GMP Annex 1 Guidelines

"Good manufacturing practice (GMP) describes the minimum standard that a medicines manufacturer must meet in their production processes." (

The governing cleanroom standard is ISO 14644, which is a suite of standards covering a breadth of cleanroom design and build, maintenance testing, etc.

Generally speaking, the pharma market has more stringent levels of control than advanced manufacturing, so the GMP Guidelines take reference from the ISO standards, adding a few layers of compliance with different stipulations around occupancy states, validation states, and more.

A GMP-compliant cleanroom will also have an ISO classification, but an ISO 14644-1:2015 graded cleanroom may not qualify for a GMP cleanroom grade, as GMP Annex 1 requires extra conditions (above those stipulated in ISO 14644-1:2015) to meet the minimum requirement for medicines manufacture.

The GMP Guidelines reference the ISO standard, both with an at-rest particulate contamination level of acceptance and as an operational level of acceptance. As client’s working towards GMP compliance go through go through a formal DQ IQ OQ PQ protocol; when it comes to PQ, they will look at their process and assess that their SOPs are in-line with the amount of particulate that’s getting generated.

This process gives the opportunity to formalise procedures and reduce the risk of going out of specification when in operation.
