Ensuring the cleanroom maintains the correct pressure gradient relative to surrounding areas to prevent cross-contamination.
ISO 14644-3: Cleanrooms and associated controlled environments — Part 3: Test methods provides guidelines for measuring and evaluating the performance of a cleanroom. It specifies both required and optional tests to verify the performance of the air cleanliness, as well as testing procedures for other crucial factors.
ISO 14644-3:2019 is the definitive guide to cleanroom test methods. Whether you are qualifying a new pharmaceutical facility, validating a semiconductor fab, or maintaining a medical device packaging line, this standard provides the rigorous, internationally accepted procedures you need to prove that your cleanroom performs as intended.

The document outlines two main categories of tests: those that are mandatory for classification and those that are recommended for validating the ongoing operation of the cleanroom. 2.1. Mandatory and Recommended Tests
⚠️ ISO 14644-3 does not apply to the measurement of products or processes within cleanrooms, nor does it address safety considerations associated with hazardous materials. Users are responsible for establishing appropriate safety and health practices before using the standard.
A: Mandatory status depends on your regulatory environment. For FDA-regulated pharmaceutical manufacturers and EU GMP-compliant facilities, adherence to ISO 14644-3 (or its regional adoptions) is effectively required to demonstrate cleanroom validation. For other industries, it represents best practice and is widely accepted by customers and auditors.
