ISO 14644 equivalents for EU GMP Grades

Have you ever used the live chat function on our website? It's an easy way for you to get in touch with us within office hours and ask a quick question to a Cleanroomshop team member.

We've noticed that we frequently get asked which ISO 14644 Classification is equivalent to EU GMP Grades for zones or cleanrooms, so we’ve put together a handy breakdown below.

What is the ISO 14644 approximate equivalent for the EU GMP grades?

• EU GMP Grade A is approximately equivalent to ISO 14644 Class 5
• EU GMP Grade B is approximately equivalent to ISO 14644 Class 5
• EU GMP Grade C is approximately equivalent to ISO 14644 Class 7
• EU GMP Grade D is approximately equivalent to ISO 14644 Class 8

For more information on the particulate concentration limits, we have a table that breaks it down on our cleanroom classifications page on our Connect 2 Cleanrooms website.
