ISO Class 5 Clean Room

The ISO 14644-1 standard defines particle count requirements for cleanrooms based on their classification. An ISO Class 5 cleanroom is among the most stringent classifications, allowing a very limited number of particles to remain in the air.

  • Maximum Particle Counts:

    ≤ 3,520 particles/m³ for 0.5 µm and larger

    ≤ 29 particles/m³ for 5.0 µm and larger

  • Air Changes per Hour (ACH): 240-480 ACH

  • Airflow Type: Unidirectional (laminar) airflow

  • Filtration: HEPA or ULPA filters with ≥99.97% efficiency for 0.3 µm particles

  • Pressure: Positive pressure relative to surrounding areas

  • Temperature and Humidity: Typically 18°C-22°C and 40%-60% relative humidity (may vary depending on the application)

ISO Class 5 Clean Room Video Introduction

FAQ

What is ISO class 5 PEC?

ISO Class 5 PEC refers to a Primary Engineering Control (PEC) that is designed to provide an ultra-clean, controlled environment, typically for critical processes that require ISO Class 5 cleanliness levels. ISO Class 5 is one of the highest levels of cleanroom classification, corresponding to 3,520 particles per cubic meter (for particles ≥0.5 microns) under the ISO 14644-1 standard. PEC is often used in industries where contamination control is crucial, such as pharmaceutical manufacturing, biotechnology, and medical device production.

What is the particle count for lSO Class 5 cleanroom?

An ISO Class 5 softwall cleanroom is defined by the ISO 14644-1 standard, which specifies the maximum allowable concentration of airborne particles in a given volume of air. For an ISO Class 5 cleanroom, the maximum particle count for particles ≥ 0.5 microns in size is:3,520 particles per cubic meter (or 100 particles per cubic foot).

What is the difference between lSO 5 and Grade A?

These two clean room grade standards are the same in terms of the number of clean dust particles, but they are different standard series. ISO5 is the internationally used clean room grade standard, and Class A is the clean room grade standard for the GMP pharmaceutical industry.

What is the filter coverage of lSO 5?

The filter coverage of an ISO Class 5 cleanroom refers to the area of the cleanroom that is covered by air filtration systems (typically HEPA filters or ULPA filters) to maintain the required cleanliness levels. The objective of these filtration systems is to control airborne particle contamination and ensure that the particle count in the room meets the ISO Class 5 standard, which limits particles ≥ 0.5 microns to no more than 3,520 particles per cubic meter (or 100 particles per cubic foot).

What is lSO class 5 cleanroom?

An ISO softwall 5 cleanroom is a highly controlled environment defined by the ISO 14644-1 standard. It is designed to maintain extremely low levels of airborne particulate contamination, with strict limits on the number of particles in the air. Cleanrooms like ISO Class 5 are used in industries where even minimal contamination can lead to defects, failures, or safety risks.

What is lSO in clean room?

ISO in the context of cleanrooms refers to the International Organization for Standardization (ISO), which sets global standards for a wide range of systems, processes, and products. Specifically, ISO 14644-1 is the standard that governs the classification of cleanrooms and controlled environments based on their level of airborne particulate contamination.

Show to ISO Class 5 Cleanroom Design and Build?

Designing and building an ISO Class 5 cleanroom involves a series of steps to ensure it meets the stringent standards of cleanliness required by ISO 14644-1,Cleanroom Design Components,Airflow and Filtration System,Cleanroom Construction Materials,Air Handling and HVAC System,Personnel Flow and Gowning Procedures,Environmental Monitoring and Control,Testing and Validation,Before the cleanroom can be used, it must undergo a qualification and validation process to ensure it meets the ISO Class 5 standards. This includes:

What are the applications of ISO Class 5 cleanrooms?

Here are some industries and specific processes where an ISO 5 cleanroom is essential:

1. Pharmaceutical Manufacturing

2. Semiconductor and Electronics Manufacturing

3. Biotechnology and Cell Culture

4. Medical Device cleanroom Manufacturing

5. Aerospace and Precision Engineering

6. Food and Beverage Processing (Specialized)

7. Research and Development (R&D) Laboratories

What are the Clean Room Classifications?

Cleanroom classifications are defined by the **ISO 14644-1** standard based on the maximum allowable concentration of airborne particles of a specified size, ranging from **ISO Class 1** (the cleanest, with no more than 1 particle per cubic meter) to **ISO Class 9** (the least clean, allowing up to 35 million particles per cubic meter).

What is the relationship ISO Class 5 Cleanrooms and IFed-Std 209E Class 100 relation?

ISO Class 5 cleanrooms and FED-STD-209E Class 100 both refer to highly controlled environments with stringent particle contamination limits, but they are based on different standards. ISO 5 cleanroom, defined by ISO 14644-1, allows no more than 3,520 particles per cubic meter (0.5 microns). In comparison, FED-STD-209E Class 100, a previous U.S. federal standard, specifies 100 particles per cubic foot (roughly 3,520 particles per cubic meter) for particles 0.5 microns. Essentially, ISO Class 5 and Class 100 are equivalent in terms of the particle count limit, but ISO 14644-1 (ISO Class 5) has become the global standard, while FED-STD-209E was replaced by ISO standards in 2001.

What ls lsO 8, IS0 7, IS0 6, 1S0 5 Cleanroom?

ISO 8, ISO 7, ISO 6, and ISO 5 cleanrooms are classifications defined by ISO 14644-1 based on the allowable concentration of airborne particles of a specific size (0.5 microns).

ISO 8 is the least clean, allowing up to 3.5 million particles per cubic meter, suitable for less critical applications.

ISO 7 allows 352,000 particles per cubic meter, often used for manufacturing medical devices or some pharmaceuticals.

ISO 6 permits 35,200 particles per cubic meter and is typically used for high-precision operations like semiconductor manufacturing.

ISO 5 is the cleanest of the four, limiting the particle count to 3,520 particles per cubic meter,

and is essential for environments like aseptic pharmaceutical production or microelectronics assembly, where contamination must be minimized to the highest degree.
