PMT characterization (physico-chemical, morphological and topographic) in a few words...
ISO 10993-19 provides a set of parameters and associated analytical methods for the PMT (physicochemical, morphological, and topographic) characterization of medical devices. These PMT parameters play an important role in the biocompatibility and clinical efficacy of medical devices.
What is the ISO 10993-19 standard?
ISO 10993-19 is part of the ISO 10993 series dedicated to the biological evaluation of medical devices.
It defines the principles and methods for PMT (physicochemical, morphological, and topographic) characterization of materials and devices, either prior to or in addition to biological testing.
This characterization provides a thorough understanding of the material, its surface, and its potential behavior in contact with the body.
PMT (physicochemical, morphological, and topographic) characterization in brief
PMT characterization aims to precisely describe:
- the chemical nature of the material
- the structure and morphology of the device
the surface - properties likely to influence biological interactions
Thus, ISO 10993-19 indicates the typical properties that can be taken into consideration in the context of PMT characterization of materials including polymers, metals, alloys, ceramics and natural macromolecules.

Our FAQ
Choosing an ISO 10993-19 certified laboratory is important for several reasons:
- Compliance with Regulatory Requirements: Regulatory agencies such as the European Medicines Agency (EMA) require medical device manufacturers to provide comprehensive data on the physico-chemical, morphological, and topographical characterization of materials used in their devices. Working with an ISO 10993-19 certified laboratory can help ensure that your testing meets these regulatory requirements.
- Expertise and Experience: An ISO 10993-19 certified laboratory has the expertise and experience necessary to conduct thorough material characterization testing. The lab personnel are trained in the specific techniques and methods required for these tests, and they have a deep understanding of the relevant regulations and guidelines.
- Quality Assurance: An ISO 10993-19 certified laboratory must adhere to stringent quality assurance and quality control standards. This means that the lab follows established protocols for sample preparation, testing, and data analysis, ensuring that the results are accurate, reproducible, and reliable.
- Risk Mitigation: Failure to adequately characterize the materials used in a medical device can lead to product recalls, safety issues, and legal liability. Choosing an ISO 10993-19 certified laboratory can help mitigate these risks by ensuring that your device materials are thoroughly tested and meet all applicable safety standards.
ISO 10993-19 is a standard that provides guidance on the physico-chemical, morphological, and topographical characterization of materials used in medical devices. The standard outlines several mandatory clauses that must be met to ensure that materials are thoroughly characterized and safe for use in medical devices. These include:
- Sample Preparation: This clause outlines the requirements for preparing samples for testing, including the size, shape, and number of samples required.
- Identification of Materials: This clause requires the identification of all materials used in the device, including any additives or impurities that may be present.
- Physico-Chemical Properties: This section outlines the tests required to evaluate the physico-chemical properties of the materials, such as solubility, pH, and viscosity.
- Morphological and Topographical Characterization: This clause requires the evaluation of the morphology and topography of the materials, including their surface area, porosity, and roughness.
- Surface Properties: This clause outlines the requirements for evaluating the surface properties of the materials, including surface tension, contact angle, and surface energy.
- Chemical Characterization: This clause requires the identification and quantification of chemical substances present in the device, including any additives or impurities that may be introduced during the manufacturing process.
- Biological Evaluation: This clause requires manufacturers to conduct in vitro and/or in vivo biological evaluations to assess the biocompatibility of the materials.
ISO 10993-19 outlines several methods for the characterization of materials used in medical devices. These methods can be broadly categorized into three groups: physico-chemical characterization, morphological characterization, and topographical characterization. Some of the main methods used in each of these areas include:
Physico-Chemical Characterization:
- Fourier Transform Infrared (FTIR) Spectroscopy
- Thermogravimetric Analysis (TGA)
- Differential Scanning Calorimetry (DSC)
- X-ray Photoelectron Spectroscopy (XPS)
- Atomic Absorption Spectroscopy (AAS)
- Inductively Coupled Plasma Mass Spectrometry (ICP-MS)
- Gas Chromatography-Mass Spectrometry (GC-MS)
Morphological Characterization:
- Scanning Electron Microscopy (SEM)
- Transmission Electron Microscopy (TEM)
- Atomic Force Microscopy (AFM)
- Confocal Laser Scanning Microscopy (CLSM)
- Light Scattering Techniques
- Mechanical Profiling
Topographical Characterization:
- Contact Angle Goniometry
- Surface Roughness Measurements
- Scanning Probe Microscopy (SPM)
- Optical Profilometry
Overall, these methods are used to evaluate various aspects of a material's properties, such as chemical composition, thermal stability, morphology, surface topography, and wettability. The results of these tests are critical for ensuring that the materials used in medical devices are safe, effective, and meet all regulatory requirements.
