ISO 10993-14 Degradation Products Testing for Ceramics
The ISO 10993 standard is a cornerstone of biocompatibility testing, ensuring that medical devices are safe and compatible with the human body. Specifically, ISO 10993-14:2016 addresses the assessment of degradation products from ceramics used in medical devices. This service provides comprehensive testing for ceramic materials to ensure they do not release harmful substances into the patient's environment.
Ceramics are widely used in orthopedic implants, dental devices, and other surgical instruments due to their biocompatibility, mechanical strength, and resistance to corrosion. However, over time, ceramics can degrade under physiological conditions, releasing degradation products that may interact with the body. These degradation products must be rigorously tested for their potential toxicity and bioavailability.
The testing process involves several steps: initial material characterization, immersion of the ceramic sample in a simulated body fluid (SBF), and subsequent analysis of the leachate to identify and quantify any released compounds. The standard outlines specific methods for extraction, separation, identification, quantification, and evaluation of these degradation products.
Understanding the degradation behavior of ceramics is crucial for medical device manufacturers, as it directly impacts product safety and efficacy. The test results can inform design modifications, material selection, and regulatory compliance. This service ensures that ceramic materials meet stringent biocompatibility requirements, thereby protecting patient health.

Scope and Methodology
The scope of ISO 10993-14 Degradation Products Testing involves evaluating the release of substances from ceramics when exposed to biological environments. The methodology typically includes:
- Material characterization: Identifying the chemical composition and crystalline structure of the ceramic.
- Immersion in SBF: Submerging the sample in a solution mimicking human blood or tissue fluid for a specified duration (e.g., 28 days).
- Extraction: Using appropriate solvents to extract potential degradation products from the leachate.
- Analysis: Employing analytical techniques such as HPLC, ICP-MS, and FTIR to identify and quantify released compounds.
- Evaluation: Assessing the bioavailability and toxicity of identified substances using in vitro or in vivo assays.
