ISO Cleanroom Standards — A Comprehensive Guide
Understanding the ISO standards that govern your cleanroom — what they require, what they mean in practice, and how to demonstrate compliance to your regulator
Inside this archive
ISO standards for cleanrooms can appear complex and technical — but understanding them is essential for anyone responsible for designing, operating, or maintaining a controlled environment. This guide provides a comprehensive, plain-language overview of the ISO standards most relevant to cleanroom and laboratory operations in Africa's regulated industries.
Relationship Between ISO 14644 and GMP Guidelines
ISO 14644 standards define the physical performance requirements for cleanroom environments — particle counts, air change rates, pressure differentials.
