The cleanroom classification standards FS E and ISO require specific particle count measurements and calculations to classify the cleanliness level of a cleanroom or clean area. This paper compares the requirements of the two cleanroom classification standards and the implementation of the standard calculations in Particle Vision PortAll software from Pacific Scientific Instruments. Using measurement data from Met One or Royco particle counter instruments, the PortAll software can automatically generate cleanroom classification results.
Airborne Particulate Cleanliness Class Comparison. Airborne Particulate Cleanliness Classes. Required Testing. Optional Testing. Classifying a Cleanroom. ISO Cleanroom Standards. Federal Standard E has long been the only definition of cleanroom classification levels available from a standards organization. General Service Administration and approved for use by all U.
In the absence of an international standard, FS E was broadly used internationally. The need for a new international standard that covered more cleanroom environmental parameters and practices led to the formation of a technical committee of the International Standards Organization. The goal of TC is "standardization of equipment, facilities, and operational methods for cleanrooms and associated controlled environments.
This includes procedural limits, operational limits and testing procedures to achieve desired attributes to minimize micro contamination. This ISO committee will produce 10 new standards documents that relate to cleanrooms or clean zones described below. The first two standards have been published: ISO and The first document, ISO , Cleanrooms and associated controlled environments Part 1: Classification of airborne particulates has been released as a final draft international standard FDIS.
The second document, ISO , Cleanrooms and associated controlled environments Part 2: Testing and monitoring to prove continued compliance with ISO ; has been released as a draft international standard DIS. Both are legal for use in trade. It is expected that E will be in use in some industries through the next five years, but that eventually it will be replaced globally by ISO Particle Vision PortAll software performs the cleanroom classification calculations for airborne particulate levels required by both of the U.
The actual text of the standards must be ordered from the appropriate standards organization see Sources and Links. This paper gives a general overview of the required particle count measurements given in the standards. Return to contents. The cleanliness classification levels defined by FSE and ISO are approximately equal, except the new ISO standard uses new class designations, a metric measure of air volume and adds three additional classes - two cleaner than Class 10 and one beyond than Class , ISO The precise count levels required by ISO for each classification, by particle size, are given below.
Airborne Particulate Cleanliness Classes by cubic meter. ISO determines the type and frequency of testing required to conform with the standard. The following tables indicate which tests are mandatory and which tests are optional. Required Testing ISO Schedule of Tests to Demonstrate Continuing Compliance. Optional Testing ISO Schedule of Additional Optional Tests. There are three basic steps to classifying a cleanroom using a particle counter and Particle Vision PortAll software:. PortAll software automatically performs the calculations and gives the results.
All you have to do is collect the sample data. C n,m is the class limit in number of particles per cubic meter for a given particle size. Note: if you intend to calculate the class level at multiple particle sizes, be sure to select a sample volume for the largest size, which is also the largest required volume. This will ensure the sample data is valid for all sizes.
There is no definition of the number of samples to be taken at each sample point except in the case when there is only one sample point. For one sample point, there must be at least three sample volumes taken. Note: PortAll software requires at least two locations to perform classification calculations, making the last requirement irrelavent. Select the sample count values to be used in the classification calculation. The classification level can only be calculated for one particle size at a time.
Click the ISO calculator icon to perform the classification calculations. The resulting classification for the selected particle size is displayed at the bottom of the sample data for that size column on the spreadsheet. Per the ISO standard, if the number of sample locations is greater than 10 and more than one sample was collected per location, then the classification is determined by the averages of the particle counts obtained at each location.
The calculated average at each location must pass the classification limit. If the number of sample locations is at least two but not more than nine, then the Upper Confidence Limit [UCL] will also be calculated, and the calculated value for the UCL must also be less than the classification limit. Click the FS calculator icon to perform the classification calculations. Per the FSE standard, if the number of sample locations is greater than 10 and more than one sample was collected per location, then the classification is determined by the averages of the particle counts obtained at each location.
Once you have selected the count values in the spreadsheet for the particle size you want used for the classification calculation, PortAll calculates the class as follows:. PortAll searches the unselected region of the spreadsheet and determines the number of sample locations involved. The software then sorts the samples by location and determines the average count value per location.
The highest average count value is determined and this value is compared to the standard table to determine the classification. If there are between two and nine locations, PortAll also calculates the UCL and compares the result to the standard table. The UCL result and average count result are compared and the worst classification is chosen. The following four rules must be followed to ensure an accurate classification result from PortAll.
This ensures that the PortAll spreadsheet of the instrument memory will only contain relevant samples, making it easier to select which data should be used for the classification calculations. In , at the urging of the Institute of Environmental Sciences, the American National Standards Institute petitioned ISO to create a technical committee on cleanrooms and associated controlled environments.
Its mission is to develop an international standard for cleanrooms and associated controlled environments that encompasses the standardization of equipment, facilities, and operational methods, while also defining procedural and operational limits and testing procedures to minimize contamination. These first ISO cleanroom standards are two of 10 documents see table A that will make up the new family of global cleanroom standards.
Many of these documents are at the final voting stage and can be legally used in trade. ISO Document. Classification in accordance with this standard is specified and accomplished exclusively in terms of concentration of airborne particles. These requirements invoke the test described in ISO for the classification of the cleanroom or clean zone. Additional tests are also specified, to be carried out based on the requirements of this International Standard.
This document describes the necessary performance tests for various types of cleanrooms. The occupancy states of "as built", "at rest", and "in operation" are defined as well as appropriate levels of certification. A large index is provided on a variety of test methods and appropriate equipment. This document will be a primer on the design and construction of cleanrooms.
It will cover all aspects of the process from design development to startup and commissioning. This document will be a primer on cleanroom operation. It will cover all aspects of the operation of a cleanroom including entry and exit procedures for equipment and personnel, education and training, cleanroom apparel, and facility issues such as maintenance, housekeeping, monitoring, system failure, etc. This document will provide a consistent reference for all terms, definitions and units discussed across all ISO cleanroom standards.
This document will focus on specialized stand-alone clean spaces including their design, construction, and operations. This will be a new document covering measurement of airborne molecular contamination in clean zones. The first meeting is scheduled for December This document describes principles and basic methodology for a formal system to assess and control biocontamination where cleanroom technology is applied.
This document describes basic principles and methodology for microbiological data evaluation. It provides a method of estimating of biocontamination from sampling for viable particles in zones at risk. ISO , "Classification of Air Cleanliness" Three new classes have been added to the existing standard, Federal Standard , two cleaner and one dirtier.
ISO covers specifications for testing and monitoring. This document specifies the requirements for monitoring a cleanroom or clean zone to provide evidence of its continued compliance with ISO for the designated classification of airborne particulate cleanliness. A schedule of normative and informative tests is included in the document.

Долевая собственность: преимущества и недостатки
В сентябре года вступил в силу международный стандарт ISO Ранее некоторым организациям приходилось искусственно разрабатывать документацию, которая не несла для компании никакой ценности и была создана исключительно для того, чтобы соответствовать требованиям предыдущей версии стандарта ГОСТ ISO ISO Теперь организация не обязана разрабатывать Руководство по качеству, 6 обязательных документированных процедур, а ограничится, документами необходимыми с ее точки зрения для успешного функционирования системы менеджмента качества. Часто до этого в организациях, внедривших систему менеджмента качества возникала путаница в том, что является документом, а что записью например, договора, чертежи.

Partner: Antarpreet Jutla, West Virginia University Project dates: December - May Project Overview: Research planned in this proposal looks into science-practice interactions on environmental issues. In the current context, most of the climate-related studies in Central Asia are focused on water quantity impacts and their implications for transboundary water allocation in the region. The main objective of this PEER project is to assess the impacts of climate change on surface water quality of the Amu Darya River and develop a "climate change - water quality" model that will provide much needed information to decision makers for elaboration of possible adaptation actions. Even though it is within the mandate of transboundary organizations, such as the river basin management organization BVO Amudarya, the issue of water quality in the basin is currently neglected due to the absence of relevant information and data in the region, as well as the lack of the capacity to investigate the issue. A special focus will be to build the capacity of BVO Amudarya in terms of water quality maintenance. The project should also help to raise awareness of states and key stakeholders on climate change impacts on water quality. A series of policy dialogues among policy makers that share water in the Amu Darya Basin will be organized to share results of the study. During the past quarter, project team members started the statistical analysis of hydrological, climate and water quality data in order to establish a relationship between water quality and climate indicators. During the process, the team realized there were gaps in data from other countries such as Tajikistan and Turkmenistan. Therefore, two specialists were recruited to collect the missing data.
