What is ISO 8 cleanroom classification?

An ISO -1 classified cleanroom is a room or contained environment where it is crucial to keep particle counts low. Typically, these particles are dust, airborne microbes, aerosol particles, and chemical vapors. Beyond particle counts, cleanrooms often have controls for a number of other parameters like pressure, temperature, and humidity. Additionally, to be considered a cleanroom, the space needs High-Efficiency Particulate Air (HEPA) filters to remove particles from the air.

ISO -1 Cleanrooms are classified from ISO 1 to ISO 9. Each cleanroom class is denoted by a maximum concentration of particles per cubic meter or cubic foot of air. ISO 8 is the second lowest cleanroom classification.

ISO 8 Cleanroom Standards

The allowed particle counts for an ISO 8 cleanroom depend on the referenced standard and its measurements. According to US Federal Standard 209E, ISO 8 cleanrooms are also known as Class 100,000 cleanrooms.

-08-10 ISO Cleanroom Standards

ISO -1 replaced the federal standard and states that an ISO 8 cleanroom needs less than 3,520,000 of &#; 0.5 micron sized particles per cubic meter of air. Only particles 0.5 microns or larger are measured in an ISO 8 cleanroom. This is done because the concentration of smaller particle sizes is too high.

ISO 8 Protective Requirements and Design Considerations

Designing a cleanroom requires taking additional regulatory standards and requirements into account based on industry and application. However, there are several general requirements and environmental parameters to consider for an ISO 8 cleanroom. For an ISO 8 Cleanroom, these include:

• HEPA filtration
• Air Changes per Hour (ACH)
• Air pressure
• Temperature and humidity
• Amount of personnel working in the space
• Static control
• Lighting
• Noise levels

Since an ISO 8 cleanroom is focused on measuring particles 0.5 microns or larger, the HEPA filtration system needs to be 99.97% efficient and a minimum of 20 air changes per hour is recommended. The final filtration of air occurs where the air enters the cleanroom. Additionally, it is most common for ISO 8 cleanrooms to employ non-unidirectional or mixed air flow patterns with low wall air returns. Common ISO 8 Applications

A wide variety of industries and applications have cleanrooms. Some of the most common with ISO 8 cleanrooms include:

Frequently Asked Questions on ISO 8

What is the difference between ISO 7 and ISO 8?

The two main differences between ISO 7 and ISO 8 cleanrooms are particle count and ACH requirements, which set them apart for differing applications. An ISO 7 cleanroom must have 352,000 particles &#; 0.5 microns per cubic meter and 60 ACH per hour as opposed to ISO 8&#;s 3,520,000 particles and 20 ACH.

When is a cleanroom required?

 

A cleanroom can be used for a number of industries and applications. They are required for spaces where cleanliness and sterility are crucial. For context, an ISO 8 cleanroom is usually 5-10 times cleaner than a typical office environment. Specifically, in medical device and pharmaceutical manufacturing cleanrooms, the safety and quality of products is of the utmost importance, and raw materials, manufacturing processes, and finished product and can be affected if too many particles enter the space.

Setra's CEMS for Cleanroom Environmental Monitoring

An environmental monitoring system is designed to gather, analyze, and notify on detailed cleanroom environmental data. For manufacturing spaces in particular, the goal of cleanroom monitoring is to assess the potential contamination risk of the product and remain in compliance with regulatory standards.

CEMS is Setra&#;s continuous environmental monitoring software that collects real-time data from in room cleanroom measurement sensors. Setra&#;s CEMS is a single system that can monitor a diverse facility with multiple locations, providing instant environmental data access and sophisticated analysis from a web-based interface accessible from any internet enables device. Real-time alarm notifications can be seen visually in software and sent to users via text message and . Instant, up-to-date reports and graphs provide easy access to proper documentation for regulatory requirements. Setra&#;s CEMS helps to continuously monitor an environment during the manufacturing process to simplify operations, minimize the risk of contamination, and improve the quality of products.

With simple networking and dependable remote access via the secure SetraCLOUD, users can save time and money with data exports and reporting features.

 

There are 9 ISO classifications, ISO 1, ISO 2, ISO 3, ISO 4, ISO 5, ISO 6, ISO 7, ISO 8, and ISO 9. ISO 1&#;

What Is A Cleanroom?

A cleanroom is a controlled space where the number, concentration and size of airborne particles are classified and tightly maintained to create a sterile environment. 

There are 9 ISO classifications, ISO 1, ISO 2, ISO 3, ISO 4, ISO 5, ISO 6, ISO 7, ISO 8, and ISO 9. ISO 1 is considered the cleanest while ISO 9 is considered the dirtiest. The table refers to the concentration of particles in a 1 cubic meter sample according to particle size as a micrometer or micron μm.

Table 1 of the ISO-1: shows each classes maximum limit of air cleanliness by particle concentration.

What is an ISO 8 Cleanroom?

Before choosing an ISO classification, determine what size and number of particles can negatively affect your experiment, procedure or process.

An ISO 8 cleanroom has to go through the ISO 9 classification first. An ISO 8 classification requires that the air contain less than 3 520 000 particles >0.5 micron per cubic meter, less than 293,000 >5 micron per cubic meter. In order to achieve this you will need a series of filters for example a G4 and a H15 and it is recommended that you dilute the particulate levels by achieving a complete air change rate of up to 60 air changes per hour.

Why Do You Need an ISO 8 Cleanroom?

ISO 8 cleanrooms are used to protect products and procedures that are sensitive to a particular size and number amount of particle size. Industries that might require this level of cleanroom include aerospace, automotive, aviation, chemicals, defence, digital, technology and computer services, pharmaceutical, electronics, machinery and parts, life sciences, oil and gas production, research and innovation, space and lots more.

How To Get an ISO 8 Cleanroom?

One of the main design differences between an ISO 8 cleanroom and other, cleaner classes is that the ISO 8 Cleanroom does not require an airlock. However we usually advise you do still use an airlock for gowning as it aids your SOP and compliance. It uses a non-unidirectional airflow and goes through up to 60 air changes per hour.

How to Maintain an ISO 8 Cleanroom?

ISO 8 Cleanroom requires extensive care and maintenance. This is usually done with:

• Constant Positive Pressure
• Careful Material Selection
• All Personnel wearing PPE
• Air Filtration and Dilution

Do&#;s and Don&#;ts Inside a Cleanroom

• Do wipe all surfaces regularly to remove contamination. This should form an integral part of your SOP.
• Do keep all doors closed to maintain positive pressure.
• Do clean everything that&#;s being brought inside the cleanroom
• Do make sure all personnel wear personal protective equipment (PPE) over their clothes before going inside the cleanroom
• Don&#;t bring unnecessary objects inside the cleanroom. It is more for you to clean and reduces air flow.
• Don&#;t bring shedding materials into the cleanroom eg cardboard and natural fabrics.
• Don&#;t eat or drink in your cleanroom.
• Don&#;t turn the filtration off. This breaks the protocol as particulate can now enter your environment. You must maintain positive pressure.
