A new draft of the international cleanroom standard ISO 14644 Part 2 has been produced. The draft is open for public comments. The title of the standard is: “Cleanrooms and associated controlled environments — Part 2: Monitoring to provide evidence of cleanroom performance related to air cleanliness by particle concentration”.
ISO 14644-2 specifies the requirements of a monitoring plan, based on a risk assessment of the intended use. The data obtained provide evidence over time of continuing cleanroom or clean zone performance related to air cleanliness by particle concentration (ACP).
