ISO 14644 Standards were first formed from the US Federal Standard 209E Airborne Particulate Cleanliness Classes in Cleanrooms and Clean Zones. The need for a single standard for cleanroom classification and testing was long felt. After ANSI and IEST petitioned to ISO for new standards, the first document of ISO 14644 was published in 1999, ISO 14644-1.
ISO 14644-1 covers the classification of air cleanliness in cleanrooms and associated controlled environments. Classification in accordance with this standard is specified and accomplished exclusively in terms of concentration of airborne particulates. The document was submitted as an American National Standard and has been adopted as ANSI/IEST/ISO 14644-1:1999 in the United States, following the cancellation of FED-STD-209E.
Part 2 specifies requirements for periodic testing of a cleanroom or clean zone to prove its continued compliance with ISO 14644-1 for the designated classification of airborne particulate cleanliness. It also specifies requirements for the monitoring of a cleanroom or clean zone (installation) to provide evidence of its continued compliance with ISO 14644-1 for the designated classification of airborne particulate cleanliness. It became an International Standard following the cancellation of FED-STD-209E. In the United States in 2000 it was adopted as ANSI/IEST/ISO 14644-2:2000.
This part specifies test methods for designated classification of airborne particulate cleanliness and for characterizing the performance of cleanrooms and clean zones. These test methods are specified in the document for two different types of cleanrooms and clean zones; unidirectional flow and nonunidirectional flow.
The most important objectives of this highly referenced document are to provide an internationally common basis of measurement and evaluation of cleanrooms and, at the same time, not to prevent the introduction of new technologies.
This part specifies requirements for the design and construction of cleanroom and clean air devices, as well as requirements for start-up and qualification, but does not prescribe specific technological nor contractual means to meet the requirements. This document is intended for purchasers, suppliers, and designers of cleanroom installations. It was submitted as an American National Standard in 2001.
ISO 14644-5 provides the basic requirements for operating and maintaining cleanrooms and associated controlled environments. This standard addresses requirements that are basic to the operation of all cleanrooms, regardless of the application. Topics include:
This part was published as an International Standard in 2004. The document was submitted as an American National Standard and has been adopted as ANSI/IEST/ISO 14644-5:2004 in the United States.
This part is an important document for any contamination control professional. This document describes all the terms and definitions in ISO 14644 and ISO 14698. In March 2008 this ISO Standard recently became an American National Standard.
This part of ISO 14644 specifies the minimum requirements for the design, construction, installation, testing and approval of separative devices in those respects where they differ from cleanrooms as described in Parts 4 and 5. Separative devices range from open to closed systems.
The limitations are:
This part was published as an International Standard in 2004. The document was submitted as an American National Standard and has been adopted as ANSI/IEST/ISO 14644-7:2004.
This part of ISO 14644 covers the classification of airborne molecular contamination (AMC) in cleanrooms and associated controlled environments, in terms of airborne concentrations of specific chemical substances (individual, group or category) and provides a protocol to include test methods, analysis and time-weighted factors within the specification for classification.
This document became a Standard in 2006. It was developed by the Secretariat of ISO Technical Committee 209, IEST.
This ISO document describes the classification of the particle contamination levels on solid surfaces in cleanrooms and associated controlled environments applications. Recommendations on testing and measuring methods as well as information about surface characteristics are given in informative annexes.
It is currently a Committee Draft and is not yet available as a Standard.
A cleanroom or clean room is a facility ordinarily utilized as a part of specialized industrial production or scientific research, including the manufacture of pharmaceutical items and microprocessors. Cleanrooms are designed to maintain extremely low levels of particulates, such as dust, airborne organisms, or vaporized particles. Cleanrooms typically have an cleanliness level quantified by the number of particles per cubic meter at a predetermined molecule measure. The ambient outdoor air in a typical urban area contains 35,000,000 particles for each cubic meter in the size range 0.5 μm and bigger in measurement, equivalent to an ISO 9 cleanroom, while by comparison an ISO 1 cleanroom permits no particles in that size range and just 12 particles for each cubic meter of 0.3 μm and smaller.Cleanroom suitability
Cleanroom suitability describes the suitability of a machine, operating utility, material, etc. for use in a cleanroom, where air cleanliness and other parameters are controlled by way of technical regulations in accordance with ISO 14644.Cleanroom suitability is a subdomain of cleanliness suitability and primarily describes the particle emission behavior of a machine or operating utility (test piece).Institute of Environmental Sciences and Technology
The Institute of Environmental Sciences and Technology (IEST) is a non-profit, technical society. Information on ISO 14644 and ISO 14698 standards can be found through this organization.
Founded in 1953, the organization is headquartered in Schaumburg, Illinois. Its members are internationally recognized in the fields of environmental tests; contamination control; product reliability; and aerospace.Kennedy Space Center
The John F. Kennedy Space Center (KSC, originally known as the NASA Launch Operations Center) is one of ten National Aeronautics and Space Administration field centers. Since December 1968, Kennedy Space Center has been NASA's primary launch center of human spaceflight. Launch operations for the Apollo, Skylab and Space Shuttle programs were carried out from Kennedy Space Center Launch Complex 39 and managed by KSC. Located on the east coast of Florida, KSC is adjacent to Cape Canaveral Air Force Station (CCAFS). The management of the two entities work very closely together, share resources, and even own facilities on each other's property.
Though the first Apollo flights, and all Project Mercury and Project Gemini flights took off from CCAFS, the launches were managed by KSC and its previous organization, the Launch Operations Directorate. Starting with the fourth Gemini mission, the NASA launch control center in Florida (Mercury Control Center, later the Launch Control Center) began handing off control of the vehicle to the Mission Control Center shortly after liftoff; in prior missions it held control throughout the entire mission.Additionally, the center manages launch of robotic and commercial crew missions and researches food production and In-Situ Resource Utilization for off-Earth exploration. Since 2010, the center has worked to become a multi-user spaceport through industry partnerships, even adding a new launch pad (LC-39C) in 2015.
There are about 700 facilities and buildings grouped across the center's 144,000 acres. Among the unique facilities at KSC are the 525 ft tall Vehicle Assembly Building for stacking NASA's largest rockets, the Launch Control Center - which conducts space launches at KSC, the Operations and Checkout Building, which houses the astronauts dormitories and suit-up area, a Space Station factory, and a 3-mile-long Shuttle Landing Facility. There is also a Visitor Complex open to the public on site.List of International Organization for Standardization standards, 14000-14999
