The following compilation is intended as a highly concentrated insight into the contents of the remaining standards of the ISO 14644 series on general cleanroom technology.

ISO/CD 14644-812 addresses molecular contamination, i.e. the contamination risks caused by airborne molecules - an area of utmost relevance in microelectronics and aerospace, but so far of less impact for the pharmaceutical industry. This standard will focus on classification as well as on measurement and analysis issues. Four classes of compounds are distinguished: acids, bases, organics and inorganics; and five contaminant categories: biotoxics, condensables, corrosives, dopants and oxidants.
