Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www.iso.org/patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO's adherence to
the World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT), see

This document was prepared by Technical Committee ISO/TC 209, Cleanrooms and associated controlled
environments, in collaboration with the European Committee for Standardization (CEN) Technical
Committee CEN/TC 243, Cleanroom technology, in accordance with the Agreement on technical
cooperation between ISO and CEN (Vienna Agreement).
This second edition cancels and replaces the first edition (ISO 14644-9:2012), of which it constitutes a
minor revision. The changes are as follows:
— "Class" (classification, classified) has been changed to grade or assessment where appropriate;
— ISO 14644-6 has been removed from the opening text of Clause 3 and, as a result, Clause 2;
— entry 3.8 removed from Clause 3;
— ISO 4287 and ISO 4288 replaced by ISO 21920-2 and ISO 21920-3, respectively;
— ISO 16232-2, ISO 16232-3, ISO 16232-4 and ISO 16232-5 replaced by ISO 16232;
— minor editorial changes.

Introduction
Cleanrooms and associated controlled environments provide for the control of contamination to levels
appropriate for accomplishing contamination-sensitive activities. Products and processes that benefit
from the control of contamination include those in such industries as aerospace, microelectronics,
optics, nuclear and life sciences (pharmaceuticals, medical devices, food, healthcare).
ISO 14644-1 to ISO 14644-8, ISO 14698-1 and ISO 14698-2 deal exclusively with airborne particle
and chemical contamination. Many factors, besides the assessment of surface cleanliness, should
be considered in the design, specification, operation and control of cleanrooms and other controlled
environments. These factors are covered in some detail in other parts of ISO 14644 and ISO 14698.
This document provides an analytical process for the determination and designation of surface
cleanliness levels based on particle concentration. This document also lists some methods of testing, as
well as procedure(s) for determining the concentration of particles on surfaces.
