11138-5 (2017 editions) and ISO 11138-7 (guidance, later part). Together these define biological indicator requirements for ethylene oxide, moist heat, dry heat, low‑temperature steam/formaldehyde and related guidance.

FAQ

Q: What is this standard?

A: ISO 11138-1:2017 is the part of the ISO 11138 series that sets general requirements for biological indicators used to validate and monitor sterilization processes for healthcare products.

Q: What does it cover?

A: It covers production, labelling, test methods, performance characteristics, packaging and traceability requirements for biological indicators (including inoculated carriers and suspensions) and their components, and provides baseline requirements applicable across the ISO 11138 series.

Q: Who typically uses it?

A: BI manufacturers, sterilization validation labs, medical device manufacturers, hospital sterile services and regulators—any organization responsible for validating or monitoring sterilization processes.

Q: Is it current or superseded?

A: ISO 11138-1:2017 (Edition 3) is the current published edition (published March 2017). National adoptions and confirmations of the 2017 edition are in force; users should check national standards bodies for local implementations or amendments.

Q: Is it part of a series?

A: Yes — ISO 11138 is a multi‑part series. Part 1 contains general requirements; other parts address specific sterilization modalities (for example ISO 11138-2 through ISO 11138-5) and guidance (e.g., ISO 11138-7).

Q: What are the key keywords?

A: Biological indicator, sterilization validation, sterilization monitoring, inoculated carrier, suspension, labelling, performance characteristics, ISO 11138.
