Standard Practice for Cleaning and Maintaining Controlled Areas and Clean Rooms

Standard Practice for Cleaning and Maintaining Controlled Areas and Clean Rooms

SIGNIFICANCE AND USE
4.1 This practice identifies methods for cleaning and maintaining controlled areas and clean rooms as defined by ISO 14644-1 and ISO 14644-2. Cleaning procedures are described, and cleaning frequency for different classes of facility are given. Compliance with this practice will make it easier and more likely that the required level of facility cleanliness will be maintained. A cleaner facility also will help to protect flight hardware from contamination and should reduce the frequency for cleaning flight hardware. This practice does not discuss operation and operational procedures for cleanrooms and controlled areas. Other documents such as IEST-RP-CC026 and Practice E2352 provide recommended practices for operating cleanrooms and controlled areas.
SCOPE
1.1 This practice covers the procedures to be followed for the initial cleaning and normal maintenance of cleanrooms and controlled areas. This practice is applicable to aerospace clean areas where both particles and molecular films (NVR) must be controlled.  
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in non-conformance with the standard.  
1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.

ASTM E2090-12(2020)(Test Method)
Standard Test Method for Size-Differentiated Counting of Particles and Fibers Released from Cleanroom Wipers Using Optical and Scanning Electron Microscopy

SIGNIFICANCE AND USE
5.1 This test method provides for accurate and reproducible enumeration of particles and fibers released from a wiper immersed in a cleaning solution with moderate mechanical stress applied. When performed correctly, this counting test method is sensitive enough to quantify very low levels of total particle and fiber burden. The results are accurate and not influenced by artifact or particle size limitations. A further advantage to this technique is that it allows for morphological as well as X-ray analysis of individual particles.
SCOPE
1.1 This test method covers testing all wipers used in cleanrooms and other controlled environments for characteristics related to particulate cleanliness.  
1.2 This test method includes the use of computer-based image analysis and counting hardware and software for the counting of densely particle-laden filters (see 7.7 – 7.9). While the use of this equipment is not absolutely necessary, it is strongly recommended to enhance the accuracy, speed, and consistency of counting.  
1.3 The values stated in SI units are to be regarded as the standard.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.

ASTM E2614-15(2020)e1(Guide)
Standard Guide for Evaluation of Cleanroom Disinfectants

SIGNIFICANCE AND USE
5.1 Requirements for aseptic processing areas include readily cleanable floors, walls, and ceilings that have smooth, non-porous surfaces; particle, temperature, and humidity controls; and cleaning and disinfecting procedures to produce and maintain aseptic conditions. These controls, combined with careful and thorough evaluation of the chemical agents used for the cleaning and disinfection program, should lead to achieving the specified cleanliness standards and control of microbial contamination of products. Qualification of disinfectants in pharmaceutical, biotechnology, medical device facilities, and associated controlled environments, along with validation of the cleaning and disinfection process, is subject to scrutiny by regulatory agencies.  
5.2 An effective cleaning and disinfection program in aseptic processing areas of a Good Manufacturing Practice (GMP) - regulated facility is critical to assure product quality. Manufacturers are held to a high standard when it comes to product sterility, and regulatory agencies increasingly request validation data to support sanitization and disinfection procedures. Regulatory authorities expect evidence of the effectiveness of disinfection agents against environmental microorganisms isolated from the facility. The FDA Guideline for Aseptic Processing states, “The suitability, efficacy, and limitations of disinfecting agents and procedures should be assessed. The effectiveness of these disinfectants and procedures should be measured by their ability to ensure that potential contaminants are adequately removed from surfaces.”7  
5.3 Basic knowledge regarding the effectiveness of different chemical agents against vegetative bacteria, fungi, and spores will aid in selecting chemical agents.  
5.4 An understanding of test methods used to assess disinfectant effectiveness is important. Most methods are adaptable, allowing the user to customize the methods to their specific requirements.
SCOPE
1.1 This guide identifies important factors to consider when selecting a disinfectant for use in a cleanroom or similar controlled environment and recommends test methods suitable for evaluating disinfectants. The proper selection of disinfecting agent combined with qualification testing is a key element of a successful disinfection program. Regulatory guidance such as United States Pharmacopoeia Chapter , “Disinfectants and Antiseptics” and the FDA Guidance for Industry, “Sterile Drug Products Produced by Aseptic Processing–Current Good Manufacturing Practice” address the necessity of disinfectant effectiveness testing but do not clearly define acceptable test methods.  
1.2 An understanding of microbiology and microbiological techniques is essential. Knowledge in the following areas is recommended: microorganisms, antimicrobial products (disinfectants, sporicides, and decontamination agents), the chemistry of disinfection, mechanism of activity of disinfectants on cells, application procedures, cleanroom surfaces, and environmental conditions within a cleanroom. This information is available in several published texts listed in the bibliography.  
1.3 The theoretical basis for disinfectant activity is not addressed in this guide. An understanding of the effect of disinfectant concentration on microbial reduction (concentration exponent) and kinetics is desirable in determining the use-dilution of different disinfectants and in using dilution to neutralize a disinfectant for efficacy testing. USP chapter  provides further information on this topic.  
1.4 This guide is written for the cleanroom environment, although many of the principles outlined in this standard are applicable to manufacturing and processing environments outside of the cleanroom.  
1.5 Evaluation of disinfectants for biofilm control is outside the scope of this document.

ASTM D5141-23(Test Method)
Standard Test Method for Determining Filtering Efficiency and Flow Rate of the Filtration Component of a Sediment Retention Device

SIGNIFICANCE AND USE
5.1 This test method is used to determine the filtering efficiency and flow rate of the filtration component of a sediment retention device, such as a silt fence, a silt barrier, or a silt curtain, for specific soil tested.  
5.2 This test method may be used for the design of the filtration component of a sediment retention device to meet requirements of regulatory agencies in filtering efficiency or flow rate for the specific soil tested.  
5.2.1 The designer can use this test method to determine the spacing between sediment retention devices.  
5.3 This test method is intended for performance evaluation, as the results will depend on the specific soil evaluated. Unless testing with the default soil is desired, it is recommended that the user or representative perform the test to pre-approve products, as sediment retention device manufacturers are not typically equipped to handle or test soil requirements.  
5.4 This test method provides a means of evaluating the filtration component of sediment retention devices with different soils under various conditions that simulate the conditions that exist in a sediment retention device installation. This test method may be used to simulate several storm events on the same sediment retention device specimen. Therefore, the number of times this test is repeated per specimen is dependent upon the user and the site conditions.
SCOPE
1.1 This test method is used to determine the filtering efficiency and the flow rate of the filtration component of a sediment retention device, such as a silt fence, silt barrier, or inlet protector.  
1.1.1 The results are shown as a percentage for filtering efficiency and cubic metres per square metre per minute (m3/m2/min) or gallons per square foot per minute (gal/ft2/min) for flow rate.  
1.1.2 The filtering efficiency indicates the percent of sediment removed from sediment-laden water.  
1.1.3 The flow rate is the average rate of passage of the sediment-laden water through the filtration component of a sediment retention device.  
1.2 This test method requires several specialized pieces of equipment, such as an integrated water sampler and an analytical balance, or a vacuum filtration system. At the client’s discretion, the test soil is either a site-specific soil or a soil that is representative of a target default gradation.  
1.3 The values stated in SI units are the standard, while the inch-pound units are provided for information. The values expressed in each system may not be exact equivalents; therefore, each system must be used independently of the other, without combining values in any way.  
1.4 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use.  
1.5 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
