ISO 24442 Selection Criteria for Challenge Test Organisms Laboratory Testing Service Provided by Eurolab

Standard-Related Information

ISO 24442 is an international standard that outlines the selection criteria for challenge test organisms used in laboratory testing. This standard is part of a larger family of standards related to microbiological and chemical testing, which are crucial in ensuring product safety and quality.

The legal and regulatory framework surrounding ISO 24442 testing is governed by various national and international regulations, including:

  • European Unions (EU) Cosmetics Regulation

  • US Food and Drug Administration (FDA) guidelines for antimicrobial preservation

  • International Organization for Standardization (ISO) standards on microbiology and chemical testing

    • National standards that apply to this specific laboratory test include:

  • EN 14348:2017 (European Standard)

  • ASTM E2265-15 (American Standard)

  • TSE ISO 24442:2020 (Turkish Standard)

    • Standard development organizations, such as the International Organization for Standardization (ISO), play a crucial role in developing and maintaining standards. These organizations work with industry experts, regulatory bodies, and other stakeholders to ensure that standards remain relevant and effective.

    Standards evolve over time due to advances in technology, changes in regulations, or new scientific findings. For example, ISO 24442 has undergone revisions to incorporate new testing methods and criteria for challenge test organisms.

    Some key standard numbers related to ISO 24442 are:

  • ISO 24442:2020 (Selection Criteria for Challenge Test Organisms)
