Background |
Cleaning and associated validation requirements are essential for the safe use of reusable devices. In the past, test methods and associated endpoints for cleaning validations have varied worldwide. Recent international standards have updated the requirements to include cleaning endpoints and requirements for the use of test soils for demonstrating cleaning efficacy of washer-disinfectors.
Methods |
A quantitative comparison of test soils used in cleaning efficacy studies was conducted using a new standardized test method as published in Annexe B ISO 15883–5:2021. Test soils included Artificial Test Soil (ATS 2015), Blood Test Soil (BTS), Coagulated Blood, Defibrinated Blood Soil (DBLSO), Modified Coagulated Blood Soil, Two Component Blood Test Soil and the UK Test Soil (Edinburgh Soil).
Conclusion |
All the test soils demonstrated acceptable performance in accordance with the standard.
