What is the Purpose of ISO 14644?

Introduction

ISO 14644 is a cornerstone standard in the cleanroom industry, providing a comprehensive framework for classifying air cleanliness by particle concentration. This set of guidelines is essential for industries where contamination control is critical, such as pharmaceuticals, biotechnology, and electronics. Understanding ISO 14644 ensures that cleanrooms are designed, maintained, and operated to the highest standards of cleanliness and safety

Cleanroom Classification

iso 14644-1: Airborne Particle Concentration

ISO 14644-1 specifies the classification system for cleanrooms based on airborne particulate levels. The standard defines nine ISO classes, with ISO Class 1 representing the highest level of cleanliness and ISO Class 9 the lowest. This classification helps industries identify and implement the necessary controls to maintain an appropriate environment for their specific applications.

Cleanroom Classifications Table

ISO Class	Maximum Particles/m³ (≥0.1 µm)	Maximum Particles/m³ (≥0.5 µm)
1	10	0
2	100	24
3	1,000	237
4	10,000	2,370
5	100,000	23,700
6	1,000,000	237,000
7	N/A	2,370,000
8	N/A	23,700,000
9	N/A	-

Testing and Monitoring
