Full title and description

Implants for surgery — Cleanliness of orthopedic implants — General requirements. This ISO standard specifies requirements and test methods for determining and controlling the cleanliness of orthopaedic implants, covering in‑process and final cleaning and framing cleaning validation and controls within a risk‑management approach.

Abstract

ISO 19227:2018 establishes general requirements for the cleanliness of solid orthopaedic implants, including guidance on cleaning process design, validation, sampling and test methods (visual inspection, bioburden, endotoxins, organic/inorganic contaminants and particulate matter) and associated documentation and controls. It excludes requirements for packaging or sterilization and does not apply to liquid or gaseous implants or to cleaning performed by the user.

General information

• Status: Published (current international standard; under normal ISO review cycle subject to revision status notes).
• Publication date: 21 March 2018.
• Publisher: International Organization for Standardization (ISO).
• ICS / categories: 11.040.40 — Implants for surgery, prosthetics and orthotics.
• Edition / version: Edition 1 (2018).
• Number of pages: 17–18 pages (national catalogues list 17 pages; ISO metadata shows 18 pages).

Scope

Defines requirements for the cleanliness of orthopaedic implants and the test methods used for cleaning‑process validation and controls, based on a risk management process. Applies to in‑process cleaning and final cleaning of solid implants. Excludes packaging and sterilization requirements (covered by other standards), liquid or gaseous implants and cleaning performed by the user or under user responsibility.

Key topics and requirements

• Risk‑based framework for cleaning process design, validation and ongoing verification.
• Definition of cleaning family, worst‑case specimens and critical steps for representative validation.
• Sampling and test specimen preparation to represent production parts for validation and routine control.
• Test methods and acceptance-related controls: visual inspection, bioburden, bacterial endotoxins, organic contaminant extraction/analysis, inorganic contamination, particulate contamination and related measurements.
• Documentation and records: validation reports, test records, procedures, nonconformance handling and change control.
• Interface with quality and risk management systems (e.g., ISO 13485, ISO 14971 principles) and with standards covering packaging and sterilization which remain out of scope for this document.

Typical use and users

Manufacturers of orthopaedic implants and contract manufacturers, quality and regulatory affairs teams, process engineers responsible for cleaning and validation, third‑party testing laboratories that perform cleanliness and bioburden testing, and regulatory reviewers. The standard is used to define and validate cleaning processes, prepare validation documentation, and support premarket submissions and post‑market quality systems; it is also referenced in regulatory/recognition listings.

Related standards

Commonly referenced alongside: ISO 13485 (medical device quality management), ISO 14971 (application of risk management to medical devices), ISO 11607 (packaging for terminally sterilized medical devices) and the ISO 11137 series (radiation sterilization). These standards cover complementary topics—quality system requirements, risk methodology, packaging validation and sterilization—that interface with cleaning and final device preparedness.

FAQ

Q: What is this standard?

A: ISO 19227:2018 is an international standard that specifies general requirements and test methods for the cleanliness of orthopaedic (surgical) implants, including guidance on validation and process controls.

Q: What does it cover?

A: It covers in‑process and final cleaning of solid orthopaedic implants, sampling and test methods (visual, bioburden, endotoxins, organic/inorganic contaminants, particulates), validation strategy, documentation and ongoing verification; it explicitly excludes packaging and sterilization requirements and liquid/gaseous implants.

Q: Who typically uses it?

A: Implant manufacturers, contract manufacturers, validation engineers, quality/regulatory personnel, testing laboratories and competent authorities reviewing cleaning validation and device cleanliness data.

Q: Is it current or superseded?

A: ISO 19227:2018 is the first edition published in March 2018 and is published/active. ISO standards are subject to periodic review; ISO metadata notes this document is in the normal review cycle and there are project indications for revision activity. Users should confirm the current status with their national body or ISO catalogue before relying on the standard for regulatory submissions.

Q: Is it part of a series?

A: Not as a numbered multi‑part series, but ISO 19227 sits within the broader family of medical device and implant standards and is commonly used together with other ISO standards addressing quality systems, risk management, packaging and sterilization (e.g., ISO 13485, ISO 14971, ISO 11607, ISO 11137).

Q: What are the key keywords?

A: Orthopaedic implant cleanliness; cleaning validation; bioburden; endotoxin; particulate contamination; risk management; implant manufacturing; process verification.
