ISO Class 7
ISO Class 7 refers to a specific cleanliness level for manufacturing spaces, particularly important in medical device production. It's like having a super-clean room where the air is carefully filtered to remove almost all dust and particles. Think of it as a hospital operating room, but even cleaner. When you see this term in job descriptions, it means the work takes place in these specially controlled environments where workers need to follow strict cleanliness procedures, wear special clothing (like gowns, masks, and booties), and understand clean room behaviors. This is part of a larger system called "ISO 14644-1" which defines different levels of clean rooms, with ISO Class 7 being a commonly required standard in medical manufacturing.
