ISO Class 8
ISO Class 8 refers to a standard of cleanliness in special manufacturing rooms called cleanrooms, which are crucial for making medical devices. Think of it like a super-clean workspace where the air is constantly filtered to remove dust and particles. This level of cleanliness is less strict than what's needed for making computer chips (which need ISO Class 5 or 6) but is clean enough for most medical device assembly. When you see this term in resumes or job descriptions, it means the person has experience working in these controlled environments where they need to wear special clothing (like gowns, hairnets, and booties) and follow strict cleanliness procedures.
