What is Clean Room Classification?

Clean room classification refers to the categorization of clean rooms based on the level of cleanliness and the number of airborne particles allowed in the environment. This classification is essential in industries such as pharmaceuticals, biotechnology, and Electronics, where contamination control is critical for product quality and safety.

The clean room classification system is typically defined by standards such as ISO 14644-1, which specifies the maximum allowable particle counts per cubic meter of air for different classes. For instance, a Class 100 Clean room allows no more than 100 particles of size 0.5 micrometers or larger per cubic foot of air. This rigorous classification ensures that clean rooms maintain the necessary conditions for sensitive processes, thereby protecting both products and personnel.

What is the FDA Classification of Clean Rooms?

The FDA classifies clean rooms primarily based on their role in manufacturing sterile pharmaceutical products, ensuring they meet stringent standards for cleanliness and contamination control. These classifications are often aligned with ISO standards, but with specific requirements for the pharmaceutical industry. Clean rooms used in drug manufacturing are categorized into different classes, such as Class 100, Class 10,000, and Class 100,000, based on the allowable concentration of particles per cubic foot of air. 

What is Clean Room Classification B?

1. High Cleanliness Control

Class b Clean Rooms maintain a stringent limit on particle contamination. For instance, they typically allow no more than 3,520 particles per cubic meter that are 0.5 microns or larger. This high level of cleanliness is essential for sensitive processes like drug manufacturing and sterile product preparation, where contamination could compromise both product quality and safety.

2. HEPA/ULPA Filtration

HEPA (High-Efficiency Particulate Air) or ULPA (Ultra-Low Penetration Air) filters are mandatory in Class b Clean Rooms. These filters efficiently capture fine particles, ensuring the air remains as free from contaminants as possible. HEPA and ULPA filters work to maintain Clean air and reduce the risk of microbial contamination in critical manufacturing areas.

3. Precise Temperature and Humidity Control

Class B clean rooms are typically equipped with precise temperature and humidity control systems to create stable environmental conditions. These systems are essential for maintaining optimal conditions for biological and chemical processes, ensuring that experiments or manufacturing processes proceed without disruptions due to environmental factors.

4. Strict Contamination Control Measures

In a Class B clean room, strict contamination control protocols are enforced. This includes controlled air pressure, gowning procedures, and thorough cleaning routines to prevent cross-contamination. Personnel are required to follow strict hygiene practices, and regular cleaning and maintenance schedules are established to ensure the environment remains contamination-free.

5. Compliance with Standards

Class B clean rooms are designed and operated according to international standards such as ISO 14644 and GMP (Good Manufacturing Practices). These standards provide guidelines for maintaining the required cleanliness levels and operational efficiency. Adherence to these regulations ensures that clean rooms meet both safety and regulatory requirements for high-risk industries.

What is ISO 9 clean room classification?

Cleanliness Standards of ISO 9：ISO 9 clean rooms are defined by the maximum allowable concentration of airborne particles. According to the iso 14644-1 standard, ISO 9 clean rooms can have up to 35,200,000 particles per cubic meter of air for particles that are 0.5 microns or larger. This makes it suitable for processes that do not require an ultra-clean environment but still need to limit contamination from airborne particulates.

ISO 9 clean rooms are often used in less sensitive industries where the risk of contamination is lower, such as in light manufacturing, packaging, or assembly processes. While they are not suitable for high-precision or sterile environments, they are effective for general production and operational activities that don't directly impact product quality.

Applications of ISO 9 Clean Rooms：ISO 9 clean rooms are often used in environments where contamination risks are moderate and where the production process does not involve highly sensitive products. Some common applications include:

• Assembly and packaging of non-sterile products.

• Light manufacturing processes that do not involve high-precision equipment or sensitive materials.

• Pharmaceutical packaging where sterility is not critical, but basic contamination control is still necessary.

• Food industry environments where a clean space is needed for general production activities, but not for sterile processing.

These clean rooms are ideal for general-purpose environments in industries where the primary goal is to control dust, dirt, and other large particulates, but where more rigorous controls are not necessary.

Airflow and Filtration in ISO 9: ISO 9 clean rooms typically use basic ventilation systems that employ HEPA (High-Efficiency Particulate Air) or ULPA (Ultra-Low Penetration Air) filters, although the filtration system does not need to be as high-efficiency as those used in higher-class clean rooms. The air exchange rate and the frequency of air changes per hour will vary depending on the specific requirements of the process being carried out. 

Regulatory Compliance: While ISO 9 does not require the same stringent conditions as higher classes, it still ensures that environments meet minimum cleanliness standards. It can be used in settings where compliance with Good Manufacturing Practices (GMP) is not as strict as for sterile product manufacturing. 

What is the Meaning of Clean Room Classification?

• CleanRoom Classification Overview

Cleanroom classification categorizes environments based on cleanliness levels and airborne particle limits, defined by standards like ISO 14644-1. Cleaner environments have stricter particle count allowances, essential for industries like pharmaceuticals, electronics, and aerospace.

• Purpose and Requirements

The main goal of cleanroom classification is to meet industry-specific needs for manufacturing or research. This includes particle limits and additional contamination controls, such as HEPA filtration and strict protocols, ensuring product protection and compliance with standards.
