What is ISO 14644-1:2015-Cleanrooms and associated controlled environments-Classification of air cleanliness by particle concentration?
ISO 14644-1:2015-Cleanrooms and associated controlled environments is an international standard that provides guidelines for the classification of air cleanliness in cleanrooms and controlled environments based on the concentration of airborne particles. Cleanrooms and controlled environments are used in various industries, such as pharmaceuticals, electronics manufacturing, and healthcare, where the presence of airborne particles can have a significant impact on product quality and process integrity.
Here’s an overview of the key aspects of ISO 14644-1:2015:
- Scope: The standard specifies the classification of air cleanliness in terms of the concentration of airborne particles in cleanrooms and controlled environments. It defines particle size ranges and limits for classification.
- Particle Size Classes: ISO 14644-1 classifies airborne particles based on their size, using specified particle size ranges from 0.1 micrometer to 5 micrometers. The standard divides particles into several size classes, typically represented as ISO class numbers (e.g., ISO Class 5, ISO Class 7, etc.).
- Cleanliness Classes: Each cleanliness class corresponds to a maximum allowable particle concentration for particles of a specified size range. For example, ISO Class 5 allows for a lower concentration of particles compared to ISO Class 7. The classification helps in defining the level of cleanliness required for a specific cleanroom or controlled environment.
- Sampling and Measurement: ISO 14644-1 provides guidance on how to sample and measure airborne particle concentrations to determine the cleanliness class. This includes specifying the number of sample locations, sampling duration, and the use of particle counters.
- Reporting: The standard also outlines the reporting requirements for documenting the results of particle concentration measurements. This includes specifying the particle size range being measured and the classification achieved.
And
- Maintenance and Monitoring: Cleanrooms and controlled environments need to be regularly monitored and maintained to ensure that they continue to meet the specified cleanliness class. ISO 14644-1 provides guidance on ongoing monitoring and maintenance procedures.
- Revision: It’s important to note that standards may be revised or updated over time. As of my last knowledge update in September 2021, ISO 14644-1:2015 was the most recent version. However, there may have been subsequent revisions or updates to the standard since then.
In summary, compliance with ISO 14644-1:2015 is crucial for industries where strict control of airborne particle contamination is essential to maintain product quality and ensure the safety of processes and products in cleanrooms and controlled environments.
Requirements of ISO 14644-1:2015-Cleanrooms and associated controlled environments
ISO 14644-1:2015-Cleanrooms and associated controlled environments specifies the requirements for the classification of air cleanliness in cleanrooms and controlled environments based on particle concentration.
Here are the key requirements outlined in the standard:
- Particle Size Ranges: ISO 14644-1 classifies airborne particles based on their size. The standard specifies discrete particle size ranges from 0.1 micrometer to 5 micrometers. These size ranges are used to determine the maximum allowable particle concentrations for each cleanliness class.
- Cleanliness Classes: The standard defines cleanliness classes (commonly referred to as ISO classes) that correspond to different levels of particle contamination. Each cleanliness class is denoted by a specified maximum allowable particle concentration for each particle size range. The cleanliness classes typically range from ISO Class 1 (the cleanest) to ISO Class 9 (the least clean).
- Sampling Locations: ISO 14644-1 provides guidance on the number and location of sampling points within the cleanroom or controlled environment. The standard suggests a grid-based approach for selecting sampling locations to ensure representative measurements.
- Sampling Duration: The standard outlines the recommended duration for particle concentration measurements. Typically, measurements are taken during periods of stable operations and should be of sufficient duration to obtain statistically meaningful results.
- Particle Counting Equipment: ISO 14644-1 specifies the requirements for particle counting equipment used for measuring airborne particle concentrations. This includes requirements for instrument calibration and validation to ensure accurate and reliable measurements.
- Calculation of Cleanliness Class: Cleanliness classes are determined by comparing the measured particle concentrations in each size range to the specified limits for the desired class. To achieve a specific cleanliness class, the particle concentration in each size range must not exceed the corresponding limit.
Also
- Reporting: The standard requires the documentation of particle concentration measurements, including the cleanliness class achieved and the results for each particle size range. This documentation serves as a record of the cleanroom’s performance.
- Maintenance and Monitoring: Cleanrooms and controlled environments must be regularly monitored and maintained to ensure they continue to meet the specified cleanliness class. ISO 14644-1 provides guidance on ongoing monitoring and maintenance procedures.
- Revision and Updates: Users of the standard should be aware of any revisions or updates to ISO 14644-1 that may occur over time. Staying informed about the latest version of the standard is important for compliance.
It’s important to note that ISO 14644-1:2015 is just one part of a series of ISO standards that address cleanrooms and controlled environments. Other parts of the ISO 14644 series cover topics such as testing and monitoring cleanrooms, cleanroom design and construction, and cleanroom operations.
