Automatic document classification tasks can be divided into three sorts: supervised document classification where some external mechanism (such as human feedback) provides information on the correct classification for documents, unsupervised document classification (also known as document clustering), where the …

Security classification guidance is any instruction or source that sets out the classification of a system, plan, program, mission, or project. It is initially issued by Original Classification Authorities (OCAs) to document and disseminate classification decisions under their jurisdiction.

History, General and Old World is a classification used by the Library of Congress Classification system.

Grades A through to D refer to cleanroom cleanliness for the Pharmaceutical Industry for European, Australian and some Asian countries. Grade A is the cleanest, for sterile operations, through to Grade D for packing or support operations. These Grades can be related to the ISO Classes.

ISO 1

A class 100 cleanroom has 100 particles per cubic foot. By comparison your typical office space has between 500,000 and 1 million particles per cubic foot. Cleanrooms come in different classes from class 100 to 100,000.

Grade A: A classified space that satisfies European Medicines Agency (EMA) and PIC/S requirements to meet: ISO 5 measured via airborne ≥ 0.5 μm particulate.

ISO 8 cleanrooms, also known as Class 100,000 cleanrooms, can be modular or soft-walled and have a maximum particle count of 100,000 particles (≥0.5 um) per cubic foot of interior air. Cleanrooms By United is your premier source for high-efficiency ISO 8 clean rooms.

Grade C is equivalent to class 10,000 or ISO 7. Grade D is equivalent to class 100,000 or ISO 8.

ISO 14644-1 Cleanroom Standards

An ISO 7 clean room (Class 10,000 cleanroom) is a hard-sided wall manufactured facility that utilizes HEPA filtration systems to maintain air cleanliness levels of a maximum of 10,000 particles (≥0.5µm) per cubic foot.

must be brought into the cleanroom for any reason, ensure they stay concealed beneath appropriate cleanroom garments. Do not eat, smoke, or chew gum inside the cleanroom. Do not wear makeup, perfume, etc. inside the cleanroom.

Wear any cosmetics into the cleanroom. This includes mascara, eyeliner, hair products all all sorts, aftershaves, perfumes, fingernail polish. Don’t engage in any horseplay. No leaning on surfaces or equipment.

Microsystems are produced in the cleanroom. The yellow lighting is needed for photolithography to prevent unwanted exposure of photoresist to light of shorter wavelength.

A cleanroom is defined by ISO14644-1 as a room in which the concentration of airborne particles is controlled, and which is constructed and used in a manner to minimize the introduction, generation, and retention of particles inside the room and in which other relevant parameters, e.g. temperature, humidity, and …
